Safety shouldn’t be annoying.

We all know why smoke alarms are torn off the ceiling or missing batteries: because every time you make stir-fry, the smoke alarm cries wolf. Or just as you’re falling asleep, you hear a low-battery chirp. They’ve become annoying. And that’s a safety issue.

In over half the home fires in Great Britain, there was no smoke alarm or the smoke alarm failed according to the Department of Communities and Local Government.

So we made something new. Meet the Nest Protect smoke and carbon monoxide (CO) alarm.

We made a smoke and CO alarm you’ll love, because hating it is dangerous.

Burned the toast? Nest Protect won’t just start yelling at you.

Before turning on a loud, howling alarm, Nest Protect gives you an early warning we call Heads-Up. Nest Protect lights up yellow and speaks with a human voice. It tells you where smoke is or when carbon monoxide levels are rising. This gives you an earlier warning if there’s an emergency, or allows you to silence Nest Protect if it’s just a nuisance alarm, like an overly enthusiastic toaster.

Silence alarms with a wave.

No more frantically swinging towels at the smoke alarm to quiet it down. If there’s a nuisance alarm, just stand under Nest Protect and wave your arm to silence the alert. As you wave, your hand should be 60 cm to 240 cm away from the alarm.

Emergency. There’s smoke in the bedroom.”

A clear voice when things go wrong.

In addition to an alarm sound, Nest Protect speaks to you with a human voice. It tells you what the problem is and where it is. And if you have more than one Nest Protect, they connect so they can speak up at the same time even if Wi-Fi is down.

Voice alarms can be important to your family’s safety. You have more information when seconds count. And according to a study, children can sleep through a beeping alarm. So Nest Protect sounds the alarm and uses a human voice to help kids wake up.

Sees what’s invisible. Sees what’s invisible.

You can’t see carbon monoxide. Or smell it. It’s a silent killer that causes early symptoms that are easily mistaken for the flu. That’s why the United Kingdom has passed laws that make carbon monoxide alarms as common—and necessary—as smoke alarms.

So Nest Protect constantly looks for dangerous levels of carbon monoxide. You can’t see it, but Nest Protect can.

Works with your Nest Thermostat.

If Nest Protect’s carbon monoxide alarm goes off, your Nest Thermostat automatically turns off your boiler—a possible source of poisonous carbon monoxide leaks. In addition, the Nest Protect activity sensors improve the Auto-Away feature of your Nest Learning Thermostat.

Automatic CO shutoff requires an active WiFi Internet connection at the time of the event and relies on having both Nest Protect and Nest Learning Thermostat added to the same home in a Nest Account. This feature is not part of British Standards Institution testing and listing. See How the Nest Thermostat and Nest Protect work together in a carbon monoxide emergency >

You don’t have to be afraid of the dark.

Next time you stumble out of bed in the middle of the night, Nest Protect will automatically light your way. You can turn the Pathlight feature on or off using the Nest app.

Makes you a promise.

Low-battery chirps ever rattle your dreams? Nest Protect has a better way: Nightly Promise. It’s a quick green glow when the lights go out that means the batteries and sensors are working. It also means no dreaded chirps at midnight.

If there’s an issue, like the batteries need replacing, the light ring will glow yellow. Just wave at Nest Protect and it will tell you what’s wrong.

Sweet dreams.
