First Alert SA9120BPCN Smoke Alarm

The First Alert Hardwired 120-Volt AC Ionization Smoke Alarm with Adapter Plugs can be instrumental in protecting your family and your home in the event of a fire. This hardwired smoke detector acts as an alarm wired directly into your home's electrical system. Intuitive additions such as a side battery backup drawer ensure that your alarm will perform in the event of a power outage. The inclusion of adapter plugs removes the stress and burden of replacing other non-First Alert branded detectors without rewiring.
