How to Install First Alert 9120LBL Hardwired Smoke 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.
