The work of preparing Internationa

30、l 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. International organizations, governmental and non-governmental, in liaison with ISO,

31、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 the rules given in the ISO/IEC Directives, Part 2. The main task of technical commi

32、ttees 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 po

33、ssibility 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.

41、n 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 manually in a building or structure to alert occupants to a hazard which may require their evacuation in a safe and orderly manner. Equip

42、ment 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 automatic 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 conjunct

43、ion 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 combined with the fire detection control and indicating equipment (see ISO 7240-2). This part of ISO 7240 has been prepared by Subcommittee I

44、SO/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, video and multimedia systems and equipment. This part of ISO 7240 follows the format of, and has similar requirements to, ISO 7240-2 and is

45、 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 optional function is included as a separate entity, with its own set of associated requirements, in order for s.s.c.i.e. with different combi

46、nations 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 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

47、 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, direct impact, indirect shock and electromagnetic interference. Some tests specified are intended to assess the performance of the s.s.c.i.

48、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 any other restrictions on the design and construction of such equipment. SANS 7240-16:2008This s tandard may only be used and printed by
