Rigid fence types
Rigid fence types do not conduct vibrations as well as flexible fence types due to
their materials and construction. FlexZone provides an increased sensitivity
setting for use with rigid fences. It is recommended to install the FlexZone sensor
on a limited length section of the rigid fence to test and verify that the detection
sensitivity meets the security requirements before installing a full length
perimeter.
Palisade fences
Figure 2: Rigid fence (palisade)
A typical palisade fence panel consists of metal pales fastened onto horizontal
rails. These fence sections are secured to fence posts which are securely
anchored to, or into, the ground.
Gates
There are generally two types of gates used with fences, swinging gates and
sliding gates. The type of gate protection required is determined by:
• the type of gate
• the frequency of gate use
• when the sensor is active
• the type of ground beneath the gate
• the overall protection plan (the number of processors and sensor cables, and
their location relative to the gate in question)
Gates should consist of fence fabric on a rigid frame that includes horizontal and
vertical bracing.
• Firmly attach all gate hardware accessories (minimum free-play).
• Make sure that double gates have travel stops (rigid anchors).
