26、GENT EXTINGUISHING SYSTEM UNITS - UL 2166 5UL COPYRIGHTED MATERIAL NOT AUTHORIZED FOR FURTHER REPRODUCTION OR DISTRIBUTION WITHOUT PERMISSION FROM UL INTRODUCTION 1 Scope 1.1 These requirements cover the construction and operation of halocarbon clean agent re extinguishing system units intended to b

27、e installed, inspected, tested, and maintained in accordance with the Standard on Clean Agent Fire Extinguishing Systems, NFPA 2001. 1.2 These requirements also cover halocarbon clean agent automatic extinguisher units that do not have a manual means of operation, and are intended to be used in acco

28、rdance with the manufacturers installation instructions. Automatic extinguisher units are not intended: a) For use as a general substitute for pre-engineered or engineered clean agent extinguishing system units; or b) For protection of re risks larger than those specied in the manufacturers instruct

29、ions for a single unit by using multiple units. 2 General 2.1 Values stated without parentheses are the requirement. Values in parentheses are explanatory or approximate information. 2.2 Where these requirements reference extinguishing system unit, the requirements also apply to automatic extinguish

30、er units unless specically noted otherwise. 3 Glossary 3.1 For the purpose of these requirements, the following denitions apply. 3.2 AGENT TIME IMBALANCE A situation in which the start of agent discharge at a nozzle occurs after agent discharge has been completed at any other nozzle in the system. 3

31、.3 AUTOMATIC EXTINGUISHER UNIT A unit that has no manual means of actuation and discharges extinguishing agent upon thermal actuation, is intended for use in normally unoccupied space, and is limited to a single protected area per 1.2. 3.4 CLEAN AGENT Electrically nonconducting, volatile, or gaseous

32、 re extinguishant that does not leave a residue upon evaporation. The word agent as used in this document shall mean clean agent unless otherwise indicated. 3.5 CYLINDER/VALVE ASSEMBLY A container that incorporates a valve and which provides storage of the extinguishing agent and expellant (when app

33、licable) until the valve is actuated. When actuated, the valve releases the agent into the distribution network of the extinguishing system. 3.6 DISCHARGE NOZZLE A device that is used to uniformly distribute the extinguishing agent: a) Over a specic area; or b) Within a specic volume; or both.

34、T 29, 2012 HALOCARBON CLEAN AGENT EXTINGUISHING SYSTEM UNITS - UL 2166 6UL COPYRIGHTED MATERIAL NOT AUTHORIZED FOR FURTHER REPRODUCTION OR DISTRIBUTION WITHOUT PERMISSION FROM UL 3.7 DISCHARGE TIME The time required to discharge from the nozzle 95 percent of the agent mass at 70F (21C). For some hal

35、ocarbon agents, it is the time interval between the rst appearance of liquid at the nozzle and the time at which the discharge becomes predominantly gaseous. 3.8 DISCHARGE TIME, MAXIMUM The longest discharge time specied by the manufacturer; but, not greater than 10 seconds for Class A hazards or 10

36、 seconds for Class B hazards. 3.9 ENGINEERED SYSTEM A system that requires individual calculation and design, in accordance with the extinguishing system unit manufacturers instructions, to determine the ow rates, nozzle pressures, quantities of extinguishing agent, and number and types of nozzles f

37、or effective extinguishing agent distribution and re coverage. 3.10 EXPELLANT GAS An inert gas used to facilitate the discharge of a superpressurized extinguishing agent at low temperatures. 3.11 EXTINGUISHING SYSTEM UNIT Identied components that are assembled into system for the discharge of an ext

38、inguishing agent through xed piping and nozzles for the purpose of extinguishing res. 3.12 HALOCARBON CLEAN AGENT A clean agent that contains as primary components one or more organic compounds containing one or more of the elements uorine, chlorine, bromine, or iodine. Examples are: hydrouorocarbon

39、s (HFCs); hydrochlorouorocarbons (HCFCs); peruorocarbons (PFCs or FCs); and uoroiodocarbons (FICs). 3.13 MANUAL MEANS OF ACTUATION A means of system actuation in which the system operator initiates system discharge, either mechanically or electrically. 3.14 MASTER VALVE A discharge valve that upon a

40、utomatic or manual actuation operates other valves or devices in an extinguishing system. 3.15 MINIMUM DESIGN NOZZLE PRESSURE Typically, the minimum average pressure for a nozzle present during system discharge. 3.16 OPERABLE PRESSURE RANGE The pressure range corresponding to the pressures in the st

41、orage container at the specied minimum and maximum temperatures for which the extinguishing system unit is intended to be operable. 3.17 OPERATING PRESSURE The pressure in a fully charged storage container at 70F (21C). 3.18 PRE-ENGINEERED SYSTEM A system that is tested in accordance with the limita

42、tions prescribed by the manufacturer for maximum and minimum pipe lengths, accessories, number of ttings, number and types of nozzles and nozzle placement, maximum areas, volumes, or both areas and volumes of protection. 3.19 PROOF TEST PRESSURE The factory test pressure of each cylinder used to eva

43、luate cylinder leakage and construction integrity. For Department of Transportation (DOT) approved cylinders, the factory test pressure is specied in the appropriate DOT specication. For ASME vessels, the factory test pressure is specied in Section VIII, Pressure Vessels, of the ANSI/ASME Boiler and

44、 Pressure Vessel Code. For non-DOT cylinders and non-ASME cylinders, the factory test pressure is three times the cylinder operating pressure at 70F (21C).

45、DISTRIBUTION WITHOUT PERMISSION FROM UL 3.20 SELECTOR (DIRECTIONAL) VALVE A device that is installed in the piping of an extinguishing system and that directs the ow of extinguishing agent to the appropriate protected volume. This valve is used only when more than one volume is being protected by a

46、single extinguishing system. 3.21 TOTAL FLOODING SYSTEM A system consisting of a supply of halocarbon clean agent arranged to discharge the extinguishing agent into the intended protected volume and to ll that volume to an effective extinguishing agent concentration. 4 Components 4.1 Except as indic

47、ated in 4.2, a component of a product covered by this standard shall comply with the requirements for that component. 4.2 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 cove

48、red by this standard, or b) Is superseded by a requirement in this standard. 4.3 A component shall be used in accordance with its rating established for the intended conditions of use. 4.4 Specic components are incomplete in construction features or restricted in performance capabilities. Such compo

49、nents 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. 5 Design Manual 5.1 An engineered clean agent extinguishing system unit shall have a design manual that references the limitations determined by the calculation method and includes at least the following items: a) A description of the general principles utiliz
