FiberPatrol Site Planning & Installation Guide
•
form the sensitivity loops
•
create a 10 m service loop on the hinged side(s) of gate
•
create 13 m isolation loops (if required)
1. Refer to the site plan and lay out a sufficient amount of sensor cable in a figure 8 pattern.
2. Loosely attach the sensor cable to the post on which the gate is hinged. Attach the sensor
cable to the gate at ¼ the fence height, 30 cm away from the outside edge, and ¾ of the fence
height.
3. Hold the conduit against the fence post and on the conduit, mark the positions of any
hardware on the fence that will require notches in the conduit.
4. Make any required notches in the conduit.
5. Place the notched half of the conduit under the cable against the fence post and hold it in
place.
6. Press-fit the sensor cable into the split loom so the split loom extends 7.5 cm (3 in.) beyond
the top and bottom of the split conduit.
7. Fit the other half of the conduit over the split loom and cable and secure the conduit to the
fence post with the supplied gear clamps. Ensure the split loom covers the sensor cable, and
protects it from chafing against the top and bottom edges of the conduit.
8. Form a sensitivity loop and attach the sensor cable to the fence panel leading up to the gate.
9. Form a sensitivity loop and attach the sensor cable to the fence panel leading away from the
gate.
Masonry walls and buildings
To install sensor cable on masonry, P-clamps are used to secure the cable so it extends about
5/8 in. past the edge of the wall and 5/8 in. above the height of the wall. The P-clamps are attached
to the masonry surface every 60 cm (2 ft.). Adjust the spacing of the P-clamps at any changes in
direction (horizontal or vertical) to ensure the minimum bend radius of the sensor cable is not
violated. Follow standard masonry fastening procedures approved for light to medium duty
applications.
The P-clamps are 2.5 in. galvanized steel, and are designed to be anchored with a single screw.

service loop
attach the cable securely on the gate panel
and the fence fabric leading up to the gate
do not attach the sensor cable in the sections
that rotate when the gate is in use
center the split conduit on the post and ensure the split loom
extends slightly above and below the ends of the conduit
