Figure 8: OCAC-304/302 Output Class-A Converter Adder Module
Indicating circuits must be wired from the OCAC-304/302 to the main Fire Alarm board. For example indicating
circuit 1 positive (red wire) and negative (black wire) is wired from the Class A converter module to the positive and
negative terminals of Indicating circuit 1 on the Main Fire Alarm board.
The actual indicating zone is wired from the SIGNAL OUT positive and negative to the signaling devices and then
wired back to the SIGNAL RET positive and negative.
