Hardwired Smoke Alarm with Battery Backup

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.

Great Smoke Alarms

Reviewed: 05/25/2020 by Barbara Angelucci

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.

Reviewed: 03/13/2020 by Thomas Long

I purchased 8 First Alert 9120LBL units. In less than I hour, I replaced all the older units, First Alert 9120B. The reason this was easy is that you still use the same electrical connector and the same mounting bracket. Thank you for doing both these things. I was worried it would take a lot more time and so had been putting replacement off. I suggest you advertise how easy you have made this replacement -- it might save some lives. Next I want to extend this wired system with wireless additions. I would like to see detailed into on how to do that with particular units I have installed.

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.

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.

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.

Easy Upgrade

Reviewed: 07/07/2018 by James Frost

I have a newer house, which the builder equipped with the 9v power backup version of these alarms. I hated changing all those batteries every six months. And if I forgot to do it and one started chirping at 2AM from a low battery, I had to figure out which one it was, which isn't always easy. When those older detectors finally reached the end of their lives, I decided to spend a little more on the hardwired version that also comes with a 10 year battery. So glad I did. These were plug and play compatible with the 10 year old BRK/First Alert wires and even the mounting brackets are still the same. It was literally remove/unplug the old one, plug in the new one, twist it into place and pull the plastic tab that kicks on the backup battery. I replaced all 10 detectors in less than an hour. And no more battery changes or 2AM beeping.

I was hoping to find a direct replacement for my current hardwired 9V Alarms. I e-mailed First Alert and received a fast response. I gave them the model number and they suggested these as a direct replacement. Bingo! These fit my already installed brackets and wiring and now I have 10 year batteries. No more climbing a ladder every 6 months to change the battery.

Q: What is the proper placement of smoke alarms?

A: It is important that you have the proper placement for your smoke alarms. Install your alarms at least 20 feet from appliances like furnaces and ovens, which produce combustion particles. Alarms should be at least 10 feet from high humidity areas like showers and laundry rooms, and at least 3 feet from heat/AC vents. Be sure to install a smoke alarm in each bedroom, one at the top of each stairwell, and one on every level.

Q: Why doesn't my smoke alarm sound when I push the test button?

A: It is important that you frequently test your smoke alarms. When you are testing your smoke alarm, there are a number of reasons why the alarm might not sound:

You may not be holding the test button down long enough. Try holding it down for up to 10 seconds (20 seconds on photoelectric models) .
Your battery may not be installed properly or snapped all the way in place. Even if the alarm sounded briefly when the battery touched the terminals, you still need to make sure it is snapped securely in place. If the battery is loose, in cannot power the smoke alarm properly. After installing new batteries, be sure to test your smoke detector.
Your AC power may not be on. AC and AC/DC units will have a power indicator light (red or green) that shines continuously when they are receiving electrical power.
If you have a 10-Year model, the smoke alarm may not have been properly activated. If the tab broke away before the alarm was activated, you can use a toothpick to move the switch over to test the alarm.

Q: Why does my smoke alarm go off when I install a battery or turn on the AC power?

A: It is normal for smoke alarms to go off and sound briefly (up to 5-10 seconds) when you install a new battery or when they are powered up. If the alarm continues to go off and no smoke is present, the cause may be one of the following:

There may be insufficient battery power, try new batteries.
Problems with voltage or insufficient electrical power (brown out) may cause a continuous weak sounding alarm. For AC or AC/DC models, temporarily disconnect power at the service panel until the brown out is over. If you do not restore the AC power, your smoke alarms cannot warn you of a fire.
Incompatible warning device. If an incompatible alarm or auxiliary device is linked into a series of AC or AC/DC smoke alarms it may cause the system inadvertently go off.

Q: I lost my First Alert smoke alarm owner's manual. How can I get a new one?

A: First Alert smoke alarm owner's manuals are available online for download at no cost. Find your alarm in our Smoke Alarms section.

Q: Why does the National Fire Protection Association (NFPA) recommend that home smoke alarms be replaced after 10 years?

A: Smoke alarms have a limited life. Although each smoke alarm and all of its parts have passed many stringent tests and are designed to be as reliable as possible, any of these parts could fail over time. Therefore, you must test the devices weekly. The unit should be replaced immediately if it is not operating properly. The performance of smoke alarms older than 10 years is simply not reliable. To ensure your family's safety, all carbon monoxide and smoke/CO combination alarms need to be replaced every 5-7 years. All smoke alarms need to be replaced every 10 years.
