Smoke detectors are an essential safety feature in homes and buildings, and are designed to alert residents as quickly as possible after a fire begins. However, they occasionally can generate false alarms.

Working smoke detectors are an important safety feature in your home.

Batteries are Low

The most common cause of a buzzing smoke detector is weak batteries. As a safety precaution, smoke detectors will begin to buzz or chirp every few minutes when the batteries are low as a signal that they need to be replaced.

Cooking Smoke is Reaching the Detector

If your detector is placed near a stove, oven or fireplace, some of the smoke may reach the detector. Many detectors come with a "false alarm control" button that allows you to turn off the alarm temporarily if know you are about to engage in an activity that may generate smoke.

The Detector Needs to be Cleaned

Dust, dirt and pet hair can interfere with the operation of a smoke detector, and this may cause false alarms. Consult the manual for your model of smoke detector for instructions on how to clean it without causing damage.
