Dangerous gas leakage Alarm Device Installation

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.

Gas detector explosion proof

Explosion-proof gas detector

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.

  1. 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.
  2. 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.
  3. 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.
  4. 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.
  5. 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.
  6. 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.
  7. Do not test the detector with high purity gas.
  8. 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.

Burglar Alarm System Installation Notes

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.

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.


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.





Intelligent Community Security FAQ

Intelligent Community Security will always be with problem in use and operation process. There are causes of design flaws, installation impropriety and improper use of security equipments. Here are some common problems and solutions.

Q&A:Confused mark or no label of wiring

Cabling system building is the longest security system construction period, the largest input of human resources, and also the most important part of the whole system. Most of them are concealed works in modern residential area construction, and they are permanent exist.
Chaos mark or even no mark Wiring  leads large trouble to the installation and maintenance of the project. At the process of equipment installation and commissioning time, no marked wiring will take the second manpower to measure the wiring. After completion of the project still marked unidentified or not marked wiring will cause difficulties to the maintenance work. So in the wiring process, each line must be clearly marked, so that not only can save installation costs, but also facilitate the installation and commissioning of the project.

Q&A: No waterproof and sun protection measures for outdoor wiring

The outdoor wiring must have waterproof and sun-proof measures to prolong the system life and ensure the security system stability.


1. Wiring system by connecting terminals indoor as far as possible even extenting wiring. Can use hand in hand wiring for bus system.
2. The outdoor terminal of the system can be sealed. The treatment causes inconvenience for system maintenance but can prolong system life and enhance reliability.  If need to disassemble the wiring, it must be re-sealed at the end.
3. Using outdoor distribution box for all outdoor termination of the wiring. Put all outdoor line terminals into the terminal box. This method not only solve the outdoor end waterproof sun-proof problem but also easy maintenance.

Q&A: The installation height of intercom host is not appropriate

Most of the intercom host is installed at the bottom of 1.5 meters from the ground. But the host height are different for different manufacturers, the specific needs of the installation height must be based on the entity concerned. It should be in accordance with the standard of the height of the camera, so as to make the indoor monitor more clearly see the visitors. There are some residential units gates in front of the ladder, thus causing the visitors standing height is not the bottom of the door frame bottom but one or two steps lower. The installation position of the intercom host height should be confirmed according to the spot.
Most of the intercom hosts are not water-proof. If they are installed on wall without rainshed, the security system stability and using life will reduce.


1. Install the intercom host on the gate.

2. Add rainshed or waterproof kit for the intercom host.

Q&A: closed-circuit monitoring system and power supply system are in the same tube 

Put closed circuit television line and power lines parallel and even in the same pipeline. The monitored images will be distorted cause of the power electric interference.


1. Use better shielding effect cable or even double shielding cable.
2. Even in the same pipeline,  use plurality of line pipe and tube wiring. Not wiring the circuit in same line pipe of the the power line.
3. When wiring in elevator, make sure to get distance between the power line. The elevator is using a strong power, the interference is large. The greater the longer distance between the CCTV line and power supply line.
4. Increase anti-interference equipment.

Q&A: Exposing household privacy in closed circuit monitoring system

The community monitor can easily see the residents’ house, the home owner’s privacy will be exposed imperceptibly. If there is a video data gratuitous transfer, it will cause great harm to the owners, there may even make a lawsuit.


1. Select appropriate location to install the security cameras. The security cameras should be mainly installed in the square and traffic corridors and other public places.
2. The security cameras should avoid to toward to residential direction especially residents gate, doors and windows, balcony.

Q&A: Parking card reader location is not appropriate

There are ID, IC two types card readers with legibility distance from 10 cm to 10 meters. For the long distance card reader, the driver does not actively take the card, as long as the card is placed in the car, it can be automatically read when the car pass through the card reader. For the close to 10 cm card reader, the driver must roll down the window and took the card in front of the card reader.  So the reader must be installed in the position where driver can easily reach. Some areas due to restrictions on the site, the vehicle can not turn in and out and smoothly access the card reader. The drivers must get off to access to card readers. It caused inconvenience for residents.

Solution: Fully inspect the site, select the appropriate location to install parking management equipment.

Q&A: Perimeter protection system is installed as normally open alarm mode

There are normally closed (N/C) and normally open (N/O) two types alarm modes for wired alarm systems. But N/O is not fit for perimeter protection system installation. For N/O circuit, when the security system is cut off, the system will not trigger alarm. For N/C circuit, when the security system circuit is cut off, the system will trigger alarm.

Solution:N/C circuit is suggested for perimeter security system burglar alarm.

Q&A: Electronic patrol route is not suitable

There are wired electronic patrol and wireless electronic patrol. Wireless electronic patrol is with advantages of easy installation and maintenance and stable system. So, wireless electronic patrol is popular nowadays. Improper patrol route will cause inconvenience for security patrol staff. It may require the patrol staff passing the lawn to arrive patrol location. At rainy and snowy days, that caused great inconvenience.


1. Design patrol route as “S” style and without blind corner.

2. Patrol point should be installed in the places where the patrol staff can easily reach, such as the location of the roadside, the front of the unit gate.

Q&A:The home security system PIR is installed toward to the windows

The false alarm may be produced by improper security sensor installation. If the Infrared Detector (PIR) is installed toward to the windows, the movement and activity in outdoor may produce false alarm.


Avoid to install indoor PIR toward to windows or choose multiple intrusion technology security sensor for strong environment interference resistance.

Conclusion: There are many problems and difficults installing community security systems. Only if we thoroughly inspect the site and strickly install the security system according to instruction, the community security system can work smoothly. The later maintenance can be easy with properly planed and installed community security system. 






Install Infrared Beams Detector

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.

Install Beams Detector on wall

How to Install Infrared Beams Detector on wall

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.

Fixing Photoelectric Beam on pillar

Use Infrared Beams Detector to stop illegal climbing over the wall

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.

Fixing break beams on wall by pillar

How to install break beams

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.

Pet immune Motion Detectors and the technology

Pet immune motion detectors are required to be installed in house where pet is living. The pet immunity motion detector can identify moving of pet and human. So, it can avoid false alarm caused by pet movement.

Intrusion Detector PET Immunity

home security system

Security systems manufacturers are adopting new digital technology to make pet immune motion detectors.
Generally, there are 2 ways of pet immunity technology. One way is changing design of Fresnel lens. The fresnel lens will refract or reflect Pyroelectric infrared signal to PIR. It will divide the detection area into a number of bright and dark regions. Changing the area division way can reduce the false alarm caused by small pet. But the effective is minimal.
Another way to reduce false alarm caused by pet is MCU processing. The MCU will collect the detected infrared signal. Then it compares that with sample signal of human movement. It analyzes the signal cycle, volumn, polarity. If the detected frequency range is 6-12Hz, the system judges an activity as a pet activity and does not generate an alarm. If the detected frequency range is 0-5Hz, the system generates an alarm.
There are maximum 15kgs, 20kgs, 35kgs pet immune motion detectors. Home owners should select the corresponding one to fit the pet weight.
Correctly installing the motion detector is important to reduce false alarm. There are installation note for pet immune motion detectors. It is required to install the detector according to the manual.
There are 4 notes when install the motion detectors.
1. Installing height
Install the motion sensor at required installing height. Otherwise, the detection distance may be shorten. The pet immunity effectiveness will be decreased.
2. Installing angle
3. Installing place
PIR motion detector should be avoid installing at some places where interference may be generated.
4. Installing direction
It is best to keep potential intrusion direction and detection area of PIR as 90 degree.
Digital technology is developing. So, in the future, the motion detector will be more intelligent and easy to use.

Smoke Alarm types and connection

Smoke alarm is important component of fire alarm system. And it is part of home security systems.
The smoke detector alarm can be used with fire alarm system or burglar alarm system or independently sound and light alarm on-spot without connection with any alarm systems.
So, there are 4 types of wired smoke alarms. (same as heat detector, CO detector and compound detector). The connection way is different for different types smoke detector alarms.
Correct connection is required to ensure proper work of smoke alarm. Otherwise, danger will be heavier with non-work smoke detector alarm.
We need to buy correct type smoke detector to work with our exist alarm systems. And we need to wire the smoke alarm according to the detector’s manual and alarm receiver’s manual as well.
Below we will introduce these 4 types smoke alarm and connection ways (Smoke alarm type is HST brand as example. The HST brand smoke detector can be bought at Vedard Alarm Store)
Type 1: Independent Smoke Alarm.
The independent smoke detector alarm doesn’t need wire connection. It makes sound and light alert when smoke density reaches to alarm limit. The independent smoke alarm can be battery powered or AC powered with battery power backup.
Type 2: Bus type coded addressable smoke alarm
There are 4 terminals and only terminal 1 and 3 are non-polarity connected to 2-wire bus type fire alarm control panel L1 and L2.

etc. The professional designed alarm system will have these functions for installer to program alarm system.
But most people maybe not clear of the meaning and ignore them. If you understand the terms well and set as what you need, the alarm system will be much more convenient and secured.
So, no matter professional security service or DIY security alarm installer, understanding the alarm system programming terms is important and essential.
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.

Test Method and Notes for the Solar Powered Wireless Beams


Security Service New technology alarm detection

Solar perimeter beams for security service.

. 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.

Home Alarm Security Service Development and the importance

Home Alarm Security Service includes security service training, security alarm equipment installation and security monitoring etc.
It plays important role and grows along with home security technology and the industry development.

Home security service began by establishing security monitor center with security alarm equipment. It will grow quickly along with development of security alarm industry and broad application of Video monitor and TCP/IP fast network replacing PSTN network. Technology improvement of computer, smartphone, tablet etc. will help to promote home security alarm device and the service with function of home monitor, house appliance controlling and integration with smart home systems.

Service industry is trending integration. Home security service will be able to deal with business of community management as well. It is possible to foresee that it can deal with more intelligent service business in the near future. Some companies which providing communication service are trying to enter into this area as well.

Security alarm installation service is very important for correct choosing and installation of alarm systems and teaching users to operate it properly. Even DIY home security is popular nowadays with humanize alarm products. But high rate false alarm is existing due to wrong operating and incorrect products’ choosing, sensitivity adjustment etc. It requires professional installation and correct selection of alarm products to ensure the system working reliably and accurately.

On the other hand, the development of home security alarm service helps promotion of the alarm security equipment innovation and improvement of the industry.

There are still many factors hinder the development of the security alarm service in many countries. In some countries, there is license or certificate for security alarm installers. But in many other countries, like in China, there is still no business management policy for home alarm security service. The alarm installers help installation for friends or acquaintances only. Home owners know little about Security alarm systems yet and not know how to install it even there is user’s manual. Anyway, home alarm system is somewhat technical things.
So, home security service training and government management for the industry is important. And home security service is still with large market for growth.

Security service development and importance

Security service development and advanced technology wireless burglar alarm systems.

Additional wireless detectors to existing alarm system

Hardwired detectors’ usage is with cons of complicated installation and distance limitation. So, wireless alarm system is more and more popular nowadays.

Wireless detectors is more convenient for updates of existing burglar alarm and fire alarm systems. It enables it easy for the existing alarm system to add any quantity detector and change detection area, repair detection line error etc.
Of course we need a converter which will convert the wireless alarm signal to wired output and link to existing alarm panel.

For example, wireless smoke detector, wireless smoke and heat detector, wireless gas sensor can be easy to add to existing fire alarm system.
The wireless fire detectors can be added to existing burglar and Fire home security alarm panel which has the wired zones port with N/C or N/O circuit. The wireless fire detectors can be added to conventional fire alarm panel as well.

Add wireless detectors such as pir or named motion sensor, outdoor active infrared detector, door contact, smoke detector, heat detector, CO detector, Gas sensor etc. at any place you want.  Then install the wireless to wired converter at place where within the distance required.  For example, the wireless detector transmitting distance is 200m, and converter receiving distance is 150m, then the distance between converter and detector should be within 150m.  
And please make sure wireless detectors can work with the converter with same wireless coding way.  Generally, manufacturers have their own wireless coding technology for their own wireless products. So, it is important to make sure of it.
