number of the main entrance. It will thus be possible to release the
main entrance door locks individually simply by pressing key A, B or C.
If, conversely, the entrances are equipped with conventional entrance
panels and digitizers, this is not possible because the entrance panel
number cannot be programmed in the digitizer, and the switchboard
station would release the two or three door locks at the same time,
as they are all connected in parallel. Consequently, two or three
special services decoder units must be programmed for key A, B or
C functions. The decoders must be confi gured with relays operating
in monostable, direct drive mode, i.e., jumpers PT1 e PT2 must be
installed. Jumper PT3 has no effect in this confi guration, and can be
positioned as desired.
SPECIAL SERVICE CODES
Actuator control
The digital switchboard station can manage electric actuators using
special services decoder units Ref. 826/54.
For example, stair lights can be turned on or off by entering a special
code assigned to the stair light actuator. Special codes must be
preceded by pressing number key ‘0’ and followed by pressing the call
button (8).
Thus, to activate the service associated with code 1356, press number
keys 0, 1, 3, 5, 6 in succession and then press the call button (8).
This procedure can be simplifi ed by programming the switchboard
station function keys A, B and C. A maximum of three frequently used
special services can be activated in this way. Each time a function key
is pressed, the switchboard station will automatically dial and transmit
the code assigned to the key. For details of function key programming,
see the section covering switchboard station confi guration.
SENSOR MONITORING
The switchboard station can be connected to a special services
decoder unit (Ref. 826/54) in order to display the status of a sensor
(see the appropriate section of this manual for further details).
Say, for example, that the switchboard station is operating in NIGHT
service and the queue memory contains two calls, the fi rst of which
was from the apartment station identifi ed by the code 345. The display
will show:
The switchboard attendant can monitor garage light status by entering
the code assigned to the special services decoder unit used for this
purpose (e.g., one connected to a photodetector) and put through the
call.
After this operation, the switchboard display will indicate one of the
following conditions:
Here, “ON” means that the lights are on, while “OFF” indicates that
they are off.
The “ON” and “OFF” messages will be displayed for approximately 5
seconds, and will then be cleared.
Combined actuator control and feedback monitoring
The two capabilities described above can be combined in order to:
•
Control an actuator, and
•
Receive feedback confi rming that the desired actuator status has
been achieved.
In this way, for example, the switchboard attendant can turn on the
stair lights and check that they are on by means of the switchboard
station display, where the word “ON” will appear for 5 seconds.
For further details, see the instruction manual covering the special
services decoder unit (Ref. 826154) and the recommended installation
diagrams.
SPECIAL FUNCTIONS - CLOCK/DATE DISPLAY
Clock display
The current time is shown on the display only when the switchboard
station is operating in NIGHT service.
Time format:
hh = Hour (00 to 23)
mm = Minutes (00 to 59)
SS = Seconds (00 to 59)
Date display
When the switchboard station is operating in NIGHT service (and only
under these conditions), the current date can be viewed by pressing
the clock key 2). The date will be shown in mm/dd/yy format for
approximately 3 seconds, after which the current time will return to the
display.
Date format:
mm = Month
(01 to 12)
gg = Day (01 to 31)
yy = Year (00 to 99)
Date/time adjustment
The date and time setting procedure is activated by pressing key (2)
twice in succession with the switchboard station operating in either
DAY or NIGHT service. If the switchboard exchange is in NIGHT
mode, the display will show:
