Configuration Description
An ICAF system is a fixed deluge-type fire suppression
system which totally floods an area or hazard with
compressed air foam through a piping system of open
nozzles. The system piping is empty until the system is
activated by a pneumatic, electric or manual release system.
Single zone configuration can be used to protect smaller
hazards whereas multiple zones and multiple mixing
chambers configurations can be used to protect larger
hazards or a combination of smaller independent hazards.
System requires a reliable and automatic water supply. Air
supply is provided by compressed air cylinders mounted on a
skid and includes an air pressure regulator. Foam
concentrate is contained inside a stainless steel tank. Upon
system activation, the foam concentrate tank is pressurized
and water, air and foam concentrate are injected and mixed
together inside a mixing chamber. Compressed Air Foam is
then generated and moves inside the piping network toward
the distribution nozzles.
ICAF system trims including water, air and foam controls,
CAF mixing chamber and release system is factory
assembled in cabinets and available in self-contained,
remote controlled and extension unit configurations to suit
project's requirements. A description of the available units
follows:
អ អ អ អ Self-Contained Unit: This unit includes all the
mechanical controls & trims, CAF mixing chamber(s) and
is provided with the release control panel.
Components size and quantity of mixing chambers are
determined by the system's flow and configuration
required to supply the nozzles in the hazard(s).
អ
អ អ
អ Remote Controlled Unit: This unit is used when an
additional zone is required to be protected by the same
system. This unit includes all the mechanical controls,
trims and CAF mixing chamber(s) and is provided with a
field wiring junction box in lieu of the releasing control
panel enclosure. This should then be connected to the
control panel of the self-contained unit.
Components size and quantity of mixing chambers are
determined by the system's flow and configuration
required to supply the nozzles in the hazards.
អ អ អ អ Extension Unit: This unit is used when additional mixing
chambers are required to supply a single zone with a
larger amount of nozzles. This unit includes the CAF
mixing chamber(s) without any controls or releasing
control panel. It should be used in parallel with a self-
contained unit or a remote controlled unit.
Water Supply
CAF technology offers an important reduction in the water
supply requirements compared to standard sprinklers or
foam systems. The system can operate with a water
pressure in the range of 50 to 175 psi (345 to 1206 kPa).
The ICAF system is dependable, automatic and capable of
providing the required flow and pressure for the required
duration.
ICAF system uses pneumatically actuated globe valves for
¾" (20 mm) diameter or Listed fire protection flow control
valves for 1½" (40 mm) diameters and up.
All the valves are rated up to a maximum of 175 psi WWP
(1206 kPa) and are available in the following diameters:
អ អ អ អ ¾
" (20 mm)
អ អ អ អ
1½" (40 mm)
អ អ អ អ
2" (50 mm)
អ អ អ អ
3" (80 mm)
When water pumps are required for system operation, they
shall be designed and installed in accordance with NFPA 20,
Standard for the Installation of Centrifugal Fire Pumps .
The water system shall be designed and installed in
accordance with NFPA 24,
Standard for the Installation of
Private Fire Service Mains and their Appurtenances . A
strainer shall be provided on water supplies containing solids
likely to clog orifices. Such strainers shall be provided with a
cleanout port and shall be arranged to facilitate inspection,
maintenance and replacement.

Air Supply
CAF is 90% compressed air. Air is provided by cylinders
bank as described in the
AIR SUPPLY SECTION F .
The connection is used to supply compressed air between
the cylinders bank and the ICAF system. The piping is factory
prepared according to installation arrangement and is
supplied with the system. The system can be configured for:
អ អ អ អ Single air interconnection line
