Damper Sleeve Dimensional Data
The drawings below and corresponding table show the position of the FSD-M211 damper when mounted in a factory sleeve. 
The standard mounting locations provide enough space for the mounting of actuators, controls and allow space for installation 
of retaining angles and duct connections.

Specifications
Combination  Fire  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 the latest edition of NFPA 
80, 90A, 92A, 92B, 101, and 105.
Dampers  shall  be  tested ,  rated  and  labeled  in  accordance  with  the  latest 
edition of UL Standards 555 and 555S. Dampers shall have a UL 555 fire rating 
of  11⁄2  hours.  Each  damper  shall  be  equipped  with  a  heat  responsive  device 
which  has  been  tested  and  approved  for  use  with  the  damper  assembly  in 
accordance with UL 555. The heat responsive device shall have a temperature 
rating of (specifier select one of the following) 74°C, 100°C, or 177°C. Dampers 
shall  be  UL  labeled  for  use  in  dynamic  systems.  The  damper  shall  have  a 
dynamic  closure  airflow  rating  equal  to  or  greater  than  the  airflow  at  the 
damper’s installed location and a dynamic closure pressure rating of 1 kPa.
Dampers  shall  have  a  UL  555S  Leakage  rating  of  Class  I  and  a  Temperature 
rating of 177°C. Dampers shall have a UL 555S operational airflow rating equal 
to or greater than the airflow at its installed location and an operational pressure 
rating of 996 Pa. Damper actuators shall be factory mounted and qualified for 
use  with  the  damper  in  accordance  with  UL  555S.  Damper  actuators  shall 
be  (specifier  select  one  of  the  following)  electric  type  for  120  (24  or  230)  volt 
operation or pneumatic type for 25 psi minimum (30 psi maximum) operation.  
Manufacturers  submittal  data  shall  indicate  actuator  space  requirements 
around the damper.
All  UL  555  and  555S  Dynamic  Closure  Ratings,  Operational  Ratings  and 
Leakage  Ratings  shall  be  qualified  for  airflow  and  pressure  in  either  direction 
through the damper. UL ratings shall allow for mounting damper vertically (with 
blades running horizontal) or horizontally.
The  Damper  Manufacturers  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.  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 blades shall be 1.5mm galvanized steel 3V type 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 13mm are unacceptable).
Damper  frames  shall  be  galvanized  steel  formed  into  a  structural  hat  channel 
shape  with  reinforced  corners.  Bearings  shall  be  sintered  bronze  sleeve  type 
rotating in extruded holes in the damper frame. Jamb seals shall be stainless 
steel compression type.
Basis of design is Greenheck Model FSD-M211.
