38、de speechcommunication and distinctive sounds in conjunction with fire protective signaling systems for indoorlocation in accordance with the following standards:a) National Electrical Code, NFPA 70.b) National Fire Alarm Code, NFPA 72.1.2 These requirements do not cover amplifiers for use in hazard
39、ous locations, as defined in the NationalElectrical Code, NFPA 70.1.3 These requirements do not cover commercial equipment for institutional and industrial use or theaterequipment. Commercial sound equipment is covered by the Standard for Commercial Audio Equipment,UL 813.1.4 These requirements do n
40、ot cover signal generating or processing equipment, such as tonegenerators, tape decks, microphones, and the like.1.5 These requirements do not include determination of compliance with regulations of the FederalCommunications Commission (FCC). Should products covered by these requirements be require
41、d tocomply with FCC regulations, a report of verification from the manufacturer is required as evidence ofsuch compliance.1.6 A product that contains features, characteristics, components, materials, or systems new or differentfrom those covered by the requirements in this standard, and that involve
42、s a risk of fire, electric shock, orinjury to persons shall be evaluated using the appropriate additional component and end-productrequirements to determine that the level of safety as originally anticipated by the intent of this standard ismaintained. A product whose features, characteristics, comp
43、onents, materials, or systems conflict withspecific requirements or provisions of this standard shall not be judged to comply with this standard.Where appropriate, revision of requirements shall be proposed and adopted in conformance with themethods employed for development, revision, and implementa

45、is standard shall comply withthe requirements for that component. See Appendix A for a list of standards covering componentsgenerally used in the products covered by this standard.2.1.2 A component need not comply with a specific requirement that:a) Involves a feature or characteristic not needed in
46、 the application of the component in theproduct covered by this standard orb) Is superseded by a requirement in this standard.2.1.3 A component shall be used in accordance with its recognized rating established for the intendedconditions of use.2.1.4 Specific components are recognized as being incom
47、plete in construction features or restricted inperformance capabilities. Such components are intended for use only under limited conditions, such ascertain temperatures not exceeding specified limits, and shall be used only under those specific conditionsfor which they have been recognized.2.2 Units
48、 of measurement2.2.1 If a value for measurement is followed by a value in other units in parentheses, the second valuemay be only approximate. The first stated value is the requirement.2.2.2 Unless otherwise indicated, all voltage and current values mentioned in this standard areroot-mean-square (rm
