Firetrol® FTA1500 Primary Resistance Fire Pump Controllers use resistors in the line to reduce line voltage when starting the pump motor. The controller monitors, displays and records fire pump system information. The circuit to the motor is not opened during the transition from start to run. While starting, the motor will draw 50% of full load starting current and supply 25% of rated torque. This method of starting minimizes line disturbances and voltage drop when starting.
Firetrol fire pump controllers are listed by Underwriters’ Laboratories, Inc., in accordance with UL218, Standard for Fire Pump Controllers, CSA, Standard for Industrial Control Equipment, and approved by Factory Mutual. They are built to meet or exceed the requirements of the approving authorities as well as NEMA and the latest editions of NFPA 20, Installation of Centrifugal Fire Pumps, and NFPA 70, National Electrical Code.
