Smoke detector help

Your smoke sensor comes with batteries pre-installed. When the batteries are low, an alert is sent to your O2 Home hub, the smoke sensor light is unlit, and the sensor will chirp every 45 seconds until the batteries are replaced. The chirps can be silenced for 24 hours by pressing the TEST/SILENCE button.
