If a smoke alarm fails a sensitivity test, what should be done?

When a smoke alarm fails a sensitivity test, replacing the unit is the most appropriate course of action. Smoke alarms are critical safety devices designed to alert occupants of smoke or fire, and their reliability is paramount. A failure in a sensitivity test indicates that the alarm is not functioning correctly and may not activate in the event of an actual fire, which poses a serious safety risk.

Replacing the unit ensures that the new smoke alarm meets the required sensitivity standards for detecting smoke. This action contributes to the overall safety of the environment and adheres to fire safety regulations. It is essential to prioritize the efficiency and effectiveness of fire detection devices, making replacement the ideal solution for a failed sensitivity test.

While other options, such as cleaning the smoke alarm or checking the battery, are helpful maintenance practices, they do not resolve the underlying issue of a failed sensitivity test. Recalibrating a smoke alarm is not typically an option since most commercial smoke alarms are not designed to be re-calibrated after installation. Therefore, when faced with a failed sensitivity test, replacing the smoke alarm is the best practice to ensure optimal performance and safety.
