Perifence™ double

Detector Fence with vertical and horizontal detections

The instrumentation of PERIFENCE® DOUBLE is performed by creating a sensor mesh in a heavy steel welded mesh panel that reinforces the detection capabilities of the system and the robustness of the fence.
Detection when there is a cut off, a shear, on peel and on climbing.
Reliability: Very low rate of false alarm
Performance: High level of detection
Modularity of alarms zones/invisible and discrete system,
perfect for the protection of industrial sites with high risks



The PERIFENCE® DOUBLE system, designed and developed by OREP Engineering office, is a detector fence that consist of panel with rigid welded mesh. The horizontal and vertical tubes are instrumented with sensor cables that detect when there is a cut off.


This perimeter detection device is fully integrated in the fence and totally invisible. The detection wire is placed in a way to form a current loop in which, analyzed by an electronic ZUC40, will constitute an alarm. PERIFENCE® DOUBLE uses EPI-SURE Connectivity to perform loop continuity. The top part of the PERIFENCE® is equipped with detector sills that allow detecting upper crossing.


EPI-SURE connection guarantees the insulation of the electrical loop and allows easy maintenance.
