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 toast?

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 silence 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 2 am. 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 fine 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. In an emergency, Nest Protect tells your Nest Thermostat to turn off the heating to keep the danger from spreading.

  • If your Nest Protect senses a smoke or carbon monoxide emergency, 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. If your Nest Protect detects smoke or CO, it can tell your Bosch oven with Home Connect to turn off to prevent it from being damaged. See what else works with Nest >
