Nest Protect Alarm Google Carbon Monoxide Detector White

There’s never been a smoke and CO alarm quite like this. Nest Protect looks for fast-burning fires, smoldering fires, and carbon monoxide. It speaks up when there’s a problem and can send a message to your phone if you’re not at home. And it helps keep you safe and sound for up to a decade. The blue light glows when Nest Protect is active and ready to be connected or tested with a Safety Checkup.
