SUM OUTPUTS
Each intercom line can be monitored via the
audio output of each interface module. This the
factory setting.
If required, one interface module can monitor
both intercom lines: the intercom audio signals of
both intercom lines appear on the audio output
connector of that interface module. To achieve
this, certain internal connections have to be
made :
Connection scheme A
Function:
Output of interface 1 monitors intercom lines 1+2
Actions:
Connect the right tag of interface 2 with the
middle tag of interface 1. Connect the left tag of
interface 2 to the left tag of interface 1.
