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 BS9251:2014.
Incorporating an informative LCD display and optional Mobile App to assist programming
and view/save event logs 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 2 minutes.
Fire Mode - If pressure loss and flow are detected pump will operate in fire mode until
manually shut down.
Test Mode –Each Monday at 10am the controller will open the solenoid valve until the
pressure switch is activated and run the pump checking voltage/current and power are
within set parameters. Current check only version will test at the same time running 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 or
downloaded from the Mobile App via the IR dongle*.

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 2 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 ‘Sprinkler activated’ is displayed press the ‘Reset’ button to reset.
5.2 –Setting of Pressure Switch
The installed pressure switch may need adjusting from factory default settings, it is
recommended that the system pressure switch be set approximately 0.5 bar above
pressure required in the ‘most unfavourable hydraulic calculations’. 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 15
seconds of the system flowing the ‘Sprinkler 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 force a weekly test to ensure correct operation of solenoid etc, using the instructions
set out in ‘4.4 – Setting Time and Date’ adjust the time to a Monday at 09.58, press ok,
then press the down key until the home screen is displayed.
Within two minutes the weekly test will start, opening the solenoid valve until the
pressure switch is activated and run the pump for 60 seconds checking voltage/current
and power are within set parameters. Current check only version will run the pump for
60 seconds checking voltage/current and power are within set parameters.
Once test is completed, repeat the steps in 4.4 to reset to correct time and date.
