INTRODUCTION
Overview
The Fire Research all-in-one pressure governor and instrument panel uses state-of-
the-art programmable, microprocessor technology. It maintains a steady pump discharge
pressure by controlling engine speed or holds a selected engine RPM. It offers complete
engine control and remote display in a single compact unit.
The governor operates in one of two modes, pressure or RPM. In pressure mode
it maintains a constant pump discharge pressure. The discharge pressure is monitored,
compared to the selected pressure setting, and the engine RPM is varied to keep the
discharge pressure at the selected setting. In RPM mode it maintains a constant engine
RPM. The pump discharge pressure is monitored and can vary, but, as a safety feature,
it will be limited to an increase of 30 PSI. If the discharge pressure increases 30 PSI
the governor automatically lowers the engine RPM to prevent a high pressure surge.
All controls and indicators are located on the front of the control module.
