Main Features of the Kidde Hardwired Detector
Dual Smoke and Carbon Monoxide Detection
This unit combines smoke detection and carbon monoxide monitoring into one compact device. Instead of installing two separate systems, homeowners can simplify protection while maintaining strong safety coverage throughout the home.
