When the switchboard station is in “DAY” service and receives a call
from a main entrance panel, the ringer will be activated and zone C of
the display will show “<nnn>”, where “nnn” is a number from “000” to
“999” identifying the entrance panel concerned.
When the handset is picked up, the switchboard station automatically
connects the voice line with the main entrance panel. The switchboard
attendant speaks to the caller and, upon learning the name of the
desired resident, enters the corresponding code on the keypad and
presses the call button (8). If the called apartment station answers, the
attendant can put the entrance panel in direct communication with the
apartment station by pressing key (20).
Example:
a) A call is received from a main entrance panel:
The door can be opened by means of door lock release key (25)
in the following cases:
•
Directly, for as long as the entrance panel number < nnn >
remains on the display.
•
Indirectly, by entering the number of the entrance panel at any
time and pressing the door lock release key (25).
b) The switchboard attendant picks up the handset.
c) The switchboard station connects the voice line with the entrance
panel < nnn > (LED 21 on, LEDs 19 and 23 off).
d) The attendant asks the visitor to indicate the desired resident.
e) The attendant enters the code corresponding to the desired
apartment station (e.g., 1578) and then presses the call button (8)
one or more times.
f) The switchboard station automatically connects the voice line with
the apartment station (LED 23 on, LEDs 19 and 21 off), and when
the resident at the apartment station picks up the doorphone
handset to answer the call, LED 29 goes on.
g) Finally, the switchboard attendant presses key (20) to connect the
entrance panel with the apartment station (LEDs 21 and 23 off,
LED 19 on).
h) LED 29 will go on to indicate that a call is in progress between the
entrance panel and the apartment station. The display will show:
Notice: From this moment onwards, the switchboard attendant
can only open the entrance door by entering the number of the
entrance panel (nnn) and then pressing the door lock release key
(25) (see below).
i)
When the doorphone handset is hung up at the end of the call,
LED 29 goes off and the information “nnn
→
1578” is cleared from
the display after approximately 4 seconds.
When the switchboard station is engaged in a call with an apartment
station and receives another call from an entrance panel, the attendant
can switch the voice line to the entrance panel by pressing key (22).
The attendant can then switch the voice line back to the apartment
station (if it has not hung up in the meantime) by pressing key (24).
When the switchboard station is engaged in a call with an entrance
panel and receives a call from an apartment station, the number of
the apartment station will appear on the display. In this case, the
switchboard attendant can call the apartment station by pressing the
Call from Queue key (6). After talking to the apartment station, the
attendant can return to the entrance panel call by pressing key (22).
When an apartment station is engaged in a call with an entrance panel,
the switchboard attendant can press key (22) to talk to the visitor at the
entrance panel without being heard by the apartment station, or press
key (24) to talk to the resident at the apartment station without being
heard at the entrance panel.
To restore direct communication between the entrance panel and the
apartment station, the switchboard attendant can then press key (20).
DOOR LOCK RELEASE FUNCTIONS
The digital guard door 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”.
Main entrance door lock release
Main entrance door locks can be released under the following two
conditions:
Following a call from a main entrance panel
For as long as the entrance panel number < nnn > remains on the
display, the door can opened simply by pressing the main entrance
door lock release key (25).
At any other time
To open door, enter the main entrance panel number (001 - 999) and
press the main entrance door lock release key (25). In the specifi c case
of a main entrance panel identifi ed by the number <000>, simply ensure
that display zone “D” is empty (e.g., clearing the display by means of key
(9)) and press the main entrance door lock release key (25).
Secondary entrance door lock release
NOTE:
The switchboard station will perform the operations described
below only if the secondary door lock release key “D” (11) was
activated during switchboard station confi guration.
The procedure used by the switchboard attendant will depend on the
system’s installation TYPE as follows (see “System and Installation
Requirements”).
TYPE 1 - Enter the secondary entrance panel number (1 to 9) and
press key “D” (11).
TYPE 2 - Enter the secondary entrance panel number (1 to 99) and
press key “D” (11).
TYPE 3 - Enter the secondary entrance panel number (1 to 999) and
press key “D” (11).
Door lock release in special systems
Special systems are those having the following characteristics:
•
No more than two main entrance panels, all of which are conventional
panels adapted by installing a digitizer Ref. 826/16.
•
One digital guard door switchboard station.
•
No secondary entrance panels.
This type of system, which is often used in renovating older installations,
is covered by diagram SC 101-0347. In this case, main entrance door
locks CANNOT and MUST NOT be released as described above.
Door locks can be released ONLY by using keys A, B, C programmed
to control two or three special services decoder units (Ref. 826/54)
associated with the corresponding entrance doors.
The reason for this is as follows:
If the main entrances are equipped with call modules, they can be
identifi ed by means of different numbers (e.g., Entrance 1, 2 or 3)
stored in memory during programming step 3. In this way, switchboard
station key A, B or C can be programmed at step 7, 8 or 9 with the
