First Alert Dual Sensor Smoke Alarm

The BRK 9120LBL alarm features a dual ionization smoke sensing chamber, an 85dB horn and a silence feature. This alarm features a 10 year battery backup. Under normal conditions you should not have to replace the battery for the life of the alarm. The Smart Technology system is designed to reduce nuisance alarms. Latching Alarm Indication remembers which unit initiated an alarm. When interconnected in a series, the unit that triggered the alarm rapidly flashes its red LED indicator. After the alarm condition subsides, the initiating unit will store in memory or latch the information and begin to flash the LED indicator 2 seconds on, 2 seconds off. The Perfect Mount system features a gasketless base and a mounting bracket that keeps the alarm secure over a wide rotation range to allow for true alignment.
