Page 2 of 12 Limited Service Fire Pump Controller I Introduction The Hubbell Limited Service Fire Pump Controller provides automatic and manual control of small electric motor driven fire pumps and booster pumps of 30 horsepower or less. All Controller components are inside the cabinet with indicating lights and switch handles located next to the door. A pressure switch initiates automatic starting of the pump motor. The Controller monitors the power phases and voltage. The CIRCUIT BREAKER DISCONNECTING MEANS handle has a door interlock feature to prevent opening the door when the switch is closed. The Controller also has an EMERGENCY MANUAL CONTROL handle to start the fire pump manually.
