The FT Series Fire Pump Controllers are designed to provide automatic transfer from normal to alternate power when the normal source of power drops below 85%, or is lost in any or all phases of the normal power supply. 

Incorporated into the FT Series controllers is the ATC-300 controller, whose primary function is to accurately monitor two power sources and provide the necessary intelligence to operate a transfer switch in an appropriate and timely manner. The ATS-ATC-300 uses proven microprocessor-based technology that provides a high reliability and accuracy for all voltage sensing and timing functions. All functions are user programmable via keypad inputs. 

As well, all transfer switch controllers are available as a combined controller / transfer switch or separate stand alone unit. 

The Automatic Transfer Switch and fire pump controller are each mounted in seperate enclosures to form one unit and interwired.
