At present, combustible gas alarm, as the 1 safety equipment to detect the concentration of combustible gas, has been widely used in petroleum, chemical industry, metallurgy, coal mine, city gas, industrial manufacturing and other fields. When it detects that the concentration of combustible gas in the air reaches the critical point set by the explosion or poisoning alarm, it will send out an alarm signal to ensure production safety. However, there are many friends, in the process of use, sometimes encounter the problem of combustible gas alarm has been ringing. Do you know how to disarm combustible gas alarm ? The following is a brief introduction by yi yun Tian:

method of releasing combustible gas alarm all the time:

1. Reduce the gas concentration at the place of use

The gas concentration in the place where the combustible gas alarm is used is too high and the gas cannot be dispersed, need to close the solenoid valve to open the window, the gas is reduced to a suitable concentration range, then the combustible gas alarm alarm will automatically release.If the combustible gas alarm is still a constant alarm, there may be a leak source, and the leak point needs to be repaired.

2. Set the alarm value within a reasonable range

the alarm value of the body alarm is set at 25% LEL by default, if the alarm value is set too low, the alarm will sound if the alarm is too sensitive. Therefore, we will set the combustible gas alarm alarm value within a reasonable range can effectively solve the above problems. Of course, if the alarm value of the combustible gas alarm is set too high, too high alarm value is not sensitive, will pose a threat to people's lives.

3. Replace the gas sensor in time according to the service life

most combustible gas alarms use catalytic combustion sensors, the service life is about 3-5 years, and the alarm value of the gas sensor will shift if it is used for too long. It is necessary to replace the probe in time.

4. Check the installation wiring of the combustible gas alarm

If there is a problem with the line, if the combustible gas alarm host fails to inspect, the probe will report a fault. If it is a bus probe, it will report a fault if it does not provide 24V voltage to the probe. Therefore, we check the installation line of the combustible gas alarm to ensure the normal use of the line, which is also one of the ways to release the combustible gas alarm.

To sum up, this is the way to disarm the combustible gas alarm. Through these methods, we can effectively relieve the problem that the combustible gas alarm has been ringing. If through the above method, or can not remove the combustible gas alarm has been ringing the problem, please immediately contact the manufacturer for processing.
