This European Standard specifies the requirements, test methods and performance criteria for fire alarm sounders in a fixed installation intended to signal an audible warning of fire between a fire detection and fire 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 standard specifies fire alarm sounders for two types of application environment, type A for indoor use and type B for outdoor use. This standard is not intended to cover: a) loudspeaker type devices primarily intended for emitting emergency voice messages; b) supervisory sounders, for example, within the control and indicating equipment.
