With the Next Protect V2 AC Power, (3 units) you'll be aware of any possible smoke development or carbon monoxide leaks in your home anywhere, anytime. As soon as the smoke and carbon monoxide detector is mounted to your ceiling, you can use the Nest app on your smartphone, tablet or smartwatch to manage it. Whenever the detector detects smoke or carbon monoxide, it signals you by means of a female voice of 70 decibels. This voice tells you exactly where in the house the danger has been found. The app also keeps you up to date with respect to low battery status or sensor outages. Use WiFi to connect the Nest Protect V2 to other Nest products, like the Nest thermostat and the Nest IP camera. This way, you get more benefits from the separate products. A green light will switch on as soon as the motion sensor detects movement in the dark. The Nest Protect V2 Duo Pack (AC Power) runs on 230V and 3 AA batteries that are included by default.
The Nest Protect V2 only works with your existing mains electricity.
Note: The back of the Nest on AC power protrudes about half a centimeter. This makes it impossible to install the detector flush with the ceiling, so you have to mount it to a point of contact.
