Monitor the status of any open/close object including a door window cabinet drawer etc. with the 2GIG Wireless Thin Door/Window Contact. The wireless battery-powered sensor works with the 2GIG Go!Control panel or Vario wireless receiver and features an exceptionally narrow width (3/4 ) to fit into small spaces. When the monitored door/window is opened the sensor signals the control panel to trigger an alarm. In addition to monitoring the primary door/window the Thin Door/Window Contact can be used for a second security zone. It has an external input that accepts Normally Closed (NC) dry contact devices . The sensor also has a tamper-resistant cover that will trigger an alert if removed. How It Works: The Door/Window Contact consists of two pieces (sensor and magnet) which easily install using the included mounting tape. The sensor mounts on the door/window itself and the magnet mounts on the frame. When the two are separated the sensor signals the control panel.
