In the industrial field, most of them are using combustible gas alarm to monitor the change of combustible gas concentration. Its use can send out alarm signal when the concentration of combustible gas in the environment exceeds the set alarm value, and drive exhaust fan, solenoid valve and other equipment to prevent fire or explosion caused by combustible gas and ensure the safety of production operation. However, in the process of using the combustible gas alarm, many friends want to connect the combustible gas alarm with the security system. Can the combustible gas alarm be connected to the security system? The following is a brief introduction by yi yun Tian:

combustible gas alarm is composed of a gas alarm controller and a gas detector. The controller can be placed in the duty room and mainly control each monitoring point. The combustible gas detector is installed at the place where the gas is most likely to leak, the core component of the gas detector is a built-in gas sensor, which detects the concentration of combustible gas in the air. If only one or two detectors are installed, the alarm of gas leakage can be directly realized by the sound and light alarm on the detector. If the combustible gas detector is used in a large area, the detector is usually connected to the alarm controller first, and then the alarm controller is connected to the security control room.

The gas detector converts the combustible gas concentration detected by the sensor into an electrical signal and transmits it to the controller through the cable. The higher the combustible gas concentration, the stronger the electrical signal. When the gas concentration reaches or exceeds the alarm point set by the combustible gas alarm, an alarm signal is issued, and can start the solenoid valve, exhaust fan and other external equipment, automatically eliminate hidden dangers. In this way, when a leak occurs, the combustible gas alarm can activate these devices, such as a solenoid valve to cut off the gas pipeline, and the fan will disperse the leaked gas, thereby reducing the concentration of combustible gas in the environment and restoring it to a safe range.

to sum up, we can see that the combustible gas alarm can be connected with the security system. of course, if the number of combustible gas alarms installed is small and the leakage can be directly monitored, you can choose not to connect. Specific circumstances, should be based on the actual situation to choose whether to connect with the security system.
