  • Sustainable Fire ProtectionThank you !www.fireflex.com Alberta IndustrialFire Chiefs

  • Information required for pricingTo determine foam type and nozzle spacingType of product involved, provide MSDS if availableHydrocarbon or Polar SolvantsTo establish the nozzle layoutDrawing or sketch of the area(s) to be protectedPlan view showing dimensions and ceiling heightElevation view required for 3D hazard such as transformerDimensions and location of obstructions that may affect discharge patternBeamsColumnsDuctsEquipment

  • Information required for pricingTo determine the system sizeIdentify the fire scenarioHow many zones could be actuated simultaneously

    Will multiple areas be protected by a single systemSingle zone system or multiple zone systemCould be a multiple zone system design for the largest zoneAdvantages to use a common foam tank and cylinder bank

    What is the minimum discharge time ?5 minutes for specific hazard applications such as transformers10 minutes for ceiling nozzle applications20 minutes recommended for aircraft hangars

  • To complete evaluationDetermine if minimum water supply is availableBased of minimum flow and pressure established during designDetermine if available water supply is sufficientMay require fire pump if pressure is not sufficientMay require stand alone water tank if flow is not sufficientFireflex can offer a pressure vessel type tank up to 2000 US-gallons

  • To complete evaluationDetermine actuation meansWhat type of fire detection is require ?There are no specific requirements for the ICAF SystemHeat, rate of rise or compensated, Protectowire, UV-IR, beam could be used to actuate the system Does the hazard area require explosion-proof or weather proof wiring and devices ?Are there any devices that need to be shut down prior to discharge ?

  • To complete evaluationIdentify possible location of system and maintenance areaIdentify preferred piping routeIdentify any obstructions to the piping routeRecord dimensions of possible mechanical roomWill a discharge test be done ?
