4. Installing Sensor Cable

Cable installation overview

System performance starts with the proper installation of the sensor cables.
To install the cables and cable fittings, perform the following steps in order:
•
Verify the site plans, cable routing, and note potential hazard areas from the check-list
provided earlier, such as; underground water/electrical utilities.
•
Mark the sensor cable route with
based spray paint. Chalk can be used to spray paint surfaces such as pavement,
concrete, gravel, soil, and grass.
•
Plow/dig trenches based on application and/or cut asphalt/concrete slots where
applicable.
•
Run the cables into the trenches or slots, verifying the depth every 2 m (6.6 ft) as
installing.
o Keep in mind the burial depth required for your application, cable spacing, and
distance from potential hazards
o Limit grade changes to <30°
o Make gradual sweeping turns around corners, 7 m (23 ft) radius minimum
•
Install Start-Up Module Assembly (SUMA) (includes direct bury enclosure, lead-in
cable(s), Start-Up Module(s) (SUM)
Note: Keep TX cables separated from RX cables. The TX 1/2 lead-in cables will
run together in one conduit and the RX 1/2 in the other; see
lead-in(s) will transition to TX sensor cable(s) on the protected side of the
perimeter, RX sensor cable(s) on the unprotected side.
•
Verify sensor cables with a continuity tester for shorts and grounds prior to termination.
•
Replace soil to cover sensor cables where applicable, restore asphalt removed from
trenching, and caulk any concrete slots

Cable Plow/Trenchers

Using a cable plow to install the TD100 sensor cable is the most efficient and economical
method. It helps control burial depth and width. The TD100 sensor was specifically designed for
this method. However, traditional trenching methods can also be used when installing the
TD100 Sensor Cables.
Attachments are available for adapting tractors into vibratory cable plow capable. Commercial
cable trenchers and plows are also options.
