What is Perifence?

The system comprises of a rectangular weld mesh fence whose horizontal tubes are lined with a detection wire creating an electrical loop.

This perimeter detection system is therefore entirely integrated into the fence and completely invisible. The detection wire consists of a screened mono-conductor and all the detection wires are installed and connected to create a currentloop, which constitutes the alarm zone.

The fence creates a vertical barrier which cannot be defeated.

The system is equipped with breakable bent arms, which enable the detection of attempts to breach the upper part of the fence. These arms are mounted on support posts of the fence and are breakable in two directions, from exterior to interior and interior to exterior.

A force applied by an attempt to climb over the structure will collapse these breakable arms and subsequently cut the PeriStop wire, causing an alarm.
The system is monitored by an electronic control unit.

Each zone is connected to the control unit which continuously monitors the state of the loops.
(Continuity monitoring, current drop and short circuits). Cutting a detector wire will cause an alarm.
