Loudspeaker Paging Systems
Use a loudspeaker paging system to page co-workers and make
announcements. You connect the paging system to the jack of an LS or GS
line/trunk that is programmed for paging.
Figures 3-22, 3–23, and 3–24 show various configurations for single-zone
paging. Figures 3-25 and 3-26, later in this chapter, show single-zone and
multizone paging configurations that include background music through a
Magic on Hold audio source. Bidirectional paging, also called talk-back, is
shown in Figure 3–26.
