and the replacing the handset.
INTERCEPT mode
Press
button on the switchboard,
the yellow plastic insert illuminates
(no. 5 fig. 1). In mode INTERCEPT all
calls made from the entry panel are
routed to the switchboard.
Calls from entry panels are signalled
with an acoustic signal, the tenant's
code is shown on display 1, and the
monitor
is
turned
on
VPDM/100).
To attend the call it is sufficient to lift
the switchboard handset.
The porter, whilst in communication
to the entry panel, can call a tenant

the word ENGAGED), then replacing
the handset.
The conversation time between the
entry panel and tenants can be pre-
set from 30 ÷ 90 s.
When the tenant has replaced the
handset on the cradle or after the
preset time has elapsed the switch-
board returns automatically to mode
INTERCEPT and the word ENGAGED
on entry panel is turned off.
A call made from the entry panel,
whilst the porter is engaged in a con-
versation with a tenant, activates the
monitor and the code entered is
shown on dispaly 1.
The porter can attend the entry panel
call by simply depressing once the
cadle switch actuator (no. 3 fig. 1).
Calls between
switchboard and tenants
To call a tenant from the switchboard,
lift the handset, enter the code and
press
button.

To attend a communications request
the porter should press
button. In
2
multiblock installations, it may hap-
pen that a call is addressed to an
engaged block.
In this instance the indicator ENGA-
GED on display 1 illuminates and the
code remains in memory.
If the system includes a PRIVACY func-
tion, this is indicated in display 1 fol-
lowing a call to any receiver for which
the option has been programmed.
Similarly, if the system has the OFF
LINE function, the relative indication
will appear in display 1 when the
receiver is not in working order, or if
the relative handset is off the hook
(systems
with
VCD/104
VMF/100LA).

To enable the tenants to recognized
from where the calls is made the swit-
chboard tone is different of entry
panel one.
When the handset is replaced on
cradle, the code on switchboard
dispaly is cancelled.
While the conversation is in progress,
the ENGAGED signal is sent out to
the entry panels.
If several communication requests
are received from the monitors the
switchboard, can store them in the
memory (max. 20 calls) and the num-
bers of the calls awaiting to be dealt
with are shown on display 2.
When the asterisk is shown, the calls
will be returned in the entered
sequence.
The porter, by pressing
can scroll the codes in memory and
at his own discretion can by-pass the
automatic sequence and give priority
to any stored call.
The porter can also cancel stored
(mod.
code by pressing C2 button.
The call volume can be regulated at
the switchboard by a potentiometer
accessible through a slot in the hou-
sing bottom.
If a camera in installed in the porter's
lodge, the tenant will see the porter
when conversing to him.
Alarms (system 100)
Switchboard is provided with 2 line
for emergency or alarm indications.
When the monitor is equipped with
alarm facility and the alarm line is
activated, the monitor code is
displayed on switchboard and PANIC
or ALARM indications appear on
but-
display 1.
In addition the alarm code generates
a continuous acoustic signal different
from that following a call. The alarm
code override any other ones that
may be registered in memory. The
type of emergency is indicated in
display 1 by the caption ALARM or
PANIC.
The alarm status can be reset only
attending the call by pressing
button.
FUNCTIONS PROGRAMMING
Switchboard is provided with 8 dip-
switches for programming the func-
tions required by the video entry
systems. The dip-switches can be
reached from the switchboard bot-
tom.
To access the dip-switches remove
the steel base B as shown in figure 3
(positions 1, 2 and 3). When you have
programmed the functions, replace
the base and secure it with the fixing
device A (position 4).
Call acknowledge
Switchboard is protected against
possible code misreading.
A code before is acknowledged
should be read at least 4 consecutive
times – dip-switch 2, table 1, to posi-
tion ON – or 8 times with dip-switch 2
to position OFF.
Identification of
entry panel calling the porter
In video systems with only one entry
panel a call addressed to the porter
is identified on display 1 with word
PORTER – dip-switch 3 to position
ON – table 1.
In video systems with more entry
and
panels the one calling the porter will

be identified on display 1 by the fol-
lowed by 156 number assigned
(max. 2 digit) – dip-switch 3 to posi-
tion OFF table 1.
Multiblock call mode (dip-switch 4,
table 1, to position ON)
The code (max. 5 digit) is made up of
block code (0 ÷ 80) and receiver
code (0 ÷ 155).
Codes from 157 to 161 are for auxi-
liary services only.
Codes from 162 to 242 can be used
for special functions.
Progressive call mode (dip-switch
4, table 1, to position OFF)
The available codes are 0 ÷ 12636.
The codes reserved to auxiliary servi-
ces only are 78000 ÷ 78161, 79000 ÷
79161, 80000 ÷ 80161.
The codes from 12636 to 19682 can
be used for special functions.
Call tone duration
The duration of time for which the
1
code is transmitted to the receivers
may be varied by means of dip-swit-
ches 5 and 6, table 1.
Switchboard is supplied factory set to
1 s (dip-switches 5 and 6 both to
position ON).
Language (I, GB, D, F)
The switchboard can be program-
med by means of dip-switches 7 and
8 to following languages see table 1.
