Control Station Duetto

1.7/1217
General
If the DUETTO device is configured as a control desk, the station can carry out the following control
desk functions in addition to the standard Intercom functions:
Call requests
: With pressing a call button on a station, a call can be requested from the DUETTO
control desk. Active call requests are stored at the DUETTO control desk and have to be acknowl-
edged manually in order to initiate a call to the respective station. It is not possible to cancel active
call requests and therefore to decline a not accepted call. Not acknowledged call requests are indi-
cated on the display of the DUETTO device and an acoustic signal (“buzzer”) sounds.
Input messages
: Activated inputs (e.g. Gx-8E8A, Gx-16E, station inputs) are stored at the DUETTO
control desk and have to be acknowledged manually. Not acknowledged call requests are indicated
on the display of the DUETTO device and an acoustic signal (“buzzer”) sounds. Depending on the
configuration and cabling of the inputs, 5 different switch steps can be indicated:
Idle mode
Active 1
(equivalent to a “normal call”)
Active 2
(equivalent to an “emergency call”)
Short circuit
Line fault
For incoming call requests and input messages, the following call types are available:
Control desk “call types“
Normal call
:
Call request with standard priority.
Emergency call
:
Call request with high priority.
Line
fault

lance system).
