BS EN 54-24:2008EN 54-24:2008 (E) 6 Introduction The purpose of a voice alarm loudspeaker as a component of a voice alarm system is to provide intelligible warning to person(s) within
31、, or in the vicinity of, a building in which a fire emergency has occurred and to enable such person(s) to take appropriate measures against a pre-determined evacuation plan. The primary reason for using a voice alarm system instead of the coded warnings given by sounders is to reduce the time taken
32、 for those at risk to recognize that an emergency exists, and to give clear instructions on what to do next. This means that voice alarm loudspeakers need to achieve a minimum acoustical performance, as well as constructional and environmental requirements, to be suitable for use in fire detection a
33、nd fire alarm systems. This standard recognizes that the exact nature of the acoustical requirements for voice alarm loudspeakers will vary according to the nature of the space into which there are installed. It therefore specifies the minimum requirements that apply to voice alarm loudspeakers and
34、a common method for testing their operational performance against parameters specified by the manufacturers. This European Standard gives common requirements for the construction and robustness of voice alarm loudspeakers as well as their performance under climatic and mechanical conditions which ar
35、e likely to occur in the service environment. As the types of loudspeaker considered in this European Standard are passive electromechanical devices not involving sensitive electronic circuits, electromagnetic compatibility (EMC) tests have not been included. The loudspeakers have been classified in
36、 either an indoor or an outdoor application environment category. This European Standard requires that manufacturers specify certain characteristics in a consistent manner so that designers can make objective decisions about which loudspeaker to use in specific applications. BS EN 54-24:2008EN 54-24
37、:2008 (E) 7 1 Scope This European Standard specifies requirements, test methods and performance criteria for loudspeakers intended to broadcast a warning of fire between a fire detection and fire alarm system and the occupants of a building. This European Standard specifies loudspeakers for two type
38、s of application environment: type A, generally for indoor use and type B, generally for outdoor use. This European Standard does not cover loudspeakers for special applications, for example loudspeaker for use in hazardous applications, if such applications require additional or other requirements
39、or tests than those given in this European Standard. This European Standard is not intended to cover addressable loudspeakers, loudspeakers with active components. Voice alarm sounders are covered in EN 54-3:2001. 2 Normative references The following referenced documents are indispensable for the ap
