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.

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.

When you add more products to your home, they can automatically work together.
And you can control them all from one place: the Nest app.

  • Heating systems can cause CO 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 CO, Nest Cam will automatically record a clip so you can go back and see what happened.

  • There are a lot of products that work with Nest. Connect your Philips hue lights to Nest Protect and they can flash on and off to help get your attention when the alarm goes off.
