2.7 Test the System
Note If the LD5200 is already connected to a BMS or NMS, notify monitoring personnel before you
begin testing the system.
1 Using a sketch or mechanical drawing of the facility, add the cable routing, connection
points, and any accessories used. Record the distance marker when the cable changes
direction and in between connectors.
The more details you show, the greater the benefit later when you are locating leaks and
troubleshooting the system
2 To verify the LD5200’s accuracy, test three points within the length of sensing cable - one
at the beginning, one in the middle of the length, and another near the end of the length of
cable.
There are a variety of ways to simulate a leak:
3 Verify that the LD5200 reports the leaks within a few feet of their actual physical location.
4 Remove the simulated leak source and return the system to its normal operating state.
♦ Pour a small puddle of water on the
cable while it rests on the floor.
♦ Dunk the cable in a cup of water.
♦ Soak a paper towel or rag and wrap it
loosely around the cable. This is
popular if the cable is used in pipe
applications. Be careful to wrap the
wet cloth loosely around the cable.
Do not put pressure on the cable.
IMPORTANT - To avoid inaccurate
readings, do not grip the cable with
your hand.
