The Vision ZD2102 Door/Window Sensor is a Z-Wave sensor that detects whether a door or window is open or closed.
The sensor uses two magnetic units to detect movement; one is placed on the moving part of the door or window and the other unit on the frame. When the detector is triggered it sends an alert signal to up to four associated Z-Wave devices.
The sensor can have an external switch connected to it and includes an internal tamper switch.
It is easily fitted to any door or window using screws or double-sided tape. Battery replacement is simple and the detector even tells you when they need replacing by flashing its LED and sending an alert to the central controller.
Note: To be used as part of a Z-Wave network this sensor requires a suitable Z-Wave controller.
