Spaces

One platform. Every space.

WAVMerlaud runs the audio estate for transport hubs, retail malls, supermarkets, stadia, campuses, and industrial facilities — with continuous line supervision, EN54-16 certified emergency voice, and a single WAVMerlaud dashboard across every zone.

Sector solutions

Built for your environment

Transport
01

Mission-critical voice for airports, rail, and transit

Passenger information, emergency evacuation, and operational announcements across the most demanding environments in the world. WAVMerlaud delivers sub-10ms latency across thousands of zones — from departure gates to underground platforms — with supervised line integrity on every speaker endpoint.

10,000+Zones supported
<10msEnd-to-end latency
EN54-16Certified voice alarm
The challenge

Transport hubs require simultaneous multi-zone broadcasts, redundant failover, and integration with flight information display systems — all under EN54-16 life-safety mandates. A speaker that fails silently in a departure gate is a compliance failure, not just a maintenance issue. WAVMerlaud detects that failure before the next test broadcast.

FIDS integration

Direct API connection to flight information display systems for automated gate and delay announcements.

Redundant routing

Dual-path IP routing ensures no single point of failure across the entire PA network.

Multi-language TTS

Text-to-speech in 40+ languages for international passenger information.

Supervised line integrity

Every speaker circuit supervised continuously — open circuit, short, and impedance faults reported to the dashboard before a test broadcast.

Managed audio estate for shopping centres

Shopping centres and retail parks operate audio across dozens of tenancies, common areas, car parks, and service corridors — all of which need background music, paging, and EN54-16 emergency voice. WAVMerlaud manages the entire estate from a single instance, with continuous line supervision and a single dashboard across every zone.

Zone-levelIndependent tenancy control
EN54-16Certified emergency voice
The challenge

Mall operators inherit a patchwork of incompatible audio systems installed by different tenants and contractors over decades. A fire officer asking whether every speaker in the centre is working should not require a manual walkthrough. WAVMerlaud gives you that answer in real time.

Tenancy zoning

Independent audio environments per tenancy, floor, or area — all managed centrally from WAVMerlaud.

Scheduled messaging

Time-based and zone-specific announcements run automatically — no manual triggering required.

Fire panel interface

Direct interface to fire alarm panels for automatic EN54-compliant evacuation voice across all zones simultaneously.

Supervised line integrity

Every speaker circuit supervised continuously. Fault location to zone and circuit — not just loop level.

Zoned audio and in-store messaging for high-footfall retail

Supermarkets and quick-service restaurants need reliable background music, staff paging, and scheduled messaging across dozens or hundreds of sites — with EN54-16 emergency voice on every one. WAVMerlaud manages the full audio estate centrally, with per-site and per-zone scheduling, and supervised line integrity so a failed speaker is reported before a customer notices.

200+Sites on one platform
Zone-levelScheduled messaging
EN54-16Certified emergency voice
The challenge

Multi-site grocery and QSR operators manage audio through a mix of legacy systems, site-by-site contractors, and manual scheduling. A campaign that should play across 200 stores requires individual configuration on each. A speaker failure in a food preparation area goes undetected until a staff member reports it.

Centralised scheduling

Push background music and announcements to any combination of sites and zones from a single WAVMerlaud dashboard.

Supervised line integrity

Every speaker circuit supervised continuously. A failed speaker in any aisle or preparation area is reported immediately — not at the next test broadcast.

Staff paging

Zone-level staff paging with priority override of background music. Checkout calls, spill alerts, and security messages without interrupting the whole store.

Fire panel interface

Direct interface to fire alarm panels for automatic EN54-compliant evacuation voice across all zones.

BS 8524-compliant crowd management audio for high-capacity venues

High-capacity venues face a unique combination of acoustic challenges: crowd noise, complex geometry, and the legal requirement under BS 8524 to deliver intelligible emergency voice to every seat. WAVMerlaud's zone-level control and continuous monitoring meet that standard without compromise.

BS 8524Crowd management compliant
STI >0.5Speech intelligibility
100%Zone coverage verified
The challenge

Stadia operators must demonstrate to licensing authorities that their voice alarm system can reach every spectator with intelligible speech under crowd noise conditions. BS 8524 compliance requires documented evidence — not just a commissioning certificate.

BS 8524 compliance

System design and documentation aligned to BS 8524 requirements for crowd management voice alarm in sports grounds.

High-SPL zone control

Per-zone level management to achieve required STI scores under crowd noise conditions.

Event mode scheduling

Pre-programmed announcement sequences for pre-match, in-play, and evacuation scenarios.

Supervised line integrity

Every speaker endpoint supervised continuously — fault reports available to the safety officer in real time.

BB93-compliant audio for campuses where safety and acoustics both matter

Schools, universities, and healthcare facilities need PA systems that serve daily operations, lockdown protocols, and fire evacuation — all within the acoustic constraints of BB93 and the life-safety requirements of EN54. WAVMerlaud delivers a single managed platform across every building on campus, with Merlaud bridge devices connecting existing 100V line infrastructure so there is no rip-and-replace.

Multi-siteOne WAVMerlaud instance
30 secFull-campus alert time
Legacy100V line bridge — no rip-and-replace
The challenge

Education estates span multiple buildings, often added over decades, with incompatible legacy audio infrastructure. Healthcare facilities add the complexity of noise-sensitive clinical areas alongside high-priority emergency zones. The answer is not a new system for each building — it is one platform that bridges the old and manages the new.

Bell scheduling

Automated period bells, announcements, and timetable-linked audio events across all buildings.

Lockdown protocols

One-touch campus-wide lockdown with pre-recorded and live voice capability.

Legacy bridge

Merlaud hardware bridges existing 100V line infrastructure into the IP network — no rip-and-replace required.

Multi-site management

Manage every campus from a single WAVMerlaud instance with per-site access controls and independent zone scheduling.

Hazardous-area PA and supervised safety voice for industrial facilities

Manufacturing plants, warehouses, and process facilities need PA systems that operate reliably in high-noise, high-humidity, and potentially hazardous environments — and that integrate with safety systems including gas detection, fire suppression, and emergency shutdown. WAVMerlaud's hardware endpoints are rated for industrial environments, and WAVMerlaud integrates with the full range of industrial safety and automation systems.

IP65+Rated hardware endpoints
ATEXHazardous area options
EN54-16Certified emergency voice
The challenge

Industrial PA systems are often the last line of communication in an emergency — and the first to be neglected in maintenance schedules. A speaker in a noisy production area that has failed silently is a safety risk. WAVMerlaud's continuous line supervision means that failure is reported before the next safety drill.

Gas & hazard integration

Direct integration with gas detection, fire suppression, and emergency shutdown systems for automated safety announcements.

High-noise zone design

Acoustic modelling for high-ambient-noise environments — ensuring speech intelligibility in production areas and loading docks.

Supervised line integrity

Continuous supervision of every speaker circuit. A failed speaker in any zone is reported immediately — not discovered during a safety drill.

BMS and SCADA integration

Native integration with BMS, SCADA, and industrial automation systems via BACnet, Modbus, OPC-UA, and MQTT.
