Follow these steps monthly to test the system and ensure that the control panel is functioning
properly:
1 Place water on the cable.
2 Verify the Leak Detected alarm on the control panel.
3 Compare the distance reading on the LD5200 LCD to the reference map to verify that the
LD5200 displays the correct leak location.
4 Dry the cable and verify that the LD5200 returns to normal.
5 Remove the end-of-line terminator.
6 Verify the Cable Break alarm on the control panel.
7 Reinstall the end-of-line terminator.
8 Verify that the LD5200 returns to normal.
Monitor the cable current monthly to verify that the cable is not being contaminated. The
LD5200 will alarm on cable contamination if the contamination exceeds the cable
contamination threshold.
1 From the LD5200’s LCD, press the Status key.
2 Ensure the cable current is less than 15 μA. If the cable current is greater than 15μA, one of
the cables is contaminated. Refer to Appendix D, “Troubleshooting” on page 109 to
troubleshoot the cables and determine which cable is contaminated. The contaminated cable
should be removed, cleaned, retested and reinstalled.
