Test your smoke detectors each month to make sure they are working, and change the battery at least once a year. A handy way to remind yourself to change batteries is to do it when you change your clocks for daylight savings time. Dust and dirt can accumulate in smoke detectors and reduce their ability to sound the alarm when needed. Cleaning can be done by vacuuming over and around the smoke detector regularly. Like any other electric appliance, smoke detectors do wear out eventually and should be replaced every ten years or as recommended by the manufacturer.
Smoke detectors save lives.
They alert sleeping or unaware occupants to the presence of fire and smoke and provide valuable extra moments that may be needed to escape. The devices also are required by the California Building Code to be installed in every residence, including rental property.
