How it Works

The device consists of two modules – the magnet and the detector. These both work harmoniously together to sense when you open your door or window, so it can send that information wirelessly through the high-end reed switches, transmitting the signal straight to your control hub.

The door contacts can be installed within minutes and operate straight out of the box with a battery that can last for up to 7 years without replacement.
