28、ODUCTION OR DISTRIBUTION WITHOUT PERMISSION FROM UL INTRODUCTION 1 Scope 1.1 These requirements cover the construction and operation of xed condensed aerosol extinguishing system units inclusive of aerosol generating extinguishing system units and aerosol generating automatic extinguisher units inte
29、nded for total ooding applications when installed, inspected, tested, and maintained in accordance with the Standard for Fixed Aerosol Fire Extinguishing Systems, NFPA 2010. 1.2 Aerosol generating automatic extinguisher units do not have a manual means of operation, and are not intended: a) For use
30、as a general substitute for aerosol generating extinguishing system units; or b) For protection of re risks larger than those specied in the installation instructions for a single unit by using multiple units. 2 Components 2.1 Except as indicated in 2.2, a component of a product covered by this stan
31、dard shall comply with the requirements for that component. 2.2 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or characteristic not required in the application of the component in the product covered by this standard; or b) Is superseded by a requirement
32、 in this standard. 2.3 A component shall be used in accordance with its rating established for the intended conditions of use. 2.4 Specic components are incomplete in construction features or restricted in performance capabilities. Such components are intended for use only under limited conditions,
33、such as certain temperatures not exceeding specied limits, and shall be used only under those specic conditions.

34、its of Measurement 3.1 The metric unit shall be designated as the official unit for purposes of this standard. Where values of measurement are specied in both SI and English units, either unit is used. In cases of dispute, the metric unit shall be used. 4 Undated References 4.1 Any undated reference
35、 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. 5 Glossary 5.1 For the purpose of this standard, the following denitions apply. 5.2 ACTUATING MECHANISM A device whose automatic or manual operation
36、 results in the physical discharge of extinguishing agent. 5.3 AEROSOL EXTINGUISHING AGENT A re-extinguishing medium consisting of gaseous matter and nely divided solid particles generally having approximate diameters in the order of microns that is produced by a combustion process of an aerosol-for
37、ming compound. 5.4 AEROSOL EXTINGUISHING AGENT QUANTITY For re tests, the required mass of solid aerosol-forming compound to achieve the extinguishing application density (for extinguishing system units) or design application density (for automatic extinguisher units) within the protected volume and
38、 within the specied discharge time. 5.5 AEROSOL-FORMING COMPOUND A solid mixture of oxidant(s) and combustible component(s) included within a condensed aerosol generator that produces an aerosol extinguishing agent during combustion. 5.6 AUTOMATIC EXTINGUISHER UNIT A condensed aerosol generator with
39、 mounting bracket that: a) Has no manual method of actuation; b) Has an automatic thermal method of actuation; c) Is intended for use in normally unoccupied spaces; and d) Is limited to a single protected area as specied in 1.2. 5.7 CASING The external surface(s) of a condensed aerosol generator, ex
40、cluding the surface(s) containing the discharge port(s). 5.8 CONDENSED AEROSOL GENERATOR (AEROSOL GENERATOR) A normally non-pressurized device incorporating an aerosol-forming compound that, when pyrotechnically actuated, produces an aerosol extinguishing agent that ows through a cooling mechanism w
41、ithin the device prior to exiting through the discharge port(s). 5.9 COOLANT A heat-absorbing process or medium included within a condensed aerosol generator that effectively reduces the temperature of an aerosol extinguishing agent prior to exiting through the discharge port(s).

43、afety factor, required for total ooding system design purposes. 5.11 DISCHARGE PORT The opening(s) on a condensed aerosol generator from which aerosol extinguishing agent exits providing uniform distribution: a) Over a specic area or b) Within a specic volume or c) Both. 5.12 DISCHARGE TIME The time
44、 interval between condensed aerosol generator activation and the end of aerosol extinguishing agent exiting from the discharge ports. 5.13 EXTINGUISHING APPLICATION DENSITY The minimum mass of a specic aerosol-forming compound per cubic meter of enclosure volume, excluding a safety factor, required
45、to extinguish re in total ooding applications involving a particular fuel under dened experimental conditions. 5.14 EXTINGUISHING SYSTEM UNIT One or more condensed aerosol generators with mounting brackets, actuation mechanisms, and other accessory equipment (as applicable) designed for automatic an

47、extinguishing agent is required to maintain an even distribution throughout the protected volume in an amount sufficient to prevent re-ignition. 5.17 IGNITION DEVICE Device that initiates the pyrotechnic reaction of the solid aerosol-forming compound. 5.18 METHOD OF ACTUATION, AUTOMATIC A means of a
48、ctuation that results in extinguishing agent discharge without the necessity of human intervention, such as a thermal actuating mechanism. 5.19 METHOD OF ACTUATION, MANUAL A means of actuation that results in extinguishing agent discharge with the necessity of human intervention, either mechanically
