2 Installation
2.4 Connect the SeaHawk Sensing Cable
IMPORTANT To avoid faulty leak detection readings, connect a minimum length of 35 feet (10.7m) of
sensing cable to the LD5200.
The LD5200 is shipped with a 15-foot (4.57m) leader cable. This leader cable was connected
to the LD5200 in Section 2.3.2 on page 18 . The following directions will help you connect
sensing cable to the LD5200.
2.4.1 Connect Lengths of Sensing Cable
1 Unscrew the end-of-line (EOL) terminator from the end of the leader cable.
2 Attach the first length of sensing cable to the leader cable. Insert the male connector into the
female connector, and twist the collar on the female side of the connector to secure.

3 Route the sensing cable according to your cable layout diagram. Attach additional lengths
of sensing cable as necessary.
4 Secure the EOL terminator to the unoccupied end of the last length of sensing cable.
Note If the EOL terminator is not present at the end of the cable run, a cable fault will register.
5 If you are using a reference map, compare it with the actual cable installation. Revise any
discrepancies created through the physical installation of the cable.
2.4.2 Secure Sensing Cable to the Floor
Secure the sensing cable to the floor with either J-clips (RLE part #JC), or one of the other
approved methods shown in Figure 2.5 . Available from RLE and designed specifically for use
with sensing cable, J-clips are the manufacturer's recommended installation method.
♦ Do not use conductive materials, such as Fire Block or caulk, on the sensing cable.
♦ To avoid contaminating the cable, clean the entire floor as much as possible. Use isopropyl
alcohol to clean the spots on the floor where J-clips will be placed.
♦ Place one J-clip every 5 to 6 feet (1.52 to 1.83m) along the length of the sensing cable and
one at each turn of the cable. Use more J-clips if a tighter configuration is required.
♦ If the cable is installed over an obstruction, clip the cable on both sides, as close to the
obstruction as possible.
