About the product
The BRK SC9120BA is a combination smoke detector and carbon monoxide detector designed to be hardwired to 120V electrical power, and can be interconnected with up to 12 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 temporarily.
The SC9120BA is a direct replacement for the American Sensors COS2010 which is no longer available and is 100% compatible with mixed installations of interconnected American Sensors and BRK wired detectors. The SC9120BA can also be used to replace American Sensors SA360 or SA379 style smoke detectors with the benefit of adding Carbon Monoxide detection which is now required by law in most jurisdictions.
Note: If you are replacing COS2010, SA360, SA379 or other older models you will need to install the new wiring harness and bracket that come in the box. See this page for a video showing how to replace the COS2010 or SA360. (For your convenience, the related files section on this page contains a declaration of compatibility from the manufacturer and an installation manual).
