Appendix C: Using a Model 620x in a
Model 26-based System
Overview
With the advent of the IP FSA system, Zetron has stopped manufacturing the Model 6
station transponder unit. This appendix is intended as sort of a FAQ section for installers
faced with utilizing a Model 6203 or Model 6204 station transponder in an existing Model
26-based system either as replacement for a failed Model 6 or as an expansion for the
system as a whole.
The good news is that the Model 6203 and 6204 units share a great deal with the original
Model 6 primary and secondary station transponder units. Utilizing them in this
application is mainly a matter of ignoring the IP interface and making use of controls and
settings that may not normally be used in an IP FSA system.
