Dampers shall meet the requirements of the latest edition of NFPA 80, 90A, 92, 92A, 101 & 105. Damper shall be constructed of 20 ga. (1mm) 316 stainless steel frame; blades constructed of double skin 316 stainless steel round style blades; silicone rubber blade seals; . in. 316 stainless steel axles; 316 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 UL 555 fire damper of 1 1/2 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 UL555. The heat responsive device shall have a temperature rating of (specifier select one of the following) 165. F (74.C), 212. F (100.C), 286. F (141.C) , or 350. F (177.C). 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) DUCT CONNECTION AREA electric type for 120 (or 24) 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. Dampers shall have a UL555S leakage rating of Class I and a temperature rating of 250.F (121°C) minimum. Dampers shall have a UL555S operational airflow equal to or greater than the airflow at its installed location and an operational pressure rating of 4 in. wg (1 kPa). All UL555 and UL555S dynamic closure 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 or horizontally. 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.
