火灾探测和报警系统.第19部分:应急用发声系统设计、安装、交付使用和服务

[中文适用范围]： ISO 7240 的这一部分规定了紧急情况下音响系统的设计、安装、调试和服务要求（ssep；参见 ISO 7240-1:2005，图 1，项目 C），其主要目的是为了保护广播信息紧急情况下一个或多个指定的室内或室外区域内的生命。 SSEP 旨在在紧急情况下快速有序地动员居住者，方法是使用扬声器广播紧急情况下的语音公告、符合 ISO 7731（如适用）的警报信号和符合 ISO 8201 的疏散信号。 ，优先使用声音系统而不是发声器或警铃，以广播一系列难以与发声器或警铃通信的编码警告。 不排除在非危险环境下将 ssep 用于正常扩声和分配系统目的。 当用于非紧急目的时，扬声器的分区可以与用于紧急目的的区域不同。 ISO 7240 的这一部分不适用于使用铃声或发声器的音响系统。 [外文原描述]： ISO 7240-19:2007 specifies the design, installation, commissioning and service requirements for a sound system for emergency purposes (s.s.e.p.), which is primarily intended to broadcast information for the protection of lives within one or more specified indoor or outdoor areas during an emergency. The s.s.e.p. is intended to initiate a rapid and orderly mobilization of occupants in an emergency by including systems using loudspeakers to broadcast voice announcements for emergency purposes, alert signals complying with ISO 7731 (where applicable) and evacuation signals complying with ISO 8201. In some cases, sound systems are used in preference to sounders or bells in order to broadcast a range of coded warnings that is difficult to communicate with sounders or bells. The use of the s.s.e.p. for normal sound reinforcement and distribution systems purposes under non-hazardous circumstances is not excluded. When used for non-emergency purposes, the zoning of the loudspeakers can differ from the zones used for emergency purposes. ISO 7240-19:2007 does not apply to sound systems that use bells or sounders.
