The MasterTech IV™ features color display screens with large font sizes and “at –a-glance” off and on color blocks. The housing design has a stylish appearance with backlit buttons.

The function and capabilities of microprocessor based multiplex electrical systems continue to expand and evolve, offering significant advantages over traditional rocker switch and relay based systems. The fundamental advantages, 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 are all integrated into version IV. There are additional features that take the MasterTech IV™ above and beyond when it comes to state-of-the-art ambulance 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.

A clock timer function provides easy selection of pre-programmed time intervals with “seconds” elapsed sweep display and digital elapsed time reading.
