Simplifying a lighting control system as much as possible while offering a complete solution based on DALI2 technology, this is Duemmegi's mission with the DUELUX system.

The DALI2 system introduces a significant technological evolution of the DALI standard:

1 - First of all, the new version ensures full compatibility with existing appliances, manufactured according to the first edition of the standard.

2 - The "Multi-master" architecture is introduced which allows the insertion of multiple Master devices in a DALI system capable of sending messages.

3 - Functional standards relating to control devices (buttons, sensors, etc.) are defined.

4 - The list of DALI controls is further enhanced with some new features.

5 - The functions implemented by the lighting fixtures are further expanded, with the definition of new and innovative Device Types.

New architecture

The DUELUX solution

The architecture provides a DALI bus for communication with the ballasts/lamps (maximum 64) connected to the DLCP module; button modules, modules with digital outputs and presence and/or brightness detectors are connected on the same bus.

Figure 01 shows that the interconnection between the various DLCPs takes place through the Lan network.

DALI solution - Contatto

The architecture proposed to date

The architecture below (Figure 02) provides a DALI bus for communication with the ballasts/lamps (maximum 128) connected to the MODDALI module and a Contatto bus to which modules for buttons and presence and/or brightness detectors are connected.
Commands and lamps are linked through programming, creating the desired group and scenario turning on and off.

The DLWRX module allows interfacing up to 4 wireless transmitters with ENOCEAN technology (wireless and battery-less) with the DALI bus. Since normally each transmitter has 4 buttons, each DLWRX module can manage up to 16 points.

The only connection required for the DLWRX module are the two cables of the DALI bus; the power supply necessary for the operation of the module is obtained from the bus itself.

The coupling of a button unit to a receiver is done using the button and the two LEDs located on the lower side of the module. The DLWRX module occupies, within the DALI bus, up to 4 "control device" addresses, one for each keypad that has been combined.
