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 3-10 show various configurations for
single-zone paging. See Figure 3-11 and Figure 3-12 for 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
