CONFERENCE CALL
The conference function can connect up to four different users in one
phonic communication. Only the intercom which made the fi rst call
can call other intercom in the course of a conversation. In order to
include another intercom in the conversation, simply dial the extension
number. One of the following situations will occur:
•
The intercom door phone called is free: when the handset is lifted,
the called party will be included in the conversation in course.
•
The intercom door phone is free: if the handset is not lifted within 30
seconds, the call will not go through.
•
The intercom door phone called is engaged: there will be a busy
tone of a short duration.
FOLLOW-ME
This function allows incoming calls to be routed to another intercom.
Up to a maximum of eight other intercoms can be routed to one
intercom. Several consecutive reroutings of calls from one intercom
can be made to several different intercoms.
How to forward calls from one intercom door phone to another
•
Go to the other intercom door phone.
•
Lift the handset of the other intercom.
•
Press the dedicated “F” key and dial the number of your intercom
door phone.
•
Listen for the tone on the handset; one of the following two situations
will take place:
•
Dial tone: the operation was successful
→
hang up.
•
Busy tone: calls cannot be routed because calls to 8 other
intercoms have already been forwarded to that intercom
→
hang
up.
How to reset your intercom door phone
•
Return to your intercom.
•
Lift the handset.
•
Press the dedicated “F” key and dial your own number.
•
Hang up.
Secretary function
This function permits the user to route his own incoming calls to
another intercom (i.e. the secretary one). All his own incoming calls
are routed to the secretary intercom EXCEPT the call that arrives
from the same secretary. In this way the secretary can, if needed,
“announce” the calls; anyway it cannot “transfer” the call. The routed
set can always make outgoing calls (and then it can call again the
person “announced” by the secretary). This function can be carried
out by modifying the “follow me” as regard to the last paragraph (the
crossed one).
GENERAL CALLS (only from authorized intercom
door phone)
A general call can be made through a loudspeaker connected to a
suitable amplifi er.
The general call can take place at the same time as four other
conversations, without interfering with them. General call can only be
made from intercoms which were explicitly defi ned for making such
calls during the programming phase.
To make a general call:
•
Lift the handset.
•
Dial the special “99” number.
•
Wait for the “ding-dong” to be generated.
•
Make the announcement.
•
Redial the special “99” number.
•
Hang up.
ANSWERING A CALL FROM THE OUTDOOR
STATION
This feature is only available on Ref. 926/2 intercom door phone.
A call from the outdoor station produces a different acoustic signal
from the normal one and can be easily recognized. Lift the handset to
establish communication; the open-door key can be used to operate
the electric lock at any point.
When a user, engaged in conversation with the outdoor station,
receives a call from the inside, he visualize the call on the led without
the possibility to be interrupted (not even with the clearing the line
function).
Vice versa, when a user, engaged in conversation with another internal
user, receives a call from an outdoor station, he will see the blinking
led up to the call key is pressed and he will hear an acoustic signal that
indicates the call with more emphasis.
PROGRAMMING
All the intercom door phones are produced and tested by URMET
DOMUS. They are all programmed with the following values during the
testing phase:
•
Number: 98
•
General call function disabled: 0
•
Line clearing disabled: 0
The devices must all be programmed with two digits, e.g. from 01 to
09, from 10 to 19, from 20 to 25, or with any other number from 01 to
97.
These values can be changed at any time through the keypad by
following the procedure described below:
•
Simultaneously press the “R” and the “F” keys for two seconds. If
one or two “beeps” are heard while the keys are pressed, it means
that the two keys were not pressed simultaneously
→
repeat the
operation.
•
When the led is lit and a brief acoustic tone is heard, release the two
keys.
•
Enter the number to be assigned to the intercom.
•
The led will go off for a short interval and then go on again,
coinciding with a brief acoustic tone.
•
Set authorization (1) or disable (0) for the general call function.
•
The led will go off for a short interval and then go on again,
coinciding with a brief acoustic tone.
•
Set authorization (1) or disable (0) for the line clearing function.
•
The led goes off defi nitively, coinciding with a brief acoustic tone.
If the procedure described above is not completed within 30 seconds,
the intercom will return to normal operating conditions, without storing
the setting that were entered.
INSTALLATION
WIRES LAYING
All system intercom door phones must be interconnected in parallel
using 9 wires (or 8 if the general call installation is not provided for).
These wires have the following functions:
•
1 for the power supply voltage
+ 12
•
1 for the logical ground
ML
•
1 for the data line
D
•
4 for the 4 phonic lines
L1, L2, L3, L4
•
1 for the general call phonic line (this wire can be
omitted on installations where this feature is not required)
L5
•
1 for the phonic ground
MF
In addition, installations connected to a Call Station must be considered
4+N additional wires, which increase the number of wires to the
installation to 13+N (where N depends on the number of call keys used
– usually 1 or 2).
These 4+N wires are used as follows:
•
3 for the talk volume (F1, F2 and ground).
•
1 for the door-opener.
•
N for the call.
If the GENERAL call amplifi er is not used do not connect the wire L5.
The maximum distance between the power supply and the furthest
intercom must be less than 200 meters.
The maximum distance between two intercom door phones to ensure
a relatively low cross-talk effect is 200 meters. The cross-talk effect
increases progressively with an increase in distance.
It is therefore advisable to avoid unnecessary connections distances.
