Life safety is the primary purpose of any voice alarm system. Specific, real time information is proven to have clear advantages over conventional alarms for fire, security, chemical hazard or evacuation alert.
Speech and warning tones may be broadcast to specific groups of people or individuals across single or multi-zone areas.
The equipment can form part of a public address system, offering additional facilities such as paging, noise masking and background music. In either case, the voice alarm element is often interfaced with the fire alarm detection system for automatic alert and evacuation.
