Designed to help promote household safety, the First Alert 9120B Hardwired Smoke Alarm with Battery Backup can provide a vital early warning of fire. This hardwired smoke detector uses an ionization smoke sensor to reliably detect smoke from hot, fast-flaming fires.
Ionization Sensor Reliably Detects Flaming Fires
The First Alert 9120B 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.
Gasket-less for Easy Installation
To facilitate hassle-free installation, this smoke alarm features a streamlined mounting system with a gasket-less base. The mounting bracket keeps the alarm secure over a wide rotation range while maintaining perfect alignment. The alarm also comes with a dust cover to keep the unit clean during construction. AC-powered smoke alarms must be installed in accordance with all local electrical codes.
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 unit 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. 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.

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.
We make it as easy as possible to ensure you get the lowest prices available:

Great inexpensive smoke alarm!
Reviewed: 04/20/2021 by Stephen L
I recently bought a home that still had the original Kidde/FireX smoke detectors from 2002! I ordered these First Alert 9120B because I liked the value and trusted the brand. Installation went smoothly without any issues. I had to remove the existing wire nuts to replace the wire adapter going from Kidde to First Alert. That took a little more time but wasn't too difficult. These 9120B have worked great so far and no issues with false alarms at all. I would recommend these to friends and family.

I recently installed 6 of these units in our home to replace 10-year old first alert detectors. The old detectors worked flawlessly for 10 years, but had reached the end of their expected life. Those old detectors in turn replaced the 6 original units in our house built in 1999. I was pleased to find that the wire harnesses and detector mountings are still the same for this model. All I had to do was unplug the old units, and remove them, simply plug in the new units to the harnesses and twist them in place and check their operation. It took about 45 minutes to do the entire job slowly and deliberately, and the new units are operating perfectly.

I ordered three 9120B ionization smoke alarms from firstalertstore.com. They were shipped very quickly by USPS Priority Mail. The items were fresh stock, manufactured only two months earlier. I ordered an additional three First Alert Photoelectric smoke alarms 7010B from Amazon because their price was lower than the firstalertstore.com. These were very slow in arriving and were made over two years ago. First Alert has told me that even though these are over two years old, if they have never been activated, their useful service life will not be affected. I hope so. Otherwise, next time I will order all my replacements directly from First Alert.
So far so good.

Didn't realize until lately that smoke alarms should be replaced every 10 years of so. Our hard wired alarms were 26 years old so I contacted the First Alert Store to purchase replacements and wiring adapters.

Amazons Price Gouging
Reviewed: 03/24/2020 by S Thomas Church Jr
I needed to replace an old First Alert hardwired Smoke Alarm that was still working after 30 years in my finished basement. It was discolored so I called First Alert and was given the exact replacement. Once I had the model number I tried to find it on Amazon but they showed multiple versions so I called First Alert again and the tech asked me how much did it cost and he was amazed that it cost 4 times what First Alert Store offered on line. I immediately ordered the replacement with free shipping and saved over $30 versus Amazons price. I recommend that anyone that is planning on purchasing First Alert Smoke alarms that they call the First Alert on-line store always. Plus I had on-line excellent technical help on how to uninstall and install the smoke alarm. This is not the first time that I realized that Amazon practices price gouging, in fact, I am awaiting an investigation from Amazon as to why a physicians practice offers an identical item for 10% higher price. Buyer Beware!!

I replaced a First Alert alarm like the one I had. For some reason it just kept chirping and new batteries made no difference. After checking several local retail stores and not finding an alarm like the one I had, I found the exact model online at First Alert. The order process was fairly easy and the alarm actually arrived ahead of the anticipated delivery time. The alarm was exactly like the one I had. I am totally non technical and would not attempt the installation so I had a friend install it and apparently the process was fairly easy and the alarm immediately worked when installed. Am very pleased to have been able to replaced an alarm with the exact model I already had. Very pleased with the entire process from ordering to receipt to installation and am quite pleased with the alarm.

I decided to replace 5 of my First Alert Smoke Detectors because they have been used in my home for about 13 years. I contacted First Alert to obtain the correct replacement model for what I currently had. I wanted to make sure the new Model would just plug into the existing hard wire models. I was assured they would plug in the the hard wires without any problem. This was the case and all 5 First Alert Smoke Detectors are installed and working as required.
