Press and hold the Test/Silence button on the alarm cover until the alarm sounds. It is recommended to test the alarm weekly to ensure the battery and electronics are functioning correctly.
USI alarms are typically designed with a 10-year lifespan. After approximately 10 years of operation, the alarm will emit an end-of-service life signal (often a chirp pattern), indicating that the entire unit needs to be replaced immediately.
No. The 10-year permanent power sealed battery is not replaceable. If the battery is depleted or the alarm reaches its end of life, the entire unit must be replaced.
Alarms should generally be installed in every bedroom, outside each sleeping area, and on every level of the home. Avoid installing directly in garages, kitchens, or extremely humid areas to prevent nuisance alarms, unless the specific model is designed for those environments.
