Question: Why Is My Smoke Detector Beeping Every Minute?

If your smoke alarm is beeping just once every couple of minutes this usually means a low battery.

Even if your smoke alarms are hardwired they still have batteries.

If your smoke alarm is beeping 3 times in a row followed by a short pause repeated, this means there could be smoke in the house.

How do I stop my fire alarm from beeping every minute?

  • Remove the detector from its mounting bracket and unplug the power supply.
  • Remove the battery from the smoke detector (if there is a battery).

Why is my smoke detector beeping every few minutes?

The battery drawer must be completely closed for the battery to make contact with the terminals. As the battery in a smoke alarm becomes weak, the smoke alarm will “chirp” about once a minute to alert you that the battery needs to be replaced. Note: Only the alarm with a low battery will chirp.

How do I tell which smoke alarm is beeping?

Locate the reset button on the surface of the smoke detector. Hold it for 15–20 seconds and then release. Wait a couple of minutes and listen for the chirping noise again.

A hard-wired smoke detector usually chirps because of 1 of these 3 problems:

  1. A dead backup battery.
  2. Dust inside your detector.
  3. Malfunctioning/old detector.
