Model SMD-202  
Smoke Dampers  
Steel 3V Blades  
Application  
UL 555S Leakage Class II  
Model SMD-202 is a leakage rated smoke damper with 3V style  
blades. The SMD-202 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-202 may be installed vertically (with blades  
running horizontally) or horizontally and is rated for airflow and leakage  
in either direction.  
Model SMD-202 meets the requirements for smoke  
dampers established by:  
National Fire Protection Association

Application Data  
Damper Sleeve Dimensional Data  
The drawings below and corresponding table show the position of the SMD-202 damper when mounted in a factory sleeve.  
The standard mounting locations provide enough space for the mounting of actuators, controls and allow space for installa-  
tion of retaining angles and duct connections.  
The standard location of a damper mounted in a factory sleeve ("A" dimension) is shown below. The damper can be posi-  
tioned at other locations within a range of 6 in. (152mm) to 12 in. (305mm) for the "A" dimension.

Space Envelopes  
Externally mounted actuators always require space out-  
side of the damper sleeve. The “S” dimension illustrates  
the clearance required for various available actuators.  
On dampers less than 18 in. (457mm) high, actuators may  
also require clearances above and/or below the sleeve.  
“B” and “T” dimensions are worst case clearance require-  
ments for some dampers less than 18 in. (457mm) high.  
All damper sizes under 18 in. (457mm) high do not require  
these worst case clearances. If space availability above  
or below the damper sleeve is limited, each damper size  
should be individually evaluated.

Specifications  
Smoke Dampers meeting the following specifications shall be  
furnished and installed where shown on plans and/or as described  
in schedules. Dampers shall meet the requirements of NFPA 92A,  
92B, 101 & 105 and further shall be tested, rated and labeled in  
accordance with the latest edition of UL Standards 555S. Dampers  
shall have a low leakage design qualified to UL555S Leakage Class II.  
shall be silicone rubber designed to inflate and provide a tighter seal  
against leakage as pressure on either side of the damper increases.  
Jamb seals shall be stainless steel compression type. Blades shall be  
completely symmetrical relative to their axle pivot point, presenting  
identical resistance to airflow in either direction or pressure on either  
side of the damper.  
Each damper/actuator combination shall have a UL555S elevated  
temperature rating of 250°F (121°C) minimum and shall be  
operational at maximum design air flow at its installed location. Each  
damper shall be supplied with an appropriate actuator installed by  
the damper manufacturer at the time of damper fabrication. Damper  
actuator shall be (specifier select one of the following) electric  
type for 120 (24 or 230) Volt operation or pneumatic type for 25 psi

performance pressure drop data is licensed in accordance with the  
AMCA Certified Ratings Program for Test Figures 5.2, 5.3, and 5.5.  
Damper air performance data shall be developed in accordance with  
the latest edition of AMCA Standard 500-D. Dampers shall be labeled  
with the AMCA Air Performance Seal.  
Damper must be rated for mounting vertically (with blades running  
horizontal) or horizontally and be UL 555S rated for leakage and  
airflow in either direction through the damper.  
Damper blades shall be 16 ga. (1.5mm) galvanized steel 3V type with  
three longitudinal grooves for reinforcement. Damper frame shall
