NOTE: Two CLASS “A” or four CLASS “B” zone codes are assigned to each splitter. If a zone audio

output is not used the zone code remains with that splitter.

Appendix A, in the back of this manual, is a Telephone Page Zone Control Mapping Guide which can be

used to map the zone locations and zone codes. This can assist the technician as well as the user in

identifying the locations of the paging zones.
