The First Alert Combination Smoke and Carbon Monoxide Alarm integrates with existing wiring and features a universal mounting bracket that makes installing the unit quick and easy. The side-load battery compartment makes changing the 9-volt battery simple. Tamper-resistant locking pins prevent unauthorized disabling of the CO smoke alarm.

Hardwired Combination Smoke/Carbon Monoxide Alarm

The First Alert BRK SC9120B 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. Its latching alarm indicator automatically identifies which unit initiated the alarm–even after the conditions that set off the alarm have subsided.

Detects Smoke and Carbon Monoxide

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.

Connect to Other Alarms for Greater Coverage

This hardwired combination smoke and carbon monoxide detector can be connected to other compatible BRK or First Alert CO smoke detectors within a single-family residence. Once one alarm is triggered, all connected CO smoke alarms will sound. The latching alarm indicator on the CO smoke alarm automatically identifies which unit initiated the alarm–even after the conditions that set off the alarm have subsided.
