Google Nest Protect V2 AC Power Duo Pack

With the Google Next Protect V2 AC Power, 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 Google 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 70dB. 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 Google Nest Protect V2 to other Google Nest products, like the Google Nest thermostat and the Google 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 Google Nest Protect V2 Duo Pack (AC Power) runs on 230V and 3 AA batteries that are included by default.

Smoke detectors have a maximum lifespan of 10 years, the sensor won't work anymore after that. This says nothing about the quality of the detector.

Note: the back of the Google 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.
