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 fast-flaming fires and alerts occupants with a loud 85-decibel alarm. Engineered to be hardwired directly into a home's electrical system, the device features a backup battery to ensure continued operation even during power outages.

The smoke alarm's gasketless mount facilitates easy and secure installation, while tamper-resistant locking pins keep the unit in place. A convenient test/silence button allows users to easily check the alarm's functionality and mute false alarms. This smoke detector can be interconnected with up to 12 other compatible First Alert or BRK hardwired alarms, and it includes a latching indicator that identifies the triggering unit.

Introducing the redesigned BRK 9120 series smoke alarms, which have been engineered from the ground up to install faster, perform better, and offer enhanced intelligence. These improvements help reduce nuisance alarms, saving time and money. BRK Electronics smoke alarms are designed for easy installation, maintenance, and long-lasting, virtually maintenance-free service.

The 9120B AC-powered smoke alarm with battery backup includes several key features. The ionization sensor is optimized to detect fast-flaming fires that consume combustible materials rapidly. 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, ensuring that all alarms will sound when smoke is detected.

Power indicators on the alarm identify the unit that initiated the alarm. The latching alarm indicator automatically pinpoints the triggering unit. Smart technology helps reduce nuisance alarms, and a 9-volt battery backup provides peace of mind during power failures. A single test/silence button allows users 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 and a new mounting bracket, enables easy installation and secure positioning over a wide rotation range for optimal alignment. Tamper-resistant mounting bracket locks and a dust cover keep the alarm secure and clean during construction. All BRK Electronics smoke alarms are UL 217 standard-compliant, listed with the California State Fire Marshal, and covered by a 10-year limited warranty.

This First Alert 9120BFF smoke alarm is approved for sale in Oregon after the recent revisions to law HB2586. Ensuring constant monitoring, even during power outages, the hardwired design with battery backup keeps your family safe. Equipped with an ionization sensor and an 85-decibel alarm, this smoke detector reliably detects fast-flaming fires and alerts occupants. For complete home protection, install one on each level and in each bedroom.
