Fire Damper for Circular Ducts - Halton

FunctionThe FDC is a circular fire damper of fire resistanceclass EIS 30 to EIS 120, which prevents fire andsmoke from spreading in ventilation ducts. The firedamper is equipped with either a motorised actuatoror manual actuation arrangement. Both actuatorshave a visual position indicator. If the power in themotorised actuator system is switched off, the bladecloses automatically.Europe and Russia models:In both actuator options, a fuse reacts to a rise intemperature, causing a spring-return blade to close.The motorised fire damper is delivered complete witha spring-return actuator and a fuse that is activated at72 ºC.Pressure drop and sound dataSound power level Lw, in in each ocatve band iscomputed bu adding the corresponding correctionfactor, Kok, to the sound pressure level in theselection chart according to the following equation.Lw = LpA + KokThe corresponding factor Kok is the average of theFDC operating area.20/FDC/3500/0907/ENSweden model:The electrical motor option is without thermal fuseand shall be connected to an automatic alarm system.The fire damper is made of fireproof materials. Oncethe fire damper has closed, the double sealing closesthe duct tightly, effectively preventing the spreadingof flue gases in the ventilation ductwork. The flexibleseal of the double sealing system operates at lowertemperatures, while the graphite mass seal expandsto insulate the system at temperatures above 150 ºC.The FDC fire damper can be connected to the MSHcontrol and testing system for fire dampers. TheMSH unit enables the use of smoke detectors in theductwork or rooms. The FDC fire damper also canbe connected to other common building automationsystems.f / [Hz] 125 250 500 1k 2k 4k 8kkok 13 7 1 -5 -7 -14 -27l / dB +/- 2 +/- 2 +/- 2 +/- 2 +/- 2 +/- 2 +/- 2FDC - Fire Damper for Circular Ducts127

InstallationInstallation on concrete and masonry wallsWhen the fire damper is installed on concreteand masonry walls and ceilings between firecompartments, the blade shaft is always horizontal.An opening is always left in the separating elementfor the fire damper, and the product subsequently isgrouted into this.To make installation easier, all products come withan installation flange, which is used to fasten the firedamper to the concrete surface with screws beforegrouting.During installation, the fire damper and actuator mustbe protected with, e.g., a plastic cover.The correct operation of the fire damper must beensured before and after grouting.When the damper is installed on concrete andmasonry walls or ceilings, the size of the installationhole is D+50 mm.Installation on lightweight plasterboard wallsWhen the fire damper is installed on lightweightplasterboard walls between fire compartments,an opening for the fire damper must be left in theplasterboard in which the installation frame (includedin the delivery) is first mounted.The blade shaft must always be horizontal.To make installation easier, the fire damper comeswith an installation flange, which is used to fasten thefire damper to, e.g., the steel frame of the panel wall.The space between the fire damper and theinstallation frame is filled with fire prevention mastic.During installation, the fire damper and actuator mustbe protected with, e.g., a plastic cover.The correct operation of the fire damper must beensured after application of the fire prevention mastic.For lightweight walls, the size of the installation holevaries with the specific product; consult the section‘Documents / Installation Instructions’ for the size ofthe installation holes.20/FDC/3500/0907/ENDetailed installation instructions, as well as aninstaller’s installation certificate form, are suppliedwith each product.
