Tests and Testing Procedures

  • Important things to note when conducting tests:

    ENSURE THAT YOU ARE WEARING YOUR PERSONAL PROTECTIVE EQUIPMENT AND THAT ANY PERSONS IN THE VICINITY OF THE TESTS ARE ALSO WEARING THEIR RELEVANT PERSONAL PROTECTIVE EQUIPMENT.
    Note 1:
    In order to stop the diesel engine driven pump when this unit has been brought into operation via a pressure drop or the “test ” button the “ stop/reset ” button must be pressed first. The “fire alarm” light will then extinguish. Once this has been done, the fuel shut off lever can then be pulled out and the diesel engine will stop.
    Note 2:
    Should the diesel engine fail to stop and the “fire alarm” lights up again this is indicative of two basic situations: (allow the pump to restart and run under a churn condition, no damage will be done as long as water is passing through the engine cooling system.)
    a. A fire has occurred or a sprinkler has been damaged that has resulted in a drop in pressure in the sprinkler system. Investigate and confirm that neither has occurred.
    b. A non-return valve is not holding and water is bypassing through this resulting in a drop in system pressure. In the event of a valve bypassing, hold the fuel lever in the “off” position and the diesel engine will go through its abortive start sequence. The engine will crank for fifteen seconds and rest for six seconds for six cycles. After the sixth cycle the pump will not attempt to restart. The “ pump failure” will light up accompanied by the pump failure alarm. The alarm can then be silenced by pressing the “accept alarm” on the annunciator panel. If the “stop/reset ” button is depressed on the diesel engine driven pump controller, the diesel engine will restart.
    Note 3:
    Water must always pass through the drive end side of the gland of the pump even when this is at rest.
    Note 4:
    Always first ensure that water is passing through the cooling system. If there is diesel within the fuel tank and water flowing through the cooling water line, the diesel engine driven pump can be allowed to run under churn conditions without any damage to the unit.
    Note 5:
    It is important to allow the diesel engine to run down completely before releasing the fuel shut off lever. The diesel engine can run in reverse if the fuel lever is released prematurely.
    Note 6:
    If the glands of the pumps are incorrectly packed or the pump incorrectly aligned, the glands will start to heat up immediately and “burn” within two to three minutes. If the collar of the gland is touched every thirty or so seconds on pump start up, a rapid and noticeable rise in heat will be felt. Smoke will be released from the packing accompanied by a crackling sound. At worst, the result of this will be an excessive amount of water passing through the glands.
    Note 7:
    Should the starter motor fail to disengage or engage and disengage rapidly, this is indicative of a faulty proximity switch, tacho-generator or voltage sensitive relay in the panel.
    Note 8:
    Should the starter motor fail to fully engage resulting in a harsh whirring sound, this is indicative of either poor battery condition failing to fully engage the bendix or worn or faulty teeth of either the starter motor or engine ring gear.
    Note 9:
    Cavitation of a pump has a sound similar to that of gravel sliding down a chute. Should this occur it could be a partially open suction valve, an obstruction within the suction line or an excessive flow being allowed through the test pipe when this facet is being recorded.
    Note 10:
    When testing pumps it is important to listen for any excessive or irregular noise or vibration.
    Note 11:
    If the jockey pump is not a centrifugal pump, the boosting pressure must be checked constantly. The peripheral turbine jockey pumps can over pressurise the installation. It is strongly recommended that the jockey pump be replaced with a centrifugal pump as required.
    IMMEDIATELY CEASE TESTING AND CONTACT THE APPROVED SUPPLIER IN ORDER TO ATTEND FAULTS SUCH AS THOSE LISTED ABOVE.

Power Failure Test

  • Isolate the main incoming switch within the pump house distribution board: <br>An alarm bell should sound which should be self-resetting when power is restored<br>

  • Isolate the main isolating switch on the diesel engine driven pump controller. <br>An alarm bell should sound which should be self-resetting when power is restored. <br>

  • Isolate the main isolating switch on the electric motor driven pump controller. <br>An alarm bell should sound which should be self-resetting when power is restored.<br>

Annunciator Panel Test

  • Depress the “lamp test” button on the annunciator panel. <br>Did all the lights on the panel light up? <br>

  • Open the annunciator panel door and check the external condition of the backup batteries.<br>What are the conditions of the batteries?

Jockey Pump Test

  • On the jockey pump controller panel switch the selector switch from “auto” to “manual”. <br>The jockey pump should come into operation and the panel pilot light should illuminate during the run period. <br>When satisfied that this is running correctly switch back from “manual” to “auto”. <br>ENSURE THE SYSTEM PRESSURE DOES NOT EXCEED 1000 kPa.<br>

Pump House Protection: NOTE THAT THIS TEST WOULD NOT BE APPLICABLE IF THE SPRINKLER PROTECTION TO THE PUMP HOUSE WAS FED DIRECTLY OFF THE SPRINKLER CONTROL VALVES INSTEAD OF THE TRUNK MAIN.

  • Set the jockey pump to manual operation. <br>Open the terminal test valve for the pump house protection sprinklers. <br>The flow switch should operate and the “pump house protection” annunciation should light up. <br>ENSURE THE SYSTEM PRESSURE DOES NOT EXCEED 1000 kPa.<br>

Electric Motor Driven Pump (if applicable)

  • Starting:<br>1. Depress the emergency start button. The pump should come into operation. This should be accompanied by a “pump running” light on the panel and the annunciator. <br>2. Allow the unit to run for at least five minutes. During this period note the churn pressure of the pump on the delivery pressure gauge of this unit. <br>3. Once the unit has run press the “stop/reset” button and allow the unit to run down.<br>

  • Churn Pressure from above test in kPa

  • Once the unit is at rest, depress the “test” button.
    The electric motor driven pump should come into operation accompanied by the “fire alarm” annunciation as well as a the flashing beacon and a continuous siren.
    Once satisfied that the unit is operating as intended shut down using the “stop/reset” button.

  • Did the Siren activate?

  • Did the relevant light on the control panel flash?

  • Did the annunciator panel warning activate?

Control Valve Assembly Test

  • Test Procedure:
    With the pump house in a standby condition go to the control valve assembly and test each valve via the 15 mm test valve.
    The valve being tested is to be fully opened on the first set of valves until the installation pressure drops and the alarm valve lifts thus allowing the hydraulic alarm bell to ring.
    The jockey pump should come into operation but should not be able to keep pace with the demand of the 15 mm valve when fully open.
    The electric motor driven pump, (if installed), or the diesel engine driven pump should then come into operation.

    With the pump running, test the hydraulic alarm bell for every set of valves and allow each of the alarm bells to ring for at least thirty seconds

  • Did the main pump come into operation?

  • Valve 1: Did the hydraulic alarm bell operate?

  • Valve 2: Did the hydraulic alarm bell operate?

  • Valve 3: Did the hydraulic alarm bell operate?

  • Valve 4: Did the hydraulic alarm bell operate?

Flow and Pressure Proving :

  • Each pump has a plate fitted to it with a serial number and pump details as well as the rated flow and pressure. Every pump house must have a direct reading flow measuring device or method by which the duty of the pump can be determined.

  • Start the electric motor driven pump. Open the proving test arrangement valve until the desired flow is achieved. Record the flow from the flow gauges and the pressure from the delivery pressure gauge. Close the proving test arrangements valve and shut down the electric motor.

  • Flow achieved (litres per minute)

  • Pressure achieved: (kPa)

  • Start the diesel engine driven pump.
    Open the proving test arrangement valve until the desired flow is achieved.
    Record the flow from the flow gauges and the pressure from the delivery pressure gauge.
    Close the proving test arrangements valve and shut down the diesel engine after five minutes.

  • Flow achieved (litres per minute)

  • Pressure achieved (kPa)
