This battery-powered alarm is also easy to install. Because it does not need hardwiring, you can place it where protection is needed. It is a useful choice for bedrooms, hallways, living areas, and other locations in your home.
2-in-1 Smoke & Carbon Monoxide Protection
The First Alert SMCO100 monitors for both smoke and carbon monoxide. First Alert’s Precision Detection technology is designed to provide early warning during a home fire emergency. In addition, it helps reduce unwanted alarms caused by normal cooking.
