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, 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 it tells you what’s wrong and can even alert your phone.
10-year CO sensor.
Carbon monoxide is poisonous, but you can’t see it or smell it. That’s why Nest Protect has a long-lasting carbon monoxide sensor that keeps working for up to a decade.
Tests itself
You’re supposed to test smoke alarms monthly. But most 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 siren once a month.
Lights your way
If 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' favourite features, so we've made it better and brighter.
Steam is not smoke
Has your alarm ever yelled at you for having a shower? Nest Protect comes with Steam Check. It uses custom algorithms and a humidity sensor to look for steam so that 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.
Look for the light ring.
In addition to its voice, Nest Protect uses colours to communicate. And we’ve given the new Nest Protect a brighter light ring so it’s easier to see in an emergency and better at helping you see things in the dark.
Nightly Promise
Nest Protect constantly monitors its sensors and batteries. A quick green glow when you turn off the lights says that everything's working.
Pathlight
When you walk under Nest Protect at night, it will light your way. You can choose different light levels or turn Pathlight off entirely in the app.
Heads-Up
If there's only a little smoke, like you've just burned toast, it will glow yellow and give you a friendly Heads-Up so you can check on things.
Emergency
When smoke or carbon monoxide reaches dangerous levels, Nest Protect sounds the alarm, pulses red and tells you where the emergency is.
