Loudspeaker paging without paging adapter
Figure 330
shows the connections for the loudspeaker paging feature. These connections are used when
the loudspeaker interface equipment is not located in the equipment room. If the equipment is located in
the equipment room, the information outlet is not required. The connections shown are for one zone.
Figure 330
also shows connections from an optional customer-supplied music source to the loudspeaker
system through a paging amplifier, as well as connections to the loudspeaker system through a 909A/B
universal coupler (see
909A/B universal coupler
on page 831).
NOTE:
If the loudspeaker paging system provides a talkback microphone at the speakers, the
microphone must be FCC approved (or equivalent), or a
909A/B universal coupler is required.

SCC1, or CMC1 Media Gateway
NOTE:
On the 25-pair cable to TN763B/C/D auxiliary trunk circuit pack, SZ1 connects to GRD
on key 10. The 50 points amphenol is connected to the back of a G600 or G650 Media
Gateway.
