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.
First Alert Smoke Alarm 9120B
Recommended replacement for the following obsolete models:
BRK 4120B
BRK 4120SB
BRK 86RAC
First Alert SA4120B

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.

Easy to Install
Just installed the 9120B Smoke Alarm after painting the hallway celling. This model was the replacement for the smoke alarm that was installed in the celling since 1992, it was really time to update it and it was very easy to do. The alarm looks great and it appears to be doing what it suppose to do, monitoring for a fire. I like it, no false alarms and I think it will last 10 years with no problem.

Replacing 20 year old Smoke Detestors
After determining our battery backup, First Alert Smoke Detectors were installed in 2001, putting them well beyond the expected 10-year lifetime. After searching the web, I hit on the First Alert Store. The price was acceptable, so I Ordered seven 9120Bs. They arrived in less than a week from the order date. The only concern with the replacements was that the mounting brackets were of a larger diameter than the originals. That required that not only the body but the bracket needed to be replaced. Everything required was provided, and even for an old guy, it went pretty fast.

Switching Out Old Smoke Alarms for New Ones
The process from beginning to end was effortless. I ordered a box of 12 smoke alarms to replace the 20-year old smoke alarms in my home. They arrived quickly and in excellent shape. My prior research revealed these new alarms were compatible replacements for my old ones. It literally took me less than 45 minutes to switch out all the old ones with new ones. I couldn't believe how easy it was to do. I almost hired someone to do it for me and am glad I decided to do it myself. Saved $$ with DIY. Bottom line: I've very pleased with my purchase and would recommend this product and vendor to family and friends.

Had to replace the smoke detectors that had been in place since 87 when house was built after they failed to go off when we forgot to turn off a pot on the stove and the house filled with smoke. Opened up one of the old ones and found it was from First Alert so I went on their website and found a great deal on First Alert 9120B Hardwired Smoke Alarm with Battery Backup. Turned off the power and had all 3 swapped out in 15 minutes. Haven't had any event yet that would cause an alert, but they all joined together and seem to be operating as designed. Very happy with my purchase.

This was an easy swap over from an older First Alert model that is no longer available. The existing detector kept chirping even with a new battery. The existing base was not compatible with the new detector, but the new base fit perfect. The existing wiring and plug was a match, so I did not have to rewire anything either. When I tested the unit, it also triggered the other units in the house like it's supposed to. I will be replacing all the old smoke detectors with this unit.

Quick and easy! It will be nicer though if the functionality of its operations can be either AC or AC plus battery.

Then again, if the regulations call for the mandatory battery backup to exist, my preference would be invalid.

So glad that I was able to use existing cabling for the SC9120LBL, as well as the smoke only model. Install for all 7 locations was under 30minutes.

I needed to replace outdated and no longer supported hardwired smoke alarms and was initially worried about compatibility. While the mounting plate was a bit different it lined up nicely with previous screw mounts and these were a breeze to install, test and be operational. It took longer to get the ladder set up...

Works fine, but supplied 9v battery is a cheap heavy duty not alkaline. it's ok though as the hardwire supplies the power, not the battery.

Easy installation for replacement
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.

Amazons Price Gouging
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!!

SInce I was replacing identical units I did not need to mount a new mounting plate or do any new wiring.

Most BORING installation of all time
I was replacing a faulty smoke detector in my house, and was disappointed with how boring this was to replace. Loosen two screws on old mounting plate, remove mount. Add new mounting plate, tighten screws. Remove plastic strip to engage battery, plug in detector wtih existing wire, twist detector into mount. Press test button, verify it works. Done. Yawn. Easiest upgrade/replacement of anything in any house I have ever owned. No multiple trips to the hardware store, modification of anything required, 1 tool not a big hammer, no swearing, blood, or fire. Would buy again.

Ordering was very simple and the service was fast. Was able to replace my older First Alert smoke alarms eight in all in about 90 minutes. This included replacing the ceiling brackets. Yes, the new smoke alarms were compatible to the old brackets, but for a cleaner look it was easy to replace the old brackets with the new ones. I was very pleased that the smoke alarms came with the 9-volt batteries.

Quick and easy swap out
Replaced an earlier version of this smoke detector. The new detectors used the same hardwire connection as the old one. Just had to replace the base on the junction box and put on the new smoke head. Easy! and my house is up to date for another 10 years. Great service and shipping from the First Alert online store. If you need First Alert products, just go to the online store. They will have what you want.

No Problems
No issues. I tried calling on the weekend, but Sales Desk apparently is only open on weekdays. I called the service number and, since the smoke detector that I was replacing was over ten years old, the service desk helped me to ID the proper replacement model. I then went and ordered it online. Product arrived less than a week later. All good.

Built to last
After nearly 8 years it was time to replace my old First Alert detectors. I was surprised the old ones would last this long but am sold on First Alert.

Replaced 9 old 9120s with 9 new ones. All of them all worked perfectly. Only small hassle was mounting ring was a different diameter than the old ones but that is an easy problem to get past... 2 screws, half twist and it's done.

Well I installed a system of 9120b interconnected smoke alarms and they worked better than the older product, a brk smoke detector which had outlived its usefulness. I recommend you use First Alert/BRK products

Smoke Detector
This smoke detector is better then the Kidde product I used to have, when I sometimes over cook foods this alarm goes off quickly, the older Kidde product took a while to activate. I'd recommend this smoke detector to anyone who is looking to upgrade their units.
