What is EN 54-24 for loudspeakers?
Quick answer
EN 54-24 is a European standard specifying requirements for loudspeakers used in voice alarm systems for fire detection and building safety, ensuring intelligibility and reliability during emergencies.
EN 54-24 is part of the EN 54 series of standards for fire detection and fire alarm systems. It specifically covers loudspeakers intended for voice alarm (VA) systems, which broadcast emergency announcements to aid evacuation. The standard defines performance criteria such as frequency response, sensitivity, maximum sound pressure level, and environmental endurance (e.g., temperature, humidity, corrosion resistance).
Compliance with EN 54-24 is mandatory in many European countries for loudspeakers installed in public buildings, airports, stadiums, and other venues where voice alarms are required. Manufacturers must undergo rigorous testing by notified bodies to certify that their products meet the standard's requirements. For professional audio brands like SSOUNDS, offering EN 54-24 certified loudspeakers ensures that systems can be legally deployed in European markets and provide reliable emergency communication.
Key aspects of the standard include verification of on-axis and off-axis frequency response, impedance, and the ability to maintain performance under simulated fire conditions. Loudspeakers must also demonstrate consistent sound distribution and intelligibility across their coverage area. SSOUNDS designs its voice alarm-compatible loudspeakers to exceed these requirements, combining high speech intelligibility with robust construction for critical safety applications.
