Smoke alarms should be tested how often?

Testing smoke alarms monthly is recommended to ensure that they are functioning properly. Regular testing helps to identify any malfunctioning units early, ensuring that they will operate effectively when needed, such as during a fire. Smoke alarms are a critical component of fire safety, as they provide early warning to occupants, giving them precious time to escape.

In addition to monthly testing, it is essential to replace batteries at least once a year and the entire smoke alarm unit every ten years, as they can degrade over time. Monthly testing helps maintain the reliability of the alarm, making sure it remains a vital safety tool in fire prevention and response efforts.
