Hardwired Smoke and Carbon Monoxide Alarm with Battery Backup
The First Alert BRK SC9120BA Hardwired Combination Smoke and Carbon Monoxide Alarm uses an electrochemical CO sensing technology and Ionization sensor for smoke detection. It includes a 9-volt battery for continued function in the event of a power outage, and it features a test/silence button, tamper-resistant locking brackets, and a universal mounting bracket. This CO smoke detector can be connected to other compatible BRK and First Alert hardwired smoke and carbon monoxide detectors.
