3. Continue this back and forth flossing motion until the center conductor moves
easily with very little resistance.
4. When the conditioning procedure is complete, release the tension on the
center conductor, and cut off any center conductor that was damaged during
conditioning.
Note: When conditioning is complete, the center conductor usually extends an
additional 15 to 30 cm out of the cable jacket at both ends, and it slides easily in
both directions.
Installing cable on chain-link fences
• Attach the sensor cable to the secure side of the fence (the side opposite the
threat).
• Secure the cable to the fence so that it maintains a constant height above
ground (i.e., if the fence steps up a hill, the cable should also step up the hill).
• Use UV resistant polypropylene cable ties spaced 25 to 30 cm apart to attach
the sensor cable to the fence.
• Pull the cable ties until they are hand tight and the cable is snug to the fence.
• Attach the cable ties to the center of a link (one wire) NOT at the junction of
two fence wires.
• Optionally, for increased security use two steel fasteners per fence panel in
addition to the polypropylene cable ties. Hand-tighten the steel fastener on a
fence wire adjacent to a polypropylene cable tie to hold the cable snuggly
against the fence without crushing or distorting the sensor cable in any way.
DO NOT use a mechanical tightening device.
• DO NOT attach the sensor cable to tension wires.
• Attach the sensor cable at least 30 cm away from horizontal support bars and
other cables.
• For a single cable pass, attach the sensor wire to the middle of the fence.
• Avoid vertical drops greater than 1 m when installing FlexZone sensor cable.
Vertical drops of 1 m or more can result in an area with excessive sensitivity,
which may cause nuisance alarms. Install vertical cable drops that are greater
than 1 m with a minimum 15º slope.
• Keep the ends of the cable clean and dry.
