Model SSSMD-201  
Smoke Dampers  
Stainless Steel 3V Blade  
UL 555S Leakage Class I  
Model SSSMD-201 meets the requirements for smoke  
dampers established by:  
National Fire Protection Association  
NFPA Standards 92A, 92B, 101 & 105  
Application  
Model SSSMD-201 is a 304 stainless steel leakage rated smoke  
damper with 3V style blades. The SSSMD-201 has been qualified to  
2000 fpm (10.2 m/s) and 4 in. wg (1 kPa) for operational closure in  
emergency smoke control situations. Model SSSMD-201 may be  
installed vertically (with blades running horizontally) or horizontally  
and is rated for airflow and leakage in either direction.

Space Envelopes Required for  
Actuators and Accessories  
Externally mounted actuators always require space outside  
of the damper sideplate or 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  
sideplate or sleeve. “B” and “T” dimensions are worst case  
clearance requirements 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.

in schedules. Dampers shall meet the requirements of NFPA 92A,  
92B, 101 and 105 and further shall be tested, rated and labeled in  
accordance with the latest edition of UL Standards 555S. Dampers  
shall be UL labeled for use in dynamic systems.  
with three longitudinal grooves for reinforcement. Blades shall be  
completely symmetrical relative to their axle pivot point, presenting  
identical resistance to airflow and operation in either direction  
through the damper (blades that are non-symmetrical relative to  
their axle pivot point or utilize blade stops larger than 0.5 in. are  
unacceptable).  
Dampers shall have a UL555S leakage rating of Class I and a  
temperature rating of 250ºF (121ºC) minimum. Dampers shall have a  
UL555S operational airflow rating equal to or greater than the airflow  
at its installed location and an operational pressure rating of 4 in. wg  
(1 kPa). Damper actuators shall be factory mounted and qualified for  
use with the damper in accordance with UL555S. Damper actuators  
shall be (specifier select one of the following) electric type for 120V,  
24V, 230 volt operation or pneumatic type for 25 psi minimum (30 psi  
maximum) operation. Manufacturer’s submittal data shall indicate  
actuator space requirements around the damper.  
Damper frames shall be 16 ga. (1.5mm) 304 stainless steel formed  
into a structural hat channel shape with reinforced corners. Bearings  
shall be stainless steel type rotating in extruded holes in the damper  
frame. Jamb seals shall be stainless steel compression type.  
The Damper manufacturer’s submittal data shall certify all air  
performance pressure drop data is licensed in accordance with the  
AMCA certified ratings program for test figures 5.2, 5.3, and 5.5.
