Why does my Firex smoke detector keep beeping even after I change the battery?

FireX recommends replacing the battery in the smoke alarm at least once a year to ensure proper operation. If the unit is wired to electrical power, a problem with the power supply can lead to false alarms and smoke alarm chirping. This scenario can occur when the power goes out or otherwise is interrupted.

Do hard-wired smoke detectors need to be replaced every 10 years?

After about a decade, your sensors will become weak and less efficient, which makes it less likely for them to perform their most basic function: detecting smoke in your home.
