Nest Protect, Smoke Alarm + Carbon Monoxide Detector, Wired

Product information

Nest Protect will keep you safe without getting on your nerves. This smart smoke and carbon monoxide (CO) alarm is designed to keep you informed without immediately howling at you while you're making your dinner, so you can stay safe without getting annoyed.

Alarm updates wherever you are
Protect will also send a message to the app on your smartphone using your home Wi-Fi connection if the alarm goes off or the emergency batteries run low. It will also keep you informed of battery and sensor status before you go to bed, so you no longer have to put up with the alarm chirping throughout the night and keeping you up.

Safe for kids.
Children can sleep through alarms. So in addition to alarm sounds, Nest Protect uses Voice Alarms to wake kids up and help them avoid danger.

Easy installation
Nest Protect only takes minutes to install. Connecting to Wi-Fi and setting them 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.

About Nest Wave
Due to safety concerns, Nest Wave (a feature that enables you to turn off your alarm with a wave of the hand) has been disabled in this unit. Once a solution that ensures Nest Wave works as intended has been reached, Nest will update their software to turn this feature back on. This will only happen after extensive testing and once we have received approval from safety agencies in the US, Canada and UK.
