What are the causes of smoke alarm failure?

There are many kinds of smoke sensors, including household smoke sensors, wireless smoke sensors and independent smoke sensors. The failure reason is as follows: 1. Cooking; 2。 And the influence of water vapor; 3。 Smoke produced by smoking; 4。 Power supply; 5。 1. Many false alarms of cooking smoke are issued by ion alarms. Because this sensor is more sensitive to very small smoke particles, even if it is invisible to the naked eye. Smoke particles produced by high-temperature cooking are invisible to the naked eye.

2. Steam or moisture will concentrate on the sensor and circuit board. If the water vapor concentration is too high, an alarm will be given.

4. The battery will beep almost every minute (the interval and sound of different models will be different, but they all have the function of low battery warning). Some people will think that this is a false alarm.

If the alarm keeps ringing, it may be that the alarm has accumulated too much dust. You should consider replacing the alarm or cleaning it.
