on the hinged side of the gate, the split loom prevents the cable from rubbing against the edges of
the conduit and the gear clamps are used to secure the conduit to the fence post. The conduit
must have notches cut at any points where gate hardware is attached to the post, so the conduit
can fit flush against the fence post.
Protecting masonry walls and buildings
If some, or all, of the perimeter is comprised of masonry walls or buildings, FiberPatrol sensor
cable can be installed along the outside edge, and if necessary, the inside edge of the structure to
protect against climb over intrusions. In this case, custom P-brackets are used to fasten the sensor
cable to the structure so it extends slightly outside and above the structure. A P-bracket is installed
every 50 cm (20 in.) along the structure to hold the sensor cable in place.
For a masonry wall, the recommended sensor cable configuration uses 2 cables. One along the
outside edge and one along the inside edge.
Note
FiberPatrol functions as a contact sensor when it is installed on
masonry walls and buildings.
