First Alert Hardwired Smoke Alarm

This First Alert Hardwired Smoke Alarm includes a 10-year battery backup that continues to protect you in the event of a power failure. It uses an ionization smoke detector, and features a loud 85-decibel alarm. One button silences any nuisance alarms, and also tests detector functions. The latching alarm indicator automatically identifies which unit initiated the alarm, even after conditions that set off the alarm 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 up to 12 compatible First Alert or BRK devices (sold separately) within a single-family residence.
