GENERIC INFORMATION
CONFIGURATION
The system capacity is de
fi
ned by:
1 trunk line.
1 extension line.
2 door phone lines 4+n.
TYPES OF DEVICES
The telephone interface can operate either with Urmet Ref.1332 dedicated combiphones and Director2
telephones (combiphone operating mode), or with keypad BCA telephones (with DTMF) or equivalent
terminals (fax, answering machine, etc.) with BCA operating mode.
Urmet combiphones and Director2 telephones make door phone functions easier, because they are provided
with dedicated buttons; for example, it is possible to open the door simply by pressing a button. Up to 5
telephones max. can be connected in series in a system with in/out sockets (refer to enclosed diagrams).
TYPES OF SYSTEM
The Ref. 1332/40 telephone interface can be used in the following Urmet door phone systems:
Door phone systems with electronic call system (switch set on
1A
).
Door phone systems with traditional call system (door phones Mod. 1130, the interface switch set on
1
).
It cannot be connected in the following systems:
Door phone systems with conversation privacy function.
Door phone systems with concierge switchboard Mod. 604.
The two calling modes are selected by means of a switch present on the interface. By default, the telephone
interface is set for the electronic call system (position
1A
). Actually, with the interface it is possible to replace
the door phone with a telephone, in order to use the same devices to perform both the telephone and door
phone functions.
POWER SUPPLY
The telephone interface must be powered by a voltage of 12Vac, for example by a Ref. 9000/230 transformer
connected to the mains by a 2-pole circuit breaker. The mains presence is signalled by the POWER led
present on the interface, that turns on. In case of mains fail, the interface directly transfers the telephone
line to the devices, allowing, in any case, the telephone service, while the door phone service is not active
until the mains returns.

OPERATING MODES
The telephone interface may work in two operating modes, that can be selected by a programming
procedure performed with the telephone (paragraph 3.9):
Mode A
By picking the handset up, the user is immediately connected to the telephone line (no number needs to be
dialled to access the telephone line).
Mode B
When the handset is picked up, a dial tone is heard: the telephone is not connected to the telephone line or
to the door phone line. So the user can access the telephone or door phone line by entering codes.
By default, the interface is preset in mode
A
.
