Nest Protect smoke and CO alarm

Nest Protect smoke and CO alarm.
 
The smoke alarm that other alarms look up to.
Thinks before it speaks.
Nest Protect has a friendly human voice that gives you an early warning. That way you can handle burning toast before it becomes a burning toaster.
Tells you where the danger is.
 
It’s on your ceiling. And on your phone.
 
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.
