The smoke alarm that thinks, speaks and alerts your phone. Receive alerts throughout your home and directly to your smartphone.
It's time to expect more from your smoke alarm.
The new Nest Protect has an industrial-grade smoke sensor. It tests itself automatically and lasts up to a decade. It's also the first home alarm you can silence from your phone without any extra hardware required. And just like the original Nest Protect, it tells you what's wrong and can even alert your phone.
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.
And when one speaks, they all speak. So the alarm in your bedroom can tell you there's smoke downstairs.
New 10-year CO sensor.
Carbon monoxide is poisonous, but you can't see it or smell it. That's why Nest Protect has a new, long-lasting carbon monoxide sensor that keeps working for up to a decade.
Thoughtful, not annoying.
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.
Count sheep, not chirps.
No one should be woken up by a low-battery chirp at 2 am. 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 fine and there won't be any chirps. Sweet dreams.
