IP Intercom, PA & Emergency Communication Systems for Critical Infrastructure

Advanced communication systems for critical infrastructure

ERMES develops IP-based communication solutions for applications where every second matters and every message must be delivered clearly. Our product range is designed to support operators, maintenance teams, passengers and emergency personnel with reliable communication tools.

Our main areas of expertise include:

IP Intercom Systems
Two-way communication systems for industrial sites, healthcare environments, public infrastructure and secure facilities, including applications aligned with EN 62820-2 requirements for critical situations.

IP Public Address Systems
Network-based public address and paging solutions using peer-to-peer technology, PoE loudspeakers, horn speakers and amplifier-based 100V distribution for voice communication and evacuation support.

Emergency Call Points and SOS Pillars
Emergency communication devices for roads, tunnels, public spaces, campsites, safe areas and smart city projects, with LAN, GSM/GPRS and LTE/4G connectivity options.

When communication fails, safety is at risk

In tunnels, railways, industrial plants and public infrastructures, communication systems must work every time, without compromise.

ERMES designs systems that help ensure:

• Immediate voice communication
• High reliability in harsh environments
• Easy integration with existing infrastructure
• Scalable IP architecture
• Regulatory alignment for critical applications

Applications in critical environments

ERMES communication systems are developed for infrastructures where clear voice transmission, rapid assistance and centralized control are essential.

Tunnels
Emergency call points, roadside assistance systems, operator communication and public address for road and rail tunnels.

Railways and Rolling Stock
Passenger communication, emergency intercom, platform communication and train-related audio systems for safe and efficient operation.

Highways and Roads
SOS pillars, roadside emergency stations and centralized communication systems for highway infrastructures.

Industrial Facilities
Robust intercom and PA solutions for plants, technical areas and challenging operating environments.

Public Areas and Safety Installations
Communication systems for campsites, refuge areas, service areas and public emergency points.

Standards and compliance

Critical communication systems must not only perform reliably, but also support compliance with the relevant technical framework. ERMES designs solutions for projects where standards, integration and long-term maintainability are key requirements.

Relevant standards and references may include:

• EN 62820-2 for intercom applications in critical environments
• EN 50849 for sound systems for emergency purposes not limited to fire scenarios
• Project-specific requirements for transport, public infrastructure and industrial safety

Our engineering team supports integrators and designers in selecting the most suitable architecture for the intended operational context.
