DUOX System

this is the first completely digital system in two-wire non-polarized technology. This is the most technologically advanced system in the world, allowing fast installation with just two wires. The most highly simplified and advanced installation system on the market. It maximizes intercom system capacities thanks to digital audio and video transmission.

Duox offers maximum ease of installation, enabling transmission of all signals: power feed, audio, video and data with the highest capacities. It permits management of

  • From 1 to 999,999 apartments:
  • Calls from pushbutton panel: 99.
  • Calls from keypad panel:
  • Sub-block: 99.
  • Block: 9999.
  • General entry: 999999.
  • From 1 to 10 panels:
  • Number of panels:
  • General entry: 10.
  • Block: 10.
  • Sub-block: 10.

The maximum distance will depend on the installation topology and cable. See table of sections and distances for more details. DUOX offers maximum versatility thanks to the stability and strength of signal transmission in this fully digital system which avoids possible feedback and interference in the installation.

The DUOX amplifier includes a voice synthesizer. Operating the lock release issues a message: “door open, close after entry”. Up to three terminals (telephones/monitors) can be installed in each apartment. Apartment terminals require simple programming. This programming assigns a call code to each terminal. Communication is private.


Any type of cable may be selected: parallel, twisted pair and UTP CAT5 in new installations; even existing cables in replacement work can be used (5 wires, 2-wire bell or old 4+N wire).

Non-polarized 2-wire. Please check the sections-distances-terminals-power supply table.
