Nest Protect Gen2 Smoke + Carbon Monoxide (Battery Powered)

Know more, worry less

Nest Protect sends a message to your phone or tablet if it sounds the alarm for smoke or carbon monoxide. It will also send you a message if the batteries start to run low. In addition to an alarm sound, Nest Protect speaks to you with a human voice. It tells you what the problem is and where it is so you know what to do. And if you have more than one Nest Protect, they can speak up at the same time even if Wi-Fi is down.

When you turn off the lights to go to bed, you’ll see your Nest Protect glow green for a second. That means batteries and sensors are working. It also means you won’t be waking up at 2am to low-battery chirps.

Sees what’s invisible. You can’t see carbon monoxide. Or smell it. Its early symptoms are easily mistaken for the flu, but longer exposure can be deadly. That’s why Nest Protect constantly looks for dangerous levels of carbon monoxide.

Easy installation. Nest Protect (Battery) take only minutes to install. Connecting it to Wi-Fi and setting it up with your iPhone, iPad or Android device also takes just a few minutes. Every Nest Protect in your home will connect to the others automatically.
