CHAPTER 8: MAPPING THE CABLE
After the water leak detection cable is laid in the desired configuration, the cable can be mapped. Mapping
the cable improves the accuracy of the LD5000 and makes it easier to locate a leak.
The LD5000 computes the distance from the control panel to the leak along the length of water leak
detection cable attached to the unit. In most cases, the water leak detection cable is laid in a curved or
serpentine pattern. This may make it difficult to locate a leak when given a linear distance. To help
alleviate this problem, identify a series of easily accessible, evenly spaced points along the cable length.
Number the points, and record their locations on the leak detection reference map. Refer to the directions
below and use the numbered points to map the cable. Then, when the unit detects a leak, the location of the
leak can be determined by comparing the distance shown on the control panel with the known positions
along the cable as recorded on the reference map.
8-1 MAPPING DIRECTIONS
1) If a reference is not provided by RLE Technologies, create a drawing that represents the floor
plan. This drawing must include the room layout (walls, doors, and other permanent structures),
the water leak detection cable routing path and any jumper sections of non-sensing cable.
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.
3) Using the front panel of the LD5000:
• Select System and press Enter (↵).
• Select StartMap and press Enter (↵).
• Select Accept to start mapping and press Enter (↵).
4) To test, wrap a damp paper towel or sponge around the cable at one of the previously mapped
points. The LD5000 produces a short beep within approximately 30 seconds. The LCD displays
the LD5000’s calculated distance to the leak. Remove the paper towel and dry the cable. Within
approximately 20 seconds, the LD5000 produces a long beep indicating the short is removed and
the system has returned to normal.
5) Go to the next point and repeat the above steps until all points along the cable are mapped and
tested.
6) When mapping is complete, press any key on the LD5000 to exit the mapping mode. This
LD5000 displays Mapping Mode Off. Press any key again to save the map and return to the
System Menu.
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 stabilizer.
NOTE
The system must be calibrated prior to mapping.
