1. Product Description

The AquaGuard fire pump controller has been designed as an easy to install, all in one

solution to control the operation, monitoring and automatic testing of the fire pump in

accordance with BS9251:2021.

Incorporating an informative LCD display, easy to use interface and a 128 event log

making the AquaGuard fire pump controller the most advanced on the market.

Features

Jockey Mode - Upon pressure loss the pump will operate, if no flow is detected then

pump will shut off after 1 minute. Jockey limit fault will indicate if Jockey starts have

exceeded weekly limit.

Fire Mode - If pressure loss and flow are detected by either of the two pressure switches

and the flow switch then pump will operate in fire mode until manually shut down.

Test Mode –Each Monday at 10am the controller will open the solenoid valve until both

the pressure switches are activated and run the pump checking voltage/current and

power are within set parameters.

Maintenance - Maintenance interval is pre-set to every 12 Months but can be adjusted

to suit specific interval requirements. Maintenance due indicator will require a physical

flow test to reset.

Event Log - Event log up to 128 entries can be accessed on the control panel.

4. Controller Set Up and User Guide

4.1 –Once controller has been wired as per diagram (Fig.1) the controller power supply

can be switched on, please note that on initial power up the pump will run to reach

system pressure, please ensure that all suction valves are open and pump has been fully

primed and free of any air before switching on for the first time.

It is recommended to proceed to fill the entire sprinkler system shortly after powering

on for the first time and leave the pump delivery valve open to create volume in the

pump manifold, this is to ensure the pump will not repeatedly enter ‘Jockey mode’

caused by the stopping of the pump triggering the pressure switch due to the small

volume in the pump manifold.

Warning: Tank must be full, pump must be fully primed from all bleed nipples and all

suction valves must be open prior to powering the controller up for the first time.

4.2 –Shortly after switching the controller on for the first time, once system pressure

(Pmax) has been made the controller will start a 1 minute countdown indicating ‘Jockey

Mode’ press the ‘Stop’ button and the home screen and green power led should be

visible as image below. If the ‘Spr Activation’ is displayed press the ‘Reset’ button to

reset.

4.3 –Setting Time and Date

From the home screen display, press the up key until the time and date are visible on

display, then press the left and right keys at the same time to edit. Use the up, down,

left, right keys to set time and date then press ok (tick) button to set. Press the down key

until the home screen is displayed. Note: date is in the format of MM/DD/YYYY.

4.5 –Jockey Limit Reset

If the pump has entered jockey mode five times or more within a week then the ‘Jockey

Limit’ fault will be displayed, this may also be displayed shortly after start-up/initial filling

of the system. To reset the ‘Jockey Limit’ initiate a weekly test procedure by following

the steps in 5.3.

4.6 –Pump Running Indicator

A ‘Pump Running’ fault will be displayed If the fire sprinkler pump was to run for more

than one minute, this is to meet the requirements of BS9251:2021 to ensure in the event

of a fault whereby the pump was running when not called upon then a fault signal is

transmitted. Note: This fault will be present when operating the pump set in ‘Fire Mode’

for more than one minute, this will reset automatically when stopped.

4.7 –Internal Audible Alarm (Optional)

The optional internal audible alarm powered by a 9v battery will make an audible bleep

when any fault condition arises including power failure to the pump controller. This

audible alarm should be requested where the standard fault output contacts cannot be

monitored. Note: Selecting internal audible alarm option will as standard remove the

fault output contacts.

Supplied 9v battery to be inserted into the battery carrier on the underside of the

controller.

5. Commissioning

5.1 –Filling the system

If the sprinkler system was not filled upon initial power up in step 4.1, please proceed to

filling the system, this may activate the alarm output therefore it may be required to

temporarily isolate the alarm. Once system pressure (Pmax) has been made the

controller will start a 1 minute countdown indicating ‘Jockey Mode’ press the ‘Stop’

button and the home screen and green power led should be visible. If the ‘Spr Activated’

is displayed press the ‘Reset’ button to reset.

5.2 –Setting of Pressure Switches (if required)

The pressure switches are pre-set from the factory to suit the associated pump but it

may be required by the installer to adjust the pressure switches from factory set

pressure, it is recommended that the system pressure switches be set at least 1 bar

below system ‘Pmax’ and no less than the pressure required from the ‘most

unfavourable hydraulic calculations’, it is recommended that the pressure switches are

set within 0.3 bar of each other. Refer to pressure switch instruction manual for setting

instructions, this should be undertaken with the Aquaguard pump controller switched

off.

5.2 –Flow Test

From the pump test valve, a flow test should be undertaken to check pump satisfies the

flow and pressure requirements set out in the system Hydraulic Calculations, after 20

seconds of the system flowing the ‘Spr Activated’ will appear triggering the alarm output.

Once flow test has been completed and system repressurised press the ‘Stop’ button

then ‘Reset’ button to return to home screen.

5.3 –Weekly Test

To manually initiate a weekly test to ensure correct operation of solenoid etc, press and

hold the black button on the bottom of the controller for at least 10 seconds, this will

initiate the weekly test to start, opening the solenoid valve until both pressure switches

are activated and run the pump for 60 seconds checking voltage/current and power are

within set parameters.

If either of the pressure switches are not detected, then a fault will be displayed

indicating either ‘PS1 not detected’ or ‘PS2 not detected’.

6. Annual Maintenance

6.1 –Annual Maintenance Reset

12 Months from system commissioning the ‘Maintenance 1 Requested’ fault will be

displayed; this will not trigger the fault output unless requested. This maintenance fault

can only be reset by undertaking an annual flow test and no faults other than

‘Maintenance 1 Requested’should be present, the reset procedure cannot be completed

until faults are rectified.

To reset annual maintenance, undertake the following procedure.

1. Undertake a flow test as per section 5.2, please note if flow detected for more

than 15 seconds the alarm output will be triggered. Once finished press the ‘Stop’

button followed by the ‘Reset’ button.
