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.
Setup Mode - All settings can be changed if required with the use of an advanced user
password to prevent unauthorised access to settings.

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.

maintenance and view event log the Aquaguard controller has a user-friendly
menu interface, to access press the Button, icon descriptions are indicated
below.
2. Most functions can be accessed without the use of a password but to gain access
to the command’s menu or setup menu then a password will need to be entered.
To access the Commands menu, navigate to ‘Enter Password’ (key icon), enter the
user password ‘2000’, press right to the key symbol then press ok (tick).
Note: Access to the setup menu is possible by entering an advanced password but
the installer will be required to speak to Aquaguard technical to obtain and discuss
required changes, as any changes in this menu without technical guidance could
affect operation and invalidate warranty.
3. Within a short period of entering the password, re-enter main menu, navigate to
‘Commands Menu’. To enter commands you must first hold the ‘Manual Mode’
button located on the underside of the controller (below) and press ok on the

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.
2. Following the same password and button entry procedure in section 4.4, enter
main menu, navigate to the ‘Enter password’ section, enter code ‘2000’ then press
