Loudspeaker paging without paging adapter
Figure 52 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 52 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
Chapter 1, ‘‘909A/B universal coupler’’ ).
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.
