Specificatons
True Round 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 & 105.
Damper shall be constructed of 20 ga. (1mm) 304 stainless steel
frame; blades constructed of double skin 304 stainless steel round
style blades; silicone rubber blade seals; stainless steel linkage;
½ in. stainless steel axles; stainless steel bearings. Damper is
provided with one retainer plate.
Dampers shall be tested, rated and labeled in accordance with the
latest edition of UL standards 555 and 555S. Dampers shall have a
UL555 fire rating of 1½ 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 UL555.
The heat responsive device shall have a temperature rating of
(specifier select one or the following) 165°F (74°C), 212°F (100°C),
286°F (141°C), or 350°F (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 dampers installed location and a
dynamic closure pressure rating of 4 in. wg (1kPa). All UL555
and UL555S dynamic closure and leakage ratings shall be
qualified for airflow and pressure in either direction through
the damper. UL ratings shall allow for mounting damper
vertically or horizontally.
Dampers shall have a UL555S leakage rating of Class
II and a temperature rating of 250°F (121°C) minimum.
Dampers shall have a UL555S operational airflow rating

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 120 or 24 volt operation and
pneumatic type for 25 psi minimum (30 psi maximum)
operation. Manufacturer’s submittal data shall indicate
actuator space requirements around the damper.
The Damper manufacturer’s submittal data shall certify
all air performance pressure drop data is tested 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.
