What's wrong with smoke alarms all the time?
Dust. If the alarm keeps making an alarm, it may be too much dust in the alarm.Solution: consider changing the alarm or cleaning it. When cleaning the alarm, the end of the vacuum cleaner is closed to each other by the opening around the alarm. Thus, the dust accumulated in the alarm can be completely removed.
Cigarette smoke. In general, smoke alarms do not respond to cigarette smoke unless smoke is very dense, for example, many smokers smoke in the same room. If the alarm is too old, it will respond even if the smoke is low. So, on the contrary, we can judge whether the alarm is aging or not.
If your alarm sounds intermittently, you can replace the battery to see if it can solve the problem.
Case 1: power supply. When the battery is running out about every minute will make the chirp sound (different models in the interval and the sound will be different, but there is lack of electricity, there are early warning function) will think this is a false alarm. But the sound is very different because it sends out a single, short sound, and sounds like this about every minute.
