Interlogix Wireless Shock Sensor

The Interlogix Wireless Shock Sensor has the following three main functions:  To detect the vibrations made by an intruder trying to break a window or door. To detect a window or door opening.  To detect tamper situations, such as an intruder removing the sensor cover. Vibrations cause a momentary open circuit in the shock element of the sensor. The circuit closes again when the vibration stops. The sensor micro-controller “sees” the open/close action as a pulse, causing the sensor to transmit an alarm signal. The sensor has two different detection modes:  Gross Attack – detect a violent blow sufficient in length to trip the sensor.  Pulse Count – detect a sufficient number of less violent blows (rapping or tapping). The sensor also includes an internal magnetic reed switch that must be disabled if it is not used. A cover tamper provides additional security if an intruder tries to disable or damage the sensor
