This European Standard specifies the requirements, test methods and performance criteria for fire alarm sounders, including voice sounders, in a fixed installation intended to signal an audible warning between the fire detection and fire alarm systems and the occupants of a building (see EN 54‑1:2011 ).

This European Standard provides for the assessment and verification of constancy of performance (AVCP) of fire alarm sounders to this EN.

This European Standard is not intended to cover:

  1. loudspeaker type devices primarily intended for emitting emergency voice messages that are generated from an external audio source;

  2. supervisory sounders, for example, within the control and indicating equipment.
