Installing PagePac® Paging System
General
The PagePac paging systems use a single port to provide single or
multi-zone loudspeaker paging. A PagePac system may be used in
addition to the standard loudspeaker paging and code-calling
capabilities of the system.
Three models are available:
●
PagePac 20
● PagePac VS
●
PagePac 50/100/200.
PagePac 20
The PagePac 20 is a 20 watt amplifier that can be used alone to provide
a single zone of paging (Figure 5-4) or it can be equipped with a
Zone-Mate 9 or 39 to provide multiple paging zones (Figure 5-5). If the
PagePac 20 is used alone, a 278A adapter is required.
