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.
