PA Voice Alarm SystemVoice alarm systems are 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 or broadcast advertisements. All broadcasts can be sent to all areas of a site or to selected areas, which are referred to as zones.

Research has proven that in an emergency people will react without confusion or panic if they receive a clear, intelligible message. These messages are stored within a voice alarm system. Although traditional bells and sounders only give a warning, they do not indicate the nature of the emergency, leaving people uncertain and often such signals are ignored – with fatal consequences. A voice alarm system provides clear easily understood instruction via pre-recorded messages. This method ensures that even untrained personnel and the general public are evacuated speedily and efficiently.

PA VA Voice Alarm Systems can be installed within all offices, factories, warehouses, shops, sports stadiums, cinemas, theatres, schools and public buildings, integrating with any fire alarm system to ensure that alert and evacuation messages are broadcast clearly. A voice alarm system has to work when needed – during an emergency – and is, therefore, fully monitored at all times. It is also backed up by batteries which are fully charged and checked constantly; this will ensure that, even during a mains power failure, the system will continue to operate. A combination of clear pre-recorded messages and live announcements (to selected areas) enable a controlled and gradual or ‘phased’ evacuation. ‘Phased evacuation’ methods enable selected areas to be evacuated in turn – typically those in most danger are evacuated first whilst surrounding areas (zones) are put on ‘alert’. The voice alarm system works automatically, with all controls easily overridden by fire officers or building control when needed.

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.

Voice Alarm Systems are specifically designed to meet the life safety issues contained within BS 5839 Part 8.
