(LPCB).Tested to BS ISO 10294-1: 1996,BS EN 1366-2: 1999 andBS 476 Part 20: 1987 Fire TestStandards.Corrosion tested.New Self-Latching RemovableCassette, with even easier SingleHanded Reset.Stainless Steel folding curtain.Choice of 230 Volt A.C. or 24 VoltA.C. and D.C. remote electromagnet fail-safe releases oncassette type options only.

Fire/ShieldThe RangeThe Fire/Shield range of quality engineereddampers are suitable for air conditioningand ventilation systems requiring up to 4hour fire protection.These stainless steel bladed ActionairFire/Shield Dampers fail-safe closed andare supplied with the new innovative,even easier Single-Handed Reset SelfLatching Removable Release MechanismCassette, which permits single handed reset.Ordinary steel curtain fire dampers involvea complex pull and lift curtain openingoperation, further complicated by havingto hold the curtain in the fully open positionagainst the constant tension of closuresprings whilst attempting to reset orreplace the fusible link unsighted.ApplicationParametersFire/Shield Dampers are designed forapplication in normal dry filtered airsystems. If exposed to fresh air intakesand/or inclement conditions the dampershould be subject to a planned inspectionprogramme.Any specialists and/or aggressive applications(e.g. swimming pools) may invalidate ourwarranty, please refer to Actionair SalesOffice.Innovative cassette,CassetteCassette Details● Patented design.● Made of Polyphenylenesulphide(PPS) resin reinforced with 40%glass (GF-PPS).Blade FeaturesThe Type 1.4016 (430) Ferritic StainlessSteel folding blade curtain, providingmaximum strength, form a fire shield. Thewide profile blades maximise the damperfree area and ensure compact grouping tominimise blade stacking height.Optional blade construction Type 1.4401(316) Austenitic Stainless Steel.Side Seal GasketingStainless Steel side seal gasketingprovides constant pressure on bladeedges, minimising the spread of smokeand other products of combustion.Ordinary steel curtain fire dampers maynot have side seal gasketing.Stainless Steel Closure SpringsStainless Steel constant tension springsare fitted and positioned out of theairstream to close and latch the damper,regardless of vertical or horizontaloperation.Spigotted Casing FeaturesThe spigotted casing with continuouslywelded corners and spigot connections,makes these dampers suitable forinclusion into air distribution systems tothe test methods of Eurovent Class A, B& C and HVCA Ductwork specificationDW144.These galvanised casings are manufacturedwith either Square, Rectangular, Circularor Flat Oval duct connections.As an option, casings can be manufacturedin Type 1.4016 (430) Ferritic or Type1.4401 (316) Austenitic Stainless Steel.Ordinary steel curtain fire dampersfor low or medium velocity operation andhaving the blades and/or part of the casingframe in the airstream may not havecasings of continuous welded airtightconstruction.● Technically advanced engineeringpolymer.● PPS is stable at temperatures up to200 °C.● Cassette construction is of veryhigh strength and has excellentcreep and fatigue resistance.● Low smoke and toxic emissions infire conditions.● Halogen free● PPS has a very low moistureabsorption.● PPS is corrosion resistant.● The Cassette construction isenvironmentally friendly (recyclablematerial).● The new Cassette is retrofittable toexisting Fire/Shield Dampers (byuse of a simple optional adaptionbracket).● One Cassette to suit all dampermaterial options.2

Fire/ShieldExternal VisualBlade PositionIndicationAn external indicator is factory fitted to theaccess (cassette) side of the dampercasing giving visual indication of damperblade position.A spring steel actuator ensures automaticresetting of the external indicator in eitherhorizontal or vertical applications.The external indicator is especiallybeneficial at the system balancing andcommissioning stage eliminating thenecessity of internal duct inspection todetermine the fire damper open or closedposition.AccessoriesGalvanised Steel Installation Frames(as required by HVC 6/5/83 Rev.1 July1999.)Installation frames are delivered to site as acomplete assembly with the appropriateFire/Shield Damper fitted therein. The frameshall be installed centrally in the thickness ofa brick, blockwork or concrete surroundingwall or floor, or in the case of thick walls orfloors, so that the centre line of the frame isat least 50mm away from the nearest faceof the wall or floor in which the assembly ismounted. The four tabs (building tie)forming each fixing point shall provide apositive fixing into the structure. Multipleassembly dampers up to 1500 x 1500 or2000 x 1000 can be fitted into fullyassembled installation frames and deliveredas one piece. Dampers in excess of this sizewill be supplied in sections with theinstallation frame supplied in kit form. Adrawing and method statement will besupplied for the assembly to be fitted on site.The maximum size of kit form installationframes will be to accommodate a four sectionassembly.a. In brick or blockwork walls the tabs shallbe bent out and solidly built into the mortarjoints between the brick or blockwork.b. In the case of reinforced concrete wallsand floors, the tabs shall be bent out andtied with wire to the reinforcing bars whichwill be deliberately left protruding into theopening.The gap between the installation frameand builders work shall be backfilledwith mortar or concrete on both sides ofthe flange.Adjacent frame assemblies must beseparated by builders work of a minimumthickness of 225mm (between installationframe upstand flanges) unless approval hasbeen previously obtained from theappropriate Authority. For solutions belowthis dimension please refer to ActionairSales office.In no case shall the HEVAC/HVCA frameand damper assembly be held in positionmerely by the adjacent ductwork, and itshould be noted that in reinforced concretestructures (especially floors), it will not besufficient to only backfill between thedamper installation frame and thesurrounding opening with mortar or fineaggregate concrete mix without provisionfor tying in the frame to the surroundingreinforced concrete structure.Fluorescent Red DisplayIndicating damper blades in closedposition.Note: External visual blade positionindication is not available with specialfinished casings, certain multipleassemblies, miscellaneous Damperconfigurations and due to physical sizelimitations is not available below125mm dia. on Series 301 Dampers.Galvanised steel spacer sections locatedat each corner maintain clearancebetween frame and damper casing topermit the expansion of the latter in a firecondition.All Fire Damper installations requirerelevant Local Authority approval.Galvanised steel frame, the corners leftopen with predetermined clearance spaceto permit the expansion of the completeassembly in a fire condition. Pressed steelcorner brackets retain frame open cornersin such a manner that all corners maintaintheir integrity against the passage ofsmoke or flame between the frame and thedamper casing.Aluminium rivets fix the pressed steelcorner brackets to the frame and collapsein a fire situation to allow internal expansionof the installation frame.A binder containing certain approvedinstallation illustrations is available,please contact the Sales Office or visitour website, www. actionair.co.uk.Although the included methods havebeen tested and assessed, it isrecommend, that these, as with allinstallation methods must be confirmedwith Building Control / Local Authorityprior to manufacture. Actionair can alsoprovide applications of other proposedmethods of installation, please contactour Sales Office to discuss your specificrequirements. These again are theresponsibility of the client to ensure thatthese are acceptable to Building Control/ Local Authority before constructioncommences.4
