How frequently should a smoke detector be tested for proper operation?

The recommended frequency for testing a smoke detector for proper operation is monthly. Regular testing ensures that the smoke detector is functioning correctly and can adequately alert occupants in the event of a fire. Monthly tests help identify any potential issues, such as dead batteries or malfunctioning units, allowing for timely maintenance.

While some sources may suggest that smoke detectors can be formally inspected or replaced every five years, this does not replace the necessity of regular monthly testing. It's essential to keep the detectors in optimal working condition to enhance safety measures in residential or commercial spaces.
