10、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 body interested in a subject for which a technical committee has been established has the right to be represented
11、 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 Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are draft
12、ed 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 by the technical committees are circulated to the member bodies for voting. Publication as an International Stan
13、dard 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 rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 7240-25 was prepared

ISO 7240-25:2010(E) vi ISO 2010 All rights reservedIntroduction This part of ISO 7240 is based on European Standard EN 54-25, prepared by the
21、 European Committee for Standardization, CEN/TC 72, Fire detection and fire alarm systems. This part of ISO 7240 defines requirements and tests in addition to those in other parts of ISO 7240 that allow components of a fire detection and alarm system using radio transmission paths to operate with an
22、 integrity and stability similar to those of wire transmission paths. This part of ISO 7240 includes both equipment and system requirements because of the integral relationship between equipment that forms the system. Limitations to the use of radio components, such as capacity, can be specified in
23、national rules or guidelines. Technical aspects of the assessment of frequencies, bands and channels should be considered. INTERNATIONAL STANDARD ISO 7240-25:2010(E) ISO 2010 All rights reserved 1Fire detection and fire alarm systems Part 25: Components using radio transmission paths 1 Scope This pa
24、rt of ISO 7240 specifies requirements, test methods and performance criteria for components used in fire detection and alarm systems, installed in and around buildings, which use radio-frequency (r.f.) transmission paths. It specifies requirements for the assessment of conformance of the components
25、to the requirements of this part of ISO 7240. Where components work together and this requires knowledge of the system design, this part of ISO 7240 also specifies requirements for the system. When the fire detection and alarm system uses wired and r.f. transmission paths, the relevant parts of ISO
26、7240 apply together with this part of ISO 7240. Requirements relevant to wire transmission paths are superseded or modified by those included in this part of ISO 7240. This part of ISO 7240 does not restrict the intended use of radio spectrum, e.g. frequency, power output of devices; the allowed max
27、imum number of the components using r.f. transmission paths within the fire detection and alarm system or one wire transmission path and/or r.f. transmission path; the allowed maximum number of the components affected by loss of one wire transmission path and/or r.f. transmission path. 2 Normative r
