火灾探测和报警系统.第16部分:声音系统控制和指示设备

[中文适用范围]： ISO 7240 的这一部分规定了用于建筑物和构筑物的音响系统控制和指示设备 (sscie) 的要求、测试方法和性能标准，作为紧急音响系统 (ssep) 的一部分（ISO 中图 2 的项目 C） 7240-1:2005）。 sscie的主要目的是在紧急情况下在一个或多个指定区域内广播保护生命的信息，以实现室内或室外区域内人员快速有序的动员。 这包括使用扬声器广播紧急语音公告的系统、符合 ISO 7731 的警报信号以及符合 ISO 8201 的疏散信号。 ssep 的总体要求，特别是有关可听度和清晰度的要求，包含在 ISO 7240-19 中。 除了确保符合 ISO 7240 的这一部分外，制造商还应考虑影响 sscie 设计和可用性的 ISO 7240-19、国家法规、规范和标准的要求。 例如，某些法规要求管辖范围内安装的所有 sscie 均提供某些可选功能。 不排除在非危险情况下将设备用于正常扩声和分配系统目的。 ISO 7240 的这一部分还可用于评估在警告信号广播不包括语音消息的系统中使用的类似控制和指示设备。 ISO 7240 的这一部分不适用于仅使用发声器或铃声的系统。 [外文原描述]： ISO 7240-16:2007 specifies the requirements, test methods and performance criteria for sound system control and indicating equipment (s.s.c.i.e.) for use in buildings and structures as part of a sound system for emergency purposes (s.s.e.p.) aas defined in ISO 7240-1. The s.s.c.i.e. is primarily intended to broadcast information for the protection of lives within one or more specified areas in an emergency, to effect a rapid and orderly mobilization of occupants in an indoor or outdoor area. This includes systems using loudspeakers to broadcast voice announcements for emergency purposes, alert signals complying with ISO 7731, and evacuate signals complying with ISO 8201. The overall requirements of an s.s.e.p., especially concerning audibility and intelligibility, are contained within ISO 7240-19. In addition to ensuring compliance with ISO 7240-16:2007, the manufacturer should also consider the requirements of ISO 7240-19, national regulations, codes and standards that affect the s.s.c.i.e. design and usability. For example, some regulations require certain optional functions to be available on all s.s.c.i.e. installed within the jurisdiction. The use of the equipment for normal sound reinforcement and distribution systems purposes under non-hazardous circumstances is not excluded. ISO 7240-16:2007 can also be used for the assessment of similar control and indicating equipment for use in systems where the warning-signal broadcast does not include a voice message. ISO 7240-16:2007 does not apply to systems using only sounders or bells.
