voice evacuation alarm system-BOSCH
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).
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. 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.
