Google Nest Protect 2nd Gen Wired Smoke & CO Alarm with Voice Alerts & Mobile Notifications

Google Nest Protect is a smart smoke and carbon monoxide detector. It detects fast-burning and smoldering fires, as well as invisible carbon monoxide. The device provides voice alerts to identify the issue and location. A Heads-Up feature warns you before sounding an alarm, and it can be silenced via your phone. If you’re away, it sends alerts to your phone for alarms or low battery. The device self-tests over 400 times daily, displaying a green light to confirm functionality when you turn off the lights. It offers protection for up to 10 years.
