Why We Love It
- The smoke alarm that others look up to. Nest Protect is a smoke and carbon monoxide alarm with a split-spectrum smoke sensor to detect both fast -and slow-burning fires. It can send an alert to your phone, speak to you and even light the way in the dark
- It tells you what the danger is and where it is. The Split-Spectrum Sensor looks for both fast-and slow-burning fires. It also has a 10 year CO sensor so that it can tell you where poisonous, invisible CO is hiding
- You'll know, from anywhere. Nest Protect can alert your phone when something is wrong at home. You'll receive a message if the alarm goes off, if the batteries start to run low or if a sensor isn't working. And you can silence your Nest Protect using the Nest app
- Thoughtful, not annoying. Nest Protect checks itself over 400 times a day and lets you know if something is wrong. It also has Steam Check, so a nice, relaxing shower shouldn't cause your alarm to shout at you. And Pathlight, so it can light your way at night
- Easy to install. Nest Protect only takes minutes to set up with your iOS or Android device. Once you've added each of your Nest Protects to your Nest account, they will automatically connect to each other. Nest Protect is also simple to attach to the ceiling, thanks to a neatly designed back plate
