Questions regarding combustible gas detectors
Thread Content
Today, during the safety inspection, the combustible gas alarms in the factory area were tested. The alarms on site issued sound and light alerts, but the combustible gas alarm controller in the control room did not give any alert (it had not been reset for a week). After resetting it, the tests were conducted again, and both the on-site alarms and the alarm controller in the control room functioned properly. What could be the reason for this? Could it be because it wasn’t reset?
Yes, you didn’t reset it, or you pressed the mute button directly, that’s why there was a bug. For a normal alarm, once it triggers an alert during use, the alarm light remains on if the reset button is not pressed. If the control room alarm light is not on, and there has been no previous unresolved alarm. The problem you mentioned, OP, has occurred; you need to get in touch with the manufacturer. It should be reset after each alarm, but do I still need to reset it regularly when there is no alarm? Right?……
This is possible; it might be due to the design of the DCS system, and this alarm should be real-time
This of yours should be a police alarm controller. It’s likely that an alarm was triggered previously but wasn’t reset, so the sound was silenced directly. The alarm controller must be reset after an alarm occurs in order to function properly
What he meant is probably a GCS, not a DCS

Go bald and shave off your facial hair. Even if a button is pressed by accident, the alarm should reset automatically after some time, allowing the program to resume its normal operation. How dare you let the alarm keep going like an idiot – why isn’t it sounding anymore? The software is such garbage........... .
What I encountered was that the alarm controller failed to reset after an alarm was triggered, and it ended up in the situation you described
There is a problem with the alarm settings in the operator’s control room; whether or not it is reset, as long as a new alarm occurs, the controller will trigger an alarm. The reset function is often provided by some controllers, which have outputs to operate valves or fire pumps.
