The 10-year battery backup allows for continued monitoring for the life of the alarm. Intelligent sensing technology is designed to reduce nuisance alarms; one button silences them if they do occur, and also tests detector functions. The latching alarm indicator automatically identifies which unit initiated the alarm, even after the conditions that set it off have subsided. And an end-of-life signal enhances your safety by letting you know when it's time to replace the unit. Connect it to compatible BRK or First Alert alarms within a single-family residence; connecting will sound all the alarms together.
