Diesel Fire Pump Controllers

Please use the filters located on the left to narrow your search. Joslyn Clark offers a variety of fire pump controllers in varying voltages and configurations, powered by either diesel or electricity. These diesel and electric fire pump controller products set the industry standard for performance, consistency, and reliability. Electric Fire Pump ControlElectric fire pump controllerler Joslyn Clark's electric fire pump controller products are compact but still boast more horsepower per cubic inch than any other electric fire pump controller on the market. Our flagship electric fire pump controller line is the new ProGuard series. All Joslyn Clark electric fire pump controller models are available with an optional Automatic Transfer Switch. This option is housed in an isolated compartment and complies with the National Fire Protection Association and NFPA-20 standards. It comes factory-assembled, wired, tested, and shipped as a single unit. The Automatic Transfer Switch ensures that if primary power fails, the electric fire pump controller begins operating from emergency power (without user intervention). Upon restoration of normal power, the electric fire pump controller will resume operation from primary power. LED power indicators as well as an audible alarm are included as standard features on an Automatic Transfer Switch equipped electric fire pump controllers. N.O. And N.C. contacts are provided for remote signal of the switch position. Diesel Pump Fire Pump Controllers Joslyn Clark's B series is a line of diesel fire pump controller products. This is a type of electric fire pump controller designed for diesel engine driven fire pump service. The B series diesel fire pump controller is designed to start the diesel engine automatically from water pressure control or non-automatically from manual electric control. Furthermore, this type of electric fire pump controller functions to maintain the charge on engine starting batteries, monitors engine and system condition, and initiates a weekly program test of the system. Jockey Pump Controllers Joslyn Clark also offers a Jockey Pump electric fire pump controller as an accessory to a main or limited service pump. This very small electric pump controller maintains stand-by pressure in the fire protection system to prevent wear on the main pump. Joslyn Clark type JM Jockey Pump controllers are available with automatic type starting as standard. This type of electric pump controller is available in a wall-mounting enclosure that meets type 2, 12, and 3R requirements with an optional 4X rating.

Wires for Starting and Stopping the engine as well as monitoring temperature, oil pressure and speed, are used between the engine and controller. Battery charging and powering the controller are also used in this connection. Usually 9 to 11 wires are run between engine and controller.
  • 20. Pressure Transducer and Test Solenoid Valve A Pressure Transducer converts the sprinkler system pressure to a variable voltage output. The controller reacts to the changing voltage and causes the engine to start or allows the engine to be stopped if pressure is satisfied The Test Solenoid Valve dumps pressure from the Transducer for a simulated drop in pressure test.

  • 23. Diesel Fire Pump Controls Testing the Fire Pump Controller
  • 24. Testing the Fire Pump Controller When Testing the fire pump Controller, the controller mounted buttons and devices need to be tested as well as the devices on the engine and in the pump room. Manual Operation, Automatic Operation, Alarms, Shutdowns, all should be checked out to make sure they are working correctly.
  • 25. Testing Manual Operation  Place the Selector Switch in the Manual Position.  Monitor the Water Solenoid Valve on the engine cooling loop. It should energize when the selector is moved to the Manual Position.  Pushing the Controller Mounted Start #1 Button Causes the Engine to start.
  • 26. Testing Continued  When the engine starts, it should run until you switch the Selector to the OFF position. The Permissive Stop does not operate in Manual Mode.  Moving the Selector to the Auto Position tests the Automatic portion of the controller.
  • 27. Testing Automatic Operation  If pressure at the sensing line is above the start setpoint of the controller, the unit will not start.  Open the pressure line and drop the pressure at the transducer. The engine should start and run.  Once the engine beings acceleration, watch the front of the controller for a Red LED at Engine Running.
  • 28. Testing Automatic Continued  When the engine reaches about 15% of its rated speed, a device called an Engine Speed Switch, sends a signal back to the controller telling it that engine is running and stop trying to start. If the engine accelerates over 120% rated speed, another contact closes and causes the engine to stop. A test button allows testing of the overspeed device without damage to the engine.
  • 29. Testing Automatic Continued  If the line pressure has exceeded the upper set point of the pressure controller, pressing the Permissive Stop Push Button will cause the Engine to Stop. If pressure is still below upper set point, then the selector must be moved to the OFF position.
  • 30. Testing Continued  Next, Start the Engine in the Automatic Mode.  Go to the Engine Temperature Switch and short the terminals with a piece of wire. The Bell on the Controller should ring and the Over-Temperature light should come on. The engine should not stop.  Using the same wire, short between terminals 11 and 4 on the terminal strip. Wait for 3 to 6 seconds for the Timer to time out, then observe Low Oil Pressure light on the Controller and ringing bell. Again, the Engine should not stop
  • 31. Testing Continued  Next, Testing the Crank Cycle Timer on the Controller and the engine starting capabilities.  Disable the Fuel Solenoid on the engine so the engine will not start  Allow the controller to attempt and Automatic Start.  The Engine should attempt a 15 second start.
  • 32. Testing Continued  Next, the engine should rest for 15 seconds.  Then, the controller should switch to the other battery set and attempt another 15 sec. start.  Then another 15 sec rest period.  The controller should switch back to the first battery set and another 15 sec. start attemp.
  • 33. Testing Continued  After 6 attempts to start, 3 on each battery set, the controller issues a Failed to Start Alarm. The Bell rings and the Failed to Start LED lights up.  The selector switch must be moved to the OFF position to clear the controller and reset it.
  • 34. Testing Controllers Permissive Stop Button Start #1 Pushbutton Start #2 Pushbutton Auto – Off – Manual Selector Switch BACK
  • 35. Testing – Engine Sensors Temperature Switch Short two terminals together to simulate Over-Temperature Back
  • 36. Testing – Engine Sensors Back Disabling the Fuel Solenoid on the Clarke Engine will allow testing of the Crank Cycle Timer and Alarm Function. Engine Should attempt 6 Starts, each 15 sec. with 15 second rests between starts. Alarm at failure of last start. Fuel Solenoid Remove Blue Wire to Test Crank Cycle.
