Cable splices

Terminators in slots
To terminate the ends of an OmniTrax perimeter in concrete slots, you must widen the slots for
approximately 6 m (19.5 ft.) to provide maintenance access and accommodate the decouplers and
terminator assemblies. To make a closed perimeter in slots you overlap the two cable sets by 4 m
(13 ft.) at the decouplers as indicated in Figure 122:
.
Cable splices
Required equipment
• cable set splice kit
• OC2 - A4KT0604
• SC1 - A4KT0601
• SC2 - A4KT0602
• (for a cable bypass) non-detecting cable, the length of the bypass
non-detecting cable is available in lengths of 25 m (82 ft.), 50 m (164 ft.), 100 m (328 ft.)
• one section for SC1 sensor cable
• two sections for SC2 sensor cable
• two sections for OC2 sensor cable
• cable set tool kit (SC1, SC2 - A0KT1500, OC2 - A4KT0200)
• heat gun
Points to remember
• cut out the section of cable that is being replaced (if a 20 m bypass is being installed, you must
remove 20 m of detecting cable)
• label and store the removed cable (e.g., detecting OC2 - 150 m to 165 m)
• cut the replacement cable slightly longer than the length of cable that has been removed
• for a cable bypass install the ferrite beads on the non-detecting cable before you install the
connectors
• buried connections must be covered with heatshrink that contains a sealant compound

Note Connect the replacement cable to one side of the splice, and then cut to
fit where it meets the second side of the splice. Extra cable can be laid
in a lazy-S pattern to provide strain relief for the splice connections.
