EN54-24 is a European standard that specifies the requirements and performance criteria for fire detection and fire alarm systems incorporating voice alarm systems (VAS). EN54-24 addresses fireproof loudspeakers, which are a crucial component of voice alarm systems used for emergency voice communication during fire incidents.

Fire resistance: EN54-24 fireproof loudspeakers are designed to withstand fire conditions, constructed using fire-resistant materials and engineered to maintain their functionality and integrity in the presence of fire.

Evacuation messaging: These loudspeakers are designed to deliver clear and intelligible evacuation messages, including fire alarms, emergency instructions, and public address announcements, to guide people safely during fire emergencies. 

EN54-24 fireproof loudspeakers are intended for use in specific fire safety applications and should be installed and maintained according to local regulations and guidelines. They are a critical component in voice alarm systems, ensuring effective and reliable emergency communication during fire incidents.
