Using a Model 26 Fire Station
Dispatcher for System Backup
Overview
Prior to the introduction of the IP-based Fire Station Alerting system, Zetron offered a
system based on FFSK signaling. This system used a unit called the Model 26 Fire Station
Dispatcher in the communications center which alerted a unit called the Model 6 in the fire
stations.
The motherboard and much of the firmware that makes up the Model 6203 and Model
6304 units comes from the Model 6. (For the remainder of this chapter, any mention of the
Model 6203 should be understood to refer to the Model 6204 as well, unless specifically
stated otherwise.) While the Model 6203 units are intended for building IP-based systems,
Note In order for the system backup arrangement described in this
chapter to work correctly, the Station Transponder units in the
system (whether they are newly manufactured Model 6203 or 6204
units or updated Model 6 units) must be using firmware
601-1409
revision 1.11 or later (check the label on the EPROM in socket U9 ).
If you find that some of your units need to be updated to the
correct firmware revision, please contact Zetron at 425-820-6363,
ask for Technical Support, and arrange to receive the required
firmware upgrade for the units that require it. Please have a list of
the unit serial numbers ready when you call as they will be required
to issue updates.
Note Whenever the system is operating in the backup mode (using the
Model 26 to alert stations), the Station Transponder Talkback
function is disabled and the handset on the Station Transponder
unit cannot be used to speak to the dispatch operator.
