** 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 

 

6.1 Pump 
From the Grundfos high quality CR centrifugal horizontal multi stage range.  
Further details on the FireSAFE Data sheet 

 

6.2 Pressure gauge  
Providing visual indication of the system pressure and for fine tuning the pressure switch 

setting. Depending on pump size the Range of the Gauge is 0 - 10 bar or 0 – 16 bar. 

 
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 
Included within the product to maintain the system pressure. 
 
6.5 Flow Switch  
Included within the product and is used to indicate the presence of a fire and give an alarm as 

the only device allowable under BS9251:2014. The flow switch provided incorporates an 
adjustable delay option. This should be optimised to the site conditions to prevent activating 
the Fire Alarm unnecessarily 
 

6.6 BS 9251:2014 test line connection 

The FireSAFE unit includes a 1” Test line with lockable ball valve. The FireSAFE CR only includes 

provisions (1” blanked BSP port) for this test line. This facilitates the annual system test to be 
performed according to BS 9251:2014. 

 

Care should be taken when connecting onto this port, to minimize risk of water spillage and 

associated issues this may have with any nearby electrical equipment. The unit should be fully 
isolated before using this port.
