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.
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.
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 smoldering fires.
10-year CO sensor.
Carbon monoxide is poisonous but you can't see it or smell it. That's why Nest Protect has the most accurate type of carbon monoxide sensor available. We also improved our carbon monoxide sensing algorithm. And we'll keep working to make it better and better because people depend on it.
Thoughtful, not annoying.
Tests itself: You're supposed to test smoke alarms monthly. But 9 out of 10 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 horn once a month.
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.
