3. The target of the DUOX development is to implement a system on two non polarized wires with digital audio that has to be in a similar cost level like VDS. DUOX will offer the functionalities of the existing systems (4+N, VDS, Bus2, MDS). The DUOX is the first full digital system in the market that requires two non-polarized wires for: power, audio, video & data transmission In this new technology, the best characteristics of the previous systems converge: MDS: High performance and great capacity. VDS: Competitive price. Wiring flexibility. BUS2: 2 non polarized wires. And the result is DUOX, a GLOBAL SYSTEM FOR ALL THE MARKETS. Its main objective is to substitute all the previous systems in a 3 years period. DUOX Technical Department Introduction

4. Features Installation Complexity 4+N Direct & City Call becomes Digital “Many Apartments” “Many Panels” (up to 7) “Thousands of apartments” “Thousands of panels” Digital MDS Duox: System of systems Historically, manufacturers have sold installation simplicity. MDS put apart the 4+N call wires, adding advanced features such as access control, electronic directory and automation. Installation complexity was kept similar to its antecesor. VDS has kept a capacity big enough to satisfy the most common installations, achieving at the same time a dramatic wiring reduction. BUS2 reduced installation to its minimum expression, offering added-value functions such as bus-command relay activation, diagnose tooling and installation simplicity. DUOX keeps the simplicity of Bus2 (2 non- polarized wires), introducing the advantages of the digital audio (Improvement of audio quality, less noises and feedback,…), and extending the capabilities of the system from villas kits to big condominiums (like MDS).

13. Main Duox characteristics The DUOX electronics allows that supply, data and audio (and video when available) are delivered in the same bus with 2 non polarized wires. Supplied with 18 Vdc for all signals via a coupling module (Minimum functional voltage 15 Vdc at terminal and amplifier). Full Digital system (Audio and commands) Two simultaneous conversation channels on the same 2 wires thanks to the multiplexing. Privacy in communications. DUOX Technical Department System Summary (9)

14. DUOX Advantages: Additionally to the advantages of the digital audio, DUOX system offers by itself other improvements in comparison with the existing systems: A more stable system regarding to signal transmission (to avoid reflections) and to achieve further distances (in the same circumstances: Type of cable, topology,…). This fact allows that devices that were required in Bus2 (as signal distributors or end of line jumpers at terminals), are no longer necessary in DUOX, as the signal transmission is more robust with respect to reflections and interferences. Only a “Line termination” will be used at last riser split to avoid reflections. As well the recognition of data is better in a digital system than in other systems like VDS where pull-up resistors were necessary due to the signal deformation because of the capacitor effect of the conductors. Two communication channels available at the same time. It collects the best features from other systems: High performance, wiring flexibility, competitive price and installation simplicity.

23. Power Supply unit + Power Filter DUOX Technical Department The riser (9) 220Vac 18Vdc 1 122 The output capacitor behaves like a shortcircuit for DUOX signals DUOX Riser Couples DC current (power) to the DUOX BUS DUOX Power Supply Filter Ref.3243 Prevents DUOX signals to traverse NET Power is coupled by mean of inductances. It is used the same filter module Ref.3243 as in Bus2. Not any power supply is valid, as the used power supply has not to introduce common noise in the DUOX bus. Fermax references: Ref.4812, 18 Vdc, 1,5 A. Version 2.0. Ref.4830, 18 Vdc, 3,5 A. Version 3.0. The DUOX signal will not leave the bus due to the high impedance presented by the filter.

24. Why not any power supply unit is valid? DUOX Technical Department The riser (10) As explained before, DUOX system requires a controlled power supply unit, that means a power supply units that does not generate high frequency noises that may be induced in the system, bloking the supply and the proper working of the installation. The high frequency noises enter in resonance with the filter, avoiding the correct working of the system.. Our power supply units Ref.4812 v.2.0 (18 Vdc, 1,5 A) and Ref.4830 v.3.0 (18 Vdc, 3,5 A) are controlled units that do not present high frequency noise. Standard non controlled power supply unit that presents high frequency noise Controlled power supply units Ref.4812 v.2.0 and Ref.4830 v.3.0 that show only the standard 50 Hz noise but no high frequency noise

The format of the tool will be like the Loft access control readers (Simple display and keypad). Same programmer tool for all DUOX devices (current and futures). The information is managed by the programmed device. Operation modes: 1._ Configurator Mode It allows programming of: Telephones (Address, melody, door matic).

The exit of configuration is confirmed by a “beep”. Following steps to select the melody for guard unit call: 1.At telephone press simultaneously the “programming” and the “door opening” button during 5 seconds: The current telephone melody for a “guard unit call” is heard. 2.Pressing sequentially the “programming” button, the rest of melodies are heard. 3.After 10 sec.without presssing any button, the last melody performed will be stored. The exit of configuration is confirmed by a “beep”. 5 Sec.

46. Pick up the handset and after few seconds automatic communication is established with panel. DUOX Technical Department Telephone (5) Just after picking up the handset, any telephone programmed with a valid address “TT TT TT” will establish communication with the panel number “0” of its block. Under the condition that there is a free channel in that block and the panel “0” is available. From this moment, the behaviour will be the same as in an accepted call (Door opening available, 90 sec.of max.conversation time,…) If this feature is not wished, just change the number of the panel to a number different from “0”. If after picking up the telephone handset, the panel “0” is in communication with other telephone or there is another telephone of the same apartment in communication, a busy tone will be heard at the telephone.
