Nest Protect smoke and CO alarm

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 popcorn?
It’s time to expect more
from your smoke alarm.
Nest Protect has been redesigned from the inside out. It has a Split-Spectrum Sensor and tests itself automatically. 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 can even alert your phone.
Sees both fast and slow burning fires.
The foam and particle board in much of today’s furniture make fires burn faster. Technology should keep up. The Split‑Spectrum Sensor uses two wavelengths of light to detect smoke from both fast-burning and smoldering fires.
In the 1970s, it would take about 30 minutes for a fire to take over a room. Today, it can take less than 5.

Thoughtful, not annoying
Tests itselfYou’re supposed to test smoke alarms monthly. But 9 out of 10 people don’t. So Nest Protect checks its batteries and sensors over 400 times a day. And it’s the first alarm that uses Sound Check to quietly test its speaker and horn once a month.
Lights your wayIf you need a glass of milk in the middle of the night, Nest Protect lights up as you walk underneath it. Pathlight is one of our customers’ favorite features so we made it better and brighter.
Steam is not smokeHas your alarm ever yelled at you for taking a shower? Nest Protect is the only alarm with Steam Check. It uses custom algorithms and a humidity sensor to look for steam, so you can enjoy a nice, quiet shower.
Count sheep, not chirps.
No one should be woken up by a low-battery chirp at 2 a.m. 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.
