Hotel smoke alarm flashes.

Of course, it has a monitoring function, but it monitors cigarettes, not people.

Smoke alarm In normal operation, most brands of smoke detectors have indicator lights flashing, which usually flashes slowly (1 minute) when working, and the red light flashes quickly when detecting fire smoke alarm.

The smoke alarm has only one flash. Once the smoke from the outer ionization chamber escapes and interferes with the normal movement of charged particles, the current and voltage will change and destroy the balance between the inner and outer ionization chambers, so the wireless transmitter sends out a wireless alarm signal to inform the remote receiving host and transmit alarm information.

There are two situations when the smoke sensor keeps ringing:

First, because the dust of the alarm is too large, after the smoke alarm is used for a period of time, the sensitivity of the detector maze will be improved due to dust accumulation, resulting in false alarm or alarm when there is less smoke. This situation is particularly obvious in some places where the dust in the air is relatively large. At this time, it is necessary to contact manufacturers or professionals to clean the detector maze.

Second, the installation position of the alarm is not good. Household smoke alarms are generally installed in the living room, study or bedroom, but some families are installed in the kitchen or installed too close to the kitchen. The kitchen itself is a smoky, hot and humid place. Installing smoke alarm here may not only produce false alarm, but also affect its service life.

If the smoke alarm at home keeps ringing, first check the whole room to make sure there is no fire. If it is a false alarm, check it according to the above method. If you can't solve it yourself, contact the manufacturer in time.

Therefore, when installing the household smoke sensor, we should not only pay attention to selecting the appropriate location, but also pay attention to maintenance and cleaning, so as to avoid the false alarm of the smoke sensor and cause panic.
