Testing device for an intrusion detection system

摘要

A taut wire intrusion detection system for a fence includes a testing device adapted to be actuated from a central station to apply a mechanical force to the fence wire in order to cause it to simulate an intrusion. The system further includes a testing circuit at the central station for actuating the testing device, and an indicator at the central station which receives the signal from the detector, and thereby indicates the actual response of the detector to the mechanical force.
