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.
