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

Google Nest Protect detects fast-burning fires, slow-smoldering fires, and carbon monoxide. It provides voice alerts indicating the type and location of the issue. The device offers a Heads-Up alert before sounding the alarm, which can be silenced via your phone. If you're away, it sends notifications to your phone if the alarm triggers or batteries are low. Nest Protect self-tests over 400 times daily, displaying a green glow to confirm functionality when you turn off the lights. It offers protection for up to 10 years.
