1.1. Description
Figure 1.1
LD2100 Leak Detection and Communication
The LD2100 is a complete monitoring system that reports the presence of water and other
conductive liquids.
The LD2100 is an advanced controller that operates in conjunction with SeaHawk sensing
cable and SeaHawk spot detectors. Each LD2100 monitors up to 5,000 feet (1524m) of
sensing cable. When a conductive liquid comes in contact with the sensing cable or spot
detector, the distance to the leak is shown on the LD2100's front panel display.
C HAPTER
CHAPTER 0PRODUCT OVERVIEW
Alarm notifications are distributed via user-configurable Modbus (EIA-485 or TCP/IP),
BACnet (IP), SNMP, SMTP (email), or relay output to an alarm panel.
rletech.com LD2100 User Guide 11
1 Product Overview
1.2. Operation
Supervised System
The LD2100 is a supervised system — it continually monitors the leak detection cable and spot
detectors for continuity. In addition to a leak triggering an alarm condition, a cable break or
excess contamination of the cable causes a cable fault indication and activates a relay. The
LD2100 sends alarm notifications to predetermined recipients when an alarm sounds. The
LD2100 produces an alarm during the following conditions:
♦ Leak detection
♦ Cable break
♦ Cable contamination
Distance-Read Leak Detection
When the LD2100's circuitry measures a current in excess of the user-defined leak threshold,
the unit's microprocessor computes the distance to the leak. The LD2100 then annunciates the
leak and logs the alarm in its event log. The summary relay has one output.
User Communication
A Web-based user interface provides information about the LD2100’s conditions. The user
interface can be used on site or remotely via network communications. The chapters and
appendices in this manual describe how to use the interface to accomplish specific
configuration and operation tasks.
The LD2100 also provides Modbus outputs via EIA-485, twisted-pair wire, or TCP/IP, as well
as BACnet/IP or BACnet/MSTP and SNMP outputs.
12 LD2100 User Guide 800.518.1519
Installing the LD2100 involves mounting it to a wall in the appropriate location and making
the necessary connections for power, leak detection, and communications.
2.1. Prepare for Installation

Item Description
Digital LED display
• In a normal operating state, this LED displays the
product name with a spinning bar (
|
) to the right of the name.
LD2100
• In an alarm state, the LED displays information about the
alarm condition; for example, if a leak is detected, the LED
displays a message with a leak detection cable distance
included. For example:
Leak detected
250 uA
at 675 ft (or 205.74m)
Note: Current range for a leak: 235 – 302 uA
Status LED Green: The LD2100 is powered on and in a normal operating state.
Red: The LD2100 is in an alarm state.
Test/Reset button If an alarm is sounding, briefly pressing the button turns off the
audible alarm. The Status LED remains red, and the digital LED
display continues to show the alarm condition.
In an alarm condition, whether the alarm is sounding or not,
pressing and holding this button clears the alarm.
In normal operating conditions, pressing the Reset button
causes the display to cycle through four lines:
LeakageC
nnnn uA
Length
nnn ft (or nnn m)
After a short pause, the LD2100 returns to the default display or

2.3. Physical Connections
The LD2100 has the following physical connections:
2 Installation
Figure 2.1
LD2100 Connections
TB1: Input Power
Power can be wired to the LD2100 through TB1. Wire the connections as follows:
TB1-1 24VDC positive (+)
TB1-2 24VDC negative (-)
P1: Input Power
RLE recommends powering the LD2100 with 24VDC wall adapter power supply. This power
supply can be purchased directly from RLE, and is offered as RLE part #PSWA-DC-24. P1 is
the connection for this power supply.
To learn more about connecting power to the LD2100, refer to Section 2.6., “Apply Power to
the LD2100” on page 19.
TB2: Cable Interface
SeaHawk sensing cable connects to TB2. Since sensing cable cannot connect directly to a leak
detection controller, the 15-foot (4.57m), non-sensing leader cable (supplied with the LD2100)
must be connected to TB2, and then the sensing cable connected to the leader cable; see
Section 2.5., “Connect the SeaHawk Leak Detection Cable” on page 17.
TB3: Summary Relay
Terminal TB3 is a Form C summary relay output. This relay provides alarm notification when
a leak, cable fault, or cable contamination is detected.
rletech.com LD2100 User Guide 15
2 Installation
The three contacts on TB3 are labeled NO, C, and NC. Connect the alarm relay wires to TB3
as follows:
TB3-1 Leak alarm normally open (NO)
TB3-2 Leak alarm common (C)
TB3-3 Leak alarm normally closed (NC)
Both relays (all alarms) can be configured to be latched or unlatched. A latched alarm requires
a manual reset of the system once a leak or cable problem is no longer present.
P4: EIA-232 Connector
The EIA-232 uses a baud rate of 9600. The EIA-232 port is set to 8 databits, no parity, and 1
stop bit (8, N, 1). A straight through cable should be used to connect a terminal or PC to the
LD2100. This connection should only be used for setting the IP address, using advanced
diagnostics, uploading firmware, and troubleshooting. Detailed IP configuration instructions
can be found in Section 2.7., “Configure Communication through the Ethernet Port” on
page 20.
SW3: EIA-485 Termination
Switch SW3 is used when the LD2100 is the last unit on a EIA-485 network. Switch SW3 on
(push to the down position) to place a termination resistor across the + and - terminals of the
EIA-485 port.
TB4: EIA-485 Modbus Port
TB4 connects to an EIA-485 network. A grounded shield contact is provided for connection to
shielded cable. If the shield contact is used, verify the power connector is properly grounded
and there is no voltage potential between units on the network. The EIA-485 port has a
selectable baud rate (9600, 19200, or 38400) and is set to 8 databits, no parity, and 1 stop bit
(8, N, 1). Connect the EIA-485 wires to TB4 as follows:
TB3-1 A (+)
TB3-2 B (-)
TB3-3 Shield
P3: RJ45 Network
A 10/100 BaseT Ethernet connection allows the LD2100 to connect directly to a local area
network. Use a crossover cable (shipped with the LD2100; blue cable with yellow ends) for
initial connection and configuration. The default settings are as follows:
IP Address: 10.0.0.188
Subnet Mask: 255.255.255.0
2.4. Mount the LD2100
The LD2100 is a wall mounted device. Using the wall mount kit (screws and reinforcers,
included) or the LD-ENC wall-mountable enclosure (sold separately), mount the device to the
wall in a convenient location.

Figure 2.3
SeaHawk Sensing Cable
2.5. Connect the SeaHawk Leak Detection Cable
The LD2100 is shipped with a 15-foot (4.57m) leader cable. Since sensing cable cannot
connect directly to a leak detection controller, one end of this leader cable connects to the
LD2100 controller, and the other end connects to the SeaHawk sensing cable. Connect each
end of the leader cable as follows:
1 With the screws of terminal block connector TB2 on the LD2100 facing up, connect the
four stripped, bare wires of the leader cable to the terminals in this order, from left to right:
white, black, green, red.
Note If the terminal connector is removed from the end of the cable, make sure the wires are in
this same order when the connector is reapplied.
2 Unscrew the end-of-line (EOL) terminator from the other end of the leader cable.
3 Attach the first length of sensing cable to the leader cable.
4 Route the sensing cable according to a cable layout diagram. Attach additional lengths of
sensing cable as needed.
5 Secure the EOL terminator to the unoccupied end of the sensing cable.
rletech.com LD2100 User Guide 17
2 Installation
Figure 2.4
Secure the Cable
Note If the EOL terminator is not present at the end of the cable run, a cable fault will register.
If you are using a reference map, compare it with the actual cable installation. Revise any
6
discrepancies created through the physical installation of the cable.
2.5.1 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 2.4. 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 the 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.
♦ 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 36 inches (0.91m) apart.

2.9. 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 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 LD2100 system to make it more precise, you may do so. This
will increase the accuracy of the system, and bring the LD2100’s reported installed cable
length value in line with the actual length of cable installed.
1 Ensure the LD2100 has been powered and has all the sensing cable attached to it, with no
alarms present.
2 Gather and record the following data from the home page of the web interface:
Cable Length (as reported by the LD2100)
Cable Current
Leg 1 Resistance
Leg 2 Resistance
2 Installation
Record the resistance per foot setting, as reported by the LD2100. This can be found on the
Leak Configuration page of the web interface (Configuration > 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 LD2100
4 Verify the current reading on the cable from the recorded value 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.
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.

2 Installation
For example:
Cable Length (as reported by the LD2100) 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 LD2100
380 feet
0 feet + 50 feet + 330 feet
The actual resistance of the cable installed with this LD2100 is 2.881 ohms per foot.
6 Go to the Leak Configuration page (Configuration>Leak Settings) and enter the newly
calculated Resistance Per Foot value. Click Submit Changes once you have made all your
changes to this web page.
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.

2.10. Test the System
Now that the system is calibrated, test a few spots before mapping the system.
Note If the LD2100 is already connected to a BMS or NMS, notify monitoring personnel before you
begin testing the system.
1
To verify the LD2100’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:
2 Installation
♦ 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 2.8
2 Verify that the LD2100 reports the leaks within a few feet of their actual physical location.
3 Remove the simulated leak source and return the system to its normal operating state.
Apply Moisture to the Cable for Testing Purposes
