Designed for integration into any standard Z-Wave network, the Ecolink Z-Wave Door/Window Sensor monitors a door, window, or any other open/close object. The unit consists of two components: the sensor and the magnet. The sensor mounts on the door/window frame, and the magnet mounts on the door/window itself. When the two parts separate, an alert is triggered. Both parts easily install with the included mounting hardware or double-sided tape. Two interchangeable cases (brown, white) are included so you can match the sensor to your home’s decor. FEATURES: Detects up to 5/8-inch gap. Uses rare earth magnet. Tamper alert when cover opens. Wireless range up to 100 feet. Mounting hardware included.
