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.

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.

 

 

 

 

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.

Community Security System building

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.

Solution:

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.

Solution:

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.

Solutions:

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.

Solutions:

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.

Solutions:

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.

Solutions:

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.

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.

Flammable gas alarm installation and inspection

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.

Gas alarm with gas leakage detector and monitor

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.

Solenoid valve is a popular security kit to shut off the gas immediately. (less than 1 second). Below we will show how to install and operate the solenoid valve for home security and small business security such as hotel, restaurant.

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.

install solenoid valve

Installation illustration:

1. The solenoid valve should be installed by professional personal according to gas pipeline construction regulation.

2. The valve should be installed following the indoor air inlet valve for easy maintenance. Refer to picture above. 

3. The solenoid valve should be installed in the direction of airflow marked. The body coil shall not be inverted. Both horizontal and vertical installation is allowed. 

4. The control line of the solenoid valve should be connected correctly and reliably. The control line has the polarity: the white line is the positive pole, the black line is negative, and reverse connection is not allowed.

5. Please remove the solenoid valve when cleaning the gas pipeline to avoid valve seal material damaged by sundries.

6. The solenoid valve should be opened when the gas pipeline is under seal performance test.

7. Manually open the valve when pressure is balance between inlet and outlet of the valve.

8. Do not wrong connect the control line including wrong polar, wrong voltage, and long time powered. 

Wiring requirement:
Wiring: 2*0.75mm²   Double core retaining wire, terminal pressing method connection.
Control distance: It adopts capacity discharge driving mode and control wiring should be less than 50m.
Maintenance of the solenoid valve:
It requires regular maintenance.

Wireless coding Alarm Security Technology

Compared with wired alarm system, wireless alarm system is with advantages of easy installation and long range transmitting.
But vulnerable wireless communication (easy to interfere and copy by professional equipment) is what people worried.
Thanks to technology development, it enables wireless alarm system as reliable as hard wired alarm system.
The transmission codes used multiple coding and scrolling coding technology. It used 2^44 code combinations in total with Scrolling code encryption technology to ensure high security of code transmission.
Thus Wireless Alarm System is as secure and reliable as hard wire alarm system and more easy for installation.
