The First Alert 9120LBL Hardwired Interconnected Smoke Alarm with Lithium Battery-Backup is a great choice when it comes to affordable smoke alarms. In the event of a power outage, this smoke alarm is equipped with a 10 year lithium battery back-up.
Ionization Sensor Reliably Detects Flaming Fires
The First Alert 9120LBL Hardwired Smoke Alarm with Battery Backup 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. This smoke alarm also implements Smart Technology to drastically reduce the number of nuisance alarms triggered.
Gasket-less for Easy Installation
To facilitate hassle-free installation, this smoke alarm features a perfect mount system that includes a base and a mounting bracket. This keeps the alarm secure over a wide rotation range that allows for true alignment.
Latching Alarm Indication
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. It 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 alarm features a latching indicator to identify which unit triggered the alarm, alerting you to the area of danger.
10-Year Lithium Battery Backup
The First Alert 9120LBL Hardwired Interconnected Smoke Alarm features a built-in 10-year lithium battery backup that provides continuous power for the life of the detector. An end-of-life timer lets you know when the device should be replaced.

In this guide, we'll be showing you how to install First Alert Hardwired Smoke and Carbon Monoxide Alarms. Here are a few items you'll need before starting the installation process: Needle-nose pliers or utility knife, screwdriver, wire stripper, wire nuts and a ladder.
Hardwired Smoke or Carbon Monoxide Alarm Requirements:
To begin, turn off power at the junction box and connect your alarm to the building's electrical wiring.
Black wire (hot) |
Attach to black wire on power connector |
White wire (neutral) |
Attach to white wire on power connector |
Orange wire (interconnect) |
Standalone (single-station) alarm: This wire is not needed; tuck the orange wire into the junction box. Interconnected alarms:
|
If you are installing more smoke or carbon monoxide alarms, you'll want to repeat the process throughout the building. Interconnected smoke and co alarms must meet all requirements:
The same fuse or circuit breaker must power all interconnected alarms.
Up to 18 compatible detectors can interconnect, with a limit of 12 smoke alarms.
The total length of wire interconnecting the alarms should be less than 1,000 ft. (300 meters). This type of wire is commonly available at hardware and electrical supply stores.
All wiring must conform to all local electrical codes and NFPA 70 (NEC). Refer to NFPA 72, NFPA 101, and your local building code for more information.
Interconnect wiring diagram:
If you have any doubts or reservations about these interconnect requirements, please contact an experienced electrician to install your wiring and hardwired alarms.
Once you've installed your hardwired alarms, you'll want to restore power to the junction box. Under regular operation, the power indicator light on the alarm will shine/blink to indicate that it is receiving AC power.
Here's how you can test standalone or interconnected alarms:
Standalone Alarms: Press and hold the Test/Silence button until the unit triggers an alarm.
Interconnected Alarms: Press and hold the Test/Silence button until the first unit triggers an alarm. All interconnected detectors should sound off. Repeat this process to test each alarm in the interconnected series.

Replacements Smoke Alarms
Reviewed: 02/18/2021 by RONALD CHRISTOFFERS
Well, I will say that changing out the old with the new was very easy. We will up date you next year if I have to change the battery in any of the new ones. The old smoke alarms were 15 years old and look similar to the new ones, I didn't need to change the bases, it was a plug play procedure. Took about 15 minutes to change out seven units.

Electrician installed and I'm happy and relieved they are in. My fire department said to replace every 10 years. That's good advice which I will follow. So in 10 years I will be back for more First Alert Smoke Alarms.
