UL555 Certified Fire Smoke Damper model FSD-311 is a high performance combination fire smoke damper with Class I leakage with 1 1/2 hrs fire resistance rating. High strength airfoil blades ensure the lowest resistance to airflow in HVAC systems with velocities to 4000 fpm (20.3 m/s) and pressures to 8 in. wg (2 kPa). FSD-311 is available with high performance, fast acting spring return electric actuator / motor with fail-safe function and auxiliary switch for position indication. Actuator can be offered with 24V AC / DC or 230V AC power supply option.   Model FSD-311 may be installed vertically (with blades running horizontal) or horizontally and is rated for airflow and leakage in either direction. Model FSD-311 meets the requirements for fire dampers, smoke dampers and combination fire smoke dampers established by: National Fire Protection Association NFPA Standards 80, 90A, 92A, 92B, 101 & 105 IBC International Building Codes New York City (MEA listing #260-91-M) CSFM California State Fire Marshal Fire Damper Listing (#3225-0981:103) Leakage (Smoke) Damper Listing (#3230-0981:104) Key Features: UL 555 Fire Resistance Rating Fire Rating: 11⁄2 hours Dynamic Closure Rating: Actual ratings are size dependent Velocity: Up to 4,000 fpm (20.3 m/s) Pressure: Up to 8 in. wg (2 kPa) UL 555S Leakage Rating Leakage Class: I Operational Rating: Actual ratings are size dependent Velocity: Up to 4,000 fpm (20.3 m/s) Pressure: Up to 8 in. wg (2 kPa) Temperature: Up to 350°F (177°C) – depending upon the actuator Frame Material : Galvanized steel Frame Material Thickness : 16 ga.
