First Alert 9120B Smoke Detector, 6-Pack

This package of six First Alert hardwired smoke alarms is equipped with a 9-volt battery backup, ensuring continued protection in the event of a power failure. The detectors feature an ionization sensor for reliable detection of smoke and fast-flaming fires, as well as a loud, 85-decibel alarm to alert you.

The alarms come with a simple-to-use test/silence button, which allows you to silence any nuisance alarms and test the detector functions. The side-load battery compartment further enhances the ease of use, and the tamper-resistant locking brackets and universal mounting brackets make installation a breeze.

These smoke alarms have been rigorously tested to meet UL standards and emit the T3 pattern, providing comprehensive safety for your home. The latching alarm indicator automatically identifies the unit that initiated the alarm, even after the conditions that set it off have subsided.

The end-of-life signal feature enhances your safety by letting you know when it's time to replace the unit, ensuring your family's continuous protection. These alarms can be connected to other compatible BRK or First Alert smoke detectors within a single-family residence, so that when one alarm is triggered, all connected alarms will sound.

It's important to note that these are hardwired alarms, and you should confirm that the wiring polarity is correct and that all wire nut connections are secure. A loose neutral (white wire) connection within the home junction box could prompt a device malfunction.

First Alert has been the most trusted brand in home safety since launching the first residential smoke alarm in 1958, according to a brand trust survey conducted in February 2018. With this 6-pack of hardwired smoke alarms, you can enjoy faster turnarounds on job sites and the peace of mind that comes with the most trusted alarms in home safety.
