NIKOS is not a conventional PA system, but a radio-based public address, alarm and control system for large events, construction sites and crisis situations, which you can rent by the day through certified partners and either integrate into your PA or use on its own.
ChallengeAt EXPO 2027 Belgrade, visitor information is a particular challenge due to crowds, a noisy environment and visitors who speak different languages. Important notices must reach visitors clearly and on time in different areas. When visitor density is high, the mobile network quickly becomes overloaded, meaning that mobile-based information channels may not be reliably available in a crisis.
brings together announcements, alerting, visitor guidance and device control in a single network-independent platform. ![NIKOS [dispatcher]²](https://nikos.info/assets/logos/nikos/SVG/NIKOS dispatcher.svg)
controls the announcement units for individual announcement locations, specific areas or the entire site. This allows information announcements to be triggered centrally, while fewer distributed operator stations are needed for visitor information. This reduces the staffing and installation effort required for temporary information structures.
meets the requirements of DIN EN 50849 for electroacoustic emergency warning systems. The system was developed specifically for safety-relevant announcements and alerting and is technically designed for both everyday operation and emergency situations. DIN EN 50849 represents the relevant reference framework for ELA systems. Unlike mobile network-based systems, does not depend on any external network and is therefore immediately ready for use at all times — fully meeting the standard as a result. Other standards known from safety technology, such as DIN EN 54, DIN VDE 0833-4 and DIN 14675 (voice alarm systems), do not apply to , as they are not applicable to radio-based public address systems like . is a public address system for temporary and mobile applications and has been used successfully many times for mission-critical communication tasks since 2017. RADACOM and your regional partner will be happy to advise you on ’s wide range of functions and support you in implementing the requirements cost-effectively. operates via its own autonomous wireless network and is completely independent of public communications networks and their availability. This makes the system highly resistant to external influences. Since does not rely on cable routes but communicates wirelessly, the connection is automatically re-established after an interruption. is therefore far more resilient to disruptions in regular operations than many other systems, demonstrating the crisis resilience of this communication system. ![NIKOS [audio]²](https://nikos.info/assets/logos/nikos/SVG/NIKOS audio.svg)
has an internal battery with a runtime of up to 16 hours and also supplies connected accessory modules. Even if the mobile network is overloaded, the internet provider has been hacked or someone has unplugged the wrong cable, continues to function. This ensures that visitor information for EXPO 2027 Belgrade remains reliably operational even in the event of a power failure or disruptions to public communications networks. was specifically developed for flexible outdoor deployments without fixed infrastructure. One or two people can mount the modules on different structures, such as lampposts, stages, stands or trees, within just a few minutes and configure them individually. A standard Schuko power connection is sufficient for continuous operation. If required, can also use an existing digital wireless network., announcements can be transmitted specifically to selected announcement locations, areas or the entire site. This ensures that visitors receive only the information relevant to the area in which they are located. be rented? is rented by the day through certified partners, including advice, instruction and technical support.
