1+1 WIRE HOUSE PHONE SYSTEM
PROGRAMMING
URMET 1+1 wire system Mod.1035A/1+1 allows to
obtain the service of a standard outdoor se
installation with conversation, call, electric loch
opening, with only 2 wires in the rising column: 1
common + 1 for each house phone. The outdoor set
is fed, with two wires only, by a 12 V a.c. voltage
transformer.
The most interesting application of the 1+1 system
is in old buildings where only the call facility exists:
without adding any further wires in the cable conduit
and in the appartments, the existing service can be
transformed into an outdoor set installation.
The 1 + 1 wire electronic house phone system
allows to obtain the secrecy of conversation.
For this purpose the special house phones Mod.
1131 and Mod. 1132, already equipped with the
proper diodes, have to be installed, while in the
push button panel a circuit for each key (mounted
onto multiple plates with 4 diodes for each 4 keys)
has to be inserted.
SECRECY OF CONVERSATION
To assure the secrecy to all the house phones,
special devices for secrecy of conversation are
inserted into the push button panel (one for each
key).
So, all the house phones will be cut off from any
converation (nothing can be heard when picking up
the handset); only the called house phone can start
a conversation with the calter, no other being able
to intercept the call. The called house phone is
qualified to talk until another call is made from the
push button panel to another house phone.
The electric lock opening depends from circuit of
secrecy of conversation (the lock cannot be operated
unless the house phone has been called).

INSTALLATION AND CONNECTION
The system works correctly with a maximum total
(forwards and backwards) line resistance of 12
Ohms.
It is therefore necessary to use:
− for distances ≤ 100 m beetween push button
panel and the farthest house phone, wires with
section 0,35 mm 2
− for distances > 100 m, wires with section > 0,35
mm 2 and such as to guarantee a line resistance
not higher than 12 Ohms
It is necessary to foresee the wires for push button
panel lamps lighting with the related adequate power
transformer (for up to 2 lamps the standard system
transformer can be used) as well as the wires for the
lock opening next to te door.
It is no possible to connect more than 2 house
phones in parallel.
EQUIPMENT
The items required for this system are the following
ones:
− House phone Mod.1131 Ref.1131/35
or
− House phone Mod.1132 Ref.1132/35
(both with diode plate inserted)
− Loudspeaking unit Ref.1035/67
− Kombi push button panel Mod.825
− Secrecy of conversation device for
Kombi push button panel Ref.1035/74
or
− Traditional push button panel Ref.725
− Secrecy of conversation device for
push button panel mod.725 Ref.1035/25
− Transformer Ref.9000/20.

Mod. 1132
Use special house phones Mod. 1131 Ref. 1131/35
and Mod. 1132 Ref. 1132/35.
The call is possible by sending to the microphone
loudspeaker an electronic call tone produced by the
loudspeaking unit.
The house phone is also equipped with an electric
lock opening (operating by pressing the proper
key).
LOUDSPEAKING UNIT Ref. 1035/67
The loudspeaking unit is placed inside double
modules.
On the front panel and the back there are two
accessible potentiometers that allow adjustment of
the external volume (EXT) and the internal volume
(INT).
