Abstract
Methods and systems for operating a fire pump controller are provided. An example method includes causing a power supply coupled to a an electric motor-driven water pump through a fire pump controller in a fire protection system to provide power to the water pump, and monitoring the performance of the power supply during the motor starting period by measuring the voltage and/or current of its output under motor load conditions. The method may also include providing visual indications, such as traces or starting signatures of motor power supply voltages and/or currents during the motor starting period for the purposes of observation and troubleshooting motor power supply and power train performance problems.
