OPERATION
Calls from an entrance panel, intercommunicating calls and door calls are
differentiated by means of different tones.
Door calls.
Calls from entrance panels do not follow the pressed pushbutton but are
generated inside the interphone. The call interval is 1 second of ringtone
and 2 seconds of pause repeated twice (default value set on panel). To an-
swer, raise the handset. If the handset is already raised during the call, re-
place and raise it again. The call answer time (30 s) and the conversation
time (2 minutes by default) are set in the panel parameters. When the con-
versation time has elapsed, the user can continue without replacing the
handset if a new call is made within 10 seconds from the same panel.
Intercommunicating call.
Lift the handset and press the intercommunicating button for the inter-
phone/monitor to be called. On the handset of the interphone called a call
tone will ring (if the call is enabled) or an engaged tone (if not enabled). On
the called interphone the ringtone starts sequentially at intervals of 1 se-
cond ringing and 4 seconds pause. The maximum duration of the call is 30
seconds (6 cycles). To answer the call, simply raise the handset; the maxi-
mum duration of the conversation is 5 minutes. When the conversation
time has elapsed, the user can continue without replacing the handset if a
new call is made within 10 seconds. Calls from the panel have priority over
intercommunicating calls.
Lock Button
The lock button of each device works in the following manner.
- Device with handset at rest lock to the last entrance panel with
which it has spoken or from which it has been called.
- Device with handset raised but not engaged in a conversation call
to switchboard if the Switchboard flag is YES. Otherwise it goes back
to the first case.
- Device with handset raised and engaged in an internal conversation
as in the first case.
- Device with handset raised and engaged in an external conversation or
called from entrance panel lock to the entrance panel being spo-
ken with or from which it has been called.
In practice a lock is always activated except when the handset is raised
and you immediately press the lock button. This can also be taken to the
standard case if the system has no porter switchboard and the Switchbo-
ard flag is set on NO.
IDENTIFICATION CODE ASSIGNMENT FOR MONITORS
To associate an identification code with interphones or monitors, refer to
the instructions enclosed with the devices. Programming of the identifica-
tion code must be performed on the Master panel.
PANEL OPERATION
Calls
The tone generated by the interphones/monitors, when a call is made from
a panel, does not follow the lenght of the pression of the pushbutton, but
is generated by the value of the “ringtone cycles” set on the panel (default
value = 2). Each ringtone cycle consist of 1 s ringtone and 2 s pause. On
start of the call, the monitor of the relative video entrance panel called swit-
ches on. At the end of the call, the answer time count starts, within which
the handset must be raised to answer the call. From the time that the han-
dset is raised, which can also occur during the call, the conversation time
count is starts (default value = 2 minutes). When the conversation time has
elapsed, the user has 10 s to press the call pushbutton in order, to proceed
with the conversation without hanging up the handset. If a call is made
from a panel outside this 10 s interval, while the handset is still raised, press
and then release the handset hook to answer the call.
"Engaged Please Wait" message
When the ENGAGED-PLEASE WAIT message appears, the panel is disa-
bled for calls, as another call from another panel is in progress. If a call pu-
shbutton is pressed while the message ENGAGED-PLEASE WAIT is on
display, the panel emits a long warning tone.
