Hardwired Smoke Detector with Battery Backup, White, 1-Pack

Introducing the revolutionary BRK 9120 series smoke alarms, which have been redesigned from the ground up. With faster installation, enhanced performance, and smarter features, these smoke alarms from BRK Electronics 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, which helps detect fast-flaming fires that consume combustible materials rapidly. This 120-volt AC smoke detector 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.

To ensure complete protection, the 9120B smoke alarm can be installed on each level of your home and in each bedroom. The single test/silence button allows you to both silence a non-threatening alarm or low-battery warning and test the unit's functionality. The perfect mount system, including a gasketless base for easy installation and a new mounting bracket that keeps the alarm secure over a wide rotation range, ensures a perfect alignment for easy installation.

Designed for enhanced safety, the 9120B smoke alarm features tamper-resistant locking brackets, a dust cover to keep the unit clean during construction, and a 9-volt battery backup to keep the alarm functioning during power outages. The unit also includes smart technology to reduce nuisance alarms, providing peace of mind and saving you time and money.

First Alert, the most trusted brand in home safety since launching the first residential smoke alarm in 1958, has engineered the 9120B smoke alarm to meet the highest standards. Rigorously tested to meet UL standards, this smoke alarm uses the new UL-mandated repeating 85-decibel alarm horn pattern and is approved for sale in Oregon after the new revisions on law HB2586.
