About Master Control Systems

Est. 1965

Control Systems Built to Last

Established in 1965 by William L. Stelter, Master Control Systems has been Leading the Way in Fire Safety for over 40 years. We manufacture Fire Pump Controllers for fire sprinkler systems entirely within the US.

Because our Controllers are designed with innovative features that benefit the user and are engineered for long term reliability, we call our product line “The Intelligent Choice”. Our controllers, including our invention – the Variable Speed Fire Pump Controller, meet and exceed the requirements of NFPA 20, UL, and FM.

In addition to the world’s best line of Fire Pump Controllers and Jockey Pumps, Master Controls also manufactures high reliability stand-by and float service Battery Chargers as well as an extensive line of Industrial Control Panels including pumping panels for duplex, triplex and variable speed applications.

Master Control Systems remains a family-owned and operated business.
