Nest Protect

The smoke alarm that thinks, speaks, and alerts your phone.

The alarm goes off and your mind starts to race.

Where’s the problem?
Is it smoke? CO?
Burned popcorn?

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

The new Nest Protect has been redesigned from the inside out. It has an industrial-grade smoke 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 just like the original Nest Protect, it tells you what’s wrong and can even alert your phone.

Meet the all-new Nest Protect. 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.

“Heads-up, there’s smoke in the kitchen.”
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.

“Emergency, there’s smoke in the living room.”

It’s on your ceiling.
And on your phone.

App Silence

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

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

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

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

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.

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

The foam and particle board in much of today’s furniture make fires burn faster. Technology should keep up. The new Split‑Spectrum Sensor uses two wavelengths of light to detect smoke from both fast-burning and smoldering fires. Learn more about the Split‑Spectrum Sensor >
The Split‑Spectrum Sensor detects fast-burning fires quicker than any other photoelectric 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.

Steam is not smoke

Tests itself

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. How does Sound Check work? >
Lights your way

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’ favorite features so we made it better and brighter.
Steam is not smoke

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 2am. 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.

A Nest home.

Nest products are made to work together. And they can even work with lights, locks and other products in your home.

Heating systems can cause carbon monoxide leaks or spread smoke through your home in a fire. In an emergency, Nest Protect tells your Nest Thermostat to turn off the heat to keep the danger from spreading.
If your Nest Protect senses smoke or carbon monoxide, Nest Cam will automatically record and send you a video clip if it’s connected to Wi-Fi. And the entire video will be securely stored in the cloud so you can go back and see what happened.
There are a lot of products that work with Nest. Because gas heaters can be dangerous in a smoke or carbon monoxide emergency, if Nest Protect goes off, your Rheem water heater will turn off. See what else works with Nest >
