The BRK hardwired smoke alarm with battery backup comes equipped with an ionization sensor to 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
To facilitate hassle-free installation, this fire and smoke alarm features a streamlined-mounting system with a gasket-less base
The-mounting bracket keeps the detector secure over a wide rotation range while maintaining perfect alignment
The ionization fire alarm also comes with a dust cover to keep the unit clean during construction
AC-powered smoke alarms must be installed in accordance with all local electrical codes
This smoke alarm is designed for hardwired installation, but it also features a battery backup that helps ensure continued functionality in the event of a power outage
The smoke and fire detector comes with a 9 V battery and features a pivoting, easy to access battery drawer that allows you to replace the battery without dismounting the hardwired alarm
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 alarm in the series is triggered, they will all sound
The fire alarm features a latching indicator to identify which unit triggered the alarm, alerting you to the area of danger
