6 Mapping the Cable
6.1. Mapping Directions
1 If a cable reference map (part #FM114) was not ordered from RLE Technologies, LD5100
users must create a drawing that represents the floor plan. This drawing must include the
room layout (walls, doors, and other permanent structures), the SC cable routing path, any
jumper sections of non-sensing cable (NSC) and any weighted cable connectors/simulators
(WCCS). Marking up a CAD drawing of the Facility works the best.
2 Physically identify points along the cable routing path. The points should be easily
accessible and evenly spaced. Number the points and record their location on the reference
map. Note where the connectors are located along the cable run.
3 Using the front panel of the LD5100, select Point Mapping and press Enter.
4 To test the map, wrap a wet paper towel or sponge or pour a small puddle of water around
the cable at one of the previously mapped points. The LD5100 produces a short beep within
approximately 30 seconds. The LCD displays the LD5100's calculated distance to the leak.
Remove the paper towel and dry the cable. Within approximately 20 seconds, the LD5100
produces a long beep indicating the short is removed and the system has returned to normal.
Tip If the individual mapping the cable is not in a position to hear the audible alarm, wait two
minutes between each point. This ensures the system has had time to stabilize.
Loss of power or re-entering the Point Mapping menu will cause all mapping data
to be lost (reset).
5 When mapping is complete, press the Left arrow key on the LD5100 to exit the mapping
mode.
6 Select View Map on the LCD and record the LD5100's reading of each point on the
reference map.
7 Mount the cable reference map alongside to the LD5100 control panel or the remote
display. When a leak or cable break occurs, refer to the map and the distance displayed on
the LD5100 to determine the physical location of the leak.
