How Does it Work?
Get alerts on your smartphone
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
Pathlight turns on like a night light when you walk near the Nest Protect, and turns off when you walk away.
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 sensors are built to last for up to a decade.
Sleep safe and sound
Nightly Promise emits a quick green glow when you turn out the lights, signaling that the batteries and sensors are working.
Not sure which Nest Protect to get? Just check the smoke alarm you have now. If it connects to wires, you'll want Nest Protect (Wired). If it doesn't, you should get Nest Protect (Battery).
