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.

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.

 

 

 

 

Fire prevention and escape

Fire prevention and fire escape basic knowledge should be awared by all people. If people can aware of fire dangers and take action to prevent fire, the fire incident can reduce at lease 30%(According to fire department report of fire incident causes). If people have fire escape and fire incident self-saving common sense, the fire caused loss can reduce at least 50%(According to 2015 fire department report).

We have an article about fire precaution and today we will again share common sense of fire escape. Keeping calm can largely reduce the development of fire. The fire can be easy extinguished at initial stage.

But to effectively extinguish fire, we should identify the cause of fire and use the corresponding method. There are several causes of fire.  Most fire can be extinguished by water. But some special fire should not be extinguished by water.  The special fire causes are Oil, alcohol and same types fire, gas fire, electric appliance fire. Oil and alcohol fire and gas fire can be extinguished by sand or wet towel. Then the gas source should be cut off and door, windows should be open. Electric appliance fire should be extinguished by dry powder or gas fire extinguisher. And cut off the electric power supply As Soon As Possible. Or cut off the electric power supply firstly and use web towel to extinguish the fire.

Use the feasable objects nearby to quickly extinguish fire. Cooking fire can be extinguished by pot lid, cup lid or basin or plate. Salt can be used as fire extinguisher for some situation such as cooking fire. metal fire. Besides of these “fire extinguisher”, Sand, Wet cloth, mop, wet blanket can be used to extinguish the fire.

Use feasible objects nearby to extinguish fire

Escape from fire: if the fire is too big, we should escape from fire as soon as possible and call fire department and notify neighbors.

1. If the escape route is blocked by fire, smoke, we should return to room and sealed the room door with wet cloth to stop fire spreading to room. Fetch water to drop temperature of the door.

2. If the escape route is open, we should escape as soon as possible. At fire spot, there are too much smoke bluring the escape route. So, we should keep the escape route in mind. We can mask our eyes with transparent plastic bags and noses, mouths with wet cloths to block smoke.

3. Do not take the elevator but stairway to escape. The elevator electric power can be cut off by fire and it will be filled of smoke. So, except for fire elevator, do not take elevator on fire incident.

Anyway, fire prevention is the first step and most essential step to avoid fire incident.  We at Vedard Security offers many security equipment for fire prevention. But if fire incident happens unfortunatelly, we should keep calm and try our best to save ourselves.

 

 

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.

Solar-powered wireless infrared grating

Questions for Solar-powered wireless infrared grating
1.Are your devices functional in low temperature (-2 to 15 degrees) in winter time, (17 to 35 degrees) during summer time?
Our detector supported working temperature range :-30C~70C. Can work at extreme snow weather condition such as Russian, USA.
2.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
3.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
4.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.
5.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.
6.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.
7.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.
8.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 ,but that will reduce wireless distance and anti-interference function.
9.What happens if a bee, or a bird passes through the IR-fence?Bee or bird flying cant trigger the sensor?
Bee or 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.
10.Works in the light for 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 .
Secondly, the static power of our sensors is only 1% of traditional wired sensor(static power:0.5mA). the sensors have high-capacity LFP battery inside,can keep the sensors working much more than 15 days without charging.
11.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.

Detect and monitor gas leakage with gas alarm device

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.

Operation illustration:

  1. The solenoid valve is at open state normally. There are two ways to close the valve and shut off the gas source. one way is providing DC pulse current (DC9V-12V) to close the valve. The valve will be closed in 1 second. That is the way we used to quickly shut off  leaked gas source. Another way is opening the protective cover and manually press down the red handle to close the valve. It keeps close state.
  2. How to open the solenoid valve? There is only one way to open the solenoid valve. Opening the protective cover and pulling up the red handle to open the valve. If it is hard to pull up the valve, then please take measures to balance the inlet and outlet pressure of the valve at both ends. Then reopen the valve after balancing the valve. Avoid barbaric operation to damage the valve actuators.
  3.  Valve at open state: The valve may automatically close subjected to harmful strong vibration caused it is designed according to magnetic lock principle. But if the opening valve self-locking force is too small, then maintenance is needed.
  4. If the solenoid valve is emergency closed, then the gas leakage or other  hidden accident dangers should be eliminated before open the valve.

Test Method and Notes for the Solar Powered Wireless Beams

1

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.
