Product manual

Introduction
10 025-9158L
Backwards Compatibility
Since its initial release in the early part of the 1990s, the Model 6/Model 26 system has
had a number of hardware and firmware updates take place. Some of these were due to
components going out of production and others were due to changes in the firm ware to
enhance customer satisfaction with the product performance.
System purchased before July of 1999 and never upgraded may be utilizing software
protocols that are no longer supported. These systems need to be updated to the current
standard release of firmware. In some cases, upgrades to the hardware will be necessary
in order to support the use of the new firmware.
If you are unsure of the status of your system, please contact Zetron Technical Support
for assistance in determining what it is.
The Model 26 Fire Station Dispatcher panel and the Model 6 Station Transponder units
must be using the same version of firmware in order to obtain reliable and efficient
operation for the system as a whole. As an example of this, if the Model 6 units in the
system are running version 3.20, then the Model 26 must be running version 3.21.
• The current Model 26 firmware is intended to work in Model 26 hardware that
was produced after December of 2003.
• The current Model 6 firmware is intended to work in Model 6 hardware that was
produced after February of 1996.
If you have Model 26 or Model 6 units which are older than the dates just listed, please
contact Zetron Technical Support for assistance in determining what upgrades you will
need. Please contact Zetron Technical Support at:
