12、:2010(E) iv ISO 2010 All rights reservedForeword 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
13、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
14、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
15、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

23、rvedIntroduction In a fire detection and alarm system, the purpose of the audible alarm devices is to warn person(s) within, or in the vicinity of, a building of the occurrence of a fire emergency situation in order to enable such a person(s) to take appropriate measures. Audible alarm devices using
24、 voice messages are also for warning the occupants of a building of the occurrence of a fire risk. These use a combination of an attention-drawing signal and dedicated voice message(s). Additional requirements, test methods and performance criteria specific to audible alarm devices with voice are al
25、so incorporated in this International Standard. Attention is drawn to ISO 8201, which specifies the temporal pattern and the required sound pressure level of an audible emergency evacuation signal. This part of ISO 7240 recognizes that the exact nature of the sound requirements, i.e. its frequency r
26、ange, temporal pattern and output level, will vary according to the nature of the installation, the type of risk present and appropriate measures to be taken, the type of signals used by other non-emergency alarms (see for example ISO 7731) and national differences in custom and practice. The result
27、ing standard specifies, therefore, a common method for testing of the operational performance of audible alarm devices against the specification declared by the manufacturer, rather than imposing common requirements. This part of ISO 7240 gives common requirements for the construction and robustness
28、 of audible alarm devices, as well as for their performance under climatic, mechanical and electrical interference conditions which are likely to occur in the service environment. Audible alarm devices have been classified in either an indoor or an outdoor application environment category. INTERNATI
29、ONAL STANDARD ISO 7240-3:2010(E) ISO 2010 All rights reserved 1Fire detection and alarm systems Part 3: Audible alarm devices 1 Scope This part of ISO 7240 specifies the requirements, test methods and performance criteria for audible alarm devices intended to signal an audible warning of fire betwee
30、n a detection and alarm system and the occupants of a building. It is intended to cover only those devices which derive their operating power by means of a physical electrical connection to an external source such as a fire alarm system. This part of ISO 7240 is also intended to cover audible alarm
31、devices capable of giving voice messages by the application of specific requirements, tests and performance criteria. This part of ISO 7240 specifies fire alarm audible alarm devices for two types of application environment, type A for indoor use and type B for outdoor use. This part of ISO 7240 is
32、not intended to cover: a) loudspeaker-type devices primarily intended for emitting emergency voice messages that are generated from an external audio source; b) supervisory audible alarm devices, e.g. within the control and indicating equipment. 2 Normative references The following referenced docume
