3. Application
To ensure the required detector operation stability (unauthorized actions detection), high noise immunity
(actually an utter absence of false responses) and specified sabotage resistance
THE FOLLOWING SHOULD BE PROVIDED:
•proper fence mounting (flexible fences should be stretched uniformly with specified tension force);
•combination of different-type fences with respective schemes of sensitive element laying and fastening;
•fence uniformity, i.e. the fence in one detection zone should be made from the same material because
different-material sections generate signals of different strength when subjected to an unauthorized
action;
•sensitive element proper installation and tightness;
•SPU detection zones optimal sensitivity setting;
Versions of Fence Equipping
Possible are the following versions of the guard alarm installation:
-flexible fence made of reinforced barbed tape, element netting, element netting “Rabitsa”, barbed
element, etc. (Fig.1);
-rigid (continuous) fence made of metal elements (forged and welded gratings, solid metal plates,
corrugated plates, etc.), concrete, bricks, wood, etc. (Fig.2);
-gates, wickets, etc. (Fig.3).
3.1. Flexible Fence (Fig. 1)
Flexible fence is actually a fence made of metal element netting
according, barbed element, element of rust-resistant steel, bimetallic element,
reinforced barbed tape, etc.
The sensitive element is mounted directly on the fence’s flexible
elements. The supports enabling a violator to get over the fence without
touching its flexible elements being available, the sensitive element is
mounted on the supports as well.
The “Alarm” signal is generated on the flexible fence under local deformation of the fence and the sensitive
element fastened to it in the case of an unauthorized penetration by climbing over the fence, without any
facility, and as a result – deformation/vibration of the fence and the sensitive element over its fasteners.
