RLE Spot Detectors User Manual
Spot Detector Quick Start Guide
designed for use with SD, SD-Z1, SD-Z, and SD-RO1 products
SD
The SD is designed to primarily function with RLE controllers, specically the
FMS, F-series, RA1x2, or the LDRA6. The SD functions like a switch - the circuit
remains open until a leak is detected. The sense probes detect a leak, which
causes the circuit to close, which then triggers an alarm. If the SD is operating
on 12-36VAC power, the circuit will reset and open automatically once the leak is
no longer present. If the SD is operating on 18-36VDC power, the circuit must
be manually reset after the leak is cleared. To do this, you must break power
to the device, which will reset the circuit. Even if the water leak is no longer
present, power must be broken to manually reset the DC-powered SD.
Thank you for purchasing a SeaHawk spot detector. This guide describes how to
install all models of spot detectors available from RLE Technologies.

General Installation Instructions
While the instructions to mount each spot detector to the oor are the
same, each model of SD connects differently with its controller. Follow these
instructions to mount your spot detector to the oor; then continue to the
directions specic for your SD.
1. Determine the spot detector’s location
2. The angle of the sense probes can be adjusted to change the sensitivity of
the SD. The closer the probes are to the oor, the smaller the quantity of
water required to trigger the sensor. Adjust the sense probes to the desired
height. Be sure the probes don’t touch each other.

Probes
The SD comes with a two-wire open lead that allows it to be wired directly to
the controller’s terminal block. Connect the white/red and black leads to the
appropriate terminal blocks on the controller.

SD-Z1
The SD-Z1 is a single zone spot detector, designed for zone leak detection
systems including the LD300, LD1000, and LDRA6. RLE recommends using only
one SD-Z1 per zone.
The SD-Z1 comes with a four-wire open lead that allows it to be wired directly to
the controller’s designated terminal block. Connect the four wires - red, green,
black, and white - on the SD-Z1 to the terminal block on the controller.
This sensor will alarm with a small
quantity of water present.
This sensor requires a larger amount of
water to be present before it alarms.
3. Ram set 6/32 threaded studs in the oor on 2.5” centers or apply mastic.
4. Place the spot detector over the studs or mastic and secure.
From this point, each spot detector’s installation varies a bit. Refer to the
instructions for your particular unit.
SD-Z1
SD-Z
Designed to work with either zone or distance-read leak detection controllers,
the SD-Z can also be connected to other SD-Z units or to sensing or non-sensing
cable. When used with a distance-read system, the SD-Z simulates 50 feet of
cable - 25ft. (7.62m) from the male connector to the SD-Z, and 25ft. (7.62m)
from the SD-Z to the female connector.
Because a SD-Z cannot connect directly to a controller, leader cable and an EOL
terminator are required for installation. RLE packages these components as
an LC kit. If you’re adding the SD-Z to an existing RLE leak detection system,
additional leader cable and EOL may be unnecessary. Please check your supplies
before you attempt to install the SD-Z.
When you connect RLE leak detection components, the male pins in the
connectors should always point toward the controller. Therefore, connect the
black connector with the pins to the control head, and place the EOL on the
connector without pins.
SD-RO1
The SD-RO1 is a single zone spot detector with one generic relay output. It can
be used in conjunction with any product that accepts a digital dry contact input.
The SD-RO1 requires an isolated power supply, either RLE part number
PSWA-DC-24 or WA-AC-24-ST. These power supplies are sold separately and are
available from RLE.
If the SD-RO1 is operating on 24VAC power, the circuit will reset and open
automatically once a detected leak is no longer present. If the SD-RO1 is
operating on 24VDC power, the circuit must be manually reset after a leak is
detected and cleared. To do this, you must break power to the device, which
will reset the circuit. Even if the water leak is no longer present, power must be
broken to manually reset the DC-powered SD. The easiest way to accomplish
this manual reset is to install a reset switch on either the positive or negative
wire of the power supply that feeds into the SD-RO1.
To connect the SD-RO1 to a controller:
1. Connect the white (N/O) and green (Common) or blue (N/C) leads to the
alarm device.
2. Connect the black (-) and red (+) leads to the power source.
If the SD-Z is being added to an existing system - connected in a chain with
other SD-Z devices or cable - undo the appropriate coupling, insert the SD-Z into
the chain, and secure all connections.
