SYSTEM OPERATION
CALL AND BUSY STATE MANAGEMENT
The 2Voice system allows several conversations at the same time on different columns, in addition to a
further conversation between main calling station and an apartment station belonging to any column not
engaged by the conversation.
The system works as follows when a call is made:
• A call from a main call station switches all the other main calling stations and the entire column of the
called apartment station to busy for a call pick-up time (max. 60 s). During the call pick-up time, the system
(main calling stations and secondary stations on the concerned column) is switched to busy. When the
user picks up and establishes a conversation, the busy state is prolonged for the guaranteed conversation
time: this time confi gurable during installation from 1 to 70 s. After the guaranteed conversation time,
another call can interrupt the conversation. The maximum conversation time is 10 minutes.
The system returns to standby mode at the end of the conversation or after the timeout.
• A call from a secondary calling station will cause the same effects, but will exclusively involve the
concerned column, including the secondary station, if applicable, but not the other calling stations (either
main or secondary).
The system returns to standby mode at the end of the conversation or after the timeout.
• Auto-on from an apartment station to a calling station will switch all the main secondary calling stations
and the entire column of the door unit to busy for the call pick up time (max. 60 s.) – but not the secondary
calling stations of the other columns. If the apartment station user picks up the call (either by picking up
the handset or – on hands-free video door phones – by pressing the specifi c button), the busy state can
be extended for a time equal to the guaranteed conversation time or not (confi gurable during installation
from 1 to 70s). During the busy time generated by auto-on, normal door phone calls may interrupt auto-
on or not according to the call station programmed setting (interruption parameter). The maximum
conversation time is 10 minutes. The other apartment stations in the system cannot operate the auto-on
function for the busy time.
The system returns to standby mode at the end of the conversation or after the timeout.
• An intercom call will switch all the apartment stations in the column and possible secondary calling
station to busy for the pick up calling time (max. 60s). When the called user picks up, the busy state
may be extended or not for the time equal to the guaranteed conversation time (confi gurable during
installation from 1 to 70s). During the busy time generated by and intercom call, normal door phone
calls may interrupt the intercom call or not according to the call station programmed setting (interruption
parameter). The maximum conversation time is 10 minutes.
The system returns to standby mode at the end of the conversation or after the timeout.
• A fl oor call will not effect the system busy state.
CALLING STATION FUNCTIONS
§
For specifi c features of each call station, see its instruction manual.
CALL FORWARDING
The following cases may occur when a call is made (i.e. when a calling button is pressed on a door unit)
according to the state of the calling station state and of the called column:
• Free system: the station outputs a call forwarding tone (1 beep).
• Busy system: the station outputs a warning tone (3 beeps in sequence) and the yellow LED on the front
will blink until busy mode ends. Press the calling button or make the call again according to the station
type at the end of busy mode.
DOOR ELECTRIC LOCK MANAGEMENT
The calling stations have two terminals for managing the capacitance discharge and hold of the door electric
lock (SE-, SE+). Consequently, no separate power source is needed to operate the electric lock.
The electric lock is operated in the following cases:
• Whenever the hall button is pressed (terminals PA, CT).
• When a door open command is received from an apartment station according to the confi guration ("free"
or "privacy"):
– "Privacy": the electric lock may only be activated by pressing the door opening button on the calling
