This system has been assessed over a section of Anti-Intruder Weld Mesh Fence. One loop of sensor cable was attached to the 2nd and 19th strand from the top of the fence fabric using black plastic cable ties every 200 mm with an additional two reinforced metal cable ties per bay. Another run of sensor cable in flexible armoured conduit was tied to the centre strand of the barbed wire topping using plastic cable ties every 200 mm. The installation drawings are held by CPNI.
The Anti-Intruder Weld Mesh Fence is built to BS 1722 Pt10 and is:
a rolled welded mesh;
apertures of 75 mm vertical x 25 mm horizontal and 3 mm strand thickness;
height of the fence fabric is 2.4 m;
topped with three strands of barbed wire;
overall height of 2.9 m to the top strand of barbed wire; and
each bay is 3 m in width and buried 300 mm into the ground.
