16、9:2010(E) ISO 2010 All rights reserved vForeword ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member bo

17、dy 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, also take part in the work. ISO collaborates closely with the International Electrot

18、echnical 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 committees is to prepare International Standards. Draft International Standards adopted b

19、y 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 possibility that some of the elements of this document may be the subject of patent ri

20、ghts. ISO shall not be held responsible for identifying any or all such patent rights. ISO 12239 was prepared by Technical Committee ISO/TC 21, Equipment for fire protection and fire fighting, Subcommittee SC 3, Fire detection and alarm systems. This second edition cancels and replaces the first edi

21、tion (ISO 12239:2003), which has been technically revised. ISO 12239:2010(E) vi ISO 2010 All rights reservedIntroduction This International Standard for smoke alarms is drafted on the basis of functions that are to be provided on all smoke alarms covered by this standard, and optional functions with

22、 requirements which may be provided. It is intended that the options shall be used for specific applications, as recommended in application guidelines. Each optional function is included as a separate entity, with its own set of associated requirements, in order to permit smoke alarms covered by thi

23、s standard with different combinations of functions to conform to this International Standard. Two optional sound output levels are specified in this International Standard. The options allow national regulators to specify minimum sound output levels (70 dBA or 85 dBA) as required under national reg

24、ulations. Two optional sound output patterns are specified in this International Standard. The options allow national regulators to choose a sound pattern complying with ISO 8201 or ISO 7731 depending on the desired response by building occupants to an alarm condition. An optional extended temperatu

25、re-range test is included for smoke alarms installed in areas subject to a greater temperature range, such as leisure accommodation vehicles. Other functions may also be provided, even if not specified in this International Standard, if they do not jeopardize any function required by this document.

26、INTERNATIONAL STANDARD ISO 12239:2010(E) ISO 2010 All rights reserved 1Smoke alarms using scattered light, transmitted light or ionization IMPORTANT Certain types of smoke alarms contain radioactive materials. The national requirements for radiation protection differ from country to country and they

27、 are not specified in this International Standard. Such smoke alarms should, however, comply with the applicable national standards, which should be consistent with the recommendations of the Nuclear Energy Agency (NEA) of the Organisation for Economic Co-operation and Development (OECD). 1 Scope Th

28、is International Standard specifies requirements, test methods, performance criteria, and manufacturers instructions for smoke alarms that operate using scattered light, transmitted light, or ionization, and are intended for household or similar residential applications. For the testing of other typ

29、es of smoke alarms, or smoke alarms working on different principles, this International Standard should be used only for guidance. Smoke alarms with special characteristics and developed for specific risks are not covered by this International Standard. This International Standard allows, although i

30、t does not require, the inclusion within the smoke alarm of facilities for the following: visual alarm condition indication; visual fault condition indication; extended temperature-range operation; interconnection with other similar smoke alarms or accessories; alarm-silencing facility. Where such f

31、acilities are included, this International Standard specifies applicable requirements. This International Standard does not cover devices intended for incorporation in systems using separate control and indicating equipment. Such systems are specified in all parts of ISO 7240. 2 Normative references
