Front Panel Features and Operation
a
Speaker — This integrated speaker provides mono output at the
IPI panel.
b
Mic On LED — This LED lights under two circumstances:
• When a configured Push to Talk button is pressed.
• To indicate that someone at the help desk console is listening
and that the intercom is in monitoring mode. Monitoring
mode permits hands-free operation: the user does not have to
press the Push to Talk button to speak into the intercom. It
also lets help desk staff monitor what is happening to
determine whether to send security personnel to that room.
c
Microphone — Speak into the microphone, which is behind this
opening.
d
Level switch — This three-position switch lets
you change the speaker’s loudness level (IPI 100
series, only).
