Product Overview

Detects Smoke and Carbon Monoxide

The First Alert Combination Smoke and Carbon Monoxide Alarm detects two threats, smoke and carbon monoxide, in a single device. This 2-in-1 hardwired alarm has lights on the face of the alarm to let you know which threat has been detected.

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 combination CO and smoke detectors within a single-family residence. Once one alarm is triggered, all connected CO and smoke alarms will sound. The latching alarm indicator on the hardwired CO and smoke alarm automatically identifies which detector initiated the alarm – even after the conditions that set off the alarm have subsided.

Easy to Install and Maintain

The First Alert Hardwired Combination Smoke and Carbon Monoxide Alarm integrates with existing wiring and features the easy adapter plug, which makes installing the detector quick and easy. The side-load backup battery compartment makes changing the 9-volt battery simple. Tamper-resistant locking pins prevent unauthorized disabling of the hardwired CO and smoke alarm. Plus, it has a test/silence button for quick and easy testing.
