FIRST ALERT SA304CN3 Smoke Alarm with Escape Light - Battery Powered

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. The First Alert smoke alarm with escape light not only alerts you to smoke and fire with a loud 85-decibel alarm, but also illuminates your path to safety. It uses ionization smoke sensing technology with a new contemporary enhanced smoke gathering design. It also features a low battery alert to remind you when to change the battery and has a missing battery guard to ensure that a battery is placed inside the alarm. The side battery drawer slides open for easy battery replacement. A blinking power indicator on the unit confirms that it is receiving power. The silence/test button allows you to both silence a non-threatening alarm and to test the unit's functionality. The alarm contains an optional pin to lock the battery and unit in place for tamper resistance. It can be mounted on either the ceiling or the wall and can be used in mobile homes and RVs. It includes one 9-volt battery and has a 10-year limited warranty. Replaces the old SA150 model. UL listed for safety. Not permitted for sale in Oregon.--Bree Norlander

During testing you will hear a loud, repeating horn pattern: 3 beeps, pause, 3 beeps, pause. The Escape Light will turn on. LED flashes once every second
