Meet Nest Protect, the completely redesigned smoke and carbon monoxide alarm from the makers of Nest. Nest Protect has a friendly human voice that informs you of a problem without making unnecessarily harsh sounds that split your eardrums, disturb your pets or make your children cry.

When five minutes is all it takes for a fire to take over a room, it’s critical that your smoke detector calmly alert you to the problem — no matter where you are. Nest Protect alerts you to issues from every alarm in the house, and on your phone. And it has the most accurate type of carbon monoxide sensor available on the market today, so you can detect invisible and odorless carbon monoxide gas that can be hazardous to your health.

Now you can control the critical technology you rely on to keep your home and family safe right from your Control4 system, without any extra hardware. Keep reading for more reasons to consider a Nest Protect smoke and carbon monoxide alarm for your home.

Tests Itself

Did you know that you’re supposed to test your smoke alarm once a month? Nest Protect checks its batteries and sensors around the clock, 400 times a day to be exact. It’s also the first alarm to quietly test its speaker and horn with Sound Check once a month.

Lights Your Way

The new Nest Protect has a motion detector that lights up as you walk underneath it. Pathlight emits the right amount of light to brighten your way without causing unpleasant eyestrain.

Knows Steam from Smoke

Nest Protect is the only alarm with Steam Check. It uses custom algorithms and a humidity sensor to look for steam, so you don’t get false smoke alerts.

Won’t Chirp

With Nightly Promise, Nest Protect has a quick green glow indicating that all your devices have tested themselves, the batteries are good and there won’t be any low-battery chirps.

Turns Off Heat

In an emergency, it tells your Nest Thermostat to turn off the heat to keep carbon monoxide leaks or smoke from spreading through your home in the event of a fire.

Records Automatically

Nest Protect automatically tells your Nest Cam to turn on if it senses smoke or carbon monoxide, so you can go back and review a video clip to see what happened.
