Loudspeaker Paging Systems

A paging device is used to page co-workers and make announcements through loudspeakers.

Connect the loudspeaker paging system to an LS or GS trunk jack that is programmed for paging.

Figure 3-8, Figure 3-9,and Figure 3-10show various configurations for single-zone paging. See Figure 3-11and Figure 3-12for single-zone and multizone paging configurations that include background music, Magic On Hold®, (and Talk-Back in Figure 3-12).

DTMF Signaling

External paging systems that use DTMF signaling, such as PagePac 20 with ZoneMate 39 paging systems, can be connected to an LS or GS trunk jack programmed for paging operation, including bi-directional paging (Talk- back).

Zone paging systems, such as the PagePac series, require one LS or GS jack. Any zone can be used once the paging jack is activated.

A UPAM is required to connect the system to paging equipment such as the following:

■PagePac without ZoneMate

■Paging systems requiring a contact closure, impedance-matching transformer, or both
