Interface for Door Intercom System

There are different ways of connecting door intercom systems:
• Using an options card OI-2DOOR (only systems 20x5)
• Using an options card ODAB (only systems A150/300)
• Using an ordinary analogue terminal port
In a connection using an options card, the equipment or installation is controlled
via relays and a control input on the options card.
In a connection using an analogue terminal port the TFE must be capable of send-
ing and receiving DTMF signals as the control is effected acoustically via a speech
path.
A bell key is backed by an internal destination. The door intercom system can be
addressed via an internal number.
A loudspeaker system can also be operated via the interface for door intercom sys-
tems.

Interface for General Bell

Calls can also be routed to the general bell. Bells or lamps connected to the general
bell interface signal calls which can be answered by anyone from any user's phone.
Coded ringing can be used to assign different ringing patterns to different destina-
tion persons or groups and, in this way, create a simple type of paging system.
Tip:
One analogue terminal interface per system can be reconfigured in such
a way that it is also used for connecting a general bell. This eliminates the
need for an external ringing voltage source.
