How to Install First Alert

First Alert smoke alarms contain a variety of useful safety features. A First Alert smoke alarm screws into a ceiling or wall and senses smoke using a photoelectric sensor with 360-degree access to the air. If smoke is detected, the First Alert smoke alarm plays a repeating sound involving three beeps and a pause. The First Alert smoke alarm includes a test button that activates the alarm, a beeping low battery alert, and a flashing light that signifies the unit is receiving battery power.
