4 Installing the sensor cables
Cable installation overview
Optimum system performance depends on the installation of the sensor cable, and the sensor
cable connections. To install the cables and cable fittings, perform the following steps in order.
• Check the site plan and verify the cable route.
• Mark the sensor cable route on the ground and on a detailed site plan including lead-in cable,
start point overlaps, cable bypasses, decouplers, terminator overlaps.
• Check for underground utilities near the cable route.
• Dig the trenches or cut slots.
• Prepare the trenches or slots for cable installation.
• Lay the cables in the trenches or slots, inspecting the sensor cables as you proceed.
• For trench installation, partially backfill the trenches as you proceed to hold the cables in
place.
• Install connectors, decouplers and terminators.
• Test the sensor cables and connections.
• Backfill the trenches or seal the slots.
Installation guidelines
The following guidelines apply to all cable types. Information pertaining to only one cable type will
be indicated by a side heading.
To avoid problems arising from cable installation, follow the guidelines below:
• Follow the rules for burial depth, cable spacing, and cable separation from obstacles.
Note For OC2 and SC2 cables, install the TX cable on the outside of the
perimeter, and the RX cable on the inside. For SC1 cable, by
convention, use the ribbed side of the cable as the receive cable.
CAUTION The smallest allowable bend radius for all types of OmniTrax sensor
cable is 15 cm (6 in.). Any tighter bend can damage the internal foil and
compromise operation.
