miniVES and midiVES
Compact solutions for metro networks
miniVES and midiVES are compact, networked public address systems compliant with EN54, perfectly suited to the specifics of metro networks. Each system can function as an independent public address unit or as a component of a larger, centrally managed audio network.
System communication takes place via a TCP/IP network, enabling audio signal transmission and control over long distances. A key feature is remote monitoring and diagnostics, eliminating the need to dispatch a technician to the site, which reduces operational costs and response times.
These systems integrate with external security platforms such as SCADA, VMS, or PSIM. Furthermore, by capturing digital audio streams (UDP, SIP), they ensure easy integration with passenger information systems (PIS) and IP telephony, allowing for automatic announcements and flexible voice communication management throughout the metro infrastructure.

Intercom System
Integrated Solution for Metro
In metro environments, where rapid response and reliability are crucial, the Intercom System provides an integrated two-way voice communication solution. It forms the foundation of safety and operational efficiency, enabling immediate information exchange.
The system is based on SIP technology, utilizing operator consoles that combine the functions of advanced dispatch stations with IP telephony capabilities. Thanks to the ISE COMM server, integration with existing telephone networks and mobile devices is possible, ensuring communication flexibility and reach. The Intercom System enables voice communication within an IP network and is also adapted for close integration with public address and PAVA.

Audio network architecture
The extensive metro infrastructure, encompassing numerous stations and technical facilities, requires a flexible audio architecture.
Each of these locations is equipped with a public address system capable of autonomous operation, guaranteeing local safety and communication even in the event of network connectivity loss. Simultaneously, all these systems form an integral part of a centralized audio network, enabling message management and coordination from a single point.
System Integrations: Centralized Management and automation in metro
Effective management of metro infrastructure, from safety to daily communication, relies on system integration. Metro public address systems are designed for full compatibility and digital connection with central visualization and security systems, such as SCADA and PSIM, enabling metro staff to efficiently manage operational functions.
Integration with Fire Alarm System (FAS)
In an emergency, the PAVA enables automatic emission of evacuation messages.
Integration with Passenger Information System (PIS)
Allows for automatic broadcasting of timetable and train movement announcements, increasing passenger service fluidity.
Integration with Metro IP Telephony Systems
Full control over product development allows for adapting solutions to changing market needs and specific client requirements.
Specialized loudspeakers
The reliability of voice communication in the metro depends
on the use of specialized loudspeakers.
on the use of specialized loudspeakers.
They must meet a range of design requirements, including: high mechanical resistance (to impacts and vandalism), ability to operate in a wide temperature range, full resistance to moisture and corrosion, and durability against long-term vibration.
