Descriptif

The PERIFENCE CLASSIC system, designed and developed by the OREP engineering office is a sensor fence made of welded rigid mesh panels with horizontal tubes. These are instrumented using a sensor cable cut (ref. OREP wire E).

This detection perimeter device is fully integrated into the fence and totally invisible. The detection wire is wired so as to form a current loop which analyzed by electronics ZUC40 constitutes an alarm area.

The upper part is fitted with detection breakable bent arms that detect the climbing. The panels are locked at the posts and integrate a sensor wire invisibly. PERIFENCE used the EPI-SURE connectors system to effect continuity of the sensor loop. The connection EPI- SURE guarantees the isolation of the electrical loop and allows rapid implementation and easy maintenance.

PERIFENCE Models

OREP offers a complete range of PERIFENCE detection fencing systems that allows to respond appropriately to the security specification of the sensitive site to protect.

• PERIFENCE CLASSIC Detection on horizontal tubes panel
• PERIFENCE+ 358 Dense mesh with horizontal detection
• PERIFENCE DOUBLE Horizontal AND Vertical Detection

ZUC40 Electronic

The principle of the detection is based on the analysis of the electrical characteristics of an isolated current loop which is formed by the closing sensor PERIFENCE.

• Analysis of the current loop impedance
• Analysis of the short-circuit
• Analysis of the variation of leakage current

The ZUC40 electronic board is could be mount in a standalone unit (2 or 4 zones), it can also be rack mounted (up to 10 zones per rack).

Configuration

The PERIFENCE can be installed in two types of configuration:

• An architecture with field electronic cabinet, consisting on ventilated thermostatically boxes witch control 2 or 4 zones,
• A centralized architecture with a detection bay equipped by ZUC40 electronic board racks and PERIVISION software in option.
