SPEC SHEET The new Nest Protect

Smoke and carbon monoxide alarm.

It thinks, speaks, and alerts your phone.

Meet Nest Protect.

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 also speaks up when there’s a problem, can be hushed from your phone, and it will even message your phone in case you’re not home.

How does it work?

Get alerts on your phone.

Nest Protect sends you a message when there’s a problem or the batteries run low.

Tells you what and where.

Nest Protect speaks up if there’s smoke or CO and tells you where it is, so you know what to do.

Sees the CO you can’t.

Carbon monoxide is an invisible,
poisonous gas. Nest Protect tells you where it’s hiding.

A light in the dark.

Usually Nest Protect has its light turned off, but when you walk underneath it, Pathlight can light your way.

Every second counts.

The Split-Spectrum Sensor looks for both
fast and slow burning fires.

Hush from the Nest app.

Just burned the popcorn? Quiet the false
alarm with your phone, not your dish towel.

10-year life span.

Nest Protect’s long-lasting sensors keep
you safe and sound for up to a decade.

Sleep safe and sound.

Nightly Promise is a quick green glow
when you turn out the lights that says everything’s working well.
