When should a smoke detector be tested?

A smoke detector should be tested at least once a month because regular testing ensures that the device is functioning properly and can effectively alert occupants in case of a fire. Frequent testing helps identify any potential issues, such as low batteries, malfunctioning units, or improper placement. This regular maintenance is critical for safety and compliance with fire codes.

While testing during fire drills or when new batteries are installed can help, relying solely on those occasions does not establish a consistent practice for ensuring the detector's performance. Monthly testing offers a more proactive approach to maintaining fire safety in a building.
