4 Multi-Function Facility
Communications System Paging Function
In the “out of the box” configuration, the paging function will only allow Individual Zones and Fixed Zone
Groups to operate. Background Music will be broadcast on all Individual Zones. In order to program
Logical Zone Groups and edit the Individual Zones for Background Music the SP4 Telzone Programmer
software must be used. The installation and use of the SP4 Telzone Programmer software is described in
Chapter 3.
Calculate the number of Individual Zones available. The number of Individual CLASS “B”
Zones available equals the number of SP4-APS splitters times 4. The number of Individual
CLASS “A” Zones equals the number of SP4-APS splitters times 2.
(CLASS “A” = 2) or (CLASS “B” = 4)
x (# of SP4-APS splitters) = # of Individual Zones Available
Examples:
If I had 12 SP4-APS splitters, in order to calculate the number of CLASS “B” zones I would multiply the
number of splitters by 4. The result would be 48 Individual Zones available.
In order to calculate the number of CLASS “A” zones, I would multiply the number of splitters by 2. The
result would be 24 Individual Zones available.
