Electrified Sensor Concertina (cut off detection and electrified)

The association of PERICOIL technology and high voltage electrification makes a complete solution product. It becomes a successful product in the defense field due to it deterrent and repulsive aspect.
Adapted to all type of support, wall and fence.
Cut off and attempt crossing detection
High voltage electrical repulsion
Reliability: Very low rate of false alarms
Deterrent and great durability



PERICOILACTIV is an electrified concertina that detects when there is a cut off.
PERICOILACTIV combines the concertina deterrent aspect and the detection technology of the PERISTOP® and high voltage electrical repulsion. Concertina rolls are constituted with a PERISTOP® wire detection in stainless steel and an inside coil wire electrified maintained by insulators every 120 °. The energizer has a high voltage mode and a low-voltage mode.


Three types of detection are possible:

  • Detection when there is a contact with an electrified wires
  • Cut off power line or sensor razor wire
  • Line failure, grounding or insulation


PERICOILACTIV is dreadful when it is associated to detections bent arms that allow detecting climbing tentative. High security applications are associated to PERICOILACTIV rolls in order to create a stronger detection fence
