Emergency announcement systems save lives during fire or security incidents. EN54 Part 16 ensures reliable performance.
PA vs VA
PA handles general announcements. VA adds fire-rated speakers, automatic emergency messages, fail-safe operation. Combined PA/VA serves both.
Zone Design
Divide buildings into zones aligned with fire compartments. Each zone needs independent speaker circuits with line monitoring.
Integration
VA must integrate with fire detection for automatic activation. Pre-recorded evacuation messages play on fire alarm trigger.
