Nest Smoke Alarms

NEST Protect Smoke & CO2 Alarm

Thinks, before it speaks.

Nest Protect has a friendly human voice that gives you an early warning. That way you can handle burning toast before it becomes a burning toaster.

Tells you where the danger is.

And when one speaks, they all speak. So the alarm in your bedroom can tell you there’s smoke downstairs.

Tests itself

You’re supposed to test smoke alarms monthly. But 9 out of 10 people don’t. So Nest Protect checks its batteries and sensors over 400 times a day. And it’s the first alarm that uses Sound Check to quietly test its speaker and horn once a month.

It’s time to expect more from your smoke alarm.

Nest Smoke & CO2 Detector

Lights your way

If you need a glass of milk in the middle of the night, the new Nest Protect lights up as you walk underneath it. Pathlight is one of our customers’ favourite features so we made it better and brighter.

​

Steam is not smoke

Has your alarm ever yelled at you for taking a shower? Nest Protect is the only alarm with Steam Check. It uses custom algorithms and a humidity sensor to look for steam, so you can enjoy a nice, quiet shower.

Nest Protect Shefield

App Silence

Hush alarms with your phone, not your dish towel. If everything’s under control and there’s only a little smoke, quiet down the alarm from the Nest app.
 

Phone alerts

Everyone in your family can know what’s going on, from anywhere. When something’s wrong, Nest Protect sends everyone an alert in case no one’s home.
 

No chirps

Tired of getting woken up at 2am by your smoke alarm? Long before it has to chirp, Nest Protect tells you its batteries are running low with a message on your phone. And don’t worry, that won’t happen for years.
 

Safety Checkup

Test all your alarms with a tap. And once the test is done, you’ll get a full report.
 

Family Accounts

Everyone in the family can have their own Nest Account. No more sharing a login. You can all use your phone to hush and test alarms. And you’ll all get alerts on your phone if something’s wrong at home.
