A voice alarm system (sometimes referred to as a voice evacuation system) is installed with the safety of staff and general public in mind. It is a system that assists in the effective evacuation of an area or building during a fire, bomb alert or other emergency. At all other times a voice alarm system is used to make public address announcements, broadcast advertisements or background music. All broadcasts, be they live announcements or continual music, can be sent to all areas of a site or to selected areas (referred to as zones).
Each voice alarm system is designed and built specifically for each project – typically no two systems are identical. Used on a daily basis for public address, timed spot announcements for advertising or general information and background music, the voice alarm system is not just for use during emergencies.
The Code of Practice for Voice Alarm Systems is BS5839 Part 8 2013 along with the European Standard EN 60849-1999.
