The First Alert 9120 hardwired smoke alarm comes equipped with an ionization sensor to provide the earliest possible warning of a fast-flaming fire. The sensor is optimized to detect flaming fires, such as those caused by paper, kitchen grease, and other fast burning materials. The alarm also includes adapter plugs that eliminate the need for re-wiring if you are replacing an existing non-First Alert branded alarm. This smoke alarm can integrate with up to 12 other First Alert or BRK hardwired alarms and features a latching indicator that identifies which unit triggered the alarm.
