WIRE SPECIFICATION AND INSTALLATION
Connecting the Two-Wire Paths
1. Turn Controller power OFF.
2. Route the red and blue wire paths from the eld up through
the wire openings or conduit into the controller wiring
compartment.
3. Connect the red and blue two-wire paths to the decoder
output screw terminals below the decoder module.
4. There are two rows of screw terminals in the controller that
are accessed through an opening in the decoder module
cover, one red and one blue, labeled 1-2-3. Each numbered
pair represents a possible two-wire path to the eld (some
systems only use one pair, others may use all three).
5. Connect the red wire from a twisted pair to a numbered red
terminal, and connect the blue wire to the blue terminal
with the same number. Do not connect more than one wire
to any of the terminals. Do not mix red from one pair with
the blue from another pair. Keep each pair separate, red to
red and blue to blue, until all pairs are connected to their
numbered terminals.
6. Turn controller power back ON and test. The decoder
output module display should show that it is ready for
programming or operation.
NOTE: If decoder(s) have not been installed on
the two-wire path(s), the decoder output
module will display “Line Open”.
