  • Google Nest Protect Wired Smoke and Carbon Monoxide Alarm (White, 2nd Generation)

    Every month, you’re supposed to test your smoke alarms. Next month, why don’t you fully upgrade your smoke alarm? The Google Nest Protect Wired Smoke and Carbon Monoxide Alarm (White, 2nd Generation) has been completely redesigned to be one of the best smoke and carbon monoxide detectors available. Equipped with a Split-Spectrum Sensor, it will test itself automatically, and can last up to 10 years. It’s one of the first home alarms you can silence from your phone without any additional hardware requirements, and it can even send alerts to your phone if something is wrong.

    The Google Nest Protect is able to talk in a friendly, human voice that gives you early warnings, letting you know where the danger is. This way you can manage a smoking toaster before it becomes a burning toaster. They’re also connected, this way when one speaks the rest speak as well. This means if there is smoke downstairs, you’ll hear the alarm in your upstairs bedroom. A major portion of today's furniture if made with foam and particle board, both materials are known for burning fast. To keep up with this fact, technology has continued to evolve and improve. The Google Nest Protect has a Split-Spectrum Sensor that uses two wavelengths of light that are designed to detect smoke from both fast-burning and smoldering fires.

    Carbon monoxide is poisonous gas that’s both odorless and invisible to the human eye. To protect you from this gas, the Google Nest Protect has the most accurate carbon monoxide sensor available, with an improved sensing algorithm. Plus, it’s being continuous worked on for more improvements as people continue to depend on these detectors. Since you’re supposed to test your smoke alarms on a monthly basis, the Nest will automatically test itself. It will check both its batteries and sensors over 400 times in a day. It’s also the first alarm to perform a Sound Check that quietly tests both the speaker and horn once every month.

    With all these different tests and checks, you may be worried about the alarm waking you up with a test or “low battery” alert at 3am. Thankfully, the Nest Protect has a Nightly Promise. When you turn the lights off and see a green glow, it means that all the Nest systems have testes themselves, the batteries have enough power, and it won’t make any sound to wake you up, unless there is a real emergency. offers the Google Nest Protect Wired Smoke and Carbon Monoxide Alarm (White, 2nd Generation), and other Google related products, at affordable prices.

    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.
