ICAF - Integrated Compressed Air Foam SystemGeneral SectionPage 1 of 10General1. Applicable StandardsDesign and installation of CAF (Compressed Air Foam)systems are covered by NFPA 11, via TIA (Tentative InterimAmendment) #05-1. Complete design and installation shallbe prepared in full accordance with FireFlex's Design Manual(FM-090M-0-01).Working plans shall be prepared only by persons fullyexperienced and qualified in the design of fixed CompressedAir Foam systems. Working plans shall be reviewed byFireFlex's engineering department prior to installation. Nodeviation from these documents shall be made without priorpermission from FireFlex Systems Inc.Before the installation, the contractor installing the systemshall 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 SprinklerSystems;- NFPA 72, National Fire Alarm Code;- Applicable Local & State Building Codes;- Any additional requirements of the Local AuthorityHaving Jurisdiction.2. Listings and ApprovalsIn addition to being fabricated under strict ISO-9001manufacturing and quality control procedures, your ICAFSystem has also been tested and approved by FactoryMutual Research under the heading: "IntegratedCompressed Air Foam Extinguishing System for Fixed PipingNetworks, Class 5135" when installed with specificcomponents.CAUTION ! Any unauthorized modification or additionmade on-site to a factory built Approved system will voidthis Approval. Such modifications or additions may alsovoid the system's warranty as well. Consult FireFlexSystems Inc. Engineering Department before proceedingwith any such modifications or additions.3. EnvironmentAll ICAF Systems shall be installed in a dry and cleanlocation. Verify that all equipment is properly heated andprotected to prevent freezing and physical damage.The system and its components must be kept free of foreignmatter, freezing conditions, corrosive atmospheres,contaminated water supplies, and any condition that couldimpair its operation or damage the components.The frequency of the inspections and maintenance will varydepending on these environmental conditions. The owner isresponsible for maintaining the fire protection system anddevices in proper operating condition.4. General DescriptionCompressed Air Foam (CAF) is formed by combining airunder pressure, water and foam concentrate in the rightproportions, and then sending it through piping for distributionon the protected area.Integrated Compressed Air Foam (ICAF) Systems for fixedpiping networks consist of a complete system including thecompressed air supply equipment, the water control valve,the foam tank and a mixing chamber, all pre-assembled, prewiredand factory tested. All electrical and mechanicalcomponents of the system are contained in single or multipleunits and ready to be connected to a fixed piping network.The CAF is carried using standard piping network as used forconventional sprinkler or foam systems. To distribute theCAF over the hazard area, nozzles specially developed forCAF are used. These nozzles are offered in different typesfor various applications. The nozzles are rotary type andinsure uniform CAF distribution over the protected area.A detection network is used in parallel with the open typenozzles. This network may be pneumatic or electric and maybe actuated by manual, fixed temperature, rate-of-risetemperature, smoke or other means. When the detectionsystem operates, it gives an alarm and activates the ICAFSystem. Because ICAF Systems are often used in extrahazardoccupancies, electrical and pneumatic detectionsystems are by far the most common.The connections required for installation are the water supplyinlet, the compressed air and the foam concentrateinterconnection with the system trim, CAF discharge outlet,open type main drain, electrical connections with air cylinderspressure transducer and the electrical detection and alarmconnections. The discharge outlet is connected to a fixedpiping system of open nozzles.The ICAF system is supervised in order to monitor itsintegrity. The electrical detectors and associated wiring arealso supervised.Note: Each ICAF System mixing chamber is identified withits unique Serial Number. This number is located on asticker on the mixing chamber inside the cabinet and isused to maintain a record in our computerized data base.Have these Serial Numbers handy when calling forinformation on your unit (format is MIX-XXXXX).5. FeaturesYour ICAF System is superior to many other productsavailable on the market now and has been manufactured bythe company that has introduced and developed the conceptof integrated fire protection systems on the market.Main features are:- Very efficient suppression capability using a minimalamount of water- Trouble free design for safe and easy application- Available in different sizes and configuration to suithazards requirementsFM-0723-0-07 C

The system piping is empty until the system isactivated by a pneumatic, electric or manual release system.Single zone configuration can be used to protect smallerhazards whereas multiple zones and multiple mixingchambers configurations can be used to protect largerhazards or a combination of smaller independent hazards.System requires a reliable and automatic water supply. Airsupply is provided by compressed air cylinders mounted on askid and includes an air pressure regulator. Foamconcentrate is contained inside a stainless steel tank. Uponsystem activation, the foam concentrate tank is pressurizedand water, air and foam concentrate are injected and mixedtogether inside a mixing chamber. Compressed Air Foam isthen generated and moves inside the piping network towardthe distribution nozzles.ICAF Systems trims including water, air and foam controls,CAF mixing chamber and release system are factoryassembled in cabinets and available in self-contained,remote controlled and extension unit configurations to suitproject's requirements. A description of the available unitsfollows: Self-Contained UnitThis unit includes all the mechanical controls & trims,CAF mixing chamber(s) and is provided with the ARC-1releasing control panel.Components size and quantity of mixing chambers aredetermined by the system's flow and configurationrequired to supply the nozzles in the hazard(s). Remote Controlled UnitThis unit is used when an additional zone is required tobe protected by the same system. This unit includes allthe mechanical controls, trims and CAF mixingchamber(s) and is provided with a field wiring junction boxin lieu of the releasing control panel enclosure. Thisshould then be connected to the control panel of the selfcontainedunit.Components size and quantity of mixing chambers aredetermined by the system's flow and configurationrequired to supply the nozzles in the hazards. Extension UnitThis unit is used when additional mixing chambers arerequired to supply a single zone with a larger amount ofnozzles. This unit includes the CAF mixing chamber(s)without any controls or releasing control panel. It shouldbe used in parallel with a self-contained unit or a remotecontrolled unit.Water SupplyCAF technology offers an important reduction in the watersupply requirements compared to standard sprinklers orfoam systems. The system can operate with a waterpressure in the range of 50 to 175 psi (345 to 1206 kPa).The ICAF System is dependable, automatic and capable ofproviding the required flow and pressure for the requiredduration.ICAF System uses pneumatically actuated globe valves for¾" (20 mm) diameter or Listed fire protection flow controlvalves 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: ¾" (20 mm) 1½" (40 mm) 2" (50 mm) 3" (80 mm)When water pumps are required for system operation, theyshall 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 inaccordance with NFPA 24, Standard for the Installation ofPrivate Fire Service Mains and their Appurtenances. Astrainer shall be provided on water supplies containing solidslikely to clog orifices. Such strainers shall be provided with acleanout port and shall be arranged to facilitate inspection,maintenance and replacement.Air SupplyCAF is 90% compressed air. Air is provided by cylindersbank as described in the Air Supply Section.The connection is used to supply compressed air betweenthe cylinders bank and the ICAF System. The piping isfactory prepared according to installation arrangement and issupplied with the system. The system can be configured for: Single air interconnection line (circled item 4). Multiple air interconnection lines (circled item 4).FM-0723-0-07 C
