Google Nest Protect Wired Smoke and Carbon Monoxide Alarm (2nd Generation) (S3003LWES) - White

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 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. 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. 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. 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’ favorite features so we made it better and brighter. Steam is not smoke Has your alarm ever yelled at you for taking a shower? Nest Protect is the only alarm with Steam Check. It uses custom algorithms and a humidity sensor to look for steam, so you can enjoy a nice, quiet shower. 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. Look for the light ring. In addition to its voice, Nest Protect uses colors to communicate. And we gave 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.
