Relay Output Wiring (optional)
As illustrated in the diagram below, the Power Supply Module’s two relay outputs can be used to activate an external
alarm (TS-RA2) and the two inputs can be used to silence that alarm remotely (TS-RK).
Note: The TS-RA2, TS-RA1 and TS-RK are not part of the UL certification of this system.
Emergency Generator Applications (optional)
The wiring or use of discrete inputs is optional — skip this section if you don’t plan to use this interface. Discrete inputs
may be wired to a T5 series console with 18 AWG, type TFFN or THWN wire. You may also use THHN wire in sizes larger
than 18 AWG.
Emergency backup power generator run-relay(s) are wired to the discrete input interface terminals at the T5 series
console. A run-relay closure will stop a leak test on the associated generator fuel tank. When the generator run-
relay opens (generator stops running), a run report is produced at the console, which shows the total and hourly fuel
consumption rate during the run cycle.
Note: You must use dry run-relay contacts for this interface because the T5 series supplies +5 VDC digital logic power at
the IN (input) terminals.
Note: It is recommended that you use: IN 1 & GND for Generator 1 /fuel supply Tank #X, and IN 2 & GND for Generator 2
/fuel supply Tank #Y. The specific fuel tank(s) assigned are “programmable.” See Figure B-4 for wiring details.
