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 intended to cover voice sounders by the application of additional requirements, tests and performance criteria detailed in Annex C.
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.
