Like any appliance, smoke alarms require routine maintenance and testing to help ensure that they will operate when required. The instruction manual provided by the manufacturer will list the specific maintenance and testing procedures required for your smoke alarm. Typical maintenance and testing activities include:

• Vacuum dust from alarms at least once a year

• Test alarms monthly by pushing the test button

• Replace alkaline batteries at least once a year and anytime the alarm “chirps,” warning that the battery is low

Smoke alarms will wear out over time. Ten years is the recommended replacement time. After operating 24 hours a day for ten years, even a well maintained smoke alarm will have a 30 percent chance of failing to operate in a fire. It is a good idea to write the installation date on the inside of your alarm with a marker so you will know when to replace it.

Please remember this is a homeowner responsibility.
