called door phone handset is unhooked, contact is established and
conversation may take place. To operate the electric lock it is suffi cient
to press the proper push button.

FUNCTION
BASIC DIAGRAMS FOR 1+1 WIRE ELECTRONIC DOOR PHONE SYSTEMS
Connection of door phones to 1 outdoor station with secrecy of conversation
URMET DOMUS 1+1 wire system allows to obtain the service of a
standard outdoor set installation with conversation, call, electric lock
opening, with only 2 wires in the rising column: 1 common + 1 single
for each door phone. The outdoor set is fed, with two wires only, by a
12Vac voltage transformer.
To assure call secrecy on all the door phones of the system, specifi c
secrecy circuits (one for each button) are fi tted inside the push button
panel. In this way, all the door phones are normally disabled for
conversation (no conversation is heard when the hand-set is lifted);
only the door phone called from the outside can start the conversation
with the caller, certain that no other user can barge in and intercept the
call.
The door phone called remains enabled for conversation until a
subsequent call to another appliance is made from the push button
panel.
Release of the electric lock is also enabled by the secrecy circuit
which means that a user cannot open the lock unless he/she has been
called.

FUNCTION
BASIC DIAGRAMS FOR COAX ELECTRONIC VIDEO DOOR PHONE SYSTEMS
Connection of video door phones to 1 video outdoor station
This system allows connection between the video outdoor station
and the various monitors situated in the apartments. When the visitor
presses a button on the push button panel, the bitonal electronic call
is sent to the corresponding monitor loudspeaker and, after about 8
seconds, the image appears on the screen.
At this point the user sees the visitor and can answer, if he wishes,
unhooking the handset.
At the end of the conversation, the electric lock can be operated by
pressing the key ( ).
Vision of the image lasts about 60 seconds, after which the intervention
of the built-in timer in the power supply causes it to go off. If a second
monitor is called before the end of the 60 seconds, the fi rst monitor will
automatically go off and the latter comes on. This feature guarantees
secrecy of vision.

BASIC SYSTEM DIAGRAMS

BASIC SYSTEM DIAGRAMS
FUNCTION
The 5-wire video door phone system implements conversation privacy,
call and door opener functions in normal door phone systems with only
5 wires in the riser column: 4 common + 1 single for each device.
The door unit is powered with only two wires and a transformer at
12V~.
The most interesting application of a 5-wire system is in old building
where a door phone system is already fi tted. The existing service can
be transformed into a video door phone system without adding wires
to the column or in the apartments.
Specifi c conversation privacy circuits must be fi tted in the panel for
ensuring conversation privacy for all video door phones in the system
(one for each button).
All video door phones are normally deactivated (no sound is heard
when the handset is picked up); only the video door phone called from
the door can start the conversation. No other users can cut into the
call.
The voice circuit of the called video door phone remains activate until
the following call is made from the panel to another device.
The door opening function is connected to conversation privacy; this
means that a user must be called to be able to open the electrical
lock.
