Smoke damp
18、ers are intended: a) To restrict the spread of smoke in HVAC systems that are designed to be automatically shut down in the event of a re, or b) To assist with the control of pressure differentials across smoke barriers when the HVAC system is part of an engineered smoke control system. 1.2 Dampers
19、covered by these requirements are evaluated for use as either: a) Smoke Dampers For use in HVAC systems where ducts pass through smoke barriers. b) Combination Fire and Smoke Dampers For locations in HVAC systems where a re damper and a smoke damper are required at a single location, or c) Corridor
20、Dampers For locations in HVAC Systems where air ducts penetrate or terminate at openings in the ceilings of interior corridors when permitted by authority having jurisdiction. 1.3 The smoke dampers covered by these requirements are intended for installation in accordance with the National Fire Prote
21、ction Association Standard for Installation of Air Conditioning and Ventilating Systems, NFPA 90A, the International Mechanical Code and the Uniform Mechanical Code. 1.4 Combination re and smoke dampers and corridor dampers shall also comply with the applicable requirements in the Standard for Fire
22、Dampers, UL 555. 2 General 2.1 Components 2.1.1 Except as indicated in 2.1.2, a component of a product covered by this standard shall comply with the requirements for that component. See Appendix A for a list of standards covering components generally used in the products covered by this standard. 2
23、.1.2 A component is not required to comply with a specic requirement that: a) Involves a feature or characteristic not required in the application of the component in the product covered by this standard, or b) Is superseded by a requirement in this standard. 2.1.3 A component shall be used in accor
24、dance with its rating established for the intended conditions of use. AUGUST 9, 2016 SMOKE DAMPERS - UL 555S 4UL COPYRIGHTED MATERIAL NOT AUTHORIZED FOR FURTHER REPRODUCTION OR DISTRIBUTION WITHOUT PERMISSION FROM UL 2.1.4 Specic components are incomplete in construction features or restricted in pe
25、rformance capabilities. Such components are intended for use only under limited conditions, such as certain temperatures not exceeding specied limits, and shall be used only under those specic conditions. 2.2 Units of measurement 2.2.1 Values stated without parentheses are the requirement. Values in
26、 parentheses are explanatory or approximate information. 2.3 Undated references 2.3.1 Any undated reference to a code or standard appearing in the requirements of this standard shall be interpreted as referring to the latest edition of that code or standard. 3 Glossary 3.1 For the purpose of this st
27、andard the following denitions apply. 3.2 CONTROLLED CLOSURE The closure of a damper by means of electric, pneumatic, hydraulic, or other similar device that inhibits the rate of closure. 3.3 DYNAMIC CLOSURE The closure of a re damper under conditions of airow and heat upon activation of the heat re
28、sponsive device. 3.4 HEATED AIR OPERATION The operation of a smoke damper by means of the actuator when the damper is subjected to a condition of airow and heat. 3.5 MULTIPLE SECTION DAMPER ASSEMBLY Two or more dampers assembled together to function as a single smoke damper, or corridor damper or co
29、mbination re and smoke damper. 3.6 NON-CONTROLLED CLOSURE The closure of a damper by means of spring operation, gravity or other similar device that does not inhibit the rate of closure. Non-controlled closure is also referred to as instantaneous closure, rapid closure or slam shut closure. 3.7 SAME
30、 DESIGN FAMILY Actuators composed of the same gear train and motor but incorporates a transformer, among other features, for different input voltages and has nominally the same force/torque output. 3.8 SMOKE CONTROL SYSTEM An engineered system that uses mechanical fans to produce airows and pressure
31、 differences across smoke barriers to limit (see Table 16.1, Leakage classications) and direct smoke movement. 3.9 VOLUME CONTROL DAMPER A re damper employing position devices that enable the re damper to remain in positions other than fully open or fully closed.
