紧急车辆警报器

[中文适用范围]： 本SAE推荐实践提供了实验室测试程序、要求和指南，适用于带有单个扬声器的电子警报系统以及用于授权紧急车辆上的机电警报器，这些车辆需要优先通行权。本版本不包括单个系统组件的测试程序和性能要求。对于任何尺寸大于0.5米的扬声器阵列的警报系统，只有当阵列的空间配置与测试时相同（即相同的扬声器间距和方向）时，结果才适用于该系统。 [外文原描述]： This SAE Recommended Practice provides laboratory test procedures, requirements, and guidelines for electronic siren systems with a single loudspeaker, and electromechanical sirens for use on authorized emergency vehicles, which call for the right-of-way. Test procedures and performance requirements for individual system components are not included in this version. Results obtained for a siren system with a speaker array that is greater than 0.5 m in any dimension shall apply to the system only when the array is in the same spatial configuration as tested (i.e., the same speaker separation and orientation).Cross Reference: ANSI/S1.1,ANSI/S1.15,ANSI/S1.4,ANSI/S1.40,ANSI/S1.42,CISPR25,IEC61094-1,IEC61094-4,J1113-21,J1113/21,J336,J575_201508,J759_201404,J994_201409
