Cable installation on different fence types

7. Return to the first support post and install cable ties every 25 to 30 cm
(10 to 12 in.) along the second fence panel (points 11 to 16).
8. Repeat this procedure, one fence panel at a time, until the cable is fully
installed in the zone.
9. Verify that the tension on the cable is consistent along the entire length.
Loose sections of sensor cable can result in low detection sensitivity.
Cable installation on different fence types
The following section describes the installation requirements for specific fence
types. Exceptions to these may occur if an unusual type of fence construction is
encountered. Contact your Senstar representative.
On chain link fence
The following cable layouts are recommended, depending on fence height:
•
for fences up to 2.5 meters (8 ft.) tall - a single pass of sensor cable
•
for fences greater than 2.5 m and less than 4.5 m, and on vinyl coated fence -
a double pass of sensor cable. The cable is installed at approximately 1/3 and
2/3 the height of the fence.
•
for fences exceeding 4.5 m (15 ft.) in height - three or more passes of sensor
cable This depends on fence fabric and structure, and on the level of security
required by the system. These cable passes should be equally spaced.
If the chain link fence has been constructed with its lower edge placed in a
concrete footing, detection will be poorer near the bottom than for a fence with a
free lower edge. In such cases the processor gain and the signal threshold may
require further adjustments.
