Working smoke alarms cut the risk of dying in a home fire by 50%, and that's important because a home fire starts every 83 seconds! The faster you know about a fire, the faster you can start moving your family outside. First Alert's SA9120BCN alarm with battery back-up uses ionization smoke sensing technology and sounds an 85-decibel alarm. A power indicator on the unit confirms that it is receiving power and a silence/test button checks all alarm functions and silences a non-threatening alarm.
