The function and capabilities of microprocessor based multiplex electrical systems continues to expand and evolve, offering significant advantages over traditional rocker switch and relay based systems. The fundamental advantages all remain in the new model, such as using microprocessors in place of mechanical components, utilizing multiple processors to spread the load in place of a central "mother" board, the power modulation capability, and internal diagnostic functions. But there are many new features that make the MasterTech III the state of the art in emergency vehicle electrical control systems.

Improved control panel design includes touch button control of all emergency warning systems, warning messages, door ajar visual indicator, and access to additional menu screens.  New timer function provides easy selection of preprogrammed time intervals with "seconds" elapsed sweep display and digital elapsed time reading.

The MasterTech system provides the advantages of multiplexing using strategically located nodes and operator interface modules, delivering significant advantages over most other digital units on the market. It is programmed to control all electrical functions, system interlocks, load shedding and management with real time diagnostic monitoring and feedback that provides simple detection of open circuts or shorts. The reliability of solid state microprocessor based controls eliminates mechanical components and increases the operator's ability to monitor, display, and control vehicle activity. The system is standard in our "Prestige Package" and in "Express" can be selected as an option in all other models.
