1.3 PRINCIPAL TECHNICAL SPECIFICATIONS OF THE DUOX SYSTEM
•Asimplifiedinstallationsystemintwo non-polar wires, which require neither floor distributorsnoroutdoor
panel switchers. This leads to a considerable reduction in installation time.
• The signal transmission (audio, video and data) is completely digital, allowing it to maximise its
capacity and robustness to noise and interference. This ensures consistent audio and video quality
throughout the installation.
• Voice-guided programming in outdoor panels and via a graphic menu on monitors.
• Substitution of a telephone with a monitor at the apartment, without requiring additional accessories.
• Line adapters are required to balance impedances.
•Privacy(completeconfidentiality)in conversations. Itisnotpossibletolistento a third-party conversation
(even between terminals installed in the same apartment).
If a conversation is underway, the system will not function for the rest of the terminals (during a pre-
established time period).
