They areintended for use where building codes call for thefire damper to also operate as a smoke damper.• U.L. 555 and U.L.C. S112 listed and labelled asa 1-1/2 hour fire damper.• U.L.and U.L.C. listed for vertical mounting.• U.L. 555S and U.L.C. S112.1 listed and labelledas a Leakage Class II rated Smoke Damper withairflow in both directions. Class II provides for amaximum leakage of 20 cfm per sq. ft. at 4.0 inchesstatic pressure. As we are constantly expanding ourU.L./U.L.C. listings, we suggest you contact thefactory for current information.• The snap disk is a reusable/resettable heatresponse device that can be reset after visualinspection of the damper. Also available withautomatic resettable/override release options:Model STO/R (single thermostat) or Model DTO/R(double thermostat) to provide the fire fighterwith complete discretionary control of smokefunctions during a fire/smoke emergency. (SeeSTO/R and DTO/R submittal drawings forcomplete details). Spring return type damper motorcontrolled by a smoke detector is recommended toprovide proper operation in the smoke mode.• Also available are options EFL (Electric FusibleLink) and PFV (Pneumatic Fusible Valve). Theseoptions provide quick and economical ways to checkdamper operations and also provide a SystematicClosure Control. Option PFV allows damperoperation without the need/cost for an E-P valveand electrical connection at the damper.Not recommended with blades running vertically. Suggested SpecificationCombination Fire/Smoke Dampers shall be Model: FSD-AF-FA-212 by NCA Manufacturing. Fire/Smoke Dampers shall bear the Underwriters' Laboratorieslabels for both Fire Dampers and Smoke Dampers. Each damper shall be UL/ULC qualified for mounting outside of the plane of the wall and have concealedactuator access, from grille side, to allow ‘through the grille’ access to actuator and controls. U.L. 555S rating shall be Class II with leakage not to exceed20 cfm per sq. ft.. at 4.0 inches static pressure for any size. Linkage shall be of the concealed type for maximum free area.Manufacturer’s RecommendationsAll moving parts of the damper must be inspected and cycled at intervals not greater than every twelve months or in accordance withthe latest edition of NFPA 80, 90A, 92A, local codes and the actuator manufacturer. In addition, the damper shall be inspected forcorrosion. Dry lubricants are recommended.Specifications are correct at time of printing. However, as part of our ‘continuous improvement program,’ we reserve the right to make further improvements without notice.© 2006 NCA Manufacturing6’’Grille By OthersThermalBlanket(Typ. 3 Sides)ActuatorCompartment1’’ FlangeFrontAccessCoverHeight6’’ Max.LISTINGSTATE OF CALIFORNIASTATEFIRES E R VM A R S H A L LIC ELISTED AND LABELLED BY:CLASSIFIEDU L RProject:Location:Architect:Engineer:Contractor:Address:P.O.
