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.
