Chapter 2: Installation
Installing the sensor cable
Caution:
FlexZone sensor cable must be conditioned before it is attached to the
fence.
Caution:
When installing FlexZone sensor cable during periods of freezing
weather (below 0º C, 32º F) additional care must be taken as the sensor cable is
less flexible, and the polypropylene cable ties may be prone to failure.
Cable handling rules
The FlexZone sensor cable converts minute vibrations in the fence fabric into
electrical signals. Any damage to the cable from mishandling or poor installation
practices will have a negative effect on the system's performance.
•
DO NOT bend, twist, jerk, knot, or kink the sensor cable.
•
DO NOT nick or scrape the sensor cable's outer jacket.
•
Avoid tight turns in the sensor cable, the minimum bend radius for FlexZone
sensor cable is 10 cm.
•
DO NOT place objects on the sensor cable or allow anyone to stand or walk
on the cable.
•
DO NOT allow the cable to fall off the side of the cable reel.
•
DO NOT apply excessive tension to the sensor cable at any time.
•
When using cable ties to attach the sensor cable to a fence, install the ties by
hand and pull them hand-tight until snug.
•
DO NOT use mechanical tighteners to attach cable ties to a fence.
•
DO NOT allow the sensor cable to be pinched between the fence and a fence
post, or any other object.
•
Keep the ends of the sensor cable clean and dry. If water enters the loose
tube it can cause corrosion and potentially freeze in the winter, which will
have a negative effect on sensitivity.
Note:
The number of cable passes required on a fence depends on the height of
the fence, the type of fence, and the required level of security (see "Fence height
recommendations" on page 9).
FlexZone sensor cable conditioning
Before installing FlexZone sensor cable, the cable must be conditioned. Prior to
conditioning, there may be excess center conductor in the cable, or the center
conductor may be adhered to the cable side walls after the manufacturing
process. Conditioning frees the center conductor and maximizes its movement,
