12 Pack Bundle of First Alert BRK Brands Hardwired Combo Smoke & Carbon Monoxide Alarm with 10-Year Sealed Battery Backup, SC9120LBL
Hardwired Combo Smoke & Carbon Monoxide Alarm w/ Battery Backup
The First Alert SC9120LBL Hardwired Combination Smoke/CO Alarm connects directly to your home electrical system. In the event of a power outage, the smoke/CO alarm is equipped with a 10 year lithium battery-backup. Integrating a Smart Technology system will reduce the likelihood of nuisance alarms triggering. A Latching Alarm Indication will remember which unit initiated an alarm. The perfect mount system features a gasketless base and a mounting bracket that keeps the alarm secure over a wide rotation range to allow for true alignment. Under normal conditions, you should not have to replace the battery for the life of the alarm.
Detects Smoke and Carbon Monoxide
Designed to meet the latest construction requirements, the First Alert Combination Smoke and Carbon Monoxide Alarm detects two threats: smoke and carbon monoxide. Lights on the face of the alarm will tell you what the threat is, and false alarms can be silenced with a single button.
Intelligent Sensing Technology Minimizes False Alarms
People sometimes disable a fire detector when it goes off due to cooking smoke or steam, even though in doing so they endanger themselves and their loved ones. Intelligent Sensing Technology is designed to distinguish between real fires and nuisances. This reduces the likelihood of false alarms significantly.
10-Year Lithium Battery Backup
The First Alert SC9120LBL Hardwired Combo Smoke and CO 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.
Connect to Other Alarms for Greater Coverage
This hardwired combination smoke and carbon monoxide detector can be connected to other compatible BRK or First Alert CO smoke detectors within a single-family residence. Once one alarm is triggered, all connected CO smoke alarms will sound. The latching alarm indicator on the CO smoke alarm automatically identifies which unit initiated the alarm–even after the conditions that set off the alarm have subsided.
Easy to Install and Maintain
The First Alert Combination Smoke and Carbon Monoxide Alarm integrates with existing wiring and features a universal mounting bracket that makes installing the unit quick and easy. Connection to AC power is simple with a Quick Connect wiring harness.

How to Install First Alert SC9120LBL Hardwired Combo Smoke & Carbon Monoxide Alarms:
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:
- 120V household electrical circuit (unswitched 120VAC)
- Standard wiring junction box to a 4 in. (10 cm) size, on either the ceiling or wall
- Selecting an appropriate location to install your smoke and carbon monoxide alarms (see below guidelines for additional information):
- When installing an alarm on the wall, the top edge of an alarm should be placed between 4 in. (100 mm) and 12 in. (300 mm) from the wall/ceiling line.
- When installing an alarm on the ceiling, place the alarm as close to the center as possible.
- In either case, install the alarm at least 4 in. (100 mm) from where the wall and ceiling meet.

Connecting First Alert Hardwired Alarms to 120V Wiring
To begin, turn off power at the junction box and connect your alarm to the building's electrical wiring.
- Locate the junction box and turn off power
- Remove the power connector from the new alarm's packaging
- Using wire nuts, attach the hot (black), neutral (white), and interconnect (orange) wires
|Attach to black wire on power connector|
|Attach to white wire on power connector|
Standalone (single-station) alarm: This wire is not needed; tuck the orange wire into the junction box.
Mounting First Alert Hardwired Alarms
- Secure the mounting bracket to the ceiling or wall using screws (included in the package)
- Insert the power connector into the plug on the back of your alarm
- Tuck any hanging wires into the junction box
- Position the base of the alarm onto the bracket and turn it clockwise until it's secured
- Remove the pull-tab to activate the backup battery
Installing Additional and/or Interconnecting First Alert Hardwired 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.

If you have any doubts or reservations about these interconnect requirements, please contact an experienced electrician to install your wiring and hardwired alarms.
Restoring Power and Testing 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.
