Protect your loved ones and your home

Detects levels of smoke and carbon monoxide within your home and tests itself automatically.

Receive clear direction in an emergency

Alarm speaks to you with a human voice and tells you the location and levels of smoke or carbon monoxide when they are present.

Send alerts to your smartphone

Provides battery and sensor status notifications so you're always informed, and safety history so you can see what happened over the last 10 days. You can even silence the alarm from your smartphone.

Hardwired connection provides dependable power

Wired directly to your electrical system, with backup battery to ensure operation during a power outage.

Get an early warning signal

If a cooking mishap leads to a small amount of smoke, Nest Protect will let you know without setting off the full alarm.

Stay on top of any situation

Synchronized sensors ensure that when 1 alarm senses danger, every alarm in the house will make you aware of the situation.

If carbon monoxide is present, Nest Protect links with your Nest Thermostat (sold separately) to automatically turn off your gas furnace.

Light your path at night

Pathlight illuminates your way in the dark. Adjust its brightness, leave it on as a nightlight or turn it off from the Nest Protect app.

 

Thinks, speaks, and alerts your phone.

There’s never been a smoke and CO alarm quite like this. Nest Protect looks for fast-burning fires, smoldering fires, and carbon monoxide. It speaks up when there’s a problem and can send a message to your phone if you’re not at home.[1] And it helps keep you safe and sound for up to a decade.
