For smoke alarms powered by a primary battery, what must the weekly testing ensure?

The requirement for weekly testing of smoke alarms powered by a primary battery is to ensure that the alarm can function properly. This means that the alarm should sound and respond effectively to simulate a fire condition, confirming that it is capable of alerting occupants in case of a smoke or fire event.

While checking the battery charge or condition, operational status of components, and correct installation may be important aspects of overall alarm safety and function, the primary focus during the weekly tests is on the operational capability of the alarm itself. This ensures that it will work effectively when needed most, thus protecting lives and property by providing timely alerts.

Regular testing of the alarm's functionality is a crucial practice to maintain a reliable fire safety system, as a non-functioning alarm can lead to devastating consequences in the event of a fire.
