Question Answer
My water leak
detection cable
touches metal
surfaces. Is this a
problem or a potential
problem?
In general, no. The two water sensing wires are covered by a
nonconductive polymer weave. This weave isolates the cable from
metal surfaces. However, as with all electrical wires and cable,
avoid sharp objects that can slice or pierce through the insulation
and nonconductive polymer weave.
The sensing cable is
routed so that it has to
cross over itself. Can
this cause false
alarms?
Crossing sensing cables will not cause false alarms, but it can
cause a false distance reading if a leak occurs at the crossover
point. If the cables must cross, use a 10 foot section of non-sensing
cable to jump over the section of sensing cable.
If I suspect a bad
section of sensing
cable, how can I verify
that it is ok without
sending it back to RLE
for warranty
evaluation?
It can be very difficult to remove sensing cable, so verify the cable
is working before you attempt to remove it and return it to the
manufacturer. Use either a cable tester (RLE part # LDCE) or refer
to the Cable Break Alarm assessment in Table D.1, “Troubleshoot
Problems with the LD5200” to determine which section of cable
may be faulty.
How do I secure
sensing cable to the
floor?
RLE recommends the use of J-clips. J-clips are nylon cable clips
with a self-adhesive backing. J-clips hold sensing cable securely in
place without pinching or binding the cable, which can cause false
alarms.
J-Clips should be placed 5 to 6 feet apart throughout an installation,
and 3 feet apart when cable is routed in front of CRAC units.
Because the J-clip’s adhesive backing does not work well on
porous concrete floors, apply a drop of silicone or another
nonconductive adhesive to help secure the J-Clip to the floor.
