9120B Hardwired Ionization Smoke Alarm With Battery Backup

Product Overview

Ionization Sensor Reliably Detects Flaming Fires

The First Alert Hardwired Smoke Alarm with Battery Backup comes equipped with an ionization sensor to help provide the earliest possible warning of a fast-flaming fire. The sensor is optimized to detect flaming fires, such as those caused by paper, kitchen grease, and other fast-combusting materials.

Hassel-Free Easy Installation

To facilitate hassle-free installation, this fire and smoke detector features a streamlined mounting system with no need to rewire. The mounting bracket keeps the detector secure over a wide rotation range while maintaining perfect alignment. AC-powered smoke alarms must be installed in accordance with all local electrical codes.

Battery Backup for Detection During a Power Outage

This Ionization Smoke Alarm is designed for hardwired installation, but it also features a battery backup that helps ensure continued protection in the event of a power outage. The smoke and fire detector comes with a 9-volt battery and features a pivoting, easy-to-access battery compartment that allows you to replace the battery without dismounting the hardwired detector.

Works in Tandem with Other First Alert Alarms

In addition to functioning independently, this hardwired ionization smoke alarm can also integrate with up to 12 other First Alert or BRK hardwired alarms for coverage of larger spaces. This detector also integrates with up to six other compatible devices, such as bells, horns, and repeaters. If one detector in the series is triggered, they will all sound. The fire alarm features a latching indicator to identify which unit triggered the detector.
