3.4 CLASS "A" OPERATION

Class "A" circuit 1 uses "OUT1" and "OUT3". Class "A" circuit 2 uses "OUT2" and "OUT4". When operating in Class "A" the
two circuits must have the same switch settings for the operational mode selected. Switches SW1 and SW2 on the logic board are
in the "CLOSED" position.
•
IN1 and/or IN2 can be used for connection to the FACP. The INPUT SELECT Switch (4) selects which input is to be used
to activate the output.
•
Logic Board switches SW1 and SW2 control Class "A" or Class "B" configuration. SW1 controls Outputs 1 and 3. SW2
controls Outputs 2 and 4.
•
DIP Switch settings for each circuit in the Class "A" output must be set identically.
