A Voice Alarm System (VAS) is a life-safety communication system designed to deliver clear spoken emergency messages during critical situations such as fire, evacuation, or security incidents. Unlike conventional sounders or sirens, voice alarm systems provide intelligible instructions, helping occupants respond calmly and safely.

Voice alarm systems are widely used in commercial buildings, airports, hospitals, shopping malls, hotels, educational institutions, industrial facilities, and public infrastructure. These systems typically integrate voice alarm controllers, amplifiers, backup power supplies, paging microphones, and EN54-24 certified loudspeakers.

Modern voice alarm systems comply with EN54-16 and EN54-24 standards and seamlessly integrate with fire alarm systems (FAS) to automatically trigger evacuation messages. Advanced systems also support zoning, message prioritization, redundancy, monitoring, and integration with PA and IP-based communication platforms.

A properly designed voice alarm system enhances occupant safety, ensures regulatory compliance, and provides reliable emergency communication in mission-critical environments.
