Model SMD-201 meets the requirements for smoke
dampers established by:
National Fire Protection Association
NFPA Standards 92A, 92B, 101 & 105
IBC International Building Codes
New York City (MEA listing #260-91-M)
CSFM California State Fire Marshal
Leakage (Smoke) Damper Listing (#3230-0981:104)
Application
Model SMD-201 is a leakage rated smoke damper with 3V style
blades. The SMD-201 has been qualified to 2,000 fpm (10.2 m/s) and
4 in. wg (1 kPa) for operational closure in emergency smoke control
situations. Model SMD-201 may be installed vertically (with blades run-
ning horizontally) or horizontally and is rated for airflow and leakage in
either direction.
Ratings
Leakage: UL 555S leakage class I
(to 6 in. wg [1.5 kPa] ).Leakage rated
in both directions
Pressure: 4 in. wg (1 kPa) - differential pressure.
Consult factory for sizes available in
6 in. wg (1.5 kPa).
Velocity: Operational rated to 2000 fpm
(10.2 m/s). Rating is for airflow in
either direction through damper.
Temperature: 350°F (177°C) depending on the
actuator
Standard Construction
Frame: 5 in. x 1 in. (127mm x 25mm)
galvanized steel hat channel with
reinforced corners. A low profile
head and sill are used on sizes less
than 17 in. (432mm) high to maximize
free area and performance.
Blades: 16 ga. (1.5mm) galvanized steel,
reinforced with 3 longitudinal
structurally designed vee’s.
Seals: Flexible stainless steel jamb seals.
Extruded silicone rubber blade seals
Linkage: Concealed in jamb.
Axles:
1
⁄2 in. (13mm) dia. plated steel
Bearings: Bronze sleeve type
