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.
