Fire detection and fire alarm system

The purpose of a voice alarm loudspeaker as a component of a voice alarm system is to provide intelligent warning to person(s) within, or nearby, a building in which a fire emergency has occurred and to enable such person(s) to take appropriate measure against a pre-determined evacuation plan.

The primary reason for using a voice alarm system instead of the coded warnings given by sounders is reduce the time taken for those at risk to recognize an emergency, and to give clear instructions on what to do next. This means that voice alarm loudspeakers need to achieve a minimum acoustic performance, as well as constructional and environmental requirements, to be suitable for use in fire detection and fire alarm system.

The EN-54-24 standard recognizes that the exact nature of the acoustic requirements for voice alarm loudspeakers will vary according to the nature of the space into which there are installed . Therefore specifies the minimum requirements that apply to voice alarm loudspeakers and a common method for testing their operational performance against parameters specified by the manufactures.

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 building.

Transducer which converts electrical energy into acoustical energy, comprising one or more enclosures a cable termination block, and relevant device such as filters, transformers and any passive element some loudspeakers are a combination of one or more loudspeaker housing(s) and a termination ox interconnected y a cable. The loudspeaker housing(s), Cable(s) and terminal ox should be considered to be “the loudspeaker” for the purpose of this European Standard. Examples of such loudspeakers include: pendant types and loudspeakers with mechanically adjustable orientation such as horn or column loudspeakers and loudspeakers arrays.
