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.

Cheaper than buying it at the box store

Works as expected. Have not had any issues with it yet. Unlike the ones at the stores, this does not come with the adapters to fit this where your old one was. You will have to remove the old connection and wire this new one in. There could be worse things.

These replace the ones that were already in the house. These were easy to install and even came with a back-up battery which my old ones didn't have.

Great Improvement in Already good Smoke Detectors
Reviewed: 08/29/2019 by Elliot A Clark
Each year I dreaded changing the 9V backup battery in my old 9120B BRK/First Alert smoke detectors- I don't like having to use ladders. But I did it I have 5 in my house. When the time came to replace the detectors, I was thrilled to be able to install detectors with battery backup that equals the detector life itself. Replacing the detectors in already existing mounts is pretty easy- easier than replacing the backup battery each year.

First time I bought from this manufacturer the pricing was good, selection was good and the product was delivered quickly.
More than just a smoke alarm

This wired alarm was easy to install to replace the alarm I had. I found an extra bonus because in the dark it projected a light on the floor. Not a bright light but one that looked like a three leaf clover. I am well pleased.
Work great!

These work great and the best part is they are still manufactured and available - A VERY good thing for a wired detector!
Pair of 9120LBL smoke detectors from First Alert Store
Reviewed: 06/17/2019 by GARY HORNYAK
The installation of the two 9120LBL to replace a pair of older model hardwired BRK smoke detectors was easy. More time was spent locating the correct circuit breakers that needed to be turned off. The manufacturing date of the two smoke detectors was may 2019 for an order which was placed in May 2019 - reviews of orders placed with other online stores talked about receiving items who had a manufacturing date indicating the age was up to 2 years old, which is one of the reasons I ordered directly from First Alert Store. My only negative comment is the shipping envelope did not do a great job in protecting the retail boxes, but due to the sturdiness of the smoke detectors they had no shipping damage.

Perfect Upgrade!

These are easy to install to replace the 9-volt units that are not to code any longer.
Saved me $100s
Reviewed: 02/15/2019 by Edward Town
The six hard wired 9120s in my condo failed. No surprise, they were 5 yrs old. An electrician said he'd replace them with 10 yr battery models for $450. Then I found these they used the same wiring connectors and I installed all 6 in less than a half hour. I saved over $300. I like my electrician but not that much. Thanks First Alert.
