9. Depress the plunger of the Drip Check Valve (B7) . No
water should flow from the Drip Check when the plunger
is pushed.
10. Open air supply, (Refer to AIR SUPPLY section for
details).
11. Place the foam supply in SET condition, (Refer to FOAM
SUPPLY section for details).
12. Check and repair any leaks.
13. On new installations, systems that have been placed out
of service, or where new equipment has been installed,
trip test system to verify that all equipment functions
properly. Refer to INSPECTION & MAINTENANCE –
ANNUALLY section for instructions.
CAUTION ! Performing a trip test results in operation of the
ICAF System. CAF will flow into the distribution piping.
Take necessary precautions to prevent any damage.
14. After completing the trip test, perform instructions in
INPECTION & MAINTENANCE – SEMI-ANNUALLY
section.
Note: When a valve has been removed from service and is
subject to freezing or will be out of service for an
extended period of time, all water must be removed
from the priming chamber, trim piping, water supply
piping and any other trapped areas.
15. Notify the Authority Having Jurisdiction, remote station
alarm monitors, and those in the affected area that the
system is in service.

1. System Operation
In the SET condition:
System water supply pressure enters the priming
chamber of the Flow Control Valve
(B14) through the
priming line which includes a normally open priming
valve
(B1) , strainer (B2) , restricted orifice (B3) and spring
loaded check valve (B4).
System air supply pressurizes the normally closed air
pneumatically operated control valve (A1) , and the
pneumatic control lines .
Electric Fail Safe Release: In the SET condition, water
supply pressure is trapped in the priming chamber by a
spring loaded check valve
(B4) and the normally closed
Water pneumatically actuated control valve (B9). The
pressure in the priming chamber holds the Flow Control
Valve
(B14) clapper closed, keeping the outlet chamber
and system piping dry.
System air supply pressurizes the normally closed air
pneumatically actuated control valve (A1) and the
normally closed Solenoid Valve (R2) prevents the air to fill
up the pneumatic control lines, keeping the system
closed. The control line vent Solenoid Valve is
closed
(R4) .
Electric Release: In the SET condition, water supply
pressure is trapped in the priming chamber by a spring
loaded check valve
(B4) and the normally closed water
pneumatically actuated control valve (B9). The pressure
in the priming chamber holds the Flow Control Valve
(B14) clapper closed, keeping the outlet chamber and
system piping dry.
System air supply pressurizes the normally closed air
pneumatically actuated control valve (A1) and the
normally closed Solenoid Valve (R2) prevents the air to fill
up the pneumatic control lines, keeping the system
closed.
Pneumatic Release: In the SET condition, water supply
pressure is trapped in the priming chamber by a spring
loaded check valve
(B4) and the normally closed water
pneumatically actuated control valve (B9). The pressure
in the priming chamber holds the Flow Control
Valve
(B14) clapper closed, keeping the outlet chamber
and system piping dry.
System air supply pressurizes the normally closed
air
pneumatically actuated control valve (A1) and the
pneumatic release system. The Pneumatic Actuator (R5)
is held closed by pressure maintained in the pneumatic
release system, preventing the air to fill up the pneumatic
control lines, keeping the system closed.
Manual Release: In the SET condition, water supply
pressure is trapped in the priming chamber by a spring
loaded check valve
(B4) and the normally closed water
pneumatically actuated control valve (B9). The pressure
in the priming chamber holds the Flow Control
Valve
(B14) clapper closed, keeping the outlet chamber
and system piping dry.
System air supply pressurizes the normally closed air
pneumatically actuated control valve (A1). The normally
closed Emergency Release Valve (R1) prevents the air to
fill up the pneumatic control lines, keeping the system
closed.
In a FIRE condition:
Electric Fail Safe Release: When the detection system
operates, system Control Panel activates an alarm and
energizes normally closed Solenoid valve
(R2) to open.
Electric Release System: When the detection system
operates, system Control Panel activates an alarm and
energizes normally closed three way Solenoid valve
(R2)
to open.
Pneumatic Release System: When a releasing device
operates, pressure in the pneumatic release system
escapes, causing the Pneumatic Actuator
(R5) to open.
Manual Release: When the Emergency Release
Valve (R1) is opened, the pressure control line is
pressurized and the pneumatically actuated control
valves for water (B9) , air (A1) and foam (F1) are all
opened simultaneously.
