Alerts You When Your Door/Window Has Been Opened

Know when your door or window has been opened or closed with the Ecolink Wireless Door/Window Crystal-Based Sensor, 319.5 MHz. This device is compatible with Qolsys, Interlogix, and GE panels/receivers (319.5 MHz wireless frequency) and consists of a sensor body and a magnet piece. The magnet piece mounts on the actual door/window while the sensor body mounts on the door/window frame. Whenever the sensor and magnet are separated or joined together (upon opening or closing the door or window), an alert is triggered. Plus, it includes an external hardwired contact, which is ideal in areas where the sensor cannot be mounted near the magnet.
