4.1 Controlling Four Outputs from One Input
All four FCPS output circuits can be controlled from one control input, which in Figures
4-1a and 4-1b is illustrated as a control module. The control module can be powered
from the FCPS auxiliary 24 VDC power output (TB3 terminals 8 & 9) and supervised by
an EOL relay.
All four remote power supply outputs are shown as Notification Appliance Circuits.
Alternately, circuits 2 and/or 4 could be used as nonresettable power output circuits
which is accomplished by cutting resistors R175 for circuit 2 or R176 for circuit 4 (refer
to Figures 4-4 and 4-5).
The control module is shown to demonstrate the use of the power supply on a
multiplexed system. The control module could be replaced with any circuit capable of
polarity reversal. Note that Figure 4-1a shows Style Y configuration and Figure 4-1b
shows Style Z configuration.
