ISO 7240-19:2007规定了应急音响系统(s.s.e.p.)的设计、安装、调试和服务要求,该系统主要用于在紧急情况下广播信息,以保护一个或多个指定室内或室外区域内的生命。s.s.e.p.旨在通过包括使用扬声器播放紧急语音通知的系统、符合ISO 7731(如适用)的警报信号和符合ISO 8201的疏散信号,在紧急情况下启动快速有序的人员动员。在某些情况下,音响系统优先于发声器或铃铛使用,以便广播一系列难以与发声器或铃铛通信的编码警告。
不排除在非危险情况下将s.s.e.p.用于正常扩声和分配系统。
当用于非紧急用途时,扬声器的分区可能与用于紧急用途的分区不同。
ISO 7240-19:2007不适用于使用铃铛或发声器的音响系统。
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.
