DISPLAY The guard door switchboard station is provided with an
alphanumeric liquid crystal display (1) featuring two lines with 16
characters each.
The 32 alphanumeric characters are generally divided into four
dedicated display zones as follows:
Zone A
This zone is normally used to display the total number of calls stored
in queue memory (from [11 to [99] or [xx] to indicate that the memory
is full). In “NIGHT” service, this zone is used to display the time in
hh:mm:ss format.
Zone B
This 5-character zone is normally used to display the codes of
answered calls which have been stored in queue memory. The call
which was received fi rst is identifi ed by an asterisk “ * ”.
Zone C
Displays information regarding the device from which a call has been
received.
The following information may be shown:
•
1 to 9999, i. e., the code identifying the apartment station making the
call.
•
<nnn>, indicating a call from the main entrance panel identifi ed by
the number <nnn>
Zone D
This zone displays the codes entered by the switchboard attendant in
order to perform a particular function.
