** It is advisable that the Installation and Operating manual remains with the
product for the duration of the product lifecycle.
The Grundfos FireSAFE supplies water, usually from a storage tank, via a riser system within
the building to a series of sprinkler heads. When the air temperature around a sprinkler head
reaches a predetermined level, the glass bulb bursts, leading to a loss of system pressure and a
flow of water through the sprinkler head. Only sprinkler heads affected directly by the heat
source will operate.
This loss of pressure is detected by the Grundfos FireSAFE unit, via an internal pressure switch,
activating the pump.
6.0 Key product components (See the diagram in section 5.)
6.1 Pump
From the Grundfos high quality CM centrifugal horizontal multi stage range.
Choice of six sizes available within the FireSAFE (Domestic range).
6.2 Pressure gauge
Providing visual indication of the system pressure/health and for fine-tuning the pressure
switch setting. Range of gauge 0 - 10 bar or 0 - 145 psi.
6.3 Pressure switches (Primary and Secondary)
The FireSAFE unit operates directly from an integrated pressure switch. This pressure switch is
adjusted to meet the site specific requirements. See the section 9.1 regarding Pressure switch
setting. A secondary back up pressure switch is provided in case of failure of the primary
pressure switch. This activates at a factory set value of 1 Bar.
6.4 Non-return valve (NRV)
Included within the product to maintain the system pressure.
Integrated into the 5 way connector.
6.5 BS 9251:2014 Flow test connection and pressure switch testing provision
The FireSAFE unit has an inbuilt provision for a Flow test connection and testing the operation
of the pressure switches.
The Flow test connection is a PTFE sealed 1” plug on the top of the 5 way connector.
If using a flow meter, it is possible that the pipe diameter may need up-sizing, see guide below.
The below provides the necessary diameter for each flow range:
Pipe diameter 1" Flow range –20 - 200 L/min
Pipe diameter 1.5" Flow range –200 - 400 L/min
Pipe diameter 2" Flow range over 400 L/min
Pressure switch testing is performed via the operation of a draincock fitting on the reverse side
of the 5 way connector. A small amount of water is drawn from the draincock to reduce the
system pressure to activate the pressure switch. Care must be taken to minimize the risk of
water spillage and associated issues this may have with any nearby electrical equipment.

6.6 Controller
The Controller has been specifically designed by Grundfos to conform with BS 9251:2014,
integrate key system signals, monitor condition and to operate automatically.
The following are features of the FireSAFE controller:
Modes of operation:
oPressure maintenance
oFire
oService
Integration of digital signals:
oLow water level
oFlow switch
Mains power monitoring / Controller internal fuse monitoring
Semi-automatic learning of the pump condition
Automatic weekly pump health test, including:
oPump fault monitoring
oPump health monitoring
Manual pump health test
Setting of the Automatic weekly pump test time
Annual service reminder (12 months from system verification)
Excessive pump operation / Leak detection (> 10 operations in a 7 day period)
7.0 Description of Controller features
7.1 Modes of operation
The FireSAFE unit can operate in one of three modes:
Mode 1 –System Pressure Maintenance (or “Jockey Pump”)
Mode 2 –Fire
Mode 3 –Service
Mode 1 –System pressure maintenance (or Jockey Pump) mode
If the system pressure decays enough to activate the integral primary pressure switch, the
FireSAFE unit will run the pump for 20 seconds. This will be sufficient to re-pressurise the
system.
The maximum number of maintenance cycles within a 7 day period before the system registers
this as a fault is ten. This excludes the automatic weekly pump self-tests.
On exceeding this the Fault LED on the Control panel and Fault Digital output (D01) are
activated requiring attendance to reset.

GRUNDFOS INSTRUCTIONS
www.grundfos.co.uk Page 8 of 35
Mode 2 –Fire mode (or Main pump/Duty pump).
If the system pressure decays enough again within the next 20 seconds following the system
pressure maintenance mode de-activation the FireSAFE unit will immediately switch to Fire
mode and run the pump continuously until stopped by the return of the system set point
pressure and the pressing of the Test/Reset button on the control panel.
Instructions for setting and adjusting the Pressure Switches can be found in section Pressure
switches setting, section 9.1, along with the factory pressure settings of the FireSAFE.
Mode 3 - Service mode
The FireSAFE unit has a Service mode, the functions include:
Fault status reset
Service status reset
Pump run counter reset (>10 operations in 1 week period)
Pump calibration
To access the service mode follow the below procedure
When in service mode, the ALARM!, SERVICE and FAULT lights will illuminate.
When in service mode the following activities can be undertaken:
Pressing the test button for 1 second will reset all Fault and Service requests and return
to the normal operation.
Pressing and holding the test button for >10 seconds will start the pump condition
learning and return to the normal operation. This will also reset all Faults and Service
requests and return to the normal operation.
(Press and hold the test button until a long beep is heard).

7.2 Integration of digital signals (Low water level switch and Fire alarm device)
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:
Digital input/output (DI2/D02) –Tank 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 sixty seconds before the controller activates the output.
Digital input/output (DI3/D03) –Water flow switch device, the only device allowable under
BS9251:2014 to indicate the presence of a fire and to give an alarm. Water flow switches
normally incorporates an adjustable delay option. This should be optimised to the site
conditions to prevent activating the Fire Alarm unnecessarily.
Consult the documentation supplied with your device.
The digital inputs are “wetted” with a 24 V DC voltage which can be applied to the digital
switching devices. Upon the changeover of the switch condition the digital inputs are relayed to
the volt free digital outputs for integration with an Alarm Control panel, Siren or other device.
The “wetted” inputs supplied by the FireSAFE unit remove the need to supply the signalling
device with power from another source. The inputs are optically coupled to the outputs and
hence voltage/current isolated between each other.
Neither Digital input inhibits the FireSAFE system from operating.
Further details in Electrical Installation section
7.3 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 relay (D01) to moves to its healthy position.
Upon failure of the mains power or the controllers internal fuse the LED extinguishes, the Fault
relay moves to its unhealthy positon and after more than 2 hours without power the internal
buzzer activates for 1 second every 30 minutes. This will continue until the Test/Reset button
is pressed. Buzzer becomes active again at next weekly test.
7.4 Semi-automatic learning of the pump condition
The FireSAFE controller is factory set to the pump full load current (FLC), and it can be reset in
the field following a change to the pump. Follow the service mode instructions in section 7.1.
This should be done against a closed valve system pressurised condition.
