Voice Alarm System (VAS)
Controlled evacuation through clear and intelligible voice announcements. Modern APS®-APROSYS, APS®-ARIA, APS®-FLEX, VA-450 and VA-500 Voice Alarm Systems provide reliable emergency voice communication for buildings of all sizes, ensuring safe and efficient evacuation during fire emergencies.
What is a Voice Alarm System?
Clear Voice Instructions for Safe and Orderly Evacuation
A Voice Alarm System (VAS) is designed to initiate and manage the evacuation of building occupants through clear and intelligible voice announcements. Unlike conventional alarm sounders, it provides precise information about the emergency and instructs occupants on the appropriate actions to take.
A Voice Alarm System helps reduce panic, speeds up the evacuation process and enables controlled evacuation based on predefined zones, emergency scenarios and the type of incident.
Applications

HOW A VOICE ALARM SYSTEM WORKS
From Fire Detection to the Safe Evacuation of Occupants
The Voice Alarm System (VAS) works in conjunction with the Fire Detection System (FDS) and other building technologies. Once an emergency has been detected and verified, the system automatically activates voice announcements, providing clear instructions to help occupants leave the building safely and efficiently.
Incident Detection
The Fire Detection System (FDS) or another safety system detects a fire or other emergency situation.
Scenario Evaluation
The system identifies the affected zones and selects the appropriate evacuation scenario based on the type of incident and predefined operating rules.
Voice Announcement Activation
Loudspeakers automatically broadcast pre-recorded emergency messages or live announcements from the operator.
Controlled Evacuation
Occupants receive clear and intelligible voice instructions, helping to reduce panic and ensure a safe and orderly evacuation of the building.
Incident Coordination
The Voice Alarm System remains active throughout the incident, providing continuous information to occupants and supporting the coordination of emergency response teams.
System Components
Key Components of a Voice Alarm System
A Voice Alarm System consists of advanced technologies that ensure reliable emergency voice announcements, intelligible message transmission and controlled distribution of announcements throughout individual zones of the building.
Voice Alarm Control Panel
APS®-APROSYS and APS®-ARIA Voice Alarm Control Panels manage voice announcements, evacuation scenarios and audio distribution throughout the building.
Loudspeakers
EN 54-certified loudspeakers provide clear and intelligible voice announcements throughout protected areas and evacuation zones.
Firefighter Microphone Station
Enables live voice announcements by the operator or authorised personnel during an evacuation or other emergency situation.
Backup Power Supply
Ensures continuous system operation even in the event of a mains power failure.
Evacuation Zones
Allow announcements to be directed only to selected areas of the building according to the active evacuation scenario.
Fire Detection System Integration
The Voice Alarm System integrates with the Fire Detection System (FDS) and automatically activates the appropriate voice announcements according to the detected emergency.
