Damper Sideplate and Sleeve Dimensional Data
The drawings above and below illustrate the factory standard sideplate and sleeve mountings for the SMD-M201. The standard
"A" dimensions listed in the table provide adequate space for the mounting of actuators and controls.
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 92A, 92B, 101 & 105.
Dampers shall be tested, rated and labeled in accordance with the
latest edition of UL Standard 555S. 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 121ºC. 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 20 psi or 25 psi minimum
operation (depending on actuator). Manufacturers submittal data
shall indicate actuator space requirements around the damper.
All UL 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 SMD-M201.
