Get to know this product.

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

Nest Protect has been redesigned from the inside out. It has a Split-Spectrum Sensor, tests itself automatically and lasts up to a decade. It’s also the first home alarm you can hush from your phone without any extra hardware required. And it tells you what’s wrong and can even alert your phone.

The smoke alarm other alarms look up to.

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.

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 2 a.m. 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.

Safety Checkup

Tests 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 password. You can use your phone to hush and test alarms. And you'll all get alerts on your phone if something's wrong at home.

Sees both fast and slow burning fires.

The foam and particle board in much of today’s furniture make fires burn faster. Technology should keep up. The Split-Spectrum Sensor uses two wavelengths of light to detect smoke from both fast-burning and smoldering fires.

In the 1970s, it would take about 30 minutes for a fire to take over a room. Today, it can take less than 5.

10-year CO sensor.

Carbon monoxide is poisonous but you can’t see it or smell it. That’s why Nest Protect has the most accurate type of carbon monoxide sensor available. We also improved our carbon monoxide sensing algorithm. And we’ll keep working to make it better and better because people depend on it.

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.

Lights your way

If you need a glass of milk in the middle of the night, Nest Protect lights up as you walk underneath it. Pathlight is one of our customers’ favorite 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.

Count sheep, not chirps.

No one should be woken up by a low-battery chirp at 2 a.m. When you turn off the lights, look for a quick green glow. That’s our Nightly Promise. It means all your Nest Protects have tested themselves, the batteries are good, and there won’t be any chirps. Sweet dreams.

Look for the light ring.

In addition to its voice, Nest Protect uses colors to communicate. And we gave the new Nest Protect a brighter light ring so it’s easier to see in an emergency and better at helping you see things in the dark.

Nightly Promise

Nest Protect constantly monitors its sensors and batteries. A quick green glow when you turn out the lights says everything's working.

Pathlight

When you walk under Nest Protect at night, it will light your way. You can choose different light levels or turn Pathlight off entirely in the app.

Heads-Up

If there's only a little smoke, like you've burned toast, it will glow yellow and give you a friendly Heads-Up so you check on things.

Emergency

When smoke or carbon monoxide reaches dangerous levels, Nest Protect sounds the alarm, pulses res, and tells you where the emergency is.

This is going to be easy.

You can set up your Nest Protect in just minutes using your iPhone, iPad, or Android device. And Nest Protect is now even easier to install. But if you need help, we have customer support with real humans to answer your questions.
