Nest Protect: 2nd Gen Smoke + CO Alarm
At a glance
The next generation smoke and CO alarm that thinks, speaks, and alerts you on your phone.
You’ll know, from anywhere
Nest Protect alerts your phone¹ when something’s wrong at home. You’ll get a message if the alarm goes off, if the batteries start to run low, or if a sensor isn’t working.
It tells you what and where the danger is
The new Split-Spectrum Sensor looks for both fast and slow-burning fires. It also has a 10-year CO sensor so it can tell you where poisonous, invisible CO is hiding. And all your Nest Protects speak up at the same time to tell you what’s wrong and where the problem is.
Hush your alarm from your phone
Just burned the toast? Or left the popcorn in the microwave too long? When there’s only a little smoke, you can hush the new Nest Protect using the Nest app.¹
It’s thoughtful, not annoying
Nest Protect tests itself over 400 times a day and you can check the status in the Nest app. It also has Steam Check so a relaxing shower doesn’t cause your alarm to yell at you. And as you walk underneath it at night, Pathlight lights your way.
If Nest Protect sounds the alarm, it tells your Nest Thermostat to turn off the furnace. It’s the most common source of carbon monoxide leaks and can spread smoke around the house if there’s a fire. Your Nest Cam will also record a clip while the alarm is going off so you can see what happened.
More than one color. To tell you more than one thing.
The Nest Protect light ring can display different colors depending on what’s going on.
