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 run the pump in jockey mode then enter
Possible Fire Mode.
Possible Fire Mode runs the pump until manually stopped via the restoration of pressure in
the system and the pressing and holding of the up and down button on the front of the
controller for 2 Seconds. 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, if installed, 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 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 up and down button on the front of the controller. 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
stops, and the system should be back up to desired pressure. The Auto test result records in
the Log file. A failed Auto test results in the unit flagging a Fault condition.
Auto test can be replicated at any time, see Manual test, see section 3.2
All Controller/Pump activities log in the FireSAFE+ units’ memory for extraction via USB in
report formats.

11 | Page
3.2 Modes of Operation
The FireSAFE+ unit is 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 time period (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 disabled, 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 activates requiring attendance to reset. The FireSAFE+ units’
operation is not impaired.
Possible Fire Mode – One or both pressure switches detected Fire
Following a Jockey Mode operation, the FireSAFE+ monitors the pressure switches during a small
programmable time period. 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 the restoration of pressure in the system and
manually stopped by the pressing and holding of the up and down button on the front
of the controller. 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 generate; hence no contact
made to the Fire Brigade. A Fault alarm will raise.

12 | Page
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 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 up and down button on the front of the controller. 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 solenoid 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 records in the 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 “weekly test”. See section 3.5
3.3 Integration of Signals
The FireSAFE+ unit is 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:
oFlow Switch
oLow Water Level
The Flow switch device is 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 is
reduced below the low-level mark. The signal needs to be present for more than the
programmable delay in the units’ settings 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 connected 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.

3.4 Mains power monitoring / Controller internal fuse monitoring
On the application of mains electrical power, the screen will become visible and 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. 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 are adjustable. See below for instructions on uploading 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 Logging):
•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.
•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 and replace 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 update, 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
change to settings.old. This is a safety measure to prevent accidental reuse. To revert the
settings.old file to settings.txt simply rename the extension back to .txt.
Time and date enable an approximate time/date to be set on the FireSAFE+ for time stamping
of activity logs.

4.4 Site storage
It is strongly recommended once the FireSAFE+ unit has been delivered to site, that it is
placed immediately into a dust, moisture and frost-free area which has been secured to
prevent unauthorised interference.

20 | Page
4.5 Frost protection
The FireSAFE+ unit must be protected from freezing conditions. The unit may
require trace heating or lagging. If the FireSAFE+ unit is being stored during
periods of frost the whole unit should be drained to avoid damage. Remove all
drain and vent plugs and allow the pump to drain. Do not replace the plugs
until the FireSAFE+ unit is to be used again.
The pump must be vented/primed before it is
started again. Loosen but do not remove the
priming screw until water flows from the hole.
4.6 Operating environment
The FireSAFE+ unit must not be used in an environment which has been
classified as hazardous where it could provide a source of ignition and
therefore cause an explosion by flame path.
Grundfos do not accept any responsibility for the use of FireSAFE+ unit to pump liquids
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
during a Fire and during the winter. Provision to maintain the FireSAFE+ ’s
operating conditions needs to be made within the overall system design.
The FireSAFE+ unit should be sited in a dry, well ventilated, and frost-free
position, where it will not be subjected to extremes of temperature.
The FireSAFE+ may be located outdoors in a weather, frost, and rodent proof
enclosure with adequate ventilation especially during hot weather. All pipe work
subject to freezing conditions must be adequately protected. Alternative system
provision must be made for alerting the inhabitants to the FireSAFE+ warnings
and alarms.
To enable maintenance and service of the FireSAFE+ unit to be carried out
satisfactorily, the area should have adequate lighting for this work to be carried
outsafely.
