1.4.4 Manual operation
Anytime the handle of the manual emergency release
valve
(B10)
is triggered, pressure is released from the
priming chamber of the flow control valve
(A1)
causing
flow control valve to open. Water will flow into the system
piping network and alarm devices
(C1
and optional
C2)
will
operate
.
Water will flow from all open sprinklers/spray
nozzle on the system piping network. The PORV
(B9)
will
keep the flow control valve
(A1)
open.
1.4.5 Fail-safe condition
In case of AC power loss following a cycling discharge
stop, if the main water supply valve
(D1)
is still open while
the batteries have reached their cycle end, the normally
open solenoid valve
(F2)
will be de-energized, causing the
flow control valve
(A1)
to reopen with the help of the
PORV
(B9)
.
