OPERATION

Doorphone with single-port decoder can be used for voice calls
with entrance modules, guard door switchboard stations or special
doorphones.
The doorphone is provided with a door lock release key. When the key
is pressed, the unit emits a courtesy tone to indicate that the lock has
been released.
During programming (see the paragraph headed 'Programming'),
a riser column code, a user code and codes associated with two
additional keys (optional) must be assigned. All of these codes are
resident on an EEPROM memory which guarantees that they are
retained even with power off.
During operation, the doorphone with single-port decoder analyzes the
code emitted by the calling device and, if it corresponds to the code for
which it has been programmed, the doorphone will accept the call.
The conversation can last up to ten minutes if no calls are made to
another user. The video signal (where applicable) will remain for the
entire duration of the conversation.
After the 10-minute time-out period, or if the call is interrupted by a
call to another user, the doorphone with single-port decoder sends a
courtesy tone to the connected station to inform the user that the call
has been interrupted.
The doorphone with single-port decoder is provided with three special
keys which can be used to send command signals:
• Door Lock Release.
• Call Switchboard.
• Call Special Doorphone.
The doorphone emits a courtesy tone each time one of these signals is
sent. Only one door lock release signal is needed, even if the system
includes several outdoor stations, each with an electric lock: actuating
the door lock release key will open the electric lock only at the outdoor
station from which the call was made.
