3. APPLICATION
To ensure the required detectability (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 and of tribocable laying and fastening schemes;
•
fence uniformity, i.e. the fence should be made of the same material as different ‐ material
sections generate signals of different strength when subjected to an unauthorized action;
•
tribocable proper installation and tightness;
•
SPU sensitivity setting with specified detectability.
3.1. Versions of Fence Equipping
Possible are the following versions of the guard alarm installation:
‐ flexible fence made of reinforced barbed tape , wire netting, wire netting “Rabitsa”, barbed
wire, 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).
3.1.1.
Flexible Fence (Fig
. 1)
Flexible fence is actually a fence made of metal wire netting according, barbed wire, wire of
rust ‐ resistant steel, bimetallic wire, reinforced barbed tape, etc.
The sensor is mounted directly on the fence flexible elements. The supports enabling a
violator to get over the fence without touching its flexible elements being available, the sensor is
mounted on the supports as well.
The “Alarm” signal is generated on the flexible fence under local deformation of the fence and
the sensor fastened to it in case of unauthorized penetration by getting over the fence, no facilities
being used, and as a result of damage to the fence, the sensor, and its fasteners.
To obtain the required noise immunity, be sure to limit the flexible fence mobility under wind
as much as possible.
3.1.2. Wire ­ Netting Fence (Fig. 1 а )
The wire ‐ netting fence should meet the following requirements: make sure the netting is
stretched uniformly between the fence supports in a horizontal plane with a force of 100 kg,
minimum.
3.1.3. “Rabitsa”
Wire‐Netting Fence (Figs 1b and
1c)
The “Rabitsa” wire ‐ netting fence should meet the following requirements:
•
make sure the netting is stretched uniformly between the fence supports in a horizontal plane
and fastened to the upper and lower wire ropes (Fig. 1b);
•
a frame made of angle sections being used, make sure the netting is stretched uniformly and
fastened to the all sides of the frame. In addition be sure to lay the sensor along the upper
angle section of the frame and the fence supports (Fig. 1c).
