The Mini Door/Window contact detector consists of two parts; a Detector and a Magnet. They are designed to be fitted to doors or windows with the Magnet mounted on the opening part and the Detector mounted on the fixed frame. Opening the protected door/window will remove the magnetic field, trigger the Detector and generate an alarm condition, (if the system is armed). The Door/Window Detector is a Z-Wave enabled device and is fully compatible with any Z-Wave enabled network. If several windows need to be protected, adopt the wire according to the placement as mentioned below. This should be wired to the terminal block provided in the battery compartment in series connection.
