12、 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. International organizations, governmental and non-

13、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. The procedures used to develop this document and those intended for its further maintenance are describ

14、ed in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the different types of ISO documents should be noted. This document was drafted in accordance with the editorial rules of the ISO/IEC Directives, Part 2. www.iso.org/directives Attention is drawn to the po

15、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.

24、ons are fulfilled: materials are of a suitable quality; special knowledge in the field of fire detection and fire alarm; skilled personnel to carry out the work. Although the quality of the material can be ensured by proper standards and quality audits, the overall effectiveness of an installation d

25、epends widely on the quality of work, the experience of the designer and installer, and regular service. This part of ISO 7240 has been prepared by ISO/TC 21/SC 3. A number of existing national codes and standards were reviewed during the preparation of this edition of this part of ISO 7240. Althoug

26、h there are minor differences in, for example, detector spacing requirements, each code or standard has the same objective of early fire detection. This part of ISO 7240 specifies the minimum requirements for fire detection and alarm systems using equipment complying with ISO 7240. ISO 2013 All righ

28、d alarm system (FDAS) (see ISO 7240-1, Figure 1), which is primarily intended to provide early detection of fire and notification within one or more specified indoor or outdoor areas for the protection of lives. The FDAS includes automatic detection of a fire and manual initiation of a fire alarm, w

29、ith audible and visual warning to people within the detection area. This part of ISO 7240 also specifies requirements for FDAS capable of providing signals to audible warning systems in accordance with ISO 7240-19, to initiate the operation of ancillary technical services, such as fixed fire extingu

30、ishing systems, and to other precautions and actions. The protection of property is outside the scope of this part of ISO 7240. However, the requirements specified herein may be used as recommendations for property protection. 2 Normative references The following documents, in whole or in part, are
