2026 NEW Google Nest Protect 2nd generation smoke and carbon monoxide detector with cable, voice alerts and smartphone notifications

Google Nest Protect detects fast-burning and slow-burning fires, as well as carbon monoxide. It provides voice alerts indicating the type and location of the problem. The device warns you of the alarm, which you can silence via your smartphone. If you're not home, you'll receive notifications on your smartphone as soon as the alarm is triggered or the battery is low. Nest Protect performs over 400 self-tests daily and displays a green light when the lights are turned off to confirm it's working properly. It offers protection for up to 10 years.
