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, thereby providing the greatest sensitivity. Cable conditioning is best
done by two people and typically takes about 10 minutes for a 150 m sensor cable. FlexZone
cable conditioning can be done by a single person, but it can take significantly longer to complete
due to repeatedly walking back and forth.

conditioning
procedure
(part 1 - cable preparation)
1. Dispense the sensor cable alongside the fence in a long straight line.
2. Carefully remove 30 cm (12 in.) of the black outer jacket, shield and clear tube to expose
30 cm of the center conductor at both ends of the cable. For armored cable, remove 45 cm
(18 in.) of the armor from each end of the cable, then expose 30 cm (12 in.) of center
conductor at each end.
Note
This procedure applies to both standard FlexZone sensor cable and
armored FlexZone sensor cable.
Note
If site conditions prevent the cable from being laid out in a straight line,
minimize the number of turns and use as large a turn radius as
possible. Turns in the cable will require an increase in the amount of
pulling force needed to move the center conductor back and forth.
Note
If the cable is moved to a more open area to be conditioned, move it
carefully back to the installation location following the process. Avoid
using excessive pulling force and do not pull the cable around corners
or fence posts when it is repositioned.
