Nest Protect smoke & CO Alarm

The smoke alarm that thinks, speaks and alerts your phone.
 
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.
 
The smoke alarm that other alarms look up to.
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.
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.
 
In the 1970s, it would take about 30 minutes for a fire to take over a room. Today, it can take less than 5.
10-year Smoke/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.
 
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. Only sweet dreams.
