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?

  • Turn off the power to the smoke detector at your circuit breaker.
  • Remove the detector from its mounting bracket and unplug the power supply.
  • Remove the battery from the smoke detector (if there is a battery).
  • With the battery removed, press and hold the test button for 15 to 20 seconds.

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.
