Fire pump phase reversal

Learn how to perform testing to determine if the motor is rotating properly. On an electric fire pump what are the required by code as supervisory points that are to be monitored other that Fire Pump Run and Fire Pump Power Failure? Installing sensors on equipment and wiring them to either the fire alarm system or building automation system can accomplish the monitoring.

Items to monitor include: pump running status, loss of phase power, phase reversal , and if controls have switched over to . Make sure the isolating switch is closed.

Check to make sure the reverse phase alarm pilot light is off or normal phase pilot light is on.

General: Controllers shall be furnished with digital display and data acquisition control panel for monitoring pump status, power supply status, leg voltage, leg current, phase reversal , fire pump set points, jockey pump set points, an in the case of diesel controller, all associated failure modes.

MEDIUM VOLTAGE ELECTRIC FIRE PUMP CONTROLLERS. Field inputs terminal (Dry Contact Only: Voltage Free):. This selectable display monitors voltage and amperage on all three phases and will store in nonvolatile memory . They are “ pump running,” “loss of phase power,” “ phase reversal ,” and “alternate source of power connected.

Only the “ pump running” signal can be either an alarm or supervisory . BRAND PRODUCTS CANNOT BE LIABLE FOR ANY MISAPPLICATION OR INCORRECT INSTALLATION.
