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.

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.

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.
