The work of preparing International S
15、tandards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, als
16、o take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committe
17、es is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possi
18、bility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 7240-19 was prepared by Technical Committee ISO/TC 21, Equipment for fire protection and fire fighting, Subcommittee SC 3, Fire
19、detection and alarm systems. This first edition of ISO 7240-19 together with ISO 7240-16 cancels and replaces IEC 60849:1998, which has been technically revised.

25、rights reserved vii Introduction A sound system for emergency purposes (s.s.e.p.) alerts occupants to a hazard that can require their safe and orderly evacuation from the building. It operates automatically or manually. Equipment to alert building occupants is, therefore, required to function after
26、the hazard has been detected. Fire in a building is a common hazard that is often detected by an automatic fire detection and alarm system. A s.s.e.p. can operate as part of a fire detection and alarm system or can function in conjunction with other emergency detection systems. When used for emergen
27、cy purposes, it is recommended that the s.s.e.p. form part of a complete facility (equipment, operating procedures and training programmes) for the control of emergencies. The s.s.e.p. can be the subject of approval by relevant authorities. This part of ISO 7240 has been prepared by ISO/TC 21/SC 3 a
28、nd is based on IEC 60849:1998, Sound systems for emergency purposes prepared by the International Electrotechnical Commission IEC/TC 100 Audio, video and multimedia systems and equipment. This part of ISO 7240 contains specific requirements for the design, installation, commissioning and service of
29、sound systems for emergency purposes and follows the general format specified in ISO/TR 7240-14. INTERNATIONAL STANDARD ISO 7240-19:2007(E) ISO 2007 All rights reserved 1 Fire detection and alarm systems Part 19: Design, installation, commissioning and service of sound systems for emergency purposes
30、 1 Scope This part of ISO 7240 specifies the design, installation, commissioning and service requirements for a sound system for emergency purposes (s.s.e.p.; see ISO 7240-1:2005, Figure 1, item C), which is primarily intended to broadcast information for the protection of lives within one or more s
31、pecified 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 appli
32、cable) 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 distribu
33、tion 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. This part of ISO 7240 does not apply to sound systems that use bells or sounders. 2 Normative reference
