How often should smoke alarms be tested?

Smoke alarms should be tested every month to ensure they are functioning properly and ready to alert occupants in the event of a fire. Monthly testing allows individuals to check the battery and operational status of the alarm, providing an ongoing reassurance of safety in the living environment. Regular testing and maintenance, such as replacing batteries at least once a year, greatly increase the effectiveness of smoke alarms in preventing fire-related injuries and fatalities.

While testing every week can be excessive and may lead to alarm fatigue, testing every three months or annually does not provide the regular check necessary for optimal function, especially in households where the smoke alarms might not be subject to significant wear. Therefore, monthly testing strikes a practical balance between ensuring alarms are in good working order and not overwhelming individuals with too frequent testing.
