RADIA Lighting Control System
Low-Voltage Connections
The low-voltage area in the AMX Lighting controllers contain connections and DIP switches for AxLink,
PROlink, dry closures, and module jack connectors. On the controller cards, low-voltage power for the board
is supplied either by line power, optional auxiliary power supply (RDA-PSM), or the +12 VDC pin on the
AxLink connector.
There is also a green status LED on the controller circuit board that blinks, according to the current operating
status of AxLink and red LEDs, one for each of the external connectors for additional modules.
Figure 18 shows an example of the low-voltage connections, DIP switches and LEDs using the RDD-DM4
controller.
All low-voltage connections must comply with Class 2 wiring codes.
