Get alerts on your phone - Nest Protect can send you a message when there is a problem or the batteries run low.

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

Sees the CO you cant - Carbon monoxide is an invisible, poisonous gas. Nest Protect tells you where it's hiding.

A light in the dark - Usually Nest Protect has it's 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 low burning fires.

Hush from the Nest app.- Just burned the popcorn? App Silence lets you quiet the alarm from your phone.

10-year life span - Nest Protects long lasting sensors help 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 is working well.

There has never been a smoke and CO alarm quite like this. Nest Protect looks for fast-burning fires, smouldering fires, and carbon monoxide. It also speaks up when there is a problem, can be hushed from your phone, and it will even message your phone in case you're not home.
