Initiating Circuit Wiring
Wiring diagrams for the initiating circuits are shown below. The panel supports Style B wiring for the initiating circuits
and Style D wiring for the indicating circuits. The initiating circuits are supervised by a 3.9K End-of-Line Resistor or
for power saving an Active-End-of-Line.

CAUTION:
Do not exceed power supply ratings.
Note:
According to Configuration, End-of-Line Resistors on initiating circuits must be all 3.9K ohms or all
Active End-of-Line resistors.
