Fire Pump Controllers

Regardless of the type of driver, most fire pumps are started automatically by a pressure signal from the pump discharge line. Each fire pump must have its own controller, including the jockey pump.

Depending upon application requirements, fire pump electric motor controllers must conform to the appropriate national regulations. Each controller must be arranged to match the starting characteristics of its motor and must include

• Manual disconnect switch

• Circuit breaker

• Starter without heaters or contactors

• Pressure switch (when NFPA is mandatory)

• Minimum-run timer to prevent motor cycling

The diesel engine controller is arranged to permit either automatic or manual start. The manual start is required to permit periodic run tests. The power source for the controller and for starting is a dual set of batteries or air containers. The controller is arranged to show the following engine conditions:

• Low lubrication oil pressure

• High water jacket temperature

• Failure to start automatically

• Shut-down due to overspeed (when NFPA 20 is mandatory)

• Battery and battery charger failure or, when equipped with one, an air system failure

The engine controller must also provide a means of relaying the following information to remote indicators:

• Engine running

• Engine switch off or manual position

• Trouble signal (activated by one or any combination of the engine or controller signals described above)

Approval of the control system for all pumps, except the jockey pump, is required in nearly all national codes.
