The Platform

IP PA Architecture, Redefined.

WAVMerlaud is not an analogue system with an IP wrapper. It is a ground-up IP-native Public Address platform — every component, every protocol, every design decision made for the demands of modern networked infrastructure.

System Architecture

Three Layers. One Unified Platform.

The WAVMerlaud architecture separates concerns cleanly across three integrated layers — management, distribution, and output — each engineered to operate independently and fail gracefully.

The WAVHub management layer provides centralised control, monitoring, and configuration of the entire PA estate.

Technical Capabilities

Built for Scale. Designed for Reliability.

0+Zones

Zone Scalability

A single WAVMerlaud deployment can manage from a small 10-zone building to a national estate of 10,000+ zones.

<0ms

Audio Latency

End-to-end audio latency under 10 milliseconds across the IP network, ensuring synchronised announcements across all zones simultaneously.

<0sec

Failover Time

Automatic path failover in under one second. Dual-path redundancy ensures the system switches to a backup route before any announcement is audibly interrupted.

0Simultaneous

Audio Channels

Up to 256 simultaneous independent audio channels, enabling complex multi-zone, multi-source broadcast scenarios across large estates.

Standards & Compliance

Engineered to the Highest Safety Standards.

WAVMerlaud is designed from the ground up to meet the most demanding life safety and public address standards.

EN 54-16

Voice Alarm Control & Indicating Equipment

The WAVMerlaud management platform meets EN 54-16 requirements for voice alarm control equipment, including fault monitoring, priority override, and mandatory announcement routing.

EN 54-24

Loudspeakers for Voice Alarm Systems

Merlaud loudspeaker endpoints are certified to EN 54-24, ensuring intelligibility, coverage, and reliability in fire and emergency evacuation scenarios.

BS 5839-8

Voice Alarm Systems for Buildings

System design and installation follows BS 5839-8 guidance for voice alarm systems, including zoning strategy, coverage calculations, and commissioning requirements.

IEC 60849

Sound Systems for Emergency Purposes

The platform architecture satisfies IEC 60849 requirements for sound systems used in emergency situations, including redundancy, monitoring, and priority signalling.

System Integration

Works With Every System in Your Building.

WAVMerlaud is engineered to sit at the centre of your building's technology ecosystem — not in isolation. The WAVHub open API and hardware relay interfaces connect natively to the full range of life safety, environmental, security, and building automation systems found in modern commercial and industrial facilities.
