Several doorbells can be configured
in the OpenCom 100. You can for-
ward these doorbells using the ap-
propriate code number procedure.
For example, select
153, to for-
ward calls for doorbell 3 or to switch
off the forwarding of calls for
doorbell 3.
How many doorbells are available
and with which code number proce-
dure these can be forwarded de-
pends on the entrance intercom that
is connected. Please ask your system
administrator which code number
procedure you should use.
Call duration
All door calls are automatically ter-
minated after a specific period has
expired (presetting is 60 seconds).
This ensures that forwarded door
calls do not unintentionally lead to
continuous calls (e.g. to a voicebox).
Your system administrator can con-
figure the period in the
OpenCom 100 from 30 to 300 sec-
onds and will be able to tell you the
current value.
Announcements
Announcements can only be made
to system terminals (corded and
cordless system terminals).
… making an announcement
Press the
Menu softkey briefly and
select the Announcement menu
item. Enter the telephone number
under To:.
The called subscriber hears a special
information tone followed by your
announcement. If you make an an-
nouncement to a group of system
telephones (e.g. to a hunt group
number on which calls are signalled
simultaneously), all called subscrib-
ers hear the announcement at the
same time. You hear a signal tone via
your telephone when the (an-
nouncement) connection has been
made to all called subscribers. If one
of these subscribers replies to the
announcement (by accepting the
call), the announcement call to the
other system devices is terminated.
If the called subscriber is a member
of a user group for which Intercom
protection is active, no announce-
ments are made to that subscriber’s
telephone number.
… responding to an

If you receive an announcement
yourself, you will hear a special
