1.7  RELEASING 

Release trim for the double interlocked preaction 
system  with  electric / pneumatic  release  utilizes  a 
normally closed solenoid valve 

(F1)

 controlled by the 

Viking VFR-400 integrated control panel with a 
compatible detection system (supplied by others)  and a 
pneumatic actuator 

(F3)

 normally held closed by 

supervisory air pressure maintained in the sprinkler 
piping. 

In fire condition, when the detection condition is fulfilled, 
the control panel energizes the solenoid valve 

(F1)

 and 

an open sprinkler releases the supervisory air pressure 
from the sprinkler piping.  

Both

 the electric detection 

condition 

and

 supervisory pressure relieved from the 

sprinkler piping are necessary before the deluge 
valve 

(A1)

 will open and fill the sprinkler piping with 

water.  Water will flow from any opened sprinklers in the 
system piping.
