Output Circuit Trouble Mode of Operation
Overview
Output circuits include NACs, Panel Circuits 1-64, Control/Relay Modules, and Transponder Points.
This section contains a description of control panel operation for each type of output circuit.
• Four NACs are included on the control panel
• Panel Circuits include ICM-4RK, CRM-4RK, VCM-4RK or DCM-4RK panel modules via
connection to the control panel
• Control/Relay Modules connected to the control panel on an SLC
• Transponder Points include XPC (CLIP only) or XP5-C (CLIP or FlashScan).
