7.
At the same location the stabilizer lightly taps the
cable with the handle of a screwdriver a few times,
and then repeats the waving.
As you tap the sensor cable, you will hear the center conductor
rattle inside, as it stabilizes.
8.
Move along the sensor cable, waving and tapping
the cable as you go (at least once per meter). Listen
for the rattle, as you tap the cable. Continue
waving and tapping the cable, until you reach the
end.
It may take more than one pass of the sensor cable to ensure
that the cable is fully stabilized.
Once you can hear the rattle with each tap of the screwdriver
for the full length of the sensor cable, the stabilization is
complete.
9.
When the stabilization procedure is complete, have
both grippers simultaneously release the tension
on the center conductor.
During stabilization, the center conductor usually extends by
up to 1 m (3 ft. 3 in.). However, occasionally it may retract
toward the cable jacket. If the center conductor retracts to the
outer jacket, stop the procedure and carefully remove an
additional 15 cm (6 in.) of outer jacket and dielectric. Reapply
the tension at both ends and continue the stabilization.
If the center conductor retracts into the jacket at either end,
locate it by tapping the cable back from the end, until you
hear the rattle. Cut back the cable until the center conductor
and the dielectric are the same length. Ensure that any center
conductor that was gripped by the pliers is also removed.
Sensor cable installation guidelines
For applications that require protection for the sensor cable,
DO NOT attempt to install Intelli-FLEX cable in conduit. Use
Senstar's pre-assembled Armour-FLEX™ cable.
•
Handle the cable carefully. Sensor cable MUST NOT
be jerked, stretched, bent, twisted, knotted, kinked,
nicked, or scraped.
•
Do NOT subject the sensor cable to more than 4.5 kg
(10 lbs) of tension at any time during the installation.
•
Always apply consistent tension during the
installation.
•
Secure the sensor cable to the fence fabric at the
midpoint of the chain-link (See Figure 3).
DO NOT secure the cable at the crossing points of
the fence links.
•
The sensor cable can be mounted on either side of
the fence (site dependent).
Senstar strongly recommends installing the sensor cable on
the secure side of the fence.
•
If you require a sensor cable longer than 152 m
(500 ft.) splice two sections of Mark 2 cable together.
•
Ensure that the sensor cable is not pinched between
the fence fabric and the support posts at any point.
•
The smallest allowable bend radius for Intelli-FLEX
sensor cable is 7.5 cm (3 in.).
•
Use UV resistant nylon cable ties to secure the cable
to the fence fabric.
•
Space the cable ties every 25 to 30 cm (10 to 12 in.)
along the sensor cable.
For high security applications, or for additional security for all
applications, Senstar recommends using two galvanized wire
ties on each fence panel, in addition to the nylon cable ties.
Twist the wire ties to hold the sensor cable snugly against the
fence fabric, then flatten the twisted wire against the fence. Do
not over-tighten the wire ties, or the sensor cable response
may be affected.

IMPORTANT! The applied tension MUST be equal at
both ends of the cable.
