Appendix C: Using a Model 620x in a Model 26-based System

Figure 56: Model 6 Secondary Station Unit versus a Model 6204
The manual that you will receive with you new Model 6203 or Model 6204 is this manual,
part number 025-9581. It will aid you considerably to locate a copy the original Model 6
product manual, part number 025-9157, before starting the installation of the new unit.
Since the most likely scenario for your having to use a Model 6203 or Model 6204 in this
manner involves there being an established Model 26-based fire station alerting system up
and running, a great deal of your work will involve installing and configuring the new unit
in the same way the existing Model 6 units are set up and configured.
Unit Number and Serial Programming
When used in a fire station alerting system that is controlled by a Model 26 Fire Station
Dispatcher unit, the IP interface that is built into the Model 6203 or Model 6204 is not
connected to anything. It is, therefore, not necessary to assign any IP address to that
interface.
Unit Number Assignment
The Model 26 keeps track of and controls the station transponders by their unit numbers.
All primary station transponder units fall in the range from 1 to 511. At stations that have
secondary station transponder units, the unit numbers for the secondary units are
determined by adding 512 to the number of the primary unit. For example:
if the primary unit number = 5
the secondary unit number = 5 + 512 = 517
This arrangement allows the Model 26 to keep track of each individual transponder and
recognize which units have been paired together.
