and secondary entrance panels, there is no way of knowing whether the
lines between secondary entrance panels and decoders are engaged.
Voice channels 1 and 2 can assume the following states:
•
Free : No call in progress. No line status information will be shown on
the display.
•
Busy : A call is in progress on the voice channel. This call cannot
be interrupted, because the programmed engaged time (which
establishes the minimum duration of a call) has not yet been
reached. The display will show the word ‘BUSY.
•
Engaged : A call is in progress on the voice channel. This call can be
interrupted, as it has lasted longer than the programmed engaged
time. The display will show the symbol .
When a voice channel is busy or engaged, the switchboard attendant is
not provided with information concerning which devices are involved in
the call. When the channel is in busy status, moreover, communication
between the two devices cannot be interrupted. In engaged status,
communication can be interrupted following a call from the switchboard
attendant.
Example: A main entrance panel calls an apartment station which is
not in the switchboard station’s assigned zone on voice channel 1:
If the call lasts longer than the programmed engaged time:
If another main entrance panel calls the switchboard station and there
are two voice lines:
The switchboard attendant can then pick up the handset and talk with
the visitor at main entrance panel 002 without interrupting the call on
voice channel 1.
DIALOG BETWEEN TWO SWITCHBOARD STATIONS
A switchboard station can call another switchboard station using the
same procedures employed for calls to apartment stations. The code
to dialed in this case is the one programmed in the called switchboard
station. Display messages differ slightly from those used when calling
an apartment station or receiving calls from a main entrance panel.
Example: Switchboard station 0001 calls switchboard station 0002.
The following information will be shown on the respective displays:

entrance panel 1 and the apartment station as described above,
and then switch the line to main entrance panel 2 by pressing key

DOOR LOCK RELEASE FUNCTIONS
The switchboard station can release locks at any door associated with
a main or secondary entrance panel at any time. This feature is called
‘PRIORITY DOOR LOCK RELEASE’.

release key .
•
At any other time: To open door, enter the main entrance panel
code (1-JJJ) and press the main entrance door lock release key .
Secondary entrance door lock release
To open a secondary entrance door, enter the secondary entrance
panel code (1-JJ) and press the secondary door lock release key .
Entrance door open LED
The switchboard station is provided with a LED to indicate main and
secondary entrance door status.
The LED can assume the following operating states:
•
LED off : Main and secondary entrance doors are closed.
•
LED on : One main or secondary entrance door is open.
•
LED flashing
: Two or more main or secondary entrance doors are
open.
The LED will go on only if doors remain open for 30 seconds or longer.
The code of the last entrance panel that signaled a ‘door open’ condition
will appear on the display as shown in the following example:
Where, ‘P-004’ designates ‘main entrance panel 004’. Secondary
entrance panels are identified by the letter ‘S’ (e.g., ‘S-00A’).
Codes for other entrance panels which have signaled a ‘door open’
condition can be viewed by pressing key . This key is active only
when the door open LED is flashing.
