MAIN FEATURES

Power supplies and service modules
Power supplies
These items provide power to the DUO system and are the only ones
in the entire system that must be connected to the mains supply. During
the design phase it is necessary to provide for a single mains switch in
order to ensure the disconnection of the mains voltage to the entire
system for maintenance. Furthermore the electrical line and the DUO
line must be routed in different conduits with a distance of at least 10cm
between them.

Video distributors
They distribute the video signal to the various video intercoms and
intercoms of the DUO video intercom system. Each derived output
connects a video intercom (or intercom); if there are more than one
video intercom/intercom in parallel (max.3) in the apartment they can be
connected to each other in serial (in-out) terminating the impedance
only on the line of the last apparatus. There are 3 types of video
distributors identifiable by the final letter of the part number:
programmable (A) type, active (Q) type and Passive (P) type.
The programmable distributor can be used to connect all internal
stations, the passive is only for myLogic, Echos and Exhito
(EX3262) lines while the active is dedicated to the Zhero line and the
EX3252 model of the Exhito series. The intercoms can be connected
to all distributors of mixed intercom/video intercom systems while
intercom-only systems can be connected directly to the riser.

Line distributor
Allows the power, data and audio to be sent on the two
wires of the DUO system.
Line separators
They are used for separating and isolating a riser or
the equipment of one or more apartments from the
DUO condominium lines allowing the simultaneous
operation of several risers or intercommunicating
services and home automation in individual
apartments. The 2231 separator also allows a
secondary door station to be connected.
Exchanger
Allows the signal from two different lines to be
switched onto a single line. Appropriately
programmed it can:
- send the external station video signal through a
riser with a busy signal on the other entrance;
- send the door station video signal through a riser
leaving the other free.
The use of multiple exchangers allows the switching
of multiple door stations and risers.

Riser distributor
Allows the distribution of the video signals from 4 door stations on 4
risers according to the user addresses programmed in the output line
numeric intervals. For a greater number of inputs and/or outputs use
additional distributors. Any of the outputs may be used to connect a
doorkeeper exchanger.

4 or 7 exchange selector
Allows the selection of up to 4 (or 7 if so
programmed) surveillance cameras. It is
possible to view the images from the various
cameras on the video intercoms either
sequentially or individually by means of suitably
programmed buttons.
Actuator
Connected anywhere on the DUO line it allows the
activation of relays or services without having to
add additional wires to the condominium line. It
can be activated from the internal stations by
means of dedicated buttons or through sensors or
buttons connected to the IN input. The output relay
can operate as monostable, bistable or with a
programmable time.
Doorkeeper exchanger
Desk doorkeeper exchanger (with possible application to the wall) with
display , alphanumeric keypad and 7 buttons for the main functions.
Commutations: day, night and direct call. With directory, booking of
calls, communications between internal users or internal users and
door stations with possibility of inclusion. You can view images of the
video door stations applying a ST7100W monitor or a monitor CCTV
to the doorkeeper exchanger.
