1.1 Description
The LD5200 is a distance-read leak detection controller. It can operate as a stand-alone device
or connect to multiple RLE leak detection controllers through its Ethernet or EIA-485 ports.
When coupled with up to 10,000 feet (3084m) of RLE’s sensing cable, it reports the presence
of water and other conductive liquids. When a conductive liquid comes in contact with the
sensing cable, the following occurs:
C HAPTER
CHAPTER 0PRODUCT OVERVIEW
♦ An audible alarm sounds.
♦ The distance to the leak is shown on the LD5200’s LCD touch screen and on the LD5200’s
web interface. An integrated reference map within the web interface will also show the
location of the leak.
♦ Notification is sent via email or Modbus/SNMP/BACnet/SMTP to a central control
location, such as a building management system (BMS).
1.2 Operation
1.2.1 Supervised System
The LD5200 is a supervised system - it continually monitors sensing cable, spot detectors, and
connected leak detection controllers for continuity and produces alarms for the following
conditions:
♦ Leak detection
♦ Cable break
♦ Cable contamination
♦ Loss of communications
rletech.com LD5200 User Guide 13
1 Product Overview
1.2.2 Distance-Read Leak Detection
When the LD5200’s circuitry measures a current in excess of the user-defined leak threshold,
the unit’s microprocessor computes the distance to the leak. The LD5200 then annunciates the
leak and logs the alarm in its event log. The leak is communicated via email/Modbus/SNMP/
BACnet/SMTP/4-20mA to an equipped monitoring system. The relay output sends
notification to an alarm panel or monitoring system.
1.2.3 User Configuration and Communication
All the functionality needed to operate the LD5200 as a stand-alone device is accessible from
the LCD touch screen. Virtual buttons line the right side of the screen. Press the button for the
task you want to perform, and the screen for that task is displayed. Avoid using a pen or other
sharp object to activate the buttons on the LCD. This will damage the display.
The web-based user interface provides more extensive configuration options and allows users
to create an interactive map - a graphical representation of the monitored environment and
leak detection equipment. This web interface can be used on site or remotely via network
communications.
Digital fault and leak relay outputs and a 4-20mA relay output and allow the LD5200 to
interface with third-party management systems. The LD5200 also provides Modbus outputs
via EIA-485, twisted-pair wire, or TCP/IP, as well as BACnet/IP or BACnet/MSTP, SNMP,
and SMTP outputs.

2.4 Connect the SeaHawk Sensing Cable
IMPORTANT To avoid faulty leak detection readings, connect a minimum length of 35 feet (10.7m) of
sensing cable to the LD5200.
The LD5200 is shipped with a 15-foot (4.57m) leader cable. This leader cable was connected
to the LD5200 in Section 2.3.2 on page 18. The following directions will help you connect
sensing cable to the LD5200.
2.4.1 Connect Lengths of Sensing Cable
1 Unscrew the end-of-line (EOL) terminator from the end of the leader cable.
2 Attach the first length of sensing cable to the leader cable. Insert the male connector into the
female connector, and twist the collar on the female side of the connector to secure.
Figure 2.4
3
Route the sensing cable according to your cable layout diagram. Attach additional lengths
SeaHawk Sensing Cable
of sensing cable as necessary.
4 Secure the EOL terminator to the unoccupied end of the last length of sensing cable.
Note If the EOL terminator is not present at the end of the cable run, a cable fault will register.
5
If you are using a reference map, compare it with the actual cable installation. Revise any
discrepancies created through the physical installation of the cable.
2.4.2 Secure Sensing Cable to the Floor
Secure the sensing cable to the floor with either J-clips (RLE part #JC), or one of the other
approved methods shown in Figure 2.5. Available from RLE and designed specifically for use
with sensing cable, J-clips are the manufacturer's recommended installation method.
♦ Do not use conductive materials, such as Fire Block or caulk, on the sensing cable.
♦ To avoid contaminating the cable, clean the entire floor as much as possible. Use isopropyl
alcohol to clean the spots on the floor where J-clips will be placed.
♦ Place one J-clip every 5 to 6 feet (1.52 to 1.83m) along the length of the sensing cable and
one at each turn of the cable. Use more J-clips if a tighter configuration is required.
♦ If the cable is installed over an obstruction, clip the cable on both sides, as close to the
obstruction as possible.
rletech.com LD5200 User Guide 21
2 Installation
WARNING
♦ The J-clip’s adhesive backing does not work well on porous concrete floors. RLE
recommends using a drop of silicone or another nonconductive adhesive to help secure the
J-clip to the floor.
IMPORTANT Do not install the cable directly in front of an air conditioner. Allow a minimum of 4 to 6 feet
(1.22 to 1.83m) between the unit and the cable. If the cable is too close to the air conditioning
unit’s air stream, the moisture from the humidifier may cause false leak readings. If the cable
must be installed in front of an air conditioning unit, place the J-clips 3 feet (0.91m) apart.

2.5 Apply Power to the LD5200
A dedicated circuit breaker must be provided within close proximity to the LD5200
and be clearly marked as the disconnecting device for the LD5200 leak detection
controller.
Do not connect 120/230 VAC directly to the unit, or damage will occur to the
circuitry.
Make sure the dedicated circuit breaker is in the off position before connecting the
AC power wires to the LD5200.
1 Engage a certified electrician to run a power supply and necessary conduit to the location of
the LD5200.
2 Remove any necessary knock-outs from the bottom of the enclosure, and route the power
supply into the enclosure, to the power input terminal block. Insert the wires as noted on the
enclosure’s backplate: Neutral - Line - Ground. Ensure all connections are correct and all
screw terminals are tightened and secure.
3 Apply power to the LD5200. The device will boot (initialize).

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:
♦ 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.
Figure 2.6
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.
Apply Moisture to the Cable for Testing Purposes
24 LD5200 User Guide 800.518.1519
2.8 Calibrate Cable Resistance
Distance-read leak detection systems are resistance-based. RLE’s orange water sensing cable
has a base resistance of 2.8 ohms/foot, while most other sensing cables, including RLE’s green
chemical resistant sensing cable, have a resistance of 4.0 ohms/foot.
The resistance of each length of sensing cable may be slightly more or less than the base
resistance due to manufacturing variances. For this reason, the cable length displayed on the
home page of the web interface and on the status screen of the LCD may be slightly more or
less than the actual length of cable installed.
A system configured using base resistance values will still be very accurate. If you wish to fine
tune the resistance value of your LD5200 system to make it more precise, you may do so. This
will increase the accuracy of the system, and bring the LD5200’s reported installed cable
length value in line with the actual length of cable installed.
1 Ensure the LD5200 has been powered and has all the sensing cable attached to it, with no
alarms present.
2 Gather and record the following data from either the home page of the web interface or the
status page of the LCD:
2 Installation
Cable Length (as reported by the LD5200)
Cable Current
Leg 1 Resistance
Leg 2 Resistance
Record the resistance per foot setting, as reported by the LD5200. This can be found on the
Leak Configuration page of the web interface (Configuration > Leak Settings) or on the
Leak Settings screen of the LCD (Setup > Leak Settings).
Reported Resistance per Foot
3 Note the actual (physical + simulated) length of cable physically connected to the system.
For your reference:
♦ WCCS simulates 50 ft. ♦ XCON simulates 150 ft.
♦ SDZ simulates 50 ft. ♦ Nonsensing cable does not add
any length to a system
Record this sum:
Actual length of cable connected to LD5200
4 Verify the current reading on the cable from your recorded values above. This value must
be less than 15 μA in order to calibrate the system. If the current is higher than 15μA, clean
the cable. Isopropyl alcohol works well to remove any contamination that might have
gotten onto the cable during installation.
rletech.com LD5200 User Guide 25
2 Installation
5 To calculate the most accurate resistance value for the system, divide the reported cable
length by the actual cable length, and multiply the quotient by the reported resistance.
For example:
Cable Length (as reported by the LD5200) 391 feet
Cable Current 0 μA
Leg 1 Resistance 1088 Ohms
Leg 2 Resistance 1095 Ohms
Reported Resistance 2.800 Ohms/foot
One 15 foot leader cable (leader cable does not count toward the total length of cable
installed), one weighted cable connector (simulates 50 feet of cable), and one 330 foot
section of cable are connected to the system.
Actual length of cable connected to LD5200
380 feet
0 feet + 50 feet + 330 feet
The actual resistance of the cable installed with this LD5200 is 2.881 ohms per foot.
6 Replace the resistance per foot setting in the LD5200 with this newly calculated value. This
can be edited on the Leak Configuration page of the web interface (Configuration > Leak
Settings) or on the Leak Settings screen of the LCD (Setup > Leak Settings).
When using the web interface, remember to click the Submit Changes button to save the
adjusted resistance value.
In our example, adjusting the resistance value changed the reported cable length from 391
feet to 380 feet. This improves the accuracy of the system because the reported cable length
more closely matches the physical length of cable connected to the system.
