ICAF System with Electric Fail-safe Release
1. Description
The ICAF System utilizes a Flow Control valve (B14) to
control water flow into system piping equipped with open
rotating spray nozzles. The system piping remains empty
until the Flow Control Valve is activated by operation of the
release system.
In fire condition, when the detection condition is satisfied the
ARC-1 Control Panel energizes the Solenoid Valve
(R2)
open, the pneumatic control line is then pressurized causing
the water, air and foam pneumatically activated control
valves
(A1, B9 & F1) to open simultaneously and generate
the CAF through a piping system into the discharge devices
and to be discharged over the area served by the discharge
devices.
Electric Fail-Safe Release means that if the AC Power fails
and the battery backup expires while the system is operating,
the system will fail-safe, and continue flowing until AC Power
is restored or the system is manually shut-off
2. Normal conditions
1. ARC-1 Control panel of the ICAF System:
a) Green LAMP for power is activated in continuous
manner.
b) All other LAMPS are deactivated.
c) Alpha-numeric Display shows default screen
" SYSTEM NORMAL"

b) All upstream water supply valves are OPEN.
c) Priming valve
(B1) is OPEN.
d) Flow test valve (B6) is CLOSED.
e) System main drain valves (B16) are CLOSED.
f) Alarm test valve (B5) is CLOSED.
g) Manual emergency release valve (R1) is CLOSED
(handle in NORMAL position).
h) System flushing valve (A3) is CLOSED.
i) Foam injector flushing valve (F5) is CLOSED.
j) All gauge valves are OPEN.
3. Gauges:
a) Water supply (B12) - at water supply pressure
b) Priming chamber (B11) - should be equal to, or
higher than, water supply pressure (B12).
c) Air supply pressure (A4) is between 100-135 psi.
