The First Alert Battery-Powered Combination Smoke and Carbon Monoxide Detector delivers reliable dual-threat detection in a compact, easy-to-install unit. Designed for whole-home safety coverage, this alarm detects both smoke from fire and the invisible, odorless threat of carbon monoxide gas, alerting occupants with a loud audible alarm.

Powered by replaceable batteries, the detector requires no hardwiring and can be mounted on ceilings or walls in any room of the home. The combination design eliminates the need for separate smoke and CO alarms, simplifying installation and maintenance. A test/silence button allows for regular function checks and quick alarm silencing after cooking or other non-emergency events.

First Alert is one of the most trusted brands in home safety, with a long history of manufacturing UL-listed alarms that meet rigorous industry standards. This model is ideal for bedrooms, hallways, and living areas where both fire and CO risks must be monitored.
