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
Class 2 wiring 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 REDM4 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.

Low-Voltage Connections

The low-voltage area in the AMX Lighting controllers contain connections and DIP switches for AXLink, dry closures, and RDM module 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. AXLink address DIP switch Module connector/LED (CH6) Module connector/LED (CH5)
Each dry contact closure has two pins: ground and contact. To activate each dry closure, connect the ground and contact.
Setting AXLink Address Numbers
Set the AXLink address number (1-255) for the RE-DM4. This number must match the device number in your Axcess program. Note: By turning all switches off, all circuits will go to 100 percent so that the installer can test the high-voltage connections without having connections to a control system.

Connecting AXLink

Connect the 4-pin captive-wire AXLink from the RE-DM4 to the Central Controller for AXLink control of the dimming system. AXlink connector Dry contact closures Auxiliary power IN RE-DM4 PWR AXP AXM GND PWR AXP AXM GND Central Controller

Dry Closure Connections

Dry contact closures from other equipment can be connected to the Radia Eclipse dimmer module to provide direct manual control of lighting loads (FIG. 5). FAILSAFE GND EMERGENCY GND Failsafe switch Alarm system
