22、f national standards bodies (ISO member bodies). The work of preparing International Standards 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. In
23、ternational organizations, governmental and non-governmental, in liaison with ISO, also 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
24、the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees 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
25、 by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility 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 7240-16 was prepared by Technical Committe
26、e ISO/TC 21, Equipment for fire protection and fire fighting, Subcommittee SC 3, Fire detection and alarm systems. This first edition of ISO 7240-16 together with ISO 7240-19 cancels and replaces IEC 60849:1998, which has been technically revised. ISO 7240 consists of the following parts, under the

ISO 7240-16:2007(E) viii ISO 2007 All rights reservedIntroduction Sound system control and indicating equipment (s.s.c.i.e.) forms part of a sound system for emergency purposes (s.s.e.p.). An s.s.e.p. operates automatically or
33、manually in a building or structure to alert occupants to a hazard which may require their evacuation in a safe and orderly manner. Equipment to warn occupants is therefore required to function after the hazard has been detected. Fire in a building is a common hazard which is often detected by an au
34、tomatic fire detection and alarm system. An s.s.e.p. may operate as part of a fire detection and alarm system or may function in conjunction with other emergency detection systems, such as those for storms, earthquakes and bomb threats. The s.s.c.i.e. may be a separate unit or may be physically comb
35、ined with the fire detection control and indicating equipment (see ISO 7240-2). This part of ISO 7240 has been prepared by Subcommittee ISO/TC 21/SC 3 and is based on IEC 60849:1998, Sound systems for emergency purposes, prepared by the International Electrotechnical Commission IEC/TC 100, Audio, vi
36、deo and multimedia systems and equipment. This part of ISO 7240 follows the format of, and has similar requirements to, ISO 7240-2 and is drafted on the basis of mandatory functions which are to be provided on all s.s.c.i.e. and optional functions (with requirements) which may be provided. Each opti
37、onal function is included as a separate entity, with its own set of associated requirements, in order for s.s.c.i.e. with different combinations of functions to comply with this part of ISO 7240. It is intended that the options be used for specific applications, as recommended in ISO 7240-19 and the
38、 emergency management plan. Other functions associated with an s.s.e.p. may also be provided, even if they are not specified in this part of ISO 7240. This part of ISO 7240 contains specific tests that subject the equipment to conditions likely to be met in practice, such as corrosion, vibration, di
39、rect impact, indirect shock and electromagnetic interference. Some tests specified are intended to assess the performance of the s.s.c.i.e. under such conditions. The performance of the s.s.c.i.e. is assessed from the results obtained in specific tests. This part of ISO 7240 is not intended to place
40、 any other restrictions on the design and construction of such equipment. INTERNATIONAL STANDARD ISO 7240-16:2007(E) ISO 2007 All rights reserved 1 Fire detection and alarm systems Part 16: Sound system control and indicating equipment 1 Scope This part of ISO 7240 specifies the requirements, test m
41、ethods 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.) (item C of Figure 2 in ISO 7240-1:2005). The s.s.c.i.e. is primarily intended to broadcast information for th
42、e 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
43、 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 this part of ISO 7240, the manufacturer should also consider the requirements of ISO 724
44、0-19, 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 distribut
45、ion systems purposes under non- hazardous circumstances is not excluded. This part of ISO 7240 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. This part of ISO 7240 does not apply
46、to systems using only sounders or bells. 2 Normative references The following referenced documents are indispensable for the application of this document.
