RE-DM4 

Radia Eclipse 4-Channel Dimmer Module (120 or 240 volts)

Overview

The RE-DM4 RADIA Eclipse 4-Channel Integrated Dimmer Module (120 VAC: 

FG706-01

; 240 VAC: 

FG706-02

) controls up to six circuits with four 1200-watt onboard 

dimmers and two satellite connectors for RDM series dimmer or switch modules 
(FIG. 1). The RE-DM4 is designed for use with the RDA series of enclosures in an 
AMX Lighting™ modular digital dimming system. The RE-DM4 is controlled by AXLink 
or by dry (contact) closures.

Caution: Pre-Installation Notes

WARNING

: This unit should be installed only by qualified electrical personnel, and in 

compliance with all national electrical codes, local codes and ordinances.To prevent 
possible personal injury or death, disconnect power to the enclosure 

at the breaker 

box 

before attempting to work with any AMX Lighting modules.

All Class 1 and 2 wiring must be connected to their dedicated terminals.

Class 1 wiring should be connected through the top of the enclosure, and Class 

2 wiring through the bottom.

Load conductors must be same size as line conductors, regardless of 

connected load.

Disconnect power while installing or connecting the unit.

Keep top and bottom air vents clear at all times, and maintain 12” (30.48 cm) 

clearance around the top and bottom.

Test loads for shorts before connecting.

Class 2 wiring must be rated 300V or higher.

For indoor use only.

AC lighting loads only.

This module may require extra power from the AXLink connection or an external 

power supply connected to the control card.

For more information, refer to the RE-DM4 instruction manual available at 

www.amx.com

.

Radia Lighting System Configuration Pages

The AMX Radia Web pages provide a simple interface for users of the Radia Duet 
module. The web pages reside on the AMX master when running the Radia Duet 
module and may be accessed through Internet Explorer or Mozilla Firefox. The RE-
DM4 may also be configured using NetLinx code or a terminal. For more information, 
refer to the RE-DM4 instruction manual available at 

www.amx.com

.

High-Voltage Connections

Each AMX Lighting module has its high-voltage connectors marked on its circuit 
board. Line, load, and neutrals are also clearly marked.

Line-in Connections

Using two feeds for Line 1 and Line 2 provides two 2400 W inputs.

With a jumper, Line 1 and Line 2 provides a single 2400 W input (FIG. 3).

Dry Contacts

• Emergency fire alarm relay connection - Closed relay 

activates preset 126. Other control is locked out until 

relay opens. Supports daisy chaining of up to 20 

dimmers for this connection, with a maximum current 

requirement of 200mA when daisy-chained.

• Failsafe connection - Works with a toggle switch - 

opening the switch triggers preset 128, closing the 

switch triggers preset 127. Supports daisy chaining of 

up to 20 dimmers for this connection with a maximum 

current requirement of 200mA when daisy-chained.
