Smoke Detector Maintenance Guidelines

It is vital that all smoke detectors be properly maintained and stay operational at all times.

Testing

The National Fire Protection Association (NFPA) recommends testing all smoke detectors once a month to make sure they are operating.  "Test each alarm by pushing the test button and listening for the alarm.  If you can't reach, stand under the alarm and push the test button with a broom handle.

Replacing Batteries All batteries should be replaced according to the manufacturer's instructions.  The NFPA recommends "doing this at least once a year or when the alarm chirps, alerting you that the battery power is low.  Replace the batteries immediately if you move into a new home."

Cleaning

Dust and cobwebs can interfere with the proper operation of a smoke detector.  They may cause the detector to become less sensitive or even more sensitive in some cases.  Smoke detectors should be cleaned regularly according to the manufacturer's instructions.  Smoke detectors generally can be cleaned with a standard vacuum cleaner hose and attachment. Do NOT remove the detector's cover when cleaning.

Replacement

Based on statistical performance information, it is recommended that smoke detectors be replaced every 10 years or as monthly testing indicates.
