Smoke alarm
mainten­ance guide

Once a month

Test your smoke alarm batteries by pressing and holding the test button for at least five seconds until you hear the beeps.

Vacuum dust off your smoke alarms.

Keeping your smoke alarm free of particles will help reduce false alarms and ensure smoke can easily reach the internal sensor.

Every year

Replace lead or alkaline batteries.


Every 10 years

Replace all smoke alarms every 10-years, or earlier if specified by the manufacturer.
