Why is my smoke alarm beeping every few hours or every other day?
The most common cause of smoke alarms beeping (and the easiest to fix!) is simply the battery is getting low and needs to be replaced. If you put in a new battery and the problem persists, there may be an issue with the sensor, an electrical problem (for a wired smoke alarm) or the alarm may be reaching the end of its life and will need to be replaced.
