Nest Protect alerts your phone when something’s wrong when you are not home. In the unfortunate instance when something isn’t quite right, the Nest Protect speaks up to tell you if there is smoke or carbon monoxide, and where the danger is.It is also the first alarm you can silence from your phone. Simply download the Nest app to your Smartphone to gain full control of the situation.The smoke and carbon monoxide tests itself so you don’t have to. Taking over 400 checks a day, it will be sure to let you know if things aren't quite as they should be. Such a commitment will last for up to 10 years thanks to the long-life sensors.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. Because this smoke detector is wired, it comes with a 230V AC Connector so it can be hard wired into the mains. In the event of a power cut, the three back up batteries (supplied) can come in useful.
