What is the alarm of the building fire protection system?

According to the specific alarm information,

Fault alarm refers to the failure of fire control point, and the alarm is eliminated after the failure is eliminated.

Smoke and temperature alarms indicate a fire, so you should go to the site immediately for inspection. If it is determined that the false alarm is mostly caused by dust or steam, it can be eliminated after reset. If a certain point has been falsely reported, it may be that the probe is too dirty or damaged, so it should be cleaned or replaced in time.

The water flow indicator gives an alarm, indicating that there is liquid or gas flowing in the spraying official website, which is mostly caused by damage and leakage of nozzles or pipelines, and should be inspected on site.

Feedback alarm means that the equipment has action. For example, after the normally closed air supply outlet is opened, the host computer displays a feedback alarm, and the alarm is eliminated after the air supply outlet is closed. If the device doesn't work, a feedback alarm will be displayed, indicating that the wiring of the device is wrong. Just adjust the wiring of normally open and normally closed contacts.
