Russound MCA-66 Installation Manual
Paging Audio IN
The MCA-66 has a paging audio input on Source 6 (right channel only) that
accepts line level audio signals via an RCA cable. The paging input interfaces
with the page output of a telephone system or other peripheral device.
When a page event is engaged, it interrupts audio outputs for all enabled
zones. System paging can be disabled permanently in each zone by software
programming or temporarily with Do Not Disturb. To utilize Source 6 for
paging input, it must be configured as a page source in the SCS-C5 software.
Note:
If Source 6 is enabled for paging events then only five other source
inputs are available.
Page Trigger IN
The page trigger input is used to trigger a page event. Paging is configurable
per zone using SCS-C5 software. A 12VDC trigger selects the audio input from
Source 6 (if configured in software as the Page Input) and sends it to any zone
that does not have page disabled or that is not in Do Not Disturb mode. Do
not use the page trigger input if there is a regular audio source connected to
Source 6.
Note:
The diagram at right shows the required wiring to the 12VDC Page
trigger in from the phone system - this will initiate the page.
