RLE Spot Detectors - Manual (Page 2)

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.
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.
