General 

1.  Applicable Standards 

Design  and  installation  of  CAF  (Compressed  Air  Foam) 
system  is  covered  by  chapter 7  of  the  NFPA 11.    Complete 
design  and  installation  shall  be  prepared  in  full  accordance 
with 

F

IRE

F

LEX 

's Design Manual (FM-090M-0-01). 

Working  plans  shall  be  prepared  only  by  persons  fully 
experienced and qualified in the design of fixed Compressed 
Air  Foam  systems.    Working  plans  shall  be  reviewed  by 

F

IRE

LEX 

's  engineering  department  prior  to  installation.    No 

deviation from these documents shall be made without prior 
permission from

 Systems Inc. 

Before  the  installation,  the  contractor  installing  the  system 
shall be familiar with the following documents and standards: 

-

  NFPA 11, Standard for Low, Medium and High-Expansion 

Foam  

-

  NFPA 13, Standard for the Installation of Sprinkler 

Systems; 

-

  NFPA 72,  National Fire Alarm Code; 

-

  Applicable Local & State Building Codes; 

-

  Any additional requirements of the Local Authority Having 

Jurisdiction. 

2.  Listings and Approvals 

In  addition  to  being  fabricated  under  strict  ISO-9001 
manufacturing  and  quality  control  procedures,  your  ICAF 
system  has  also  been  tested  and  approved  by  Factory 
Mutual  Research  <FM>  under  the  heading:  "Integrated 
Compressed Air Foam Extinguishing System for Fixed Piping 
Networks,  "Class 5135"  when  installed  with  specific 
components. 

CAUTION !  

Any unauthorized modification or addition made 

on-site  to  a  factory  built  Approved  system  will  void  this 
Approval.    Such  modifications  or  additions  may  also  void 
the system's warranty as well.  Consult 

F

IRE

Systems 

Inc.  Engineering  Department  before  proceeding  with  any 
such modifications or additions. 

3.  Environment 

The  ICAF  system  shall  be  installed  in  a  dry  and  clean 
location.    Verify  that  all  equipment  is  properly  heated  and 
protected to prevent freezing and physical damage. 

The system and its components must be kept free of foreign 
matter, 

freezing 

conditions, 

corrosive 

atmospheres, 

contaminated  water  supplies,  and  any  condition  that  could 
impair its operation or damage the components. 

The  frequency  of  the  inspections  and  maintenance  will  vary 
depending on these environmental conditions.  The owner is 
responsible  for  maintaining  the  fire  protection  system  and 
devices in proper operating condition. 

4.  General Description 

CAF  (Compressed  Air  Foam)  is  formed  by  combining  air 
under  pressure,  water  and  foam  concentrate  in  the  right 
proportions, and then sending it through piping for distribution 
on the protected area. 

 

ICAF  (Integrated  Compressed  Air  Foam)  system  for  fixed 
piping  networks  consist  of  a  complete  system  including  the 
compressed  air  supply  equipment,  the  water  control  valve, 
the foam tank and a mixing chamber, all pre-assembled, pre-
wired  and  factory  tested.    All  electrical  and  mechanical 
components of the system are contained in single or multiple 
units and ready to be connected to a fixed piping network.   

The CAF is carried using standard piping network as used for 
conventional  sprinkler  or  foam  systems.    To  distribute  the 
CAF  over  the  hazard  area,  nozzles  specially  developed  for 
CAF are used.  These nozzles are offered in different types 
for  various  applications.    The  nozzles  are  rotary  type  and 
insure uniform CAF distribution over the protected area. 

A  detection  network  is  used  in  parallel  with  the  open  type 
nozzles.  This network may be pneumatic or electric and may 
be  actuated  by  manual,  fixed  temperature,  rate-of-rise 
temperature,  smoke  or  other  means.    When  the  detection 
system  operates,  it  gives  an  alarm  and  activates  the  ICAF 
system.    Because  ICAF  systems  are  often  used  in  extra-
hazard  occupancies,  electrical  and  pneumatic  detection 
systems are by far the most common. 

The connections required for installation are the water supply 
inlet,  the  compressed  air  and  the  foam  concentrate 
interconnection  with  the  system  trim,  CAF  discharge  outlet, 
open type main drain, electrical connections with air cylinders 
pressure  transducer,  water  tank  low  level  switches  (when 
applicable)  and  the  electrical  detection  and  alarm 
connections.    The  discharge  outlet  is  connected  to  a  fixed 
piping system of open nozzles. 

The  ICAF  system  is  supervised  in  order  to  monitor  its 
integrity.    The  electrical  detectors  and  associated  wiring  are 
also supervised. 

Note:  

Each  ICAF  system  and  mixing  chamber  is  identified 

with  its  unique  serial  number,  which  format  is  ARC00000 
or  NFS00000  and  MIX00000.    This  number  is  located 
inside the cabinet and on a sticker on the mixing chamber.  
It  is  used  as  a  reference  to  maintain  records  in  our 
computerized  data  base.    Have  these  serial  numbers 
handy when calling for information on your unit. 

5.  Features 

Your  ICAF  system  is  superior  to  many  other  products 
available on the market now and has been manufactured by 
the company that has introduced and developed the concept 
of integrated fire protection systems on the market. 

Main features are: 

-

  Very efficient suppression capability using a minimal 

amount of water 

-

  Trouble free design for safe and easy application 

-

  Available in different sizes and configurations to suit 

hazards requirements
