BRK 120V AC Smoke Alarm with battery back-up - 9120BA

The BRK 9120BA ionization smoke detector is designed to be hardwired to your building's 120V power source and can be interconnected with up to 12 BRK or American Sensors smoke alarms, and up to 6 smoke/co combination alarms so all units will go in to alarm if any single unit is triggered.  It also features a 9V battery backup so it continues to function if your building power fails.

This unit is cross listed to be compatible with American Sensors SA360, SA379, COS2010 units in mixed installations.  When replacing an older model, the wiring connector and mounting bracket will need to be replaced with the ones included in the new detector package.
