Sensor Concertina (cut off detection)

PERISTOP® detection technology is associated to concertina dissuasion.
It is easy to install and it is perfectly adapted to all type of site protection.
Adapted to all type of support, wall and fence.
Cut off and attempt crossing detection
Reliability: Very low rate of false alarms
Diameter and blade adaptable
Deterrent and great durability



PERICOIL is a concertina that detects when there is a cut off. It combines the concertina deterrent aspect and the detection technology of the PERISTOP®. Concertina networks are constituted with PERISTOP® wire detection in stainless steel. The detection wire is placed in a way to form a current loop in which, analyzed by an electronic ZUC40, will constitute an alarm. Cut off of a wire will constitute an alarm.

This perimeter detection device is fully integrated in the fence and totally invisible.

PERICOIL is dreadful when it is associated to detections bent arms that allow detecting climbing tentative.
