Supplies for Installation
Included with the LD300
15 foot (4.57m) leader cable
End-of-line terminator (EOL)
Wall mounting hardware
Available from RLE, sold separately
SeaHawk sensing cable, up to 300 feet (91.4m)
100-240V to 5VDC power supply (WA-DC-5-ST)
Mount the Device
Remove the cover from the LD300 to expose the mounting holes. Use the
provided hardware to mount the LD300 in the desired location.
Connect the Sensing Cable
Leader cable is used to connect sensing cable to the LD300, since sensing cable
cannot connect directly to the device.
1. Insert the four stripped wires of the leader cable into the appropriate slots in
the Cable Input terminal block at the bottom right corner of the LD300:
White wire: insert into pinout labeled
W
Black wire: insert into pinout labeled
B
Green wire: insert into pinout labeled
G
Red wire: insert into pinout labeled
R
2. Unscrew the EOL from the end of the leader cable.
3. Attach the length of sensing cable to the leader cable.
4. Route the sensing cable according to your cable layout diagram.
5. Secure the EOL to the unoccupied end of the sensing cable.
Connect the Relay Outputs
The LD300 can be used as a stand-alone device, but it does have two Form
C relay outputs that communicate leak and fault status to another device or
system. If you wish to use the relay outputs, wire them at this time.
Connect the Power and Wiring Connections
The LD300 requires a 5 VDC power supply. To avoid product damage or personal
injury, wire power to the slots labeled
+
and
–
in the DC IN terminal blocks.
Establish all wiring connections, including sensing cable, relay outputs, and
power before you activate the board’s power supply.
Program Jumpers
The LD300 has two sets of three-pin jumpers. JP1 is used to configure the
sensitivity of the leak setting. JP2 configures the relay outputs. If you change
the jumpers, you must cycle power to the LD300 in order for it to recognize the
change.
JP1
Set the leak sensitivity
Jumper spans top two pins
High sensitivity - most sensitive - system alarms with
.5” (13mm) wetted cable
Jumper is not installed
Medium sensitivity - system alarms with 2” (51mm)
wetted cable
Jumper spans bottom two pins
Low sensitivity - least sensitive - system alarms with 6”
(152mm) wetted cable
JP2
Relay Output Configuration
Jumper spans top two pins
Relay is supervised
Jumper spans bottom two pins
Relay is non-supervised
LED
The LD300 has one LED, which is used to report a variety of device conditions.
Power On / Normal
- The LED is on and displays a solid green color during
normal operation, with no alarm present.
Cable Break
- The LED flashes twice and then pauses for two seconds. This
pattern repeats itself as long as the cable break is present.
Leak
- The LED flashes constantly, one second on, one second off. This pattern
repeats itself as long as the leak is present.
