Follow these steps monthly to test the SeaHawk 10K and ensure that the device is functioning
properly. If your SeaHawk 10K is hooked into a BMS or NMS, notify monitoring personnel
before you begin to test the system.
1 Place water on the cable - either dip the cable into a cup filled with water, wrap the cable
with a wet cloth, or pour a puddle of water onto the cable.
2 Verify the “leak detected” alarm on the control panel.
3 Compare the distance reading on the SeaHawk 10K to a reference map (if available) to
ensure the SeaHawk 10K displays the correct leak location. See Chapter 4 on page 35 for
more information about calibrating the leak detection cable.
4 Dry the cable and verify the SeaHawk 10K returns to normal.
5 Remove the End-of-Line terminator (EOL).
6 Confirm the “cable break” (
cbr
) alarm on the SeaHawk 10K.
7 Reinstall the EOL.
8 Verify the SeaHawk 10K returns to normal.
9 Monitor the cable current monthly to ensure the cable is not being contaminated. The
SeaHawk 10K will alarm if the contamination is excessive.
10 Monitor the cable current. If the cable current is greater than 15 μA, troubleshoot the cables
to determine which cable is contaminated. The contaminated cable should be removed,
cleaned, and retested.
