Google Nest Protect Smoke + Carbon Monoxide Alarm (2nd Gen) Wireless - White

Nest Protect

The smoke alarm that thinks, speaks and alerts your phone.

It’s time to expect more from your smoke alarm.

Nest Protect has been redesigned from the inside out. It has a Split‑Spectrum Sensor, tests itself automatically and lasts up to a decade. It’s also the first home alarm you can hush from your phone without any extra hardware required. And it tells you what’s wrong and can even alert your phone.

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.

And when one speaks, they all speak. So the alarm in your bedroom can tell you there’s smoke downstairs.

App Silence

Silence alarms with your phone, not your tea towel. If everything’s under control and there’s only a little smoke, silence the alarm from the Nest app.

Phone alerts

Everyone in your family can know what’s going on, from anywhere. When something’s wrong, Nest Protect sends everyone an alert in case no one’s home.

No chirps

Tired of being woken up at 2 a.m. by your smoke alarm? Long before it has to chirp, Nest Protect tells you that its batteries are running low with a message on your phone.

Sees both fast and slow-burning fires.

The foam and particle board in much of today’s furniture make fires burn faster. Technology should keep up. The Split‑Spectrum Sensor uses two wavelengths of light to detect smoke from both fast-burning and smouldering fires.

Count sheep, not chirps.

No one should be woken up by a low-battery chirp at 2 a.m. 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 good, and there won’t be any chirps. Sweet dreams.

10-year CO sensor.

Carbon monoxide is poisonous, but you can’t see it or smell it. That’s why Nest Protect has a long-lasting carbon monoxide sensor that keeps working for up to a decade.

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.

Lights your way

If you need a glass of milk in the middle of the night, Nest Protect lights up as you walk underneath it. Pathlight is one of our customers' favourite features, so we've made it better and brighter.
