The First Alert SC9120BA Hardwired Combination Smoke and Carbon Monoxide Alarm uses an electrochemical CO sensing technology and Ionization sensor for smoke detection. It includes a 9V battery for continued function in the event of a power outage. 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. Its latching alarm indicator automatically identifies which unit initiated the alarm. Even after the conditions that set off the alarm have subsided. Designed to meet the latest construction requirements, the First Alert Combination Smoke and Carbon Monoxide Alarm detects two threats, smoke and carbon monoxide. Lights on the face of the alarm tell you what the threat is, and false alarms can be silenced with a single button.
