divided according to the functions described in the table below, are used to make all the connections from
and to the video door entry unit.

Another advantage of using the Due Fili (Two-Wire) system is the extreme flexibility in the event of expanding
the system at a later date; it is possible to add new indoor stations by simply using the pillar without having to
wire additional cables to the power supply.
The digital management of all the commands (ringtone duration, type of ringtone, call duration, answer dura-
tion, entry with password or programmed key, etc.) allows all the parameters for devices to be programmed to
meet individual users’ needs.
Main technical characteristics of the system.
• All the system elements are connected via bus with 2 wires that are twisted and not polarized
• Up to a total of 200 users, comprising audio and video door entry units
• Up to 15 entrance panels, audio and video
• Recommended cable art. 732H (for indoor installation), art. 732I (for underground installation with drainage
channel), art. LSZH (or LS0Z) or a cable of equal or higher characteristics.
• Up to 16 independent pillars
• Up to 16 auxiliary functions in the same system
• Audio and video door entry units with confidential conversation
• Audio intercom between indoor stations
• Different call tones for entrance panel, landing and intercom

• Group video door entry call with only the master switching on (with no supplementary power supplies) or with
all the video door entry units of the group switching on at the same time (with supplementary power supplies
starting from the third video door entry unit)
• Simple programming of the devices for the standard functions via panel and device buttons
• Advanced device programming with a personal computer (PC), USB interface 692I/U and "EVCom" software
