Paging Microphone Connection to ACU Inputs 3 to 8

The following diagram shows the connection of the SMC02 to an ACU's Mic/Line inputs 3 to 8 as a Paging
Microphone.
Note the ACU can be either the wall mount Intellevac ACU or the rack mount VAR8-ACU.
When connected to an ACU the listen-in function is activated in all VAR12 and VAR20 Routers in the
Intellevac network, in a similar fashion to when directly connected to a VAR Router. An external audio mixer
is however required to mix the AUX Outputs of all VAR12 and VAR20 Routers in the network. This mixed
audio can then be fed to the SMC02's listen-in speaker.
