Enhance your household's fire safety and enjoy greater peace of mind with the First Alert SA9120BPCN Hardwired Smoke Alarm with Adapter Plugs. Equipped with an ionization sensor, this 120-volt hardwired smoke alarm reliably detects smoke from fast-flaming fires and alerts you with an 85-decibel alarm. Included adapter plugs eliminate the need for re-wiring during installation, while a backup battery helps keep the unit running in case of a power outage. Designed to maximize accessibility and ease of use, this hardwired smoke detector features a single button that allows you to test and silence the alarm. And thanks to the universal mounting bracket, this smoke alarm is easy to install.
Ionization Sensor Reliably Detects Flaming Fires
The First Alert SA9120BPCN Hardwired Smoke Alarm with Adapter Plugs comes equipped with an ultra-reliable 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.
Adapters Included for Easy Installation
To facilitate hassle-free installation, this smoke alarm comes with adapter plugs that eliminate the need for rewiring if you are replacing an existing, non-First Alert branded detector. The universal mounting bracket further eases installation and covers up drywall cutouts, while tamper-resistant locking pins keep the alarm secure.
Battery Backup for Detection during a Power Outage
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 detector comes with a 9-volt battery and features a pivoting, easy-to-access battery drawer that allows you to replace the battery without dismounting the alarm.
Works in Tandem with Other First Alert Alarms
In addition to functioning independently, this smoke alarm can also integrate with up to 12 other First Alert or BRK hardwired alarms for coverage of larger spaces. If one smoke alarm in the series is triggered, they will all sound. The alarm features a latching indicator to identify which unit triggered the alarm, alerting you to the area of danger.
The First Alert SA9120BPCN 120-Volt AC Smoke Alarm meets UL standards and features a 10 year limited warranty.

Reviewer: Richard Euhus
Purchased one these detectors a year ago to replace an old 20+ years faulty detector. Works well and it immediately sensed a smoking pan on the stove. Bought this one to replace an equally old detector upstairs.

First Alert, the #1 in Alarm Technology! - 10/30/2017
Reviewer: Terry J. Schultz
Have always used First Alert, when Installing Alarms. This order was a Replacement for Smoke Detectors that were installed when our House was built. Of course I chose First Alert to replace the originals, when you have the Best Available, why would I consider any other Detector?!

Reviewer: Donnette Plunkett
Ordered these as replacements for 11 year old units that were installed when our house was built that had gone bad. Installation could not have been easier using the adapter plugs! Did have to switch out the base attachment as well, but that too was very simple to do.
