SUGGESTED SPECIFICATION:
Provide and install, as shown on plans and/or schedules, multi-blade Dynamic Fire Dampers, as manufactured by Nailor
Industries, meeting or exceeding the following criteria: Frame shall be constructed of 16 ga. (1.6) galvanized steel hat channel
with mitered corners reinforced with die-formed corner gussets for strength. Blades shall be 14 ga. (2.0) equivalent galvanized
steel formed double skin, airfoil design, on 5 1/2" (140) centers. Dampers shall be of opposed blade configuration with an
interlocking blade design that provides complete flame and smoke seal under fire conditions at an elevated temperature of 2000°F
(1093°C) when in closed position. Blade axles shall be plated steel, double bolted at each end of blade to provide positive locking
connection. Hex or square friction-fit, or press-fit axles are not acceptable. Bearings shall be self-lubricating oilite bronze type.
Blade linkage shall be zero-maintenance, concealed in frame, out of airstream.
Fire dampers shall meet the requirements of NFPA 90A and shall be manufactured, tested and labeled in accordance with UL 555
Safety Standard for Fire Dampers – Sixth Edition, June 1999, including Dynamic Closure Test. Dampers shall be classified for
dynamic closure against an airflow velocity of 2000 fpm (10.16 m/s) or 3000 fpm (15.24 m/s) (specifier select one) at 4" w.g.
(1 kPa) static pressure differential (across closed damper).
Each fire damper shall bear a UL 1 1/2 hour or 3 hour (specifier select one) fire resistance rating label, in addition to label
verifying the airflow and closure pressure ratings as established by the Dynamic Closure Test. Each fire damper shall also be
marked with the words "For use in dynamic systems". Dampers marked "For use in static systems only" are not acceptable.
Each fire damper shall be complete with a (specifier select one) 165°F (74°C) or 212°F (100°C) UL Listed fusible link that will
cause the damper to close and lock in closed position by means of an over center/knee lock linkage for assured closure. Fire
dampers shall each include a steel sleeve of appropriate length/gauge as field verified by contractor, and retaining angles,
supplied by damper manufacturer to ensure proper installation in accordance with damper manufacturer's instructions. Each
damper shall be supplied with an internal manual quadrant(s) for setting and locking of blades in desired position. Contractor shall
provide and install an access door at each fire damper, of appropriate size to allow for inspection, testing and fusible link
replacement. Information submitted for approval shall include independent pressure drop data and confirmation of UL
qualifications in addition to manufacturer's installation instructions. Each shipment of fire dampers shall include same installation
instructions. Dynamic rated fire dampers shall be Nailor Industries Model Series D1200 (1 1/2 hour label) or Model Series D1200-
3 (3 hour label), as indicated on plans.
