A Public Address Voice Alarm (PAVA) system is a specialised emergency communication system designed to broadcast clear, intelligible voice messages to guide people during critical situations. Unlike standard public address (PA) systems, PAVA systems are specifically engineered for emergency evacuation scenarios and must comply with British fire safety regulations.

PAVA systems are a vital component in large buildings, transport hubs, commercial spaces, hospitals, shopping centres, and educational institutions, where effective communication can save lives in an emergency.

Key Features & Compliance

DIRECTING MESSAGES

Zoning in Voice Alarm Systems

Zoning technology is a fundamental feature of modern PAVA systems, ensuring that emergency messages are broadcast only where necessary.

Why Zoning Matters:

  • Minimises Unnecessary Alarm – Messages are targeted only at affected areas, preventing undue distress.
  • Supports Phased Evacuation Strategies – Critical in multi-storey buildings and large venues where a staggered evacuation is required.
  • Customisable Announcements – Specific instructions can be broadcast to different zones.

This feature is particularly essential in hospitals, airports, shopping centres, and industrial complexes where multiple evacuation zones may be in place.

FIRE & SECURITY NETWORKS

Seamless Integration

A well-integrated PAVA system works alongside fire alarms, security systems, and emergency response protocols to enhance safety.

Key Integration Features:

  • Automatic Activation – Fire detection systems trigger pre-recorded evacuation messages for faster and more controlled evacuations.
  • Link with CCTV & Access Control Systems – Helps monitor and coordinate emergency responses.
  • Failsafe Mechanisms – Includes battery backups and redundant signal paths to maintain system functionality during power outages.

WHEN TO USE EACH MODE

Automated vs Manual Voice Alarms

PAVA systems can operate in automated and manual modes, each serving distinct purposes:

  • Automated Messaging – Pre-programmed emergency instructions ensure a rapid and consistent response.
  • Manual Announcements – Allow real-time communication, providing specific instructions based on the developing situation.

For optimal emergency preparedness, most PAVA systems use a combination of both methods.
