3.0 Installation and Operating Instructions
Original Installation and Operating Instructions
3.1 Sequence of Operation
The Grundfos FireSAFE+ supplies water, usually from a storage tank, via a riser system within
the building to a system of sprinkler heads.
Should the pressure in the sprinkler system decay, through minor leakage, then the FireSAFE+
unit will detect this pressure drop, via inbuilt pressure switches and run the pump to
re- pressurize the system (Jockey Mode). If the pressure switches remain active or re-activate
within a small-time window, then the FireSAFE+ will enter Possible Fire Mode.
Possible Fire Mode runs the pump until it is manually stopped via the restoration of pressure
in the system and the pressing and holding of the Reset button on the front of the cabinet.
If the unit is connected to a Fire Alarm panel, it will send a Fault signal from the FireSAFE+ unit
to the Fire Alarm Panel. During Possible Fire Mode the cooling line is active. This protects the
pump from a potential no flow condition.
Should a sprinkler head activate then the resulting flow in the system will trigger the system
flow switch which will report a flow of water to the FireSAFE+ unit which in turn will put the
pump in Fire Mode. Fire Mode runs the pump until it is manually stopped via the restoration
of pressure in the system, resulting in the end of the flow signal, and the pressing and holding
of the Reset button on the front of the cabinet. If the unit is connected to a Fire Alarm panel, it
will send a Fire signal from the FireSAFE+ unit to the Fire Alarm Panel.
The FireSAFE+ unit also performs an Auto test on a weekly basis to ensure that it is fault free
and the pump is available on demand. During this test the Cooling line valve opens, releasing a
small amount of water, causing a system pressure drop. The controller monitors both pressure
switches and detects the drop in pressure. The controller activates the pump and continues to
monitor. It runs the pump to increase the pressure until it detects the de-activation of both
pressure switches. Upon de-activation of both pressure switches, the pump is stopped, and
the system should be back up to desired pressure. The Auto test result is recorded in the Log
file. A failed Auto test results in the unit flagging a Fault condition.
Auto test can be replicated at any time, Refer to section 3.2
All Controller/Pump activities are logged in the FireSAFE+ units’ memory for extraction via USB
in report formats.

11 | P a g e
3.2 Modes of Operation
The FireSAFE+ unit has been specifically designed by Grundfos to assist system designers
and installers with complying to the BS, EN and LPS standards, integrating key system
signals, monitoring system conditions and to operate automatically.
The FireSAFE+ controller has the following modes of Operation:
oJockey Mode - Pressure maintenance
oPossible Fire Mode –Pressure Switch triggered only
oFire Mode –Flow switch confirmed Fire
oAuto Test Mode –Weekly self-test
oManual Test Mode –Same as Auto Test Mode
Jockey Mode –System pressure maintenance.
If the system pressure decays enough to activate one or both pressure switches, the
FireSAFE+ unit will run the pump for a programmable short period of time (Factory set at
10 seconds). This should be sufficient to re-pressurize the system.
The maximum number of maintenance cycles within a 7-day period before the system
registers this as a fault is programmable up to a maximum of 30 (Factory set at 10
starts/week). It can also be programmed off, but this is the responsibility of the installer/user
thereafter. This cycle count excludes the automatic weekly pump self-tests.
On exceeding the maximum maintenance cycles the Fault LED on the Control panel
and Fault Digital output is activated requiring attendance to reset. The FireSAFE+ units’
operation is not impaired.
Possible Fire Mode –Dual Pressure switch detected Fire, Flow switch failure
Following a Jockey Mode operation, the FireSAFE+ monitors the pressure switches during a
small programmable time frame window. If the pressure switches remain active or re-activate
during this time window, the FireSAFE+ will run the pump in Possible Fire Mode.
Possible Fire Mode runs the pump until it is manually stopped via the restoration of
pressure in the system and the pressing and holding of the Reset button on the front
of the cabinet. Possible Fire Mode activates the Fault LED on the Control panel and
Fault Digital output requiring attendance to reset. The FireSAFE+ units’ operation is not
impaired.
During Possible Fire Mode the cooling line is active, protecting against running the pump
against a potential no flow condition. A Fire Alarm signal will not be generated; hence no
contact will be made to the Fire Brigade. A Fault alarm will be raised.

12 | P a g e
Fire! Mode –Flow switch = Confirmed Fire
Should a sprinkler head activate then the resulting flow in the system will trigger the system
flow switch which will report a flow of water to the FireSAFE+ unit which in turn will put the
pump in Fire Mode. Fire Mode runs the pump until it is manually stopped via the restoration
of pressure in the system, resulting in the end of the flow signal, and the pressing and holding
of the Reset button on the front of the cabinet. Fire Mode activates the Fire! LED on the
Control panel and Fire Digital output requiring attendance to reset.
Auto test Mode –Weekly test
The FireSAFE+ unit performs an Auto test on a weekly basis to ensure that it is fault free and
the pump is available on demand. During this test the cooling line valve opens, releasing a
small amount of water, causing a system pressure drop. The controller listens for the
activation of both pressure switches then runs the pump to restore the pressure while
listening for the de-activation of both pressure switches.
The Auto test result is recorded in the Autotest Log file. A failed Auto test results in the
activation of the Fault LED on the Control panel and Fault Digital output requiring attendance
to investigate the problem and reset.
Manual test Mode
Auto test can be replicated at any time, this is called the Manual test. Refer to section 3.5
3.3 Integration of Signals.
The FireSAFE+ unit has been specifically designed with the ability to power and relay
digital signals. The signals could be from any source, but Grundfos suggest the following
important signals are used:
oFlow Switch
oLow Water Level
The Flow switch device, the only device allowable under BS9251:2021 to determine the
presence of a fire and to activate Fire Mode. Water flow switches normally incorporate an
adjustable delay option. This should be optimized with the programmable delay in the
controller to the site conditions to prevent activating the Fire Alarm unnecessarily or delaying
Fire activation. Consult the documentation supplied with your device.
The Low water level switch device, to give a warning once the water storage capacity has
been reduced below the low-level mark. The signal needs to be present for more than the
programmable delay in the units’ settings, Factory set at 3 seconds, before the controller
activates the output.
The digital inputs are supplied with a current limited 12V DC Voltage which can be applied to
digital switching devices. Upon switching, the digital inputs are coupled to the volt-free
outputs. This allows Volt-Free output to Alarm Control Panels, Sirens, etc.
Voltage wetted inputs negate the requirement for an additional power source to supply the
digital signalling device. The inputs are optically connected to the outputs and therefore
voltage/current isolated from each other.

13 | P a g e
3.4 Mains power monitoring / Controller internal fuse monitoring
On the application of mains electrical power, the Power LED on the controller front
panel illuminates and the Fault output moves to its healthy position.
Upon failure of the mains power or the controller’s internal fuse the LED extinguishes, the
Fault relay moves to its unhealthy position and after more than 2 hours without power the
internal buzzer activates for 1 second every 30 minutes. This will continue until the mains
power is restored or the internal battery fails. The loss of mains power and the restoration of
mains power are both recorded in the data logs.

3.7 Programming settings
FireSAFE+ is factory-configured with standard settings that should be suitable for most
installations. These settings should be verified onsite by the commissioning engineer. Where
required, these settings can be changed. See below for instructions on downloading advanced
settings from a USB memory stick.
The USB configuration feature is intended for use by qualified installers ONLY.
Changing the settings incorrectly could result in the system failing to operate correctly.
USB device requirements:
Formatted FAT32, Size 1Gb < > 65Gb, no other files on the device, root directory
only to be used (no folders).
This process is only for suitably qualified electrical persons, not the end user.
Process: (Programming settings/Extracting Data Logs):
•TURN OFF - Follow a Safe Isolation Procedure before working on the unit.
•Remove the Front cover and lay it flat, face down on a soft surface to
prevent scratching of the paint.
•Remove the Red plug in the PCB cover.
•Insert USB memory stick device into the USB port.
•Turn ON, wait a few seconds for the unit to beep.
•TURN OFF - Follow a Safe Isolation Procedure before working on the unit.
•Remove USB memory stick device, replace the Red plug, re-assemble the
Front cover.
Programming settings
A text file called settings.txt, available from Grundfos, can be used to customize the unit values
with the aid of a laptop before saving these to the USB device. Then performing the process
described above.
This text file is pre-formatted and allows for the customization of settings by editing the values
with a laptop/pc in the Windows Notepad editor.
Settings files MUST follow the settings.txt file syntax exactly.
Additional or missing characters and spaces are not permitted and may prevent correct
operation. All text after the semi-colon (;) are comments only and are not used by the system.
The USB configuration feature is intended for use by qualified installers ONLY.
Changing the settings incorrectly could result in the system failing to operate correctly.
On completion the unit will be updated, USB device will have a record saved to it from the
FireSAFE+ unit of the settings and history before the change. The settings.txt file will also have
been changed to settings.old. This is a safety measure to prevent it be accidentally used again.
To revert the settings.old file to settings.txt simply rename the extension back to .txt.
Time and date enables an approximate time/date to be set on the FireSAFE+ for time stamping
of activity logs.

16 | P a g e
3.8 Extracting Data logs
Perform the above process. The USB memory device will now have 4 text files on.
•Autotest Log
(records results of all Autotest cycles, Auto or Manually initiated)
•Fault
(records the number and name of the fault and when it occurred)
•Configuration

which could be construed as being hazardous to health either by touch, ingestion or
inhalation of fumes or gases given off by the liquid.
4.7 Installation location
Careful consideration must be given to the location of the FireSAFE+
unit. The following are minimum requirements:
The FireSAFE+ unit should ideally be placed in a location where the Control
panel LEDs can readily be seen, and the internal buzzer heard without
obstruction.
These are primary warning and alarm events and should be available to be
observed and heard. Additional system provision for alerting the inhabitants to
the FireSAFE+ warnings/alarm must also be made.
The FireSAFE+ also needs to be protected against the extremes of temperature
such as during a Fire or during the winter. Provision to maintain the FireSAFE+
within operating conditions needs to be made within the overall system
design.

FireSAFE+ suction and discharge ports, as a smaller size may result in reduced
pump performance or increased system resistance leading to a reduced flow.
The installation suction and discharge pipework may need to be properly
supported before being connected to the FireSAFE+ unit so that the FireSAFE+
unit is not stressed.
The pipework installation to and from the FireSAFE+ unit should be in
accordance with local water authority regulations, best industry practice and
