Product Features

Smart, Sophisticated Smoke and CO Detection

Offering state-of-the-art smoke and carbon monoxide detection, app connectivity, and endless convenient features, Google Nest Protect is the ultimate smoke alarm solution.

Senses Both Fast and Slow Burning Fires

Google Nest Protect uses an advanced Split-Spectrum Sensor to detect a wide range of smoke events, including slow and fast fires.

It works by using two wavelengths of light: one looks for large particles created by slow, smoldering fires while the other looks for smaller particles created by fast, flaming fires.

Accurate CO Detection for 10 Years

Google Nest Protect uses the most accurate type of carbon monoxide sensor available - electrochemical. It also lasts up to a decade.

Friendly Human Voice

Google Nest uses a friendly human voice for early warnings such as a bit of smoke. If you have more than one Google Nest Protect Alarm installed, they all speak.

App to Send Alerts and Notifications

Connect with the Google Nest app to get alerts and safety notifications sent to your phone:

  • Alarm alerts (if you're away)
  • Low battery alerts (instead of hearing annoying beeps)
  • Safety checkup reports (so you know everything is in working order)

You can also use the app to hush your alarm with your phone.

Tests Itself

Google Nest Protect checks its batteries and sensors over 400 times a day so you don't have to remember to do it. It also uses Sound Check to quietly test its speaker and horn once a month.

Lights Your Way at Night

Google Nest Protect features a bright ring of light that illuminates as you walk underneath it, especially convenient and helpful at night.

Knows the Difference Between Steam and Smoke

Google Nest Protect is the only alarm that uses custom algorithms and a humidity sensor to tell the difference between steam and smoke.

What the Lights Mean

In addition to voice, Google Nest Protect uses its light ring to communicate. Here's what all the colors mean:

  • Green (Nightly Promise): A quick green glow when you turn out the lights means everything is working
  • White (Pathlight):  A white ring lights your way when you walk underneath (can be controlled or turned off in the app)
  • Yellow (Heads Up): Yellow means there's a little bit of smoke, go check on things
  • Red (Emergency): When smoke or carbon monoxide reaches dangerous levels, Google Nest sounds the alarm, pulses red, and tells you where the danger is


You'll need the following to enjoy all of Google Nest Protect's features:

  • Wi-Fi connection (802.11b/g/n (2.4GHz))
  • Phone or tablet with iOS 8 or later, or Android 4 or later
