Hardwired Smoke Detector with Battery Backup - 1 Pack

The First Alert 9120BFF Hardwired Smoke Alarm with Battery Backup is designed to promote greater household safety. This 120-volt AC smoke detector utilizes an ionization smoke sensor to reliably detect smoke from hot, fast-flaming fires and alerts you with a loud 85-decibel alarm. Engineered to be hardwired directly into your home's electrical system, this smoke alarm features a backup battery that helps ensure the alarm continues to function even during a power outage.

The alarm's gasket-less mount facilitates easy installation and ensures proper alignment, while tamper-resistant locking pins keep the device secure. The convenient test/silence button allows you to easily check the alarm's functionality and mute false alarms. This smoke alarm can integrate with up to 12 other First Alert or BRK hardwired alarms, and it features a latching indicator that identifies the unit that triggered the alarm.

Introducing the BRK 9120 series smoke alarms, which have been redesigned from the ground up. These alarms install faster, perform better, and are even smarter than their predecessors. These improvements help reduce nuisance alarms, saving you time and money. BRK Electronics smoke alarms are designed to be easy to install, easy to maintain, and quality-engineered for years of virtually maintenance-free service.

The 9120B AC-powered smoke alarm with battery backup includes an ionization sensor to detect fast-flaming fires that consume combustible materials rapidly. It is 120-volt AC inter-connectable, with a maximum of 18 compatible devices. The alarm can be interconnected with up to 12 other compatible smoke alarms and six compatible devices, such as bells, horns, repeaters, and door closers. If one unit triggers an alarm, all smoke alarms in the series will sound, and power indicators will show which unit initiated the alarm.

The 9120B features smart technology to reduce nuisance alarms and a 9-volt battery backup for peace of mind during power outages. Its single test/silence button both silences a non-threatening alarm or low-battery warning and allows you to test the unit's functionality. The perfect mount system includes a gasket-less base for easy installation and a new mounting bracket that keeps the alarm secure over a wide rotation range, ensuring proper alignment. Tamper-resistant mounting brackets and a dust cover provide additional protection.

Backed by a 10-year limited warranty, all BRK Electronics smoke alarms meet the UL 217 standard and are listed with the California State Fire Marshal. They use the new UL-mandated repeating 85-decibel alarm horn pattern. This unit is approved for sale in Oregon after new revisions on law HB2586.

Each package includes one smoke alarm, one 9-volt battery, and a user's manual. Keep your family safe with this hardwired smoke alarm, as the battery backup ensures constant monitoring, even during power failures.
