The BRK 9120B AC/DC Smoke Alarm has been designed for fast installation, for better performance and to be smarter than ever. Using ionizing sensory technology the 9210B detects fire particles that are invisible sooner than a photoelectric smoke alarm would providing you and your family more security. This AC/DC alarm comes with a 9-V battery backup. You can connect easily to AC power with the unit’s Quick-Connect wiring harness.
The 9120B comes with a latching alarm indicator that will inform you which smoke alarm in your house the alarm originated from saving you time and energy.
The BRK 9120B is easy to install and to maintain. It includes an opening in the mounting bracket which gives you easy access for wiring. There are also keyhole slots on the mounting bracket which removes the need to take out the electrical box screws when installing the 9120B.
The battery can be replaced while unit is still mounted to your wall or ceiling because the battery compartment is on the unit’s side. There are two locking features on the unit which will prevent battery or alarm theft.
The BRK 9120B is listed to UL 217 and comes with a ten year limited warranty.
