Follow these steps monthly to test the system and ensure that the control panel is functioning
properly:
1 Place water on the cable.
1 Verify the Leak Detected alarm on the control panel.
2 Compare the distance reading on the LD2000 to a reference map (if available) to verify that
the LD2000 displays the correct leak location.
3 Dry the cable and verify that the LD2000 returns to normal.
4 Remove the End-of-Line terminator (EOL).
5 Verify the Cable Break alarm on the control panel.
6 Reinstall the EOL.
7 Verify that the LD2000 returns to normal.
8 Monitor the cable current monthly to verify that the cable is not being contaminated. The
LD2000 will alarm on cable contamination if the contamination is excessive.
9 From the LD2000 Web interface, verify that the Cable Current is less than 25  A. If the
cable current is greater than 25  A, it is recommended to troubleshoot the cables to
determine which cable is contaminated. The contaminated cable should be removed,
cleaned, retested
