EN54 Voice Alarm
– to Save Human Lives!
During an emergency situation in buildings, the most important tasks are to get all the people out of the danger zones as fast as possible and to avoid any kind of mass panic. Especially in big buildings like public institutions or schools, precious time in rescue could be lost. Scientific studies have clearly proven that targeted information transmitted via voice announcements will gain valuable time over common signalling devices such as sirens or horns.
Precise instructions for evacuation can be transmitted via voice announcement, and panic situations can be prevented through reassuring messages. Additionally, voice announcements can be multi-lingual, even live announcements from the fire brigade can be streamed. All these advantages of voice alarm allow a considerably faster and more systematic evacuation of buildings and thus save lives.
Product specifications for voice alarm systems, loudspeakers, and emergency power supply were put into effect Europe-wide on 01.04.2011 to guarantee a standardised level of security and quality.

- Fire detection and fire alarm systems - Part 16: Voice alarm control and indicating equipment
