Advanced Visual Solutions AV102SS Installation And Operating Instructions Manual page 20

The Advanced Visual Solutions AV102 series of intercoms use this unit as both a power
supply source and an audio interface. These intercoms have their push-buttons isolated
from the cables by means of an internal opto-isolator device.
It is most important to maintain the correct polarity of the cables between the AV102 and
the AVPSU4 units.
The AV102 is factory wired to be a normally closed device when it is powered-up and the
push-button is not pressed.
The LED on the AVPSU4 illuminates when the call input terminals are open-circuit. This
function may be used to check that the call button is wired and functioning correctly.
