G-FENCE 600z is a fence-mounted intrusion detection system for perimeters up to 2000' (600m). G-FENCE 600z is made up of accelerometer detection sensing devices and passive cables (that carry communication and power) connected to a control unit, which together detect vibrations caused by climbing on, cutting, or lifting of the fence. When an intrusion occurs, the accelerometer transmits information to the control unit for analysis, after which an alarm is generated if the activation threshold is reached. Supplied with 12VDC, the self-contained control unit can be installed inside or outside the building. It can manage 2000' (600m) of cable distributed in 2 directions of up to 1000 ft. (300 m) each. Each 300' (100m) of cable section is equipped with 40 sensors, i.e., 1 sensor per panel and up to 120 sensors per cable direction. Upon an intrusion, alarm information is transmitted from the control unit by dry contacts.
