•
The smallest allowable bend radius for Armour-FLEX sensor cable is 15 cm (6 in.).
•
DO NOT subject Armour-FLEX cable to excessive tension (max. 3.4 kg, 7.5 lb).
•
Armour-FLEX cable comes in 100 m (328 ft.) lengths. You can splice up to three sections of
Armour-FLEX together to create a 300 m (985 ft.) zone (see
).
•
Use Armour-FLEX condulet fittings to protect cable splices and terminations (see
•
If you must move Armour-FLEX after dispensing the cable on the ground, carefully move it in
5 m (16 ft.) lengths, to prevent cable damage.
•
Use UV resistant polypropylene cable ties, stainless steel straps, or wire ties to secure the
Armour-FLEX to the fence fabric.
•
Secure Armour-FLEX tightly to the fence fabric at either the midpoint of the chain-link or at the
junction of two fence links.
•
Keep the ends of the Armour-FLEX cable dry.
Mark 2 Armour-FLEX cable
conditioning
procedure
Before installing Mark 2 Armour-FLEX 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 requires two people to complete and typically takes less than 10 minutes for a 150 m
sensor cable.
Cable
conditioning
procedure
(part 1 - loosening the center conductor)
1.
Dispense the sensor cable alongside the fence in a long straight line.
2.
At both ends of the sensor cable, carefully remove 45 cm (18 in.) of the armoured jacket, then
remove 30 cm (12 in.) of the black jacket, shield and clear tube to expose 30 cm of the center
conductor.
3.
Check the ends of the cable to verify that the center conductor is free to retract or extend
If an end is damaged enough to prevent the free movement of the center conductor, cut off the
damaged section and restrip the cable.
4.
At both ends of the cable, use a cable tie, or a 2.5 cm (1 in.) piece of the outer jacket, to secure
the center conductor to prevent it from retracting into the cable during the conditioning
procedure.
