Meet Nest Protect™ smoke + carbon monoxide alarm

The smoke alarm other alarms look up to.

The Nest Protect 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, it tells you what’s wrong and where.

PRODUCT BENEFITS

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.

Every second counts

The new Split-Spectrum Sensor uses two wavelengths of light to detect smoke from both fast and slow-burning fires.

Hush from the Nest app

Just burned the popcorn? Silence the false alarm with your phone, not your dish towel.

Tells you what and where

Nest Protect speaks up if there’s smoke or carbon monoxide and tells you where it is, so you know what to do.

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.

No chirps

Tired of being woken up at 2 AM 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. A quick green glow when your turn out the lights says everything’s working.

A Nest Protect Story

Roger Mason loves new technology. His wife Isabelle does not. So when he brought home a Nest Protect: Smoke + Carbon Monoxide alarm, she was skeptical. And when he got an alert on his phone from Nest Protect that there was smoke in her home, she was dubious. There was nobody home but the dogs - what could be on fire. Just in case, she changed her plans and came back home to find a box of granola bars and Goldfish crackers on fire in the kitchen.

The culprit? Inveterate counter surfer and 80-pound-cuddle-bug, Cody.

INSTALLATION

Which Nest Protect should I get? Just check the smoke alarm you have now. If it connects to wires, you’ll want Nest Protect (Wired 120V). If it doesn’t, you should get Nest Protect (Battery).

Now you're ready to set up your Nest Protect in just minutes using your iPhone, iPad, or Android device. Here's a step-by-step guide on setting up your new Nest Protect.
