Product Description

Nest Protect Wi-Fi Smoke & Carbon Monoxide Alarm – S3003BWEF

For something as important as fire safety, you want a smoke alarm you can trust and rely on. That’s what you get with the battery-operated Nest Protect Smoke and Carbon Monoxide Alarm. This advanced smart device can distinguish between levels of urgency in smoke and CO levels, and sends you alerts on your smartphone immediately upon detection so you can take action right away.

Nest Protect Smoke and Carbon Monoxide Alarm

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 Smoke and Carbon Monoxide Alarm 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.

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.

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

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.

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

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 new Split‑Spectrum Sensor uses two wavelengths of light to detect smoke from both fast-burning and smoldering fires

New 10-year CO sensor.

Carbon monoxide is poisonous but you can’t see it or smell it. That’s why Nest Protect Smoke and Carbon Monoxide Alarm 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.

Thoughtful, not annoying.

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, 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: 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

Proven safe.

You have to know your smoke and CO alarms are safe. And we’ve proven Nest Protect is.

Meets all these standards:



Designed to connect.

If the Nest Protect in your kitchen senses danger, every Nest Protect Smoke and Carbon Monoxide Alarm in your home will speak up to make sure you know where the danger is – even if Wi-Fi goes down. And once you’ve checked that everything’s OK, you can hush them from your phone over Bluetooth LE.

When you go to bed tonight, look at your old smoke alarm.
You’ll probably notice a tiny little light. It could be green. Or red.
But what does it even mean?

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

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.

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

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

Nest Protect helps you before, during, and after something goes wrong.

Not just an alarm. A guide.

What To Do in the Nest app teaches your family how to get out of the house safely. It will also pop up on your phone if the alarm goes off. You can even enter an emergency contact so it’s right there when you need it.

Know what happened.

You’re not always home when there’s an emergency. So Nest Protect remembers what happened and shows you the details in a 10-day Safety History.

It helps you every month.

Nest will email you a monthly Home Report. You’ll see a summary of anything that happened and tips to help you stay safe.
