Test Method To test the quality of wireless solar powered alarm wireless beams, we should test 4 parts of the system. They are battery, infrared distance, wireless signal transmitting distance and solar panel charging capability at cloudy and rainy days. A. Test of battery The rate voltage of the battery is 4.2V. If the solar powered wireless beam works at illumination under 1600Lx for continual days and the battery voltage is down to 3.8V, the product will activate battery protection system. It will protect the battery from overusing and the solar powered beams don’t work now. After the battery is recharged to 4.1V, it restart to work. At normal working environment, the battery starts to recharge when voltage is 3.9V and without low voltage protection. Test 1: Working time without sunlight The solar powered beams can work for 20 days without sunlight. Put the beams with battery installed at place whithout illumination such as drawer, box, then trigger it. The day before receiver terminal indicator doesn’t light on is the last working day. Test 2: Battery recharging time At normal sunlight environment, the battery recharging time is 1 day. (from low voltage to full voltage) Put the beam with battery installed at place full of sunlight, take down the battery and test its voltage after 1 day. B. Test of infrared distance The infrared distance of wireless solar powered beams is 100m Install the batteries in beams, aiming and then enroll it to alarm panel. Take the transmitter and receiver beams to 100m distance, aiming again, receiver terminal indicator flash slow then flash fast and then light off. Trigger the beams, the alarm panel send out alarm signal. C. Test of wireless transmitting distance The distance between wireless beams and alarm panel is 100m (can reach to 1 km with high power) Put the alarm panel at a place, enroll the wireless beams to the panel, put the beams at another place which is 100m from the panel, trigger the beams, the panel will alarm. Repeat to trigger the beams to test the stability. D. Test of solar panel charging capability at bad days Amorphous silicon solar panel is used for the beams. It enables the beams to be recharged at cloudy and rainy days. At cloudy or rainy day, put the beam outdoor without battery installed. Place the solar panel towards outside. The beam indicator red LED will keep flashing. That means the solar panel is charging. The solar panel works via absorbing UV light and can work at illumination level is over 1700Lx. The illumination can reach to 2500-2700Lx with sun light and reach to 2000Lx without sun light. Notes of using the solar powered wireless beams 1. Trigger way Only all beams are blocked, the product will trigger alarm. To avoid false alarm by animals and falling down things, the product is designed with required blocking speed. A thicker object such as a book is required for test. Not too fast speed is required to test. Please make sure the receiver indicator lights on when it is triggered. When the product is triggered, the receiver terminal indicator will light on, then light off. Only after it lights off, it will be on work status again for next time trigger. If the indicator is lighting on and now trigger it again, it will not send alarm signal. 2. Aiming If transmitter terminal and receiver terminal are not aimed, the indicator of receiver will keep lighting on. When they are aimed, the receiver terminal indicator will flash slow, then fast and lights off at last. Now, it is at work status. 3. Alarm Panel Antenna of the alarm panel should be pulled out totally to ensure the receiving distance. Remember to enroll the test beams to the alarm panel and arm the panel before test. Avoid to test and use the wireless alarm products at places which is with high magnetism, high voltage equipment or metal objects.

Solar wireless PIR detectors is new generation intrusion detector. It enables DIY home security more easy without wiring and without battery replace in 10 years. Solar power infrared detector is environment friendly electronic security device. Solar power intrusion detector has solved some issues of traditional PIR detector with innovative technology. For example, this new type detector will not be interfered by same frequency band other wireless device. It will not be interfered by bad weather hot days or code days. So, solar PIR wireless intrusion detector is easy to use and more reliable for home security and anti-theft. How can it do? What technology is adopted? 1. Solar power technology Not need to installed outdoor. This detector is installed indoor and powered by natural light, LED light or other indoor weakness light. Not need adequate light source and it even can be installed in dark area. It relies on its large capacity batter (10000mA/h) for power supply. Solar PIR intrusion detector 2. Free false alarm Strong ability to anti-interference with FSK+FHSS signal transmission technology, wireless distance is more than 500m. When send alarm signal to alarm host, it uses multiple frequency band transmission. If one frequency band be interferenced, it automatically turn to another frequency band and without missing alarm or false alarm. Industrial and military material is made of the intrusion detector. It has automatically environment-analysis technology to sense temperature and change sensitivity. Pet identification and CPU analysis enables the pet immunity of this new burglary proof motion sensor. Where is it installed? Different types motion sensors Solar wireless curtain PIR is installed on wall or ceiling to detect intrusion from windows, balcony, gate. Solar wireless ceiling PIR is installed in bedroom, child room, guest room to detect motion in rooms.

There are different beams quantity such as 2 beams, 3 beams, 4 beams, 6 beams and 8 beams of photoelectric beam sensor. So, how many beams should I choose? The more beams means higher of protection height and longer of detection distance. For example, if the distance between two infrared holes is 35mm, then, for 3 beams sensor, the protection height is 70mm. For 4 beams sensor, any two neighbor beams are blocked, it will trigger alarm. Same for 6 beams or 8 beams sensor. So more beams will be with more security such as for bank. More beams means more power of infrared beam transmission and with stronger penetration to against interference of fog, sunshine etc. And what does the infrared detection distance mean? It means the distance between the transmission terminal and receiving terminal. The actual installation distance should be less than 80% of the specified distance. For example, the specified detection distance is 100m, then the actual installation detection distance should be less than 80m. If no interference, the detection can reach to 6 times of specified distance. (6*100=600m). But environment interference should be considered for using. There are some rules for active infrared beam installation. For example, if the beam sensor is installed on a low wall, the distance between the top of the wall and the lowest infrared hole should be around 150mm. Because the size of a normal person is 500mm(width)*200mm(thickness), that will avoid intrusion of people from bottom side of the beam sensor and false alarm triggered by small animals.

The plant area covers an area of hundreds to thousands of square meters, and the perimeter of the fence is more than hundreds meters long. In order to prevent unnecessary losses caused by the invasion of criminal personnel, it is necessary to install infrared beams in the plant area for perimeter protection. Solar energy full wireless infrared beams can be easy used with no wiring and less maintenance advantages. The product adopts solar power supply and wireless communication technology, has the patent certificate issued by the state and 3C certification, CE, FCC and inspection report, and has cases and good reputation in many places in many countries on the world. The perimeter alarm design scheme of the plant: several pairs of solar wireless infrared beams (infrared distance of 100 meters, wireless signal distance of 2-3km) are used in the protection area. In case of illegal invasion, the radio transmitter at the receiving end (S end) of the Beam will send the alarm data to the signal transponder (or frequency modulation transceiver) in the way of radio frequency modulation + frequency hopping with strong anti-interference and long transmission distance ）Each signal transmitter can transmit 50 groups of opposite signals with different addresses respectively, and then transmit the corresponding opposite alarm data to the alarm host at the back end. With the help of the network communication module and the alarm management software developed by the company, the electronic map and corresponding text remarks can be displayed at the PC end, and the whole perimeter alarm system can be installed easy. The host itself has a telephone alarm port, which can timely notify the user’s mobile phone or security center by dialing a phone. If the alarm system needs to be linked with the monitoring video, only one linkage module of our company needs to be added to control the hard disk video recorder by outputting the switching signal, so as to realize the function of alarm pop-up screen.

We regard the detector and alarm host of the security system as the front-end part, from the alarm host to the alarm receiving center as the transmission part, and the alarm receiving center as the back-end management platform part. Once all kinds of triggering events of the user end in the community, such as anti-theft alarm event, smoke fire event, gas leakage event, home water leakage event and emergency help event, etc. Happens, it firstly sends the wireless radio frequency signal to the network alarm host of the user end, the alarm host immediately goes off an on-site alarm in the form of sound and light, and through GPRS traffic, wireless Wi Fi, GSM SMS and wired network, etc., alarm signal is sent. One way of the sent alarm event is transferred to the mobile phone app of the user end and the local property alarm security service center through the server. It displays the specific alarm area in detail, and can view the corresponding video monitoring screen. The other way is transmitted to the management platform of the security alarm center through the direct network, and timely pops up the baidu map, point distribution map and real-time monitoring picture of the incident point Face to face, inform the patrol to handle the situation. It is recommended to install wireless infrared radiation and video monitoring for the surrounding walls and access channels of the community. In case of any illegal intrusion, the alarm information is first transmitted to the alarm host of the local property through high-power radio frequency signal, and then transmitted to the security alarm center and the mobile phones of the personnel on duty through the network. The intruder detectors adopt the independent power supply mode of automatic charging of natural light and timely storage of large capacity batteries, which can work without external power supply. Wireless door magnet and emergency button also use super large built-in lithium battery, without wiring and battery replacement. Once abnormal conditions such as alarm, low power and damage are detected, the detector will actively report to the host of the client in the way of wireless frequency modulation and frequency hopping, so as to truly achieve the all wireless operation mode of power source wireless and signal wireless. The advantage of the design is that the early installation eliminates the tedious trenching and wiring, the after-sales maintenance is simple and convenient, and the safety risks are minimized. https://vedard.com/blog/security-solution-for-community-safety/

Outdoor security protection is the first place to stop burglary and crime. So, outdoor security sensor is important for home security. Most home security systems do not have outdoor security covered. We can easy add outdoor security sensors easy with wireless solar power PIR motion sensor, infrared break beam, garden lighting wall detector, and solar power siren strobe etc. Outdoor security sensors are used to prevent break of windows, gate, fence, balcony. They work as an invisible light wall to block illegal invasion and stop intrusion at outside. Solar power wireless sensors are innovated with new technology FSK and RF wireless encoded communication, self-check and fault report etc. Complete alarm accessories such as wireless repeater for long distance transmitter (more than 1km), wireless to wired transceiver to add all wireless sensors to exist hard wired alarm panel. https://vedardalarm.com/hb-solar-beams-m-3

Conventional fire alarm system is suitable for small places https://vedard.com/blog/conventional-fire-alarm-system-is-suitable-for-small-places/ Conventional fire alarm system is early designed automatic fire alarm system. More complex and intelligent addressable fire alarm and intelligent fire alarm systems are designed later. Conventional fire alarm system is capable of detecting smoke and heat, flame, gas leakage etc. or an activated pull station, and reporting this information to on-site personnel via dedicated phone line. It can identify “zone” which maximum 20-25 detectors in one area are connected to the alarm control panel. Addressable fire alarm system can further identify each detector. So, addressable fire alarm system is popular used for large space or public building fire security. But for small place, such as hotel, villa, resident security, conventional fire alarm system is still suitable and convenient for installation and maintenance. Conventional fire alarm system is reliable as well and it is still used to control relay contact type device such as draught fan, water pump. 2-zone mini type conventional fire alarm control panel is very suitable for small business fire security. It has 2 zones and each zone can equip maximum 25 detectors. The panel has zone1 alarm, zone2 alarm and NAC alarm, zone1 fault, zone2 fault, NAC fault indication. Evacuate, silence, test/reset buttons can be operated on the panel. So, the fire security guard can easy understand the alarm information and operate the alarm panel to warn people of the fire event. Fire location can be easy found and fire extinguishing measure be taken cause the place is small. So, mini type conventional fire alarm system is very suitable for small business place such as hotel, villa, showroom, store. AC90-270V power supply with lead-acid backup battery and 1 alarm sound output zones (bell zones), which can equip max.16 sounders. The mini type fire alarm panel can expand to 4 zones, 6 zones etc. By adding slave alarm panel via RS485 connection. Conventional detector is universal and can be used for any type conventional fire alarm control panel. There are smoke / heat /smoke &heat detectors or 4-wire smoke detector with relay output. The detector can be equipped with shutter door control box as well. When the detector alarms, the signal is fed back to the controller. The remote LED can be connected to the detector for clear view if the detector is installed in hidden place such as attic. Fire control room security guard duty After receiving the fire alarm signal, in 5 seconds, the fire control room No.1 duty officer should confirm the alarm location according to the fire control room graphic display device or automatic fire alarm system corresponding figure. No.2 duty officer should notify and confirm the alarm with the alarm site security person through the fire telephone, intercom, fixed telephone, mobile phone. After fire alarm is confirmed, No.1 duty officer shall confirm the integrated fire control equipment is at the automatic state, if it is at manual state, shall be immediately adjusted to the automatic state. Then should monitor the running state of automatic sprinkler system, fire hydrant system, gas extinguishing systems, foam extinguishing system and smoke exhaust system, fire doors, fire shutter system, elevator, fire emergency broadcasting system, fire emergency lighting and evacuation indicating system. If the fire pump, smoke control fan and exhaust fan are not started automatically, manual control device should be used to start it directly. The fire emergency broadcast system should broadcast to the whole building after fire confirmed. If it is not opened in linkage, the microphone should be used to broadcast to the whole building to inform the specific location of the fire and the way of evacuation, etc., and inform the people in the building to evacuate. No. 2 duty officer shall immediately notify the personnel of the second team and the members of the micro-fire station by means of intercom, fixed telephone, mobile phone, etc., and notify the person in charge of fire safety, fire safety manager, the person in charge of the centralized management department, the person in charge of the fire area department or the person in charge of administrative duty of the day of the unit. At the same time, call the fire alarm number “911”. When calling the alarm, you should specify the name of the fire unit, the specific place, the fire site, the burning material, the fire situation and the contact information.

With the continuous development of social economy, people’s life is improving day by day, people pay more and more attention to the safety of family life and property. According to the different anti-theft area, all anti-theft alarm can be divided into indoor anti-theft alarm and outdoor burglar alarm two categories. Indoor burglar alarm, as the name implies, is installed indoor with various alarm devices. Because the indoor environment is relative stable, subject to fewer external interference, so from the stability feature,indoor burglar alarm false alarm rate is lower than the outdoor burglar alarms. However, because the indoor area is the place where the home owner often moves, it is necessary to frequently arm/disarm the control panel to avoid false alarm from home owner activity. Moreover, consider from the anti-theft side, indoor detectors will cause alarm only when intruders break into the room, and it may be more harmful because of panic. Different from the indoor burglar alarm, outdoor anti-theft alarm installed outdoors and alarms before the intruders enter into the house, so as to scare away the theft and avoid the loss. However, due to the outside installation, there are more requirements for the detectors such as waterproof and extreme weather resistance, free false alarm from sunlight interference and falling leaves etc. Commonly used outdoor detectors and characteristics are as below: I.Electronic fences: Electronic fences can be divided into: pulse electronic fences, tension electronic fences and pulse tension electronic fences. The advantages of electronic fence are: 1.Low false alarm rate. 2.Good environmental adaptability, can be installed on different terrain. 3.High deterrent force. The disadvantages are: 1.High cost of construction. 2.The resulting pulse voltage may cause harm to children and the elders. 3.It can not be installed in flammable and explosive locations. 4.It is easy to let you feel in a cage, and easy to let the rattan plant growing. II.Wired infrared beams It is the photoelectric infrared beam using the cable for power supply and signal transmission. The advantages of wired infrared beams: 1.The use of cable transmission is not easily disturbed by the outside environment interference. 2.Because of the wired power supply, the infrared distance is relatively far. 3.The impact of environmental factors is less. However, there are also many disadvantages of wired infrared beams. 1.Need to dig ditch for wiring, long construction time. 2.High labor costs. 3.With big trouble for system maintenance later. 4.Cables are vulnerable to aging and gnawing by rodents 5.Due to long-term powered, components are easy aging and leading to short service life. 6.Vulnerable to lightning strikes leading to system paralysis. III.Solar power wireless photoelectric beam system The solar power total wireless infrared beam system is an upgrade product of wired infrared beam system. The use of solar panels to power the beam, the use of wireless modules for wireless FM, and even frequency hopping transmission make the beam no wiring. In addition to the advantages of wired beam, the solar power wireless beam also has below advantages: 1.Convenient and short time construction. 2.Easy maintenance in later period. 3.No damage to affect the original building structure, decoration. 4.The use of dot injection technology to extend the life of components and equipment. 5.Less affected by lightning strikes. Of course, solar power wireless beam also has disadvantages. 1.The installation environment has certain requirements. 2.Susceptible to metal structures and high voltage equipment. 3.Susceptible to wireless co-frequency interference. 4.Equipment price is higher than wired beam. 5.Due to different wireless frequencies and different transmission protocols, the system compatibility is not strong. Now there is a kind of solar wireless infrared transmission on the market using frequency hopping technology to transmit signals, so as to increase the original characteristics of wireless anti-jamming ability, to solve the problem of the same frequency wireless signal interference. IV.Solar power wireless light wall Solar power wireless infrared light wall is a supplement of solar power infrared beams. Because infrared beam is basically two beams and three beams, in some special occasions, such as no wall open area, entrance and exit etc. large areas of protection, it needs infrared light wall for security protection. Due to its own protection height of about one meter or more, infrared light wall can be installed in the above areas and prevent intruders to climb or jump over. Moreover, the solar power wireless light wall has built-in horn to scare away the intruders and increase deterrent force. There are 4 beams, 6 beams, 8 beams and 8 beams with garden lamp of wireless solar power infrared light wall. V.Vibrating fiber optic cable The system uses optical fiber as the intrusion detection unit. It has the following advantages: 1.Not need electricity supply, belongs to passive detectors, effectively avoid lightning interference 2.Its single defense area distance up to 500-1500 meters and it is suitable for wide perimeter protection. 3.Compared with the electronic fence, the construction is simple, no digging cable trench, direct laying can be done, and is not affected by the complex terrain;Very suitable for the airport, chemical enterprises, petroleum pipelines, railways, residential areas and various key areas of intrusion prevention requirements. Although vibration fiber has very significant advantages, but his disadvantages are also obvious: 1.The need to pull fiber, the overall cost and construction difficulty is still higher than infrared beams. 2.The distance of each defense area is too large, even if the intrusion is known, it is difficult to locate the specific intrusion location. 3.Real service life is not long, rain and snow corrosion is easy to increase fiber resistance, fiber becomes particularly sensitive, later the false alarm rate rises sharply. VI.Induction cables Induction cables include vibration cables and leakage cables. The induction cables will emit electromagnetic waves and form the defense area, when someone enters into this area, it will cause disturbance and alarm signal will be sent. Electrostatic induction cable has the advantages of pulse electronic fence to block intruders, but also has the advantages of relatively simple installation, convenient wiring, strong adaptability to climate, temperature environment, etc.. But the disadvantages are equally huge: 1. Cables are prone to electric shocks, which in severe cases can paralyze the entire system. 2. Its cost is the highest of all perimeter alarm products. 3. The cable is susceptible to electromagnetic interference. Because of its expensive cost, the main application sites only lie in border line security, communication fiber optic cable protection, airports, oil and gas storage and transportation, prisons, chemical enterprises, oil pipelines, railways and other state organs etc. key areas. Outdoor zone detectors I.Radar detector Radar detector is designed to detect the above-level radar waves and use sound, light to scare away the intruder. Radar detectors have the advantage of being small and not easily discovered by intruders. And the use of radar principle, can reach 360 degrees of all-round protection. It has strong penetration and can penetrate the general wooden barrier for detection. The disadvantage of radar detectors is that they are susceptible to clutter and have high requirement of the mounting area. Because as long as there is an object moving in the detection area , it will trigger alarm. So it should be installed on a stable base and the detection area is relatively stable, there is no frequent object movement. (2) Outdoor infrared detector Wired outdoor infrared detector Wired outdoor infrared detector used to detect intrusion via infrared thermal radiation of moving object. The advantages of wired outdoor infrared detector is: 1.Power supply is stable and without low power problem. 2.Size is small with good concealment, not easy to be found and destroy. However, the wired passive infrared detector also has the following disadvantages: 1.The signal amplitude is small, easy to be disturbed by various heat sources, light sources. 2.Poor penetration, the infrared radiation of the human body is easy to be blocked and not easy to be received on the receiver beam side. 3.When the ambient temperature is close to the human body temperature, the detection sensitivity decreases obviously, sometimes causing short-term failure. 4.The main direction of motion detected is the transverse direction of motion, and the ability to detect objects moving in the radial direction is poor. 5.The wiring may destroy the original decoration, later maintenance is more troublesome. Wireless outdoor detector Wireless outdoor infrared detector is upgraded from the wired outdoor infrared detector. Battery power supply and wireless transmission module is used for the detectors. The advantages of wireless passive infrared detector: 1.Easy to install, no wiring needed. 2.No wiring and no destroy of house decoration. 3.Easy for maintenance. Although the wireless outdoor infrared detector has significant advantages, but its disadvantages are also obvious: 1. Need to replace the battery regularly. At least once a year need to replace one battery. 2. Infrared detector wireless alarm signal is easy to be interfered with, for example, multiple detectors are installed nearby, then the wireless signal sent by the detectors will interfere with each other and the receiver alarm panel can not receive the alarm signal. 3. The wireless signal transmission distance is relatively short, generally around 100 meters, if there is a wall block and metal objects influence, the wireless transmission distance will be closer. Light energy hopping frequency wireless outdoor infrared detector This is a new product, first of all, it uses light energy combined with the battery to power the outdoor infrared detector, solved the problem of outdoor passive infrared detector power supply. No need wiring or frequent battery changes. And secondly, it uses the wireless signal transmission method of frequency hopping, solves the problem of wireless signal interference between ordinary outdoor infrared detector, from a technical level it has indeed made disruptive progress. However, to make this kind of products stable, the manufacturer’s research and development and production requirements are relatively high. Only a few relatively professional alarm manufacturers in the market has the products in the production and sales. Its advantages: 1, light energy combined with the battery power supply greatly improved the usage of outdoor infrared detector cycle. It will use natural light for power supply, or use battery power when there is no natural light. 2, It adopts frequency-hopping wireless signal transmission technology to solve the problem of wireless signal interference between ordinary wireless outdoor infrared detectors. The frequency-hopping technology enables the wireless signal to send out via multiple channels when moving object is detected. So even if one of the channel is disturbed, the alarm signal still can be sent out to the alarm receiver timely and stably via other channels. 3.The wireless transmission has longer distance and better penetration. Although this kind of light energy hopping frequency wireless detector has a lot of progress compared with wired detector and wireless detector, but it still has some advantages: Firstly, the price is relatively high, because of the addition of some additional components and materials, and the lack of competition of these new products. Secondly, The compatibility is not strong, because the frequency hopping technology is designed to prevent interference between wireless signals, so it is not directly compatible with the other alarm system. Motion detection function of surveillance camera Now most cameras are with function of motion detection and alarm. It compares the monitoring screen to determine whether there is an intrusion. Professional motion detection surveillance camera is with less false alarm and faster response, but the product is very expensive. The relatively low price surveillance camera with motion detection alarm will have high rate false alarm. Because it uses the current picture and the comparison of the last screen to determine whether there is an intrusion, so even a leaf can trigger alarm. With the development of science and technology, now there are more and more types of outdoor anti-theft equipment. Each manufacturer’s products also have their own advantages and disadvantages, users should choose the corresponding alarm equipment according to the location and environment security needs.

Firstly, The central system failure. 1. The central machine can not receive all users alarm information. Possible causes: telephone line interference is too large, telephone line noise, telephone line short circuited or open circuited, telephone anti-theft switch is turned on, communication failure of the telecommunications bureau, host alarm center communication programming error, center software serial port closure, serial line connection error, serial damage, the failure of the computer itself may lead to the center machine can not receive alarm information. Solution: check whether there is a short circuit and open circuit on the telephone line, turn off the anti-theft switch on the telephone, check whether the central communication programming of the user-side host is correct, including (center phone number, center communication level, central communication format, user number, reporting options, etc.); Check if the central software is a trial and query the system logs to check the software expiration period. 2. The center machine received alarm information, but can not pop up on the software. Possible cause: The user information does not exist in the central software. The serial port is closed, the serial line connection error, the serial port damage may cause the center machine to receive the alarm message, but can not pop up on the software. Solution: Add user information to the central software, open the corresponding serial port, connect the serial line correctly, check whether the serial line interface is damaged. 3. The central machine received the alarm information, but the alarm information can not be uploaded or downloaded. Possible causes:the central telephone line interference is too large, the telephone line appears short circuit, open circuit, telecommunications bureau communication failure. Forwarding number in the center software is not filled correctly may cause the center machine to receive alarm information, the alarm can not be transmitted up/down. Solution: Check whether the telephone line interference is too large, the telephone line has a short circuit, open circuit, correctly fill the forwarding number in the center software. Secondly, the alarm host system failure. 1. The alarm host is armed or forced to armed and the wired detector is triggered, but the host does not alarm. Possible causes: Wired detector and alarm host connection line error, line short circuit, open circuit, detector supply voltage is insufficient, end-of-line resistance missed or wrong wired, zone properties are not edited or edited error, etc. may lead to the alarm host does not alarm after the detector is triggered. Solution: Check the cable connection between the detector and the alarm host. Check whether the end-of-line resistor is not connected or wrong connected. Use the meter to test whether the line is short-circuited, open circuit, detector power voltage is stable (cannot be less than 9V) and so on. If the zone is not correctly programmed, should correct it. 2.The alarm host does not alarm after the wireless detector is triggered. Possible reasons: wireless detector battery power is low. Wireless detector code is not correct, or messy code is learned into the alarm host. The wireless detector learned into the alarm host is not programmed with zone properties, or zone properties are wrong edited. The distance between the wireless detector and the alarm host exceeds the rated transmission distance. There is metal barrier between the wireless detector and the alarm host. Solution: replace the battery. Re-code the wireless detector to the alarm host. Program the zone properties of the detector zone. Shorten the distance between the wireless detector and the alarm host. If there is a metal barrier between the detector and the alarm host, then re-adjust the detector installation location. 3.The alarm host can not receive high-frequency signal, why? (including remote control and wireless converter) Possible causes: The remote control battery is low or the converter is not powered on. The wireless code of the remote control and wireless converter is not learned to the alarm host, or is too far away from the host. The host failure to decode etc. Solution: replace the battery or change a remote control to test, correctly program to learn wireless code, shorten the distance between the remote control and wireless converter and the host. If multiple remote controls can not be learned into the host, that means the alarm host may have problem of high-frequency reception and need to return to manufacturer for repair. 4.The alarm host false alarm. Possible cause: The possibility of false alarm caused by the alarm host is very low. Because the host is only a signal receiving processor, and even if there are false alarms, most of them are caused by detectors. Unless the voltage fluctuation is too large may lead to host false alarm. When false alarm occurs, please check the detector status. Solution: First confirm the false alarm zone and detector, and then check the detector. 5.The alarm host is in normal use but it makes a sound without any reason. Description: The chimes of the host can be divided into beeps, fault chimes, guard exit delay tones, alarms into delay tones. Solution: Please confirm what kind of chime the host is making. If there is no any operation on the alarm host, the sound could be a fault detected by the alarm host. Please check further indication of the fault and solve it. 6.The alarm host connects to the external alarm horn, but when alarm goes off, the external alarm horn does not make sound. Possible causes: the positive and negative wire between the horn and the host is opposite. There is short circuit or open circuit of the host and horn link. The host output voltage is not enough (about 12V). The external alarm horn is not programmed or correctly programmed into the alarm horn. Solution: Check whether the wire connected to the alarm host and horn is correct. When the host is alarming, test the host’s external alarm interface voltage and it should be 12V or above. If there is no output, that means the external horn is not programmed or PGM output is not open. If the above operation is correct and still no sound from the alarm horn, then please replace a horn and test. 7.The alarm host does not dial telephone phone or mobile phone to notify the alarm. Possible reasons: telephone line interference is too large, telephone line short circuit or open circuit or telephone anti-theft is turn on. The phone number is not programmed or correctly programmed to the alarm host. (including communication phone number, format, report level such as alarm report, fault report). Solution: check whether the telephone line interference is too large, check whether the telephone line has a short circuit, open circuit problem exists, confirm whether the connected host’s telephone line needs to dial code before dialing the outside line phone. if need, please enter the code before the telephone number. Otherwise re-program the alarm receiving number correctly. 8.The alarm host does not communicate with service center after alarm. Possible causes: Large interference of the telephone line caused the failure of data transmission. The host connected telephone line short circuit, open circuit. Programming process wrong of service center communication telephone number, communication format, communication level, user number etc. Solution: Check whether the telephone line is short-circuited, open circuited. Correctly program the central communication telephone number, the central communication level, the central communication format, the user number. If all of the above is normal large telephone line interference maybe the cause. The central communication is a data transmission, different from the general voice transmission, if the telephone line interference is too large it will lead to unreliable communication. The engineer can do the following process to tests. 1.Listen to the telephone receiver, if there is a significant noise, you should find the communication company to solve it. Because the telephone line interference will cause the alarm host data transmission error. Use a multimeter DC voltage range to test the following parameters for telephone lines a. Empty voltage: When the telephone handset is not picked up, measure the DC voltage on the telephone line to see if it is 43 to 53 volts. b. Pick up voltage: Pick up the telephone handset, measure the voltage on the telephone line, to see if it is 6 to 10 volts. C. the resistance voltage: Parallel a 300 ohm resistor on the telephone line, measure the DC voltage on the telephone line to see if it is 6 to 12 volts. After testing, do the following based on the test results: a. If all the voltages tested meet the requirements, the line is OK and the alarm host should be replaced for a try. (The replacement alarm host must has been actually tested to the center communication and is very reliable, otherwise it may cause misjudgment) b. If the voltage is not normal, but deviation is not much, you can series a 100, 200 or 300 ohm (1/4 watt) resistor on the telephone line to try it; c. If the voltage is not normal and exceeds too much, or if the test according to B method does not solve the problem, please send the host back to our company together with the parameter records of the test. Our technical engineers will specifically modify the host circuit parameters according to the user’s phone line parameters to accommodate the telephone line. Thirdly, detector failure 1. Beams a. After the infrared beam is connected to the host and the host is armed, trigger the beam, but the alarm host does not alarm. Possible causes: there are blocks between the two beams; the beam and the host connection is wrong; the beam tamper switch is not closed; the line has a short circuit, open circuit, insufficient supply voltage, beam zone properties are not programmed correctly. Solution: correctly connect the line and end resistor between the beam and the alarm host (the connection and size of the resistor depends on the host used), check the line for short circuits, open circuit, test whether the power supply voltage of the beam is larger than 9V, check whether the alignment light on the transmitter end is off. Flashing or long light of the transmitter is not normal, reprogram the beam’s zone properties correctly. b. During the initial installation and debugging of the beams, the alarm goes off when the alarm host is disarmed. Possible cause: The beam is with open circuit and the zone property is set to a 24-hour zone. Solution: Check the beam circuit and correctly connect it. c. Why is the alignment light of the beam flashing or keeping on? Possible causes: the synchronization wire connection is wrong, the receiving end and the transmitter end are not aligned, the receiving end and the transmitting end distance is too far, there are blockers in the detection area, the supply voltage is insufficient, the receiver’s tamper switch is not closed. Solution: Correctly connect the synchronization wire; Check whether the tamper switch is closed; Adjust the angle between the receiving end and the transmitter to align it; Ensure that the supply voltage is above 9V. d. The beam false alarm Possible causes: the power supply voltage floating up and down too large, environmental causes. Intermittent short circuit caused by wire flooding. Solutions: Ensure that the supply voltage is above 9V; Check whether the wiring is normal. Replace the false alarm beam with the correctly working alarm beam to check whether there is environment interference. 2. Detectors (wired, wireless) a. After the detector is connected to the alarm host and the host is armed, trigger the detector, but the alarm does not goes off. Or the alarm host can not be armed caused there is zone error. Possible causes: Wired detector and alarm host connection wrong; detector tamper-resistant switch is not closed; There is short-circuit or open-circuit; The supplied power is insufficient; The detector or the zone property is not correctly programmed. Solution: correctly connect the wire and end resistor between the detector and the host (the connection and size of the resistor depends on the host used), check the line for short circuits, open circuit, test whether the supply voltage of the detector is larger than 9V. Check whether the detector alarm light is off when the tamper-resistant switch is closed. Reprogram the zone properties of the detector correctly. b. During the initial installation and debugging of the detector, the alarm goes off when the alarm host is disarmed. Possible cause: The detector is with open circuit and the zone property is set to a 24-hour zone. Solution: Check the detector circuit and correct it. c. False alarm of the detector. Possible causes: Passive detector is used to detect changes of environmental temperature difference and makes alarm, sensitivity adjustment is not correct, detection of environmental temperature difference changes may lead to false alarm. Solution: Check whether the line is intermittent short circuited caused by water. Adjust sensitivity and installation position appropriately. Check whether the supply voltage deviation is too large, replace the false alarm detector with the good detector to check whether it is the environmental cause. d. After the wireless detector is installed, arm the alarm host and trigger the detector, but the alarm host does not alarm. Possible causes:Low battery power, incorrect or no wireless code is registered. Incorrect or no program for the zone property during programming. Solution: Ensure that the battery voltage is correct. If not, replace the battery. Re-code the wireless detector and program the zone properties. e. the detector’s trigger light flashes, and the host also emits a fault chime? Possible cause: The wireless detector battery is low. Solution: Replace the detector battery. 3.Wireless door magnetic contact The wireless door contact is installed and alarm host is armed, but it does not alarm after the door contact is triggered. Possible causes: Low battery power, incorrect or no programming wireless code, incorrect or no programming for the zone property during programming. Solution: Check that the battery voltage is correct, replace the battery if not normal, re-code the wireless door magnet and zone properties programming. b. Why is the wireless door magnetic contact makes false alarm? Possible cause: The mounting gap between the magnet and the motherboard is at the alarm edge. Solution: The installation gap between the magnet and the motherboard is best not to be greater than defined. Adjust it according to the gap fluctuation of the installed position.

1. The linkage between the access control system and the fire alarm system In places with a large flow of people, it is more difficult to evacuate people in emergency situations such as fire alarms and terrorist attacks. This problem is especially obvious after the access control system is installed in these places. It has become a major obstacle for people to escape. Therefore, the access control system must have the function of fire and fire linkage. The signal output by the fire alarm system is usually a passive dry contact signal, and the linkage between the access control system and it can be realized in two ways. First, directly power off the electric lock controlled by the access control system. The fire-fighting system can be directly connected to the relay (it should be pointed out that when the relay does not have a fire alarm signal, the coil should be in a power-off state, so as to extend the life of the relay) to control the power supply of the electric lock of the access control system, that is, the relay is normally open The contact controls the 220V power on and off. When a fire alarm occurs, the relay will act in time to forcibly power off the access control system’s electric lock power supply (mains and backup power) so that the designated door can be opened automatically when the system is powered off . The advantage of this method is that it is simple to use, but the controller does not have access to the alarm signal, nor does it save the corresponding records. Second, the logical judgment linkage of the access control system (indirect linkage). The alarm signal of the fire alarm system directly communicates with the linkage expansion port of the access controller. This method can realize the input functions including the fire alarm signal input, the glass breaker alarm signal input, and the sound and light alarm signal output, and the forced electric lock Action output and other functions. In the event of a fire, the access controller will receive the fire alarm signal transmitted by the fire alarm system in the form of relay dry contacts (the fire system actively sends the signal, and the access control system passively receives and executes the control), so as to control the designated according to the prefabricated linkage command The electric lock is automatically opened or closed to facilitate the normal evacuation of personnel and achieve the purpose of escape. At the same time, some doors are closed to prevent the spread of fireworks. In order to further emphasize the safety of the passage and prevent someone from deliberately creating false fire signals to automatically open the electric locks and causing escape accidents, the access control system can be set to multi-channel fire alarm signal input authentication mode, which can be set to receive multi-channel fire protection A designated door (such as fire access doors on each floor) is opened when an alarm signal is issued. If only a single alarm signal input is detected, no action command will be issued to the electric lock, but the normal legal exit process can still be The electric lock is opened. 2. Linkage of access control system and video surveillance system Video surveillance is an important subsystem in the security system, and it is also a necessary security equipment for any large-scale public place. The access control system can cooperate with the surveillance system camera, matrix or NVR to realize the image capture and monitoring functions of the controlled access control points. The linkage between the access control system and the video surveillance system can be achieved in two ways: The first is the hardware method, which uses the dry contact of the access control system output relay to the matrix alarm input module of the monitoring system and the alarm input terminal of the NVR to realize the image capture and monitoring function of the controlled door or related parts. This type of linkage is the most commonly used and the most basic in the past. The second is the software method, which has an access controller that supports the function of a digital video server (encoder), and simultaneously realizes the dual data exchange function from the equipment protocol layer to the software database layer with the digital monitoring system. There is also a software method, that is, directly write the access control management system software into the SDK of the video capture card in the NVR, and associate it with the NVR device through the access control software software function item. The above two software methods have their own advantages and disadvantages. The former has the advantage of fast system response and no delay. The disadvantage is that the video data must be stored in the local management host, which requires a higher capacity for the host’s hard disk. The advantage of the latter is that the local management host does not need to save the video stream data, but only call the data in the remote NVR when needed. The disadvantage is that the associated video will have a delay of about 1-3 seconds, and it cannot deal with abnormal conditions at the channel. The previous video is called. The video surveillance of the access control system can achieve the following three functions: 1. Video recording The access control system actions that it can be associated with include the removal of the controller or sub-devices, illegal door opening, door opening timeout, coercion to open the door, invalid card, card opening, button opening, disarming, arming, various other alarm conditions, etc. If the above signal is detected, it will immediately start the video surveillance equipment to record the event at the channel site. The recording time can be set freely (usually including video recording before, during and after the event), and the management host will be real-time Reflect the recorded information on the monitoring interface of the access control software. According to actual needs, the video recording data can be stored in the local management host or in a remote NVR. 2. Video capture The same as the actions that can be associated with video recording, the difference is that this function item only captures the video of the event and the captured image is the real-time information of the event. 3. Status monitoring This function requires that the management host of the access control system must be in the on state (the video surveillance system can be on or off according to the actual function of the access control product), and the real-time monitoring screen of the access control software is consistent with the screen at each channel. The operator can synchronously observe the status of the channel scene through the monitoring screen, and its function is similar to the monitoring function of the NVR. Three, access control system and intelligent building linkage The linkage between the access control system and the intelligent building is mainly realized through the relay on the access control controller or the external relay of the system, that is, all the digital actions in the building management system are equivalently converted into the card swiping actions in the access control system. The essence is The card swiping action is associated with the relay or external relay action on the access controller, so that the relay outputs a digital signal to control or manage various equipment in the building system. The linkage between the access control system and the building system is mainly reflected in the following three aspects: 1. Linkage with building intercom system The linkage between the access control system and the intercom system is a parallel linkage. This linkage method is mainly to integrate the access control system into the building intercom door machine to realize the function of swiping the card to enter the door. The mutual correlation between the two is shown as a pure hardware connection. . And this linkage basically does not have any technical difficulty, as long as there is a reserved space in the intercom host to install the access control panel, the “intercom + access control” function can be fully realized. 2. Elevator control linkage The access control system and the elevator linkage control mainly realize the following functions: make the public elevator a dedicated elevator for the owner, enable users to swipe the card to use the elevator (need to press the floor number key), and after the user swipes the card, the elevator reaches the designated level of the building (no need to press the floor number key), reduce elevator misoperation and idling, effectively reduce loss, reduce elevator maintenance burden, and save maintenance costs. After registration, the administrator will issue a temporary access card or use the password set by the defendant to make the elevator reach the designated floor. The essence of its function is to convert the switch input of the elevator buttons to the switch of the relay on the access controller. For quantity input, the action of swiping the card replaces the action of pressing the key. 3. Intelligent energy management Through the powerful external linkage function of the access control management system, automatic energy management of the office environment can be realized. When going to work, the air conditioner and lighting equipment are automatically turned on by swiping the card action, and the air conditioning and lighting equipment are automatically turned off by the swiping card action at the end of work to save energy. At night, the building landscape lighting equipment is automatically turned on by the relevant operation of the access control system, and automatically turned off in the morning, etc. If needed, it can also automatically control other electrical equipment in the office. It can be set at will for 24 hours, automatically cycle, and the time period is accurate to the minute. The realization of this linkage mode is mainly realized through the host computer management software, the internal relay of the controller or the external relay. The principle is also to use the switch output of the relay associated with the access controller to control the AC contactor of the electrical equipment. Buttons or other ways to achieve control of electrical equipment.

Inspect the system lines according to the requirements of the corresponding construction, for the fault lines, open, empty welding, the problem such as short circuit, insulation resistance is less than 20 m Ω, corresponding treatment measures should be taken. Respectively electricity inspection for single machine is required for fire alarm controller, fire linkage controller in the system, the combustible gas alarm controller, electric fire monitor, gas (bubble), fire extinguishing controller of electrical control equipment, fire fighting equipment, emergency power, fire emergency broadcasting equipment, fire special telephone, fire alarm transmission equipment or user information transmission device, fire control room graphic display device, fire, fire shutter controller, electric actuator area monitors display panel (fire), fire emergency lighting control, fire door monitor, fire alarm device. Firstly, Fire Alarm Controller Before debugging, all external control lines of the fire alarm controller should be cut off, and the power should be switched on after connecting the fire detector of any bus circuit and the manual fire alarm button and other components on the bus circuit. According to the relevant requirements of the fire Alarm Controller standard, the following functions of the controller shall be checked and recorded one by one by means of observation and instrument measurement, which shall meet the following requirements: 1.Self-check function and operation level Make the connection between the controller and the detector open or short, and the controller should send fault signal within 100s (except fire alarm signal in case of short circuit);In the fault state, make the detector in any non-fault part send fire alarm signal, the controller should send fire alarm signal within 1min, and record the fire alarm time;Then make other detectors send fire alarm signal to check the controller’s alarm function again. 2.Mute and reset functions Make the connection between the controller and the standby power cut off or short. The controller should send a fault signal within 100s. 3.Check shielding function Short-circuit any point within the protection scope of the bus isolator and check the isolation and protection function of the bus isolator. 4.Make at least 10 fire detectors on any bus circuit in the state of fire alarm at the same time to check the load function of the controller. 5.The automatic conversion function of main and standby power supplies, and the inspection of article 4 shall be repeated under the condition of standby power supply. 6.Other functions specific to the alarm control panel 7.Connect the other loops to the fire alarm controller in turn and repeat the inspection Secondly, point type smoke and heat detector 1. Check the alarm function of each fire detector one by one by using the special detection instrument or the method of simulating fire. The detector should be able to send fire alarm signal. For unrecoverable fire detector, simulated alarm method should be adopted to check its alarm function one by one, and the detector should be able to send fire alarm signal.When there are spare parts, can sample check its alarm function. 2.The alarm function of each household fire detector shall be checked one by one by means of special detection instruments, fire simulation or pressing the detector alarm test button. The detector shall be able to send sound and light alarm signals, and the connected detector shall send sound alarm signals. Thirdly, linear type heat detectors Simulate fire alarm and fault on the unrecoverable detector, check the fire alarm and fault alarm function of each fire detector one by one, and the detector should be able to send fire alarm and fault signal respectively.The recoverable detector can be made to send fire alarm signals and simulate faults by means of special detection instruments or fire simulation. The fire alarm and fault alarm functions of each fire detector can be checked one by one. The detector should be able to send fire alarm and fault signals respectively. Fourthly, linear beam smoke detector Adjust the optical regulating device of the detector one by one, so that the detector is in the normal monitoring state. Block the optical path with the optical dimmer of 0.9dB, and the detector should not send fire alarm signal. Block the optical path with a dimmer rate (1.0dB ~ 10.0dB) set by the product manufacturer, and the detector shall send fire alarm signal. Use a dimmer with a dimmer rate of 11.5dB to block the optical path, and the detector should send fault signal or fire alarm signal. When selecting reflection-type detector, the detector should be checked at 0.5m in front of the detector according to the above requirements, and the detector should respond correctly. Fifthly, line sampling suction smoke fire detector Add test smoke one by one into the sampling hole at the end of the sampling tube (the most unfavorable place), and use stopwatch to measure the alarm response time of the detector. The detector or its control device should send fire alarm signal within 120s. According to the product manual, the airflow of the sampling tube of the detector is changed to make the detector in a fault state. A stopwatch is used to measure the alarm response time of the detector. The detector or its control device should send a fault signal within 100s. Sixthly, point fire detector and picture fire detector The detector’s alarm function should be checked one by one in the most unfavorable part of the detector’s monitoring area by special detection instrument or fire simulation method, and the detector should be able to respond correctly. Seventhly, Manual fire alarm button Apply appropriate thrust to the recoverable manual fire alarm button to make it act, and the alarm button should send out fire alarm signal. For the unrecoverable manual fire alarm button, the method of simulating action should be adopted to make the alarm button act (when there are spare parts, the action test can be conducted by sampling), and the alarm button should send out the fire alarm signal.

When intrusion is detected, it will trigger the camera to turn to the view and take the picture then send to home owner or security service mobile. Smart security system can assist home owners and security service guard to monitor the home security 24 hours. How to design the home security solution? Firstly, we need to analyse the function requirements. 1.What system is needed? Access control, CCTV, intruder alarm with fire detection all three systems are needed or not? Will the 3 systems work together on a platform for management together or separately? 2.What network to use for alarm sending? PSTN, GSM/GPRS 3G/4G, TCP/IP? 3.What type of alarm information sending and how to monitor the security system? Voice call, email, app prompt, sms? Need to send image and monitor the protected area video or not? 4.Need to remote control house appliance? If yes, need to add the smart socket. Secondly, we need to analyse the application requirement. 1.How many windows? Need to use windows contact switch or curtain PIR or both? 2.How many doors? Need to use door contact. 3.How many floors? Need to use PIR motion sensor at at the top of each staircase. 4.What is the longest distance between sensor with alarm panel? If more than 100m, then wireless repeater is needed. 5.How many siren strobe to use? Each floor can have one installed. 6.How many smoke detectors to use? Every bedrooms, staircase, living room should have the smoke detectors installed. 7.How many gas detector to use? At least the kitchen room should have the gas detector installed. 8.How many security camera to installed? The garden, courtyard, balcony, the gate entrance, all floors staircase should have security cameras for monitoring. 9.More other security sensors such as CO detector, heat detector, water leakage detector, panic button can be added according to needs. 10.Outdoor security protection of fence, garden, wall, windows and balcony. New technology solar power wireless infrared break beam, infrared grating and outdoor solar power PIR motion sensor can be used for outdoor security easy. If use outdoor windows infrared grating, then the indoor windows contact or motion sensor can be removed. Building terrace, balcony, French window is the key area of safety protection. Solar power wireless break beam system can be used for the protection. The security protection areas can be divided into indoor security area, outdoor security area and perimeter security area. The key security area may have double types security equipment such as security camera and infrared grating installed. Security system can be set arm/disarm timer and automatically armed disarmed. Other alarm accessory such as remote controller, keyboard can be used to send alarm, receive alarm information and inquiry system status easy. The selection of wired, wireless or combined security system. Wired security system is composed of wired alarm host and various kinds of detectors. When installing wired safety systems, it is necessary to groove in the floor or walls to embed galvanized steel pipes or PVC pipes during building decoration or installation. It is generally suitable for hotels, offices and apartments. It is not suitable for house with many rooms or protection areas. Wireless security system is composed of wireless defense alarm host and various wireless detectors through RF radio frequency communication. Wireless security systems can easily add or change detection point and detectors. It greatly reduce wiring construction cost and labor cost. Its disadvantage is uncertain of the stability of signal transmission. Combined security system is always adopted for security project. In addition, the video monitoring transmission data is very large, alarm, monitoring integration host can not bear. So video surveillance is generally a separate system. Home security solution design provisions: 1.Safety and protection engineering procedures and requirements. 2.Technical standard for burglar alarm controller. 3.Technical standards for intrusion detection. 4.Fire prevention requirements for homes. 5.Home security system standard.

Intelligent lighting system, such as: touch switch, multi-function control box, the purpose is convert non intelligent products into intelligent products, such as the lamp is not intelligent, plus the multi-function control box can be arbitrarily converted light brightness, color, switch state, etc. 2. Environmental detection system, such as: temperature and humidity sensor, the purpose is to detect indoor temperature changes, if the temperature is too high or too low, will automatically turn on the air conditioning, after the temperature and humidity adjusted to comfortable value, air conditioning automatically closed. 3. Smart home appliance system, such as smart jack board, smart socket, etc., can control the switch status of smart home devices by mobile APP, and support WiFi connection. If the phone needs to be charged, it will power off automatically after setting the time. 4. Window curtain control system, such as: door and window sensor, opening and closing curtain motor, mainly control the curtain, for example, the alarm clock in the morning, the curtain will automatically open, if also linked with the rice cooker or coffee machine, it will automatically start to work. 5. Intelligent AV system, such as: intelligent remote control, infrared repeater. Their main function is the unified operation of infrared home appliances. Save the trouble of pressing buttons. Home security includes 1. Intelligent door lock system, such as: face recognition lock, intelligent password lock. Features include remote unlocking, password unlocking, face recognition unlocking, swipe card unlocking, key unlocking five unlocking methods. 2. Intelligent infrared detection system, such as: water detector, combustible gas detection, smoke alarm, intelligent high-definition camera, body sensors and other equipment, are identified by infrared thermal sensing, such as danger, the system will send text messages, notify the user to deal with in time. In addition, the biggest advantage of smart home security system is that it can realize the linkage operation between major equipment - automatic intelligent control. For example, open the home mode. When you open the door, the porch light automatically turns on, the air conditioner automatically adjusts to the right temperature, and the TV also switches to your favorite channel. The biggest intelligence of smart home is not remote control on mobile phones, but the interaction between devices, so that the device can better serve life. Security system is the biggest intelligent system, when it finds the security threats, it can immediately deal with it and family security can be seen remotely.

Source from https://vedardalarm.com/new-equipment-for-outdoor-security-ezp-63 We can't ignore the yard, driveway, fence security precautions now. For home security, open doors and Windows detection, indoor intrusion detection are strictly deployed. However, there is often no monitoring of such acts as climbing over walls, lingering in courtyards and stealing. This is mainly due to the difficulty of installing outdoor detectors. Outdoor detectors generally adopt infrared beam to meet the needs of large space. Traditional infrared beam is wired type. Long-distance wiring from outdoor to indoor is no small project. Therefore, general home security does not do outdoor intrusion monitoring. The improved solar wireless beam is easy to install. There is absolutely no need for wiring. Digital display calibrator is used in the transmitting and receiving end of infrared beam, which makes installation and calibration convenient. Infrared beam can be mounted on walls, and a pair can cover a distance of 50-80 meters. infrared grating can be used for protection of 10 meters away, such as Windows. For protection from distances of 15 to 20 meters, such as driveways, courtyards can be equipped with solar detectors. The solar outdoor wireless detector can detect and prevent illegal intrusion and suspicious behavior in time. General personnel can properly install and use solar detectors with instructions and video guidance. Through the alarm host, the intrusion behavior can be sent to the app alarm.

Source from https://vedard.com/blog/new-way-to-enhance-security-in-public-places Precautionary warning is the most effective way of safety. It warns people before they engage in dangerous behavior. At the same time, it sends an alarm signal to the security personnel’s mobile phone. So dangerous behavior can be prevented. Security personnel can enhance security measures such as patrols. People are concerned about their safety in public places such as schools, malls, and airports due to the rise in mass shootings and terrorist attacks. Theft, vandalism, and violence causes huge casualties and property losses. Physical security system is the effective way to detect and prevent crimes. The solar wireless beam is composed of transmitting terminal and receiving terminal. Mount the infrared beam on the entrance and exit of the protected area or the protected wall, then an invisible protective line is formed. Infrared light can be emitted from 800 meters to 1,000 meters. No power and signal cables are needed to wire. The solar wireless beam system can be easily installed in airports, schools, orchards, aquaculture farms and more. Solar beams can be installed in schools, gyms, museums and community around the perimeter. Abnormal climbing and approaching behavior will be detected and alerted. It can ensure the safety of public activity places. According to the environmental characteristics of the protection site, solar beam security system can be installed on the outer wall or fence. Places such as detention centers, explosives depots, chemical and petroleum warehouses need to be closely supervised. It is monitored 24 hours a day by a solar IR security system. The solar infrared safety system adopts high precision production process and technology to ensure safety and reliability. The system can automatically detect and send error reports to prevent man-made or natural damage. Solar wireless beam system can be installed in orchards, forests, and aquaculture farms to prevent theft, arson, poisoning and other illegal acts. configured with app alarm receiver, solar wireless beam can report intrusion to app. Fruits and aquatic products in the wilderness and construction materials and personnel safety in construction sites can be protected. The solar beam works with a surveillance camera to upload pictures of the theft and damage to the user’s mobile phone. Wrongdoers are punished for their actions and owners are compensated for their losses. You can watch, study and follow the solar installation video guidance on youtube. https://www.youtube.com/watch?v=p7kv9E7VLhg

Intelligent security operation management software is integrated alarm management and video surveillance system. It supports the system integration of alarm equipment, access control, and integrates video surveillance, alarm system, intercom system, etc. Based on the actual application of various industries, the software has functions of alarm user management, real-time alarm handling, scheduled tasks, data query statistics, electronic maps, hierarchical management, and multiple ways to push messages, etc., and basic video surveillance functions such as preview, playback, centralized storage, alarm linkage, zone map, alarm verification, etc. Why is intelligent security system management software important? How is it different from a security monitoring APP? In addition to APP’s functions of alarm Settings, alarm information push viewing and monitoring, the PC software also has security system abnormal alarm, electronic map and other functions. 1.Query statistics: Support mainly includes data query, event query, document query and other queries. In addition to supporting common shortcut queries, the query mode also supports fuzzy query and accurate query, and selects query according to different contents, which is more powerful and richer in content. 2.Real-time alarm enforcement: Support alarm management, video linkage, electronic map, video preview, convenient for on-duty officers to view maps or video images while handling alarm situations. 3.User control: Remote back control of users, operation to view the number of current online, offline, arming and disarming users, but also can quickly view user information and related events and other operations, and can also directly carry out remote disarming, bypassing, etc. operations on the host. 4.Video management: Support common IPC and fluorite equipment access platform, realize video storage, preview, recording, playback, alarm linkage, nuclear alarm, PTZ control functions. 5.Device management: Support alarm host, emergency alarm equipment, video equipment, intercom equipment, and manage by querying and counting user status, and count the current status of the device according to the information reported by the user’s front-end device. Intelligent security system in addition to equipment to work reliably, accurately judge the intrusion, harm events and timely alarm and processing, it also needs to ensure that the equipment is not destroyed. Like other smart devices, such as self-driving cars, smart security systems can be compromised by various human or radio interference, causing them to fail to work properly. So, devices check and fault alarm is what the PC software will do. The AC power failure, detector missing, low battery, door sensor open status etc. will trigger alarm. You can set hard-disk check, storage full alarm, video channels missing alarm and video surveillance image missing alarm. So, any vandalism will be detected and alarm will be sent. Logs of alarm records and device operation records are uploaded to the software. These logs and other records can be uploaded and stored on the server via FTP. It enables the security service personnel to check in time, and troubleshoot hidden dangers. So, the intelligent security system management software is important. It is the guarantee that the security system can work reliably without missing alarm. It is convenient for security service personnel to easily and accurately understand the running status of the security system and security status.

Security system is mainly divided into three blocks: monitoring, alarm and access control. In the security group, we shared a lot of things about video surveillance, so today we will talk about alarm system. Our common security alarm system is mainly divided into wired and wireless. Most of the home alarm is wireless, because it is easy to install, no cable constraints, and does not destroy the overall environmental style of the home, so it is deeply liked by home users. Smart home security products are mainly based on wireless alarm and monitoring. But in the business environment, or systems engineering, the disadvantage of wireless appears. Therefore, wired burglar alarms are trusted by most engineers because of their stability and affordable price, but for personnel who are generally not professionals, it seems that it is a little difficult to connect wired detectors and burglar alarm hosts. We know that the main components of an anti-theft alarm system are composed of three parts: alarm motherboard, front-end detector and alarm transmission device (network alarm communication and on-site sound and light alarm). The front-end detector includes passive infrared, infrared plus microwave double detection, infrared through-beam, infrared guardrail, manual alarm, fire house detection, glass breakage, etc., which are suitable for different environments according to different functions. The front-end detector is the sensor of the alarm system, and the detection of the external alarm situation by the alarm system is completed through the front-end detector. As far as the connection and signal transmission between the front-end detector and the alarm host are concerned, in the final analysis, it is a switching signal transmission and reception process. The so-called switching signal is the process of opening and shorting an electrical circuit. Taking the conventional alarm system generally adopts normally closed working mode as an example, when the system is powered on normally, if the detector is powered off or triggered by the alarm, the relay in the detector sends out an action, the contact changes from the closed state to the disconnected state, when the alarm host detects this change in the corresponding defense zone port, it will take corresponding reactions according to the current state settings (including ignorance, alarm, signal output, etc.). In fact, the working principle of alarm host and alarm detector is very simple, but why many people in practice cannot be properly configured and used, in fact, some key basic knowledge is not well understood. Today, let’s talk to you about the wired defense zone and the connection between the wired detector and the alarm system. The basics can’t be less: what is end-of-wire resistance. End-of-line resistance (or end-of-line resistance) English EOL Resistor: End-of-line resistance (EOL, End of Line) circuit, the circuit is characterized by the loop terminal access resistance, the short circuit to the ground will trigger the circuit contact action, such as when the system is armed, the loop is broken or short circuit will trigger an alarm. The scientific name is end-of-line resistance, the specific specifications of end-of-line resistance different brands and models of alarm hosts have their own specifications, the resistance of each manufacturer is different, commonly used are 1KΩ, 2.2KΩ, 4.7KΩ, 5.6KΩ, 6.8KΩ, installed on various detectors, that is, the end of the line. With normally closed circuit, the EOL is connected in series to the circuit, with normally open circuit, the EOL is connected in parallel to the circuit, when alarming, the host will detect the change of resistance value, in other words, as long as the resistance output to the host is not the nominal resistance value (such as 4.7KΩ), the alarm will be alarmed. The task is to prevent vandalism, and you will also call the police if you cut the line or short circuit. To put it very clearly, there are two ways of end-of-line resistance: one in series and one in parallel. Normally closed loop (NC): normal short circuit, open circuit alarm. The disadvantage of this circuit formation is that if someone shorts the line, the probe loses its effect. The alarm host cannot identify the human short circuit. Normally open loop (NO): short circuit alarm, open circuit normal. The disadvantage of this circuit formation is that if someone breaks the line (cuts the signal line), the probe loses its effect. The alarm host cannot identify the section that is human. Line tail resistance EOL: normal short circuit, open circuit alarm. The advantage of this circuit formation is: if someone breaks the loop line (short circuit back circuit), the alarm host can alarm. Short circuit alarm, open circuit fault, resistance value (such as 4.7KΩ) is normal. The advantage of this circuit form is: different reactions to short circuits and open circuits, especially suitable for smoke detectors and emergency buttons, if it is a mouse bite or tears off due to helping something, the alarm host thinks that the circuit is faulty. Therefore, in practical applications, without passing the detection of end-of-line resistance, but simply connecting normally closed and normally open circuits, there are great alarm safety risks. Meaning of alarm host AUX, Z-, Z+: Unlike wireless detectors, which use battery power, wired detectors are usually powered by DC voltage, and the AUX of the alarm host provides power to the wired detector at the detector power output. Usually the voltage value output of the alarm host AUX is DC12V, DC14V. Z- represents the negative pole of the wired defense zone, generally Z-ground (GND), Z+ represents the positive pole of the wired defense zone, usually with a certain voltage. Common connections for alarm detectors: The lead port of the front-end detector generally has six: power supply + (generally marked as +), power supply – (generally marked as -), alarm signal normally closed output (generally marked as NC or ALARM), alarm signal common end (generally marked as C or ALARM) and two disassembly signal output ports (generally marked as T or TAMPER), we can achieve different anti-dismantling functions and alarm effects through different line wiring and resistance mating. 1. No tamper-proof wiring Do not enable the detector anti-dismantling function, the alarm system can not sense whether the detector is damaged, this way of wiring in the alarm host does not set a separate anti-dismantling zone or anti-dismantling setting, the detector’s signal cable only needs four cores. Its wiring method is the simplest and most reliable, but it is less secure. In this wiring method, the alarm host can only sense whether the detector is triggered by the alarm situation, but cannot detect other things such as the box cover is opened and the line is damaged (when the line is short-circuited, the alarm system still thinks that the detector is working normally, and when the line is cut or the detector loses power, the alarm system believes that the alarm situation has occurred). 2. Separate anti-dismantling zone wiring The detector tampering port signal is specially connected to the alarm host dedicated to the anti-dismantling area, the wiring of this method is reliable and simple, and the anti-dismantling zone is separately programmed by the alarm host to achieve the equipment and line dismantling. Because additional lines are required to transmit tamper-proof signals, the cable selection of the detector must be more than six cores. In this wiring method, when the detector box cover is opened, the line is cut or the detector loses power, regardless of whether the alarm system is in the arming state, the anti-dismantling zone corresponding to the alarm host will be triggered to issue an alarm that the equipment is disassembled, but this method will not trigger the alarm when the detector tamper-proof interface or the line is short-circuited, which has certain limitations. 3. Single-wire end-of-line resistance wiring This wiring method has the basic equipment tamper-proof identification, and there is no need to set up a separate anti-dismantling zone in the alarm host, and the signal cable of the detector only needs four cores, and only the corresponding defense zone of the detector needs to be set as a single-line terminal defense zone. In this wiring method, the alarm host judges what kind of alarm situation occurs by the different resistance values output to different states of the detector signal line. 4. Resistance at the end of two wires This wiring method has the strongest equipment tamper-proof identification, and there is no need to set up a separate anti-dismantling zone in the alarm host, and the signal cable of the detector only needs four cores, and only the corresponding defense zone of the detector needs to be set as a two-wire terminal resistance zone. In this wiring method, the alarm host judges what kind of alarm situation occurs by the different resistance values output to different states of the detector signal line.

Installing active infrared beams detector is harder than installing passive infrared detector. The beams detector is installed at outdoor open space. It is always fixed on pillar or on wall. We should firstly confirm the protection line and draw the installing place on drawing. Then we mark the accurate installing point on fixing object such as wall or pillar by level instrument or other tools. Installing ways: 1. Installing the beams on pillar: there are some types of pillars such as pipe and square columns. The shapes are “1” shape, “z” shape or “L” shape. We should choose the correct type of pillar according to installing building feature and security protection requirement. The pillar should be fixed on ground or other objects strongly and without moving or shaking. It is important to ensure the beams detector installing and working properly. 2. Installing the beams on wall: the infrared beams can be installed on wall or fence, windows directly. The Optical lens of the detector has automatic up and down adjustment of 20 degree. Use fixing bracket to install the infrared beams on surface of wall or frame of windows. Principles of installing infrared beams detectors: Detectors installed on passageway: It is used to stop illegal passing and avoid false alarm caused by pet or small animals. So, the beams should be installed more than 50 cm (from the infrared beams hole) over the ground. The beams blocking response speed should be set at fast rate. Detectors installed on parapet wall: It is used to stop illegal climbing over the parapet wall. The beam can be installed over the top of the parapet wall or over the side of the parapet wall. It should be installed more than 25 cm (from the infrared beams hole) over the top of the parapet wall to avoid false alarm caused by bird or cat etc. animals. And the distance should be less than 30 cm between the beams hole and the wall inside part. When it is installed at side part of the parapet wall, it should be installed at outside part of the wall and near the top part. The installation way should be chosen according to protection requirement and building features. 4 beams infrared detector performed better than 3 beams to avoid false alarm.

Entry driveway alert is necessary for flat house families safety. Even if you live in wealthy and civilized country, there is still theft and burglary. Maybe the unbalanced society is the cause for it. However, try the best to prevent crime and keep safety is the best way and only way we can do. How to set up driveway alarm systems? The system is a set of wireless driveway sensors, solar-powered photoelectric beams sensor is the typical one, and alert siren strobe or wireless receiver. How does the driveway alert system work? When the car or someone pass through the driveway, the alert system will trigger alarm with sound and light outdoor on the wall and inside. It can be used as reminder of home owner back if it is necessary. Without getting near the house, entry action is known as alert or warning. How is it easy and reliable to use the wireless solar-powered photoelectric beams driveway alert system? No false alarm from birds, lizards, winds or fallen leaves. No any wiring is needed for power or for signal transmitting. There are two packages of driveway alert security system. One package is one pair beams sensor with outdoor solar-powered siren strobe. Another package is one pair beams sensor with indoor wireless receiver. https://www.vedard.com/blog

Passive infrared detector PIR is a type of weak signal detection equipment. There are some notices for attention when install it. For example, the installing height and sensitivity are two key points for attention. There are three steps to prepare and install a PIR detector. Step 1: Well understand the performance characteristics of the PIR detector. Step 2: Correctly determine the location for PIR detector installation. Step 3: Carefully adjust and debug the infrared detector. how to install PIR Below is the details for attention. A. Installing location: 1. Determine the correct installing height and angle according to PIR installing instruction manual and using requirement, environment. The protection area, sensitivity and pet immunity effectiveness is different with different installing height. Find out the entrance and exit of the building and intrusion routine, install the detectors at places to cover the areas. 2.Do not install the PIR detector facing glass doors and windows. PIR detector can anti interference of white light but not 100%. And outdoor passing people and vehicle may cause false alarm. PIR and MW double technology detector can be installed at this place without interference. 3. Do not install the PIR detector facing cold and hot air outlets or cold and heat sources. PIR detector senses object’s temperature change and triggers alarm. So the air flowing from cold or heat outlet may cause false alarm. If you have to install the detector at these places, you can choose PIR and MW double technology detector. 4. Do not install the PIR detector facing a swinging object. A swing object may cause false alarm by Microwave detector as well. Correctly install a PIR B: Detector choosing and debugging 1.Correct choosing of detector. There are various types of PIR detector. They are wide angle PIR or curtain PIR with 6m to 60m detection distance, infrared sensor or Microwave sensor, wall mounted or ceiling mounted. It should be correctly chosen according to protection space, intrusion routine characteristics, environment features. 2.Debugging Debugging is absolutely necessary work after installing of motion sensor. There are two ways for debugging. One way is walking test. The test person walks in the protected area with S routine to check the protected area. The microwave sensor sensitivity and PIR sensor sensitivity should be adjusted separately. Sometimes the sensitivity should be adjusted again in different season. Microwave has penetrability and the sensitivity can not be set too high. Another way is using instrument to measure. Some detector has noise voltage output interface. Using a multiple meter to measure the noise voltage and adjust the sensitivity.

Burglar Alarm System Installation is more complicated than CCTV security cameras’ installation. Especially for hard-wired burglar security detectors’ installation, there are some notes should be attended. 1. Select installation bracket Some security system installers maybe ignore the effect of brackets. Actually, the bracket can help accurately adjust the probe to guard against detection area. It largely saves time and cost of security system adjustment and future maintenance. But when the detector is installed between two sides of the wall with 90 degree, the bracket can be left out. 2. Pipeline laying We found potential dangers on pipeline laying in some burglar alarm system construction projects. The potential dangers we are talking here are not fire dangers but sabotage dangers. Using PVC cable sheath or even bared cable, not enough pipeline installation height etc. are the potential dangers for sabotage. Some security burglar alarm system installers may think this does not matter cause there is tamper-resistance function with the alarm master controller and it can make alarm when the detector is sabotaged. But the sabotage can greatly affect the security system working efficiency and even cause the security system shutdown for repair. It needs much time and energy for the security system engineers checking and troubleshooting. If the problem can not be solved in short time, the system may not been armed and not work. Then what cable sheath should be used? Galvanized welded steel pipe with metal hose and fully sealed metal wiring box is the better equipment for cable wiring outdoor. 3. Hidden pipeline In the actual installation process, especially for some new buildings, the pipeline should be buried. That will ensure concealment of transmission path and avoid sabotage. At the same time the buried pipeline should be convenient and flexible to access to the main bridge. In order to add wiring in the future using the threading apparatus, it is better to pre-set a small diameter steel cable in each pipeline. security system project Install hard-wired burglar alarm system 4. Redundancy of feeder cable length When a probe is installed and fixed, the next thing to do is to connect the wire probe. How to accurately calculate the cable length reserved? If the feeder cable length is too short, it is difficult to adjust the probe angle. If the feeder cable length is too long, the probe case will be hard to cover and have to put the extra cable outside. But the exposed cable will cause detector security risks. So, we should firstly fix and adjust the detector target to protection area, then measure the needed wiring cable and cut off the extra cable. 5. Connect tamper-resistant switch When connect the detector especially intrusion detector to the security system, the tamper-resistant switch should be connected as well. If tamper-resistant switch is not connected to the system, the theft can destroy the detector at disarm period and without notice. 6 wire cable such as RVV6*0.5 6 core cable is used to connect the detector. Two wires are used for power supply connection. Two wires are used for alarm contact connection. Two wires are used for tamper-resistant switch connection. The tamper-resistant switch wiring should be connected to 24 hours defense zone. So, it can ensure the security of the detector and system against sabotage. 6. Early Determination of installation location The detector installation location should be determined early before system installation cause it is hard to move after installation. The detector installation location should be determined according to protection area and environment. If the installation location is not proper, the false alarm and missing alarm events may happen. Conclusion: Burglar Alarm Systems are popularly installed for security protection of home, business and industry. But if burglar alarm system is not installed correctly, the security system may not work properly. So, correctly installed burglar alarm system can ensure the security system working effect without repair and trouble. Every security system installer should know the installation principle and not only install the detector, alarm panel according to the products manual.

It is easy to build up security service center based on HB security equipment. HB company has developed two sets of specialized cluster servers which provides uninterrupted and stable transfer service for mobile apps without fixed IP Internet access or for the security service. Meanwhile, it pre-installs the video private cloud service, which provides strong support for video linkage pop-up screen. Security service can build up their own cluster server. Server configuration requirements: CPU requirement: Intel 4 core more than 4 threads, 3-stage buffer more than 3M, above 3GHz processor; The main board has 4 channels of memory, which can support more than 32g of memory and more than gigabytes of network card; Memory 16G, main frequency ddr3 2400 or above; Over 1T hard disk; Network addressing service, video private cloud service, mobile APP service, etc For small or medium security service company, no server is available at initial time. HB companyh will provide PC operated CMS. Just install it and can manage the security alarm information on PC. Features of HB security service center. 1. Four uploading and downloading channels to ensure the stable operation of the system. The first channel is a direct connection from the client host to the alarm center with fixed IP network. It links to the destination address without any transfer. The second channel is to connect to the security alarm center after the transfer from the client host to the main server. Thes main server can be either a public server hosted by our company or a server built by the security service center. When the system detects the abnormality of the first direct connection through the main channel, it will automatically switch to this channel. The third channel is to connect to the security service center after being transferred from the client host to the standby server. At present, our company has built two sets of identical servers, which will automatically switch to the channel when the system detects that both the direct connection channel and the transit main channel are abnormal. The fourth channel is that the GSM SMS alarm center connects the SMS cat module through the serial port. When the system detects that all network channels are abnormal, it will automatically start the SMS channel to receive the alarm information. 2. The platform is designed with alarm networking as the main body and video linkage as the auxiliary. The alarm system can not only realize the synchronous popup of baidu map, point location distribution map, video monitoring three screen display, but also support the user’s mobile APP, local, security center and other multi-level synchronous alarm. 3. Open, standard platform, stronger compatibility. The security system platform is designed based on ADEMCO network protocol and can be compatible with all other brands alarm device. 4. The setup of private server ensures the smooth and stable operation of the system. 5. The using of solar power wireless detectors, beams largely saved the security service maintenance cost. 6. Support multi-level synchronous alarm, various kinds of screen split display, more intuitive User can use mobile phone app to receive alarm and view the video, alarm point map and video monitoring can be poped up at local alarm center, pop up baidu map, point map and video monitoring map, split screen displayed on security service center.

There are two types of smoke alarm according to different types of sensors. They are ion smoke alarm and photoelectric smoke alarm. The ion smoke detector has an ionization chamber. The intensity of americium 241(Am241)used in the ionization chamber is about 0.8 u Curie, which is in equilibrium under normal conditions. However, if smoke enters into the ionization chamber, the equilibrium relationship will be destroyed, and an alarm will be given out when the smoke concentration reaches a defined value. There is an optical chamber in the photoelectric smoke detector and an infrared counter tube is installed. When there is no smoke, the infrared receiving tube can not receive the infrared light from the infrared transmitting tube. However, if there is smoke entering into the optical chamber, the smoke is refracted and reflected, the receiving tube will receive the red light. The intelligent alarm circuit judges whether the smoke density is exceeded. If the smoke density value is exceeded, it will give out alarm. What is the difference of these two types smoke alarm? The ion smoke detector is more sensitive to small smoke particles. In open fire (such as burning newspaper) and fast burning fire, there are more small particles in the air, and the ion smoke alarm will make alarm first than the photoelectric alarm. Photoelectric smoke detector is sensitive to larger smoke particles. When smoldering (such as cigarette igniting sofa), there are more larger smoke particles in the air. At this time, photoelectric smoke detector will make alarm first than ion smoke alarm. The ion detector has radiation, which will cause bad effects on human health, while the photoelectric detector will not have any impact on health, so photoelectric smoke alarm is always used for home security. https://vedard.com/blog/what-type-smoke-alarm-is-better/

Introduction Network alarm system is a variety of transmission channels to transmit protection areas’ information to security service center quickly and accurately, so that the police officers can dispose all kinds of unexpected events in time. So, transmission technology is important part of the network alarm system.

1、How many zones can connect to panel? For the moment ,we have 9 sets of host unit , the least one support 4 defense zones, the most one can be up to 1000 zones. If you wanna more zones, we can make according to your requirement. 2、Are your devices working at low temperature (-2 to 15 degrees) in winter time, (17 to 55 degrees) during summer time? Our detector supported working temperature range :-30C~70C. We have been sold this product more than 10 years, we have long-term partner in bad weather countries such as Russia、Africa. 3、Are these solar alarms compatible with ademco alarm systems? We total have 9 sets of alarm host: Ademco available:HB-BJQ560-A; HB-BJQ560-B; HB-2020C;HB-3030C;HB-G250. Ademco unavailable: HB-MFR;HB-2020A;HB-3030A;HB-G10 4、what distances can products achieve? The infrared detection distance for infrared beam is 100 meter, for infrared grating is 10 meter and for infrared light wall is 20-50 meter. The wireless transmission distance is 800-1000 meter. It meets FCC and CE certificate. 5、Do you need a tool to calibrate the transmitter and receiver beams? Laser pointer is used for calibration of detection distance exceed 50 meter. HB-T001Q3+ has built-in calibrator already. Infrared grating series: no need laser pointer, because the infrared distance is only 10m , you just need make sure the grating be installed in the same horizontal and vertical plane. Garden Light&Detector series:no need laser pointer, because the infrared distance is only 20m-50m , you just need make sure the Detector be installed in the same horizontal and vertical plane. Photoelectric beam sensor series: Infrared distance is 100m. You need to use the laser pointer. HB-T001Q3+ is with built-in LCD calibrator and not need extra laser pointer. Remarks :After installation, verify the sensors whether be well mounted.(watch the video and the manuals). 6、I need to know how to match the beams with each type of system and how they work? Firstly: turn on the sensors Secondly: set the alarm host into coding status Thirdly: trigger the sensor, so the alarm host can remember the sensor We have 9 types hosts working as wireless receiver. The steps of programming is different. Please read the manual and watch video for guidance. 7、What is the lifespan of the standby battery? The lifespan of the battery is more than 10 years.Firstly,Our battery is LFP battery ,its cycle recharge time is 2000 times.Secondly,the capacity of the battery is 500mAh, while standby current consume only 0.5mAh,the sensors can normally work more than 15days without solar charging. So we can got: 2000times (LFP battery cycle recharge time)X15days(standby time)=30000days(about 82 years),deduct any other factors,10 years is available. 8、Please tell me more about perimeter defense. If total fence length to protect is 2800 meters, how many pairs beams are needed? The working principle of our sensors is the same as wired sensor. One pair beams is needed for every 100 meter. If there is corner or wall is not straight, then add more beams. Remarks: If wireless distance between sensor and host unit exceed 3km,Signal Repeater (HB-ZFQ) is suggested, one Repeater can enlarge wireless distance 3km,currently we support 4 grades, that’s say we can use 4 ZFQ without signal interference, and wireless distance:4-levels transmission X1km/grade=4000m.so more larger defense area is realized. 9、Does the beam system work at days without sunshine, like UK climate? Firstly, Our solar panel is made of amorphous material. It can convert light to electric even in cloudy or rainy days,without any direct sunshine. While at rainy days ,the solar panel can generate 2mA current to the battery .Wireless solar beams linkage Secondly, the static power of our sensors is only 1% of traditional wired sensor(static power:0.5mA).Besides:the sensors have high-capacity LFP battery inside,can keep the sensors working much more than 15 days without charging. 10、What is the extension of the wireless signal of the signal repeater HB-ZFQ? Without any obstruction, one transponder can enlarge 3KM wireless distance. Currently we support 4 grades transmission, that’s say we can use 4 ZFQ without signal interference. wireless distance:4 grades transmission X3km/grade=12KM. 11、Is there a signal repeater HB-ZFQ with solar panel? For the moment, we don’t have solar wireless signal repeater.If that’s necessary to your project, we’ll provide a solar powered device for the repeater. 12、Also please confirm if the wireless link is one way or duplex? Our wireless link is one way, that is to say sensors transmit wireless signal to host , but host cant send signal to control the sensors. While our sensors will self-check every 2 minutes, if any problem (e.g. low-battery、invalid、light interference etc.) ,Sensors will immediately report to host. 13、What is the mechanism your system uses in order to detect stealing of sensors or jammer the signal in order to tamper the system? Firstly, the working principle of our sensors is Active infrared detecting, so if any terminal is moved or damaged, sensors will report to host at once. Same time,host will indicate abnormity (e.g. alarming ,invalid , light interference). Secondly ,the wireless transmission technology we made is FSK + FHSS technology,it has strong ability to anti-interference.( e.g. once sensor was Triggered), it will send 3 signals to host (3 different frequency points),and host can receive these signals independently. This anti-interference technology makes our products more competitive in same line. 14、Do they check status with the sensors , like a test signal? How often? Our solar sensors will self-check every 2 minutes, if any problem (e.g. low-battery、invalid、 light interference etc.) ,Sensors will immediately report to host. 15、Do your sensors have anti-masking features? The sensors adopt FSK + FHSS technology，it has strong ability to anti-interference. i.e. once sensor was triggered, it will send 3 signals to host(3 different frequency points),and host can receive these signals independently. This anti-interference technology makes our products more competitive in same line. 16、Do the sensors come with the brackets? Brackets for sensors are not included in package. If necessary, we’ll configure brackets to your order,but it’s better to purchase in your location, common size is OK. 17、What frequency is this transmitting on and do you have GSM notification by text to cellphones for your products?Our frequency 433MHz (FSK+FHSS technology) once sensor was triggered, it will send 3 signals to host(3 different frequency points),and host can receive these signal independently. This anti-interference technology makes our products more competitive in same line. Host support GSM is :HB-BJQ-560B,HB-G10. 18、Our main concern is how to communicate your system to an Out sourced Monitoring Service? Solution 1:using the switch outputs to linkage the monitoring service. Sensors ’ Wireless Signal— � host/adapter—- � switch outputs interface– � control surveillance device (DVR) HB-MFR, support 4 switch outputs; HB-ZJQ-3,support 8 switch outputs If you wanna not only DVR ,but also need LED lights indicate detailed sensor’s zones and locations(as electric map), suggest : HB-G250(engineering host )+HB-LD(linkage module),HB-LD includes : 32 switch outputs and 120 pieces LED lights Solution 2: using the internet to linkage the monitoring service. Network module–�surveillance device (suitable for more range project)HB-G250(engineer host) and HB-WT(network module) is a Unit ,and we offer SDK data. 19、the wireless is APPROVED for Canada？ What frequency is it? And how far will it work? Our products was certificated by FCC and CE, and we have many regular Canadian customers, its standard for Canadian frequency. The sensors adopt 433MHz(FSK + FHSS) transmission technology，that to say once sensor was triggered ,it will send three signals(different frequency points) to host. and host can receive these signals independently. This anti-interference technology makes our products more competitive in same line. 20、Are these just sensors or do they act like an alarm system that can report to A central monitoring station for supervision. We provide the burglar alarm system; Firstly, we total have 9 sets of alarm host: Ademco available:HB-BJQ560-A; HB-BJQ560-B; HB-2020C;HB-3030C;HB-G250. Ademco unavailable: HB-MFR;HB-2020A;HB-3030A;HB-G10 Secondly, our sensor will self-check every 2 minutes, if any problem (e.g. low-battery、invalid、 light interference etc.) ,Sensor will immediately report to host.So that user can make solution at first time. Thirdly, We have other accessories to realize other functions. A、433MHz Signal Repeater (HB-ZFQ) B、433MHz wireless signal to switch-out adapter(HB-ZJQ-3&HB-MFR) C、linkage module Remarks: If wireless distance between sensor and host unit exceed 3km,Signal Repeater (HB-ZFQ) is suggested, one Repeater can enlarge wireless distance 3km,currently we support 4 grades, that’ s say we can use 4 ZFQ without signal interference, and wireless distance:4-levels transmission X1km/grade=4000m.so more larger defense area is realized. 21、But I’m wondering if the sensibility could be adjusted? Most of our sensors’ sensitivity can be adjusted by customers. Kindly attention that unusual sensitivity will result in false alarm, such as free falling object. Adjust sensors’ sensitivity as follows: PIR series:there is a Jumper inside–30S/120S(Item No.HB-T201;HB-T205) Infrared detector series(Items those can be hand-made): Regular sensitivity alarming time:200ms (HB-T001S4;HB-T001S8;HB-T001Q3+;HB-T001Q4;HB-T001Q6;HB-T001Q8) Regular sensitivity alarming time:100ms (HB-T002A8;HB-T002S8;HB-T002S8-D) Ways to adjust sensibility: restart the sensors(both transmitter and receiver)–long time press the receiver’s on/off button 10 seconds–after one beep–press the receiver’s on/off button 5 times(sensitivity time-200ms);press the receiver ’ s on/off button 6 times(sensitivity time–100ms)—OK Ways to rematch the infrared light of the sensors: restart the sensors(both transmitter and receiver)–long time press the receiver’s on/off button 10 seconds–after one beep–press the receiver’s on/off button 4 times—OK Adjust only by factory: HB-T001Q2;HB-T001Q3 22、What happens if a bee, or a bird passes through the IR-fence?Bee or bird flying cant trigger the sensor? Bee of Bird flying will not trigger the sensors Firstly, if obstacle freely falls and pass through defense area, sensors will not alarm. Secondly, if 3 infrared holes can’t completely blocked by material, sensors will not alarm. So, compared with other sensors,our products more effective in reducing false alarm. 23、The IR beams works at 433 MHz?, Could work with other alarms also at 433MHz, or only with your alarm host? The sensors adopt 433MHz (FSK+FHSS technology) once sensor was triggered, it will send 3 signals to host (3 different frequency points),and host can receive these signals independently. This anti-interference technology makes our products more competitive in same line. Moreover, the code modulation of our detectors is private protocol, so the detectors are hardly directly match up with third-party 433Mhz alarm host.But we have two ways to contact with third party host. Firstly ,we have switch outputs adapter to convert wireless signal to wired signal to third-party host(on condition that third-party host has wired zones) Secondly, Send detailed technical parameters of your host to us,we’ll adjust our sensors and pair with your host ,need to mention that will reduce wireless distance and anti-interference function.

Infrared detector is popular motion sensor. The PIR is used for security protection of bed rooms, living room, balcony etc. It is installed with bracket for angle adjustment. The detection area may be horizontal 110 degree, thickness 65 degree of fan-shaped area. Can you install the PIR according to the instruction manual? Below we will make clearer steps for guidance. Step1. Using impact drill to make two holes on the wall according to PIR bracket fixing hole. Then fix PIR bracket with screws (included in the PIR package) If there is no impact drill, using cement nail to fix the bracket on the wall. Step2. Insert the PIR body to the universal bracket. The PIR level angle and vertical angle can be adjusted for best detection. It is better to install PIR in the corner of wall to get best protection area. Select installation location, installation height according to PIR instruction manual. Below is the illustration of installation ways and effect. magnetic contact is another essential component of home security. Door contact includes two parts: magnetic switch and emitter. When these two parts are separated by about 1cm, the emitter will send alarm signal to siren strobe or alarm control panel. Magnetic contact can be used for alarm of door windows, fence or other protected objects. The emitter should be installed on fixed object such as the door frame. The magnetic switch should be installed on moving object such as door. If the door and the door frame is not at the same plane, you can use a small piece of wood to block up the low side. There are metal door contact, wood door contact and rolling door contact. Please select corresponding door contact for the door security protection. You can use double faced adhesive tape to fix the door contact or use screw to fix the door contact. It is better to use screw fix it. The alarm system installing manual will guide how to enroll the PIR, door contact to the alarm control panel. You should read the manual carefully and follow it.

Solar powered photoelectric beam sensor with solar lamp makes up new product – Solar alarm lamp. The solar alarm lamp can be used for courtyard, garden, golf course, villa house, swimming pool. At night, the LED lamp will light up the garden, golf course etc. At daytime, it lights off automatically. Meanwhile, the built-in intrusion detection photoelectric beams keep creating an invisible light wall to block invasion all the time. Unmanned Small Aircraft intrusion will be detected as well. What will it do after intrusion is detected? The wireless alarm receiver control panel (another product of the security system connected to the sensor) will make sound and flash alarm and send alarm message via phone call, SMS text, app pop up notification. You can preset police center phone number for emergency call if you are allowed. The alarm message and security system arm/disarm status will be recorded on app. How does it look like? The two parts are as below. There are two types solar alarm lamp. one is single direction alarm lamp, another is double directions alarm lamp. What is the difference? Single direction alarm lamp creates one way invisible light wall only. For one pair beam sensor, invisible light wall only created between transmitter and receiver terminals. But with double directions alarm lamp, extended opposite invisible light wall is created as well. See working effect as below pictures. How to install the garden alarm lamp? From below picture, we can know the solar alarm lamp consists of 3 parts, lamp, pedestal， pole with beams. So, you just need to put these three parts together according to manual. What is the limitation for the solar alarm lamp? The maximum trigger alarm times is 200 in 24 hours. The service life (for battery) is 5-8 years. The infrared detection distance(installing distance between transmitter terminal and receiver terminal) is 50m. The wireless RF transmission distance is 500-800m. It should be used with same brand wireless alarm control panel for alarm information report and system inspection status report.

Natural gas, LPG is used for home cooking, heating. But the gas is with dangers if it is not used properly. So, people should know how to use the gas source correctly. A gas detector is not enough for home gas security. A connected solenoid valve is better for gas source leakage shut off. What should we do if gas leakage is detected? The fire fighting person said:”When we are at gas leakage spot, we even dare not kick the door or knock, smash with a metal tool. Because that may produce spark and detonate gas.” We should remember what we must not do at gas leakage spot. gas leakage control 1.No fire is allowed, no smoking, no lighter. Otherwise the leakage gas make be detonated. 2.No turning on/off of house appliance. Because that may produce spark and detonate gas. 3.Do not dial telephone at gas leakage spot. Because that may produce spark and detonate gas. What should we do then when we find gas leakage? 1.Shut off gas source. Tighten the LPG bottle valve. Open the doors and windows for ventilation. Can use a broom to disperse gas leakage in air. 2.If the LPG bottle is with cracks, it should be gently moved to the outdoor ventilation place. 3.If large amount gas leakage is found, please leave the spot immediately. Cut off the power supply. Extinguish all fire. Go outdoor and call for help. 4.If gas leakage is found from neighbor home, please knock the door to notice it. Do not press the door bell.

Explosion proof products are required to be used in oil field, chemical industry factory, metallurgical industry environment. Harmful gas detector, sounder, siren strobe, beacon, fire alarm systems are used for these fields with explosion proof requirement. That is because there is explosive mixture in these environment. There are three types explosion proof products: intrinsically safe type, flameproof type, increased safety types. Explosion Proof zones: zone 0: Under normal circumstances, explosive gas mixture exists continuously or for a long time. zone 1: Potentially explosive gas mixtures may exist under normal conditions zone 2: Under normal circumstances explosive gas mixtures does not exist, only in abnormal situations, explosive gas mixtures may exist occasionally or in short-time. zone 10: Under normal circumstances, the mixture of explosive dust or combustible fiber and air may exist continuously, appear frequently or exist for a long time. zone 11: Explosive dust or mixtures of combustible fibres and air cannot occur, only occur in occasionally or for short periods in unusual circumstances. explosion proof gas detector, sounder beacon According to explosion gas species and Minimum detonation spark energy, the gas explosion is divided into 4 grade. explosion gas species According to explosion gas temperature, there are 6 groups. Check below of temperature groups and gas species. explosion gas temperature Explosion-proof certification mark According to factory or mine explosion media, the minimum sparking energy, the minimum sparking temperature and explosion gas existing time, there is classification of explosion proof certification mark. For example: ATEX form, E Ex iaIIC T4, E means Cenlecom certificate mark, Ex means explosion proof, ia means intrinsically safe type and can be installed at zone 0 area. IIC means it can be used at environment where IIC type gas exists. T4 means it meets T4 safety temperature group requirement. Dust and water proof grade: Explosion proof products have dust and water proof capacity as well. It is marked as IPXX. For example: IP65 means it has totally dust resistance capacity and can accept low pressure water jet from all angles. Vedard Security supplies explosion proof sounder, bell and lighting, siren strobe, smoke detector, heat detector, H2S detector explosion proof, beacon explosion proof, HC detector, manual call point explosion proof.

Alarm System is a security system consists of 3 parts alarm units. They are detectors, alarm control panel and CMS. We will share our working experience of alarm system troubleshooting categorized into 3 articles according to these 3 parts. 1. The alarm system does not alarm after system armed or forced armed and wired detector is triggered, why? Possible causes: wiring error such as wired detector is not connected with alarm control panel correctly, short-circuit or cut of wiring between wired detector and alarm control panel, low voltage of the detector or end line resistor is not wired or not correctly wired. Programming error such as zone attribute is not programmed or not correctly programmed. Solution: Check and confirm the wiring between wired detector and alarm control panel is good and end line resistor is wired correctly. Check the supplied detector voltage and confirm it is not less than 9V. Check the zone attribute is edited correctly. alarm system troubleshooting alarm control panel The alarm system does not alarm after system armed or forced armed and wireless detector is triggered, why? Possible causes: The detector battery voltage is low. The detector is not correctly learned to the alarm control panel. The detector is not programmed into the alarm system zone or zone attribute is not programmed correctly. The distance between wireless detector and alarm control panel exceeds rated distance. There is metal block between wireless detector and alarm control panel. Solutions: Change the battery and re-enroll the wireless detector to the alarm control panel, correctly programming the detector zone attribute. Shorten distance between wireless detector and alarm control panel. If there is metal block, please replace the wireless detector. 3. The alarm control panel can not receive remote signal and transferring signal, why? Possible causes: Power supply is not enough for remote controller or signal transceiver, the wireless remote or transceiver is not enrolled correctly into the alarm control panel. The distance between the remote or transceiver and the alarm control panel is too long. Alarm control panel can not decode the received signal. Solutions: Change remote battery and re-enroll the remote controller to the alarm control panel correctly. Shorten the distance between the remote control or the transceiver to the alarm control panel. If above solution does not work, there maybe problem of the wireless receive module of the alarm control panel and it should be return to factory for repair. 4. The alarm control panel makes false alarm, why? Possible causes: the detector fault or wrong installed. Solution: Check which zone triggers alarm and check the detector. 5. The alarm control panel makes sounds at normal work status. Possible causes: The alarm control panel can make sounds of alarm, fault alert, delay arm sound, alarm delay sound etc. Solution: Check and identify which sound the alarm control panel made then solve the problem according to the sound. If no alarm is triggered by detector and no instruction is made to the alarm control panel and it makes sound, then there maybe the alarm system error. 6. External siren is wired to the alarm control panel, but it does not sound when alarm control panel alarms. Possible cause: the Positive and negative wiring between siren and control panel is reverse or short-circuit. The siren voltage is low (less than 12V). The external siren is not programmed or correctly programmed to the alarm system. Solutions: Check and confirm the wiring is correct. Check and confirm there is 12V voltage output to the siren when the system alarms. If not, please program the system and turn on the external siren. If all above is ok but still no output from the external siren, please change a siren to test or change a alarm panel to test. 7. The alarm control panel does not dial alarm receiving number when it alarms. Possible causes: strong interference or short-circuit, cut of the telephone line. The receive phone number and communicate format, communicate grade is not programmed correctly to the alarm system. The telephone theft function is turned on. Solutions: Check and confirm the telephone line is good without strong interference, short-circuit and cut. If additional code is needed for outline dialing, please add it to the receive phone number when program it. 8. The alarm control panel does not dial CMS telephone number when it alarms Possible causes: strong interference or short-circuit, cut of the telephone line. CMS telephone number is not correctly programmed into the alarm system or user code is not enrolled or not correctly enrolled. Solution: Check and confirm the telephone line is good without short-circuit and cut. Check and confirm the CMS number including communicate format and grade and user code is programmed correctly. If all above is good and problem still exist, then please check the interference of the telephone line. CMS communication is data communicate and strong interference may lead to communication interruption. Conclusion: the updated new technology alarm control panel has voice, LCD menu, graphic prompt and low battery alert. So, alarm system troubleshooting is easy and the system has self-check maintenance program. So, alarm system is not coded and easy to operate than before.

On the fire regulation, there are some equipment should be automatically controlled by fire alarm control center. They are fire pump, smoke exhausting fan, fire proof door and fire curtain. The fire pump and smoke exhausting fan can not only be automatically controlled by fire alarm control center, but also be directly controlled manually at spot. Manual control buttons should be set on both sides of the fire rolling curtain on the evacuation channel. Why do these devices so important for fire fighting? These devices can extinguish early fire and prevent fire spreading. So, these devices should be automatically turned on or shut off immediately when fire occurs. Fire extinguish system controlling On the fire regulation, other devices are not required to be set as automatically controlling. For example, fire bell horn and fire broadcasting etc. should be manually triggered or linkage output triggered after confirmation or other signal is found. If fire bell and fire broadcasting goes off without confirmation, it may cause unnecessary fear for people if false alarm occurred. In the water extinguishing system, the fire hydrant system is controlled by the fire hydrant button, the start button on the control center linkage controller and the pump button on the pump control box of the pump room. Any button of these three ones is pressed, it will start the fire hydrant pump. It is manually controlled and not automatically controlled. There may have automatic and manual mark on the state switching switch of the control cabinet in the pump room. The automatic here means started by remote controlling and manual means started by local controlling. In an automatic sprinkler system, there are automatic and manual mark on the control cabinet of the sprinkler pump in the pump room. “Manual” means “on-site start” and “automatic” means manual start-up of the pump or pressure switch on the wet alarm valve of the control center. For the whole sprinkler system, “automatic” refers to the pressure switch start-up, and “manual” refers to the control center remote control start-up. Fire monitoring system For pipe network gas fire extinguishing system, the release of fire extinguishing gas must be confirmed by people on the scene. Automatic state of fire identification is equipment confirmation. Its general practice is two sets of detectors at the same time issued alarms, can be considered as a fire start signal. When the first set of detectors alarm, the personnel on duty should immediately rush to the scene to make a manual confirmation on the spot to decide whether to start the fixed fire extinguishing system. Although there are automatic and manual start-up modes in the design, manual start-up mode should be the main one when someone is on duty. So the fire control center panel only displays the manual automatic working state of the system. It monitors the system of alarm and injecting feedback signals at various stages, and controls other linkage devices such as fireproof doors and windows, air conditioning and fireproof valves. But it is not required to immediately start off the fire extinguishing system. This is to ensure the reliability and accuracy of the system.

A survey of housing safety said burglar alarm system is useless. A good lock and scheduled house lighting is more important for home security. Is that right? Will theft pass a well locked and light house without thinking it is occupied or empty? How can a burglar alarm system well prevent burglary and stop crime? Actually, there are many functions of burglar alarm system people doesn’t know and doesn’t use. Fox example, the linkage output function. When a burglar alarm system is triggered, it can trigger alarm siren strobe and camera recorder or house lighting. So, not timer lighting but scare lighting will be turned on to drive out the theft. You may do not need a good lock but you can install a door windows barrier to block the burglary before they come near the entrance. Of course, the sensor can turn on the light indoor or outdoor with linkage function of alarm system. The linkage function is a simple port built-in for easy connection with any equipment which need to be triggered. For example, the FOCUS security has this function named PGM output. The FOCUS PGM output can be programmed with some event for selection. They are alarm, password change, AC power fault, communication fault, arm, disarm. That means you can select the event to trigger siren strobe or other device. For example, you select AC power fault event, then if the AC power line is cut, it will trigger the device immediately. The selection will be made according to your alarm system installing and environment features. When a CCTV system is connected as the event following device, the defined security camera will make video record as crime evidence and help finding the criminal. A professional alarm system can well prevent burglary cause the burglary crime will be noted immediately and be recorded. It does not only scare the theft but also stop the crime by warning the theft with listen-in and intercom function. More over, it records the crime scene and punish the criminal if the crime is not stopped. How to well use the burglar alarm system? Read the alarm system instruction manual carefully and understand the functions. Then enable and set the functions according to your home security needs. Of course, planning and making a suitable home security solution is the first step. windows security equipment You can easy add more sensors detectors to your exist alarm system. For example, solar power wireless infrared beam sensor can be added for perimeter security. Smoke and CO detector can be added for home environment safety.

How to make home security solutions according to individual needs and budget? Below we will give an example to explain it. The house is with 3 bed rooms, 2 bath rooms, 1 kitchen room, 1 study room and 2 balcony. Home security solution according to budget The principle of making home security solution. 1.Plan and make external security firstly. In security alarm industry, it is perimeter security zones. The security protection areas are fence, wall, gate and house entrances including door, windows and balcony. The connection areas between the upper and lower floors, between house and neighbor’s house. 2.Then plan and make internal security. In security alarm industry, it is interior zones and fire zones. The security protection areas are aisle, hall, living room, kitchen room, bed room, bath room. 3.The alarm control panel installing principle: A.Install it at place with telephone interface and hide it. Do not install it near the door or where theft can easy find and destroy it. B.If the alarm control panel can not be installed at hidden place, then a PIR motion sensor should be installed to monitor the alarm control panel. C.It is best to install the siren strobe outdoor and far from the alarm control panel. D.If the siren strobe can not be installed outdoor, it is best to use wireless siren strobe and avoid theft finding the alarm control panel. Step 1: Define the protection range according to the house situation. From below drawing, we can know the most easy to be invaded place is two balconies, then is the out door. And kitchen room windows, study room windows cause these rooms are always vacant at night time and can be entrance of theft. Bath room, child room, main bed room are listed as protection areas with priority code. All protection areas are listed with priority code from 10 to 1 as below. Step 2: Define defense zones and defense way, equipment for each zone. After protection areas and zone is defined, the defense equipment quantity and types should be defined according to the community security environment and family environment, behavior. The above home security solution design for example, we can use different equipment for different level defense. The equipment can be added or deducted according to budget and needs. Home intrusion places and alarm type 1.Simple type installation: With lowest budget and good security environment, we make simple type installation. Only gate No.7, balconies No.9 and No.10, kitchen room No.6, study room No.5 are defensed. Wireless door magnetism contact is used for gate No.7, kitchen room No.6 and study room No.5. PIR motion sensor is used for living room and bedroom to against intrusion from two balconies No.9 and No.10. The alarm system used is 1pc PIR motion sensor, 3 pcs door or windows open contact, one set alarm control panel with 1 PIR, 1 door contact, 2 keypad, remote controller. The functions of the simple type alarm system. A.When the gate or kitchen room window, study room window is opened, (door or window is leaving more than 1 cm from the door frame or window frame) or someone is entering into living room or bedroom from the balcony, the alarm system will go off and siren strobe makes sounder and lighting for warning. B.Backup battery is built-in and can work for 8-16 hours at AC off time. C.PIR motion sensor is used for zone 9 living room and home arm can be set when someone is at home. So, the living room PIR will not trigger alarm when someone is at home. D.If no one is at home, away home arm should be set and intrusion is detected at living room, the alarm goes off. The cons: When magnetic contact is used for windows security, the windows can not be opened even at summer time. basic home security installation solution 2.Basic type installation: Use wireless door windows magnetic switch for all doors and windows. Use 1 PIR motion sensor for addition of living room security protection. The functions of the basic type alarm system. A.When the gate or kitchen room window, study room window, bathroom window, child room window is opened, (door or window is leaving more than 1 cm from the door frame or window frame) or someone is entering into living room or bedroom from the balcony, the alarm system will go off and siren strobe makes sounder and lighting for warning. B. Backup battery is built-in and can work for 8-16 hours at AC off time. C. PIR motion sensor is used for zone 9 living room and home arm can be set when someone is at home. So, the living room PIR will not trigger alarm when someone is at home. D. If no one is at home, away home arm should be set and intrusion is detected at living room, the alarm goes off. Cons: When magnetic contact is used for windows security, the windows can not be opened even at summer time. When someone is at home, home arm should be set. improved home security solution 3.Practical type installation: Cause the basic type alarm system using windows contact for windows protection and the windows can not be opened at arm status, the curtain PIR is used to replace windows contact. The curtain PIR is with direction recognition and alarm goes off if theft entering from outdoor. The alarm will not go off if home owners is walking at home. Cons: The balcony security protection is not enough. The theft can enter into balcony without alarm going off. It alarms until theft goes into the house. plan home security solution with guide 4.High grade type installation: Use infrared fence as balcony and windows intrusion prevention security equipment. The infrared fence is installed outdoor and can stop intrusion outdoor. Smoke detectors and gas leakage sensors are used as well for fire prevention. Solar power wireless infrared fence can be used. It is easy to install and there is wireless to wired transceiver for connection with any third party alarm control panel. Smoke alarm and gas alarm should be set as 24 hours zone and not controlled by arm disarm setting. Home security solution with perimeter security 5.Complete type installation: With infrared fence installed outdoor for windows and door entrance prevention. And add outdoor PIR detector as well at balcony to ensure the alarm going off when the theft is at balcony. Add wireless siren strobe for warning and neighbor notice. So, home is more secured.

The dangerous gas includes combustible gas such as methane, ethylene, hydrogen, natural gas, LPG etc. and toxic gas such as CO, H2S, H2 etc. The dangerous gas is easy produced at industry fields such as chemical factory, oil field and may lead to explosion. Dangerous gas leakage alarm device is needed to monitor and notify people of the dangers and automatically shut off gas or drive electric fan etc. The gas leakage alarm device should be installed correctly for its proper work. Below we will make notes of the alarm device installation. The alarm device can not be installed at place with strong magnetic such as high power electric engine, transformer around. It can not be installed at places where corrosive gases are present. The alarm device is instrument for safety with sound and light display, it should be installed at places where people can easy see and hear then eliminate the dangers in time. There is platinum, palladium and other rare metals on the surface of alarm device probe, it should be taken care of and avoid breaking the probe when installing the alarm device. The installation position of the indoor probe is different according to the density of the detected gas. When the detected gas density is less than the air density, the probe should be installed 30cm from the roof and downward. On the contrary, the probe should be installed from the ground 30cm and upward. When the probe is installed outdoor, the installation position is confirmed according to detected gas density same as indoor installation. But be noted the probe should be installed on the downwind side. Protective casing is needed for alarm circuit connection cable. It is best to add metal hose to the probe wiring. The probe should be with the same level of explosion-proof with the factory. Do not test the detector with high purity gas. After installation and test, be sure to install breathable waterproof cover to protect the probe from water. Industry gas leakage alarm device is high accuracy explosion-proof instrument. It always work with fire alarm control panel or other security system to respond to gas leakage and prevent disaster.

FC-7448 bus-line alarm system is meian tech FOCUS brand large business security, community security, commercial security system. It adopts new technology PC and security communication method. It is popularly used by security service. There are many optional accessories for system expansion. They are telephone line monitor module, RS232 interface module and micro- printer, monitored circuit input module, bus-type detectors. Below is the notice and guide to help wiring FC-7448 bus-line alarm system. It is best to wire all modules and detectors to alarm control panel with one bus-line cable. If it is not available, then it is best to have branch line longer than 300m. The wiring cable should keep distance from strong interference cables such as 220V AC power cable and fluorescent lamp etc. and avoid to wire in parallel with them. If the wiring cable length is more than 1.5km,then FC-7425 bus-line separator is needed. One FC-7425 can extend as long as 1.5km (RVV2*1.5mm cable is used). If more than one FC-7425 is used, then the extended distance depends on the cable used and the performance environment. Power supply: Generally centralized power supply is used, that is all devices or some nearest devices share a power supply. All devices should have enough working power supply, if not, then additional power supply device is needed. When multiple power supply devices are working together, then connect the ground of all the power supplies together and connect to the black end of alarm panel. Each power supply device positive terminal connects to its supplied devices. Connect all the wires’shield together and connect to power ground with one end only(no multiple ground). Connect all modules to bus-line. The module address DIP switch is binary, and any two module addresses can not be the same. Connect detectors to modules. After complete all wiring works, check the wiring of all the devices in turn to see if there is missed and misplaced wiring. Use multiple-meter to check whether or not there is short-circuit between all wiring. Ensure all wiring are correct and turn on the power. If there are multiple power supplies, remember to turn on alarm panel power supply at last. Customer support for installing security system at https://www.vedard.com/forum

It depends on your housing features and your security requirement. If your housing is open with many entrances and you want to protect outside property such as vehicle etc. you need security service with professional installation. The installation will include perimeter protection and using more complicated outdoor detectors. Otherwise, your housing is relatively closed and indoor secure ways are enough. Then DIY alarm is OK. DIY alarm installers always choose wireless detectors and wireless siren with LCD, Keypad alarm panel. We suggest installing alarm panel at hidden place such as niche and have wireless keypad at hand for alarm information query and emergency alarm trigger. Security Service installers can choose hardwired or bus zones available and wireless alarm systems. They will install perimeter protection beams, double technology detectors at problem places where are with more interference. From www.vedard.com/forum

Intruder detectors decide the reliability of the alarm systems. To avoid the interference, anti-detection of fault alarm and missing alarm, multiple techniques are used in detector designing. 1. Micro-wave sending time will be staggered when more one detector is operated synchronously. So, maximum 4 pcs MW & PIR detectors can be installed in one room. 2. PET immunity: The infrared signal detected will be stored and compared with human body signal and excluded pet movement alarm. 3. Two infrared sensors are used to detect motion. The signal detected will be stored in RAM and will be calculated by logical addition, then the result and original signal will be compared to judge whether or not it is true alarm. 4. Anti-detection design: When the detector is set at anti-detection mode, CPU will analyze the weak signal detected and if it found it is anti-detection, It will active the micro-wave sensor to detect, and logical calculate both signals to judge. 5. Auto temperature compensation design to avoid environment temperature change. 6. Two infrared sensors are built-in. Motion sensors detected are same polarity and RF, electric magnetism, static electricity interference are opposite polarity. So, it can anti interference. 7.Micro consumption current designed for long life battery usage. From www.vedard.com/forum

Flammable gas alarm is used at home, hotel, restaurant and chemistry industry, factory etc. It consists of detector and gas density indicator. It monitors the leakage of flammable gas and show density of flammable gas. When the flammable gas detector is installed, the monitored field is fixed. There are a few key notes to refer before installing. 1.Make sure the points of potential gas leakage and calculate leakage gas pressure, leakage volume at unit time and leakage direction. Mark A, B, C as leakage degree. 2.According to air flow at the spot, draw direction of leakage. 3. According to leakage gas density (heavier than air or lighter than air), and air flow trend, draw the 3D leakage flow drawing. 4. Set monitor point under the flow point made at leakage flow drawing. 5. We need to guess the leakage state whether it is slight leakage or spraying leakage. If it is slight leakage, we need to install the detector near it. Otherwise, we can install the detector a little far away. 6. It is suggested to have detector every 10-20m. 7. For spot with hydrogen leakage, we need to install detector over the leakage point. Regular inspection is required for the flammable gas alarm device.

Carbon monoxide poisoning can cause serious damage to the brain tissue. Even if cured, it may remain a sequela of central nerve injury. How to avoid carbon monoxide poisoning? We need to know at what situations the carbon monoxide may produced. Coal burning Coal burning is used for heating or cooking. If the coal is not completely burning, it will being producing amount of carbon monoxide. If the room is closed or unventilated, carbon monoxide poisoning occurs. Combustible gas water heatercarbon monoxide alarm Combustible gas is used for water heater for some homes. If the gas water heater is installed in bathroom and with door and window closed, the gathered carbon monoxide will cause poisoning. So, it is better not installing gas water heater in bathroom. Stay or sleep in vehicle with air conditioner turning on When the running speed of the vehicle engine is slow, the gasoline is not burning completely and will produce amount of carbon monoxide. The produced carbon monoxide will blow into the car through air conditioner. What symptoms are carbon monoxide poisoning? Slight headache, fatigue, dizziness, nausea is symptoms of mild carbon monoxide poisoning. Frontal headaches, flush on face, very red lips, much sweat, fast heart rate, restless and entering into coma. That is the symptoms of moderate poisoning. Dizziness, nausea and convulsions, unconsciousness, body temperature rising. That is the symptoms of severe carbon monoxide poisoning. What should we do if someone has carbon monoxide poisoning?Help CO poisoning patient Cause carbon monoxide poisoning will injure brain tissue and the poisoned person can not move or ask for help by himself. If carbon monoxide poisoned person is found, the helper should creep to the scene and open door and windows quickly. Move the poisoned person to a ventilated and warm place and keep him or her lying. For patients who are unconscious, the head may be tilted to one side to prevent the vomit from being sucked into the lungs causing suffocation. Call an ambulance and send the patient to a hospital with a hyperbaric oxygen tank. How to prevent carbon monoxide poisoning? For the resident who uses coal to keep warm, the chimney should be installed in the room where fireplace is in. Open door or windows when coal oven is used for cooking or heating. Do not install gas water heater in bathroom. It should be installed outdoor or near the windows of room neighbor bathroom. Do not sleep or stay in vehicle with door and windows closed. Should timely open window for ventilation when air conditioner is turning on for long distance driving. Install Carbon Monoxide AlarmCarbon monoxide detector CO Carbon Monoxide Alarm is a security detector for sensing CO and triggering sound and light alarm if the monitored carbon monoxide density reaches to set value. It can be easy installed with AC power supply or connected to home security system. Where should we install the carbon monoxide alarm? If your bedroom hallway is longer than 40 feet, install a CO alarm at both ends of the hallway. Install at least one CO alarm near or within each separate sleeping area. For added protection, install an additional CO alarm at least 20 feet (6 meters) away from the fireplace, furnance or fuel burning heat source. https://www.vedard.com/forum

When you start DIY Your home security, there are some terms of the alarm systems you should know. The home security system is designed smarter and intelligent. But at the same time, it showed too sophistical for home owners, end-users to DIY. 1. What is entry time & leaving time? Entry time: It is alarm delay time. Arm the system, and when it is triggered, it will send information out after the entry time set. That would enable people to disarm when miss trigger occurred. Leaving time: It is arm delay time. Arm the systems, and it will start to arm after leaving time set. That will enable people to leave home after house is armed. 2. What is at home arm/disarm and away home arm/disarm At home arm/disarm: You can set some defense zones into one group, and use remote controller to arm/disarm with one click to set all. For example, you can set 1st floor, outdoor detectors armed but 2nd floor disarmed when you are at home. Away home arm/disarm: You can set some defense zones into one group and use remote controller to arm/disarm with one click to set all. For example, you can set all floors armed when you are away home. 3. What is defense zones attribution? The zones attribution include: 1. zone disabled. The control panel will not accept any information from this zone. 2. Burglar zones. The zones will be arm/disarmed etc. controlled via master control panel. Alert information will be burglar alarm. 3. Medical help: The zones will not be arm/disarmed controlled via panel but 24 hours armed. Alarm information sent will be medical help alert. 4. Fire alarm zone: The zones will not be arm/disarm controlled via panel but 24 hours armed. Information sent will be fire alarm. 5. Emergency zones: The zones will not be arm/disarm controlled via alarm panel but 24 hours armed. Information sent will be emergency alarm. 6. Gas leakage zones: The zones will not be arm/disarm controlled via panel but 24 hours armed. Alert information sent will be gas leakage alarm. 7. Door bell zones: The zones will not be arm/disarmed controlled via panel. But only door bell sound will be sent on-site. It will not dial out. 4. Telephone attribution: Telephone attribution include: 1. Telephone disabled. The system will not dial this telephone when alarm. 2. Voice format: Voice information will be sent when alarm. 3. CID format: CID information will be sent when alarm. 4. Arm Center: Only dial when system is armed. 5. Disarm Center: Only dial when system is disarmed. 6. Low power: Only dial when panel is with low power or AC power off. 5. Setting dialing times: It is to set the maximum times of dialing when alarm information is not dealt with. If the user answered the call and disarmed the system, it will not dial any other telephones. If the user answered the call and did not disarm the system but other operation, it will not dial this telephone but dial other telephones. 6. Setting ringing times of remote controlling: You can set the ringing times to accept remote controlling such as arm/disarm, listening etc. via telephone or mobile. 7. Breaking into alert function: Breaking into alert means when telephone line is occupied by telephone extension, the system will break into dial alarm and recover then. 8. Smart defense zones: It is set to avoid false alarms. When the zones is set as smart zones, the system will not send alert immediately, but wait till other status occurs in preset time.

Smoke detector, gas detector, heat detector, CO detector and compound detectors are used in fire alarm system. But false alarm caused by these detectors also led to serious loss. The worst is, false alarm in return caused misunderstanding of fire alarm system and people stop using it. People will remove the battery and not install it again if false alarm occurs. People may ignore real fire alarm if false alarm ever occurred. It is impossible to completely eliminate false alarm. But we need to know the causes of false alarm and reduce the rate. The compulsory certification, ISO9001, ISO9002 standard implemented for products manufacture largely reduced false alarm rate. New technology analog fire alarm system, MCU processing detectors also reduced false alarm rate. But another main factor for false alarm of fire system is environment interference and misusing of the detectors. 7 causes for false alarm of fire alarm system are summarized as blow. 1.Non fire smoke but dust factors Reduce false alarm of fire alarm system A.Cooking oil fume. If the smoke detector is installed in kitchen and near the oven, the smoke detector especially the ionization detectors will make false alarm. So, smoke detector can not be installed in kitchen. Heat detector and gas sensor should be installed in kitchen. B.Smoking. For high sensitivity smoke detector, smoking may cause false alarm. So, the sensitivity should be adjusted according to environment or people should be noted without smoking at the place. C.Steam. Smoke detector installed in bathroom may cause false alarm by steam. So, install heat detector instead of smoke detector in bathroom. D.Dust. Smoke detector can not be installed at heavy dust circumstance. Insecticide. Aerosol insecticide and air freshener may cause false alarm. 2.Environmental factor A.Electromagnetic radiation. 7 causes for false alarm of fire alarm system B.Airflow. Airflow may interferes ionization detectors more than photoelectric detectors. C.Rapid temperature changes. The heat detector and compound detector can not be installed near the air conditioner or heater device outlet. 3.Quality of detectors A.Design quality of the detectors. Fault tolerance: the ability of system software to maintain normal operation under the action of known and unpredictable accidents. Tolerance: the ability to maintain the system performance unchanged when the parameters of the system hardware components are discrete. Environmental sensitivity: the ability of the system to maintain stable operation in the mechanical, climatic and electromagnetic environment which is stipulated in the national standards and is potentially used in practice. B. Manufacture quality of the detectors. Automatic manufacturing process, ISO processing standard implement and certification test largely increased detector quality and reduces interference and false alarm. 4.Man-made factors. Someone smoking face to the smoke detector or push down the manual call point on purpose. Not obey the detector using rules. Fire alarm system quality 5.Engineering project design fault. Project design engineers are not technology certificated and made improper or wrong configure of the fire security project. A.Installation location is wrong or not suitable. B.Improper type detectors installation. For example, smoke detector is not suitable for garage and smoking room installation. 6.Poor installation of the fire alarm system NFPA72　National　Fire　Alarm　Code Chairman of the technical committee Wayne.D.Moore said that the main cause of false alarm is poor installation quality and pollution during construction. The fire alarm system should be installed after interior decoration of buildings to avoid pollution. The detector cover can prevent accidental mechanical damage and surface contamination only. A.The fire alarm system is not earthed or well earthed. It makes the system vulnerable to electromagnetic interference and cause false alarm. B.The construction quality is poor, the line insulation can not meet the requirements, the contact pressure of the connection is not good or the wiring is improper. 7. Component aging, dust accumulation and insect invasion. Component aging will reduce system reliability and make false alarm. Detectors with more than 10 years using time should be replaced or rechecked before use again. Detectors should be cleaned every one year. Dust proof, moth proof design for the sensing cavity.
