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 open-air festivals, a public address system faces particular challenges due to crowds, high noise levels and visitors who speak different languages. Stages, sound systems and large visitor numbers make it difficult to communicate warnings and instructions clearly across all areas. At the same time, during periods of high demand, the mobile network cannot be reliably relied upon for crisis communication.
With 
, announcements, system monitoring, visitor information and device control come together on a single platform — fully independent of the public network. ![NIKOS [audio]²](https://nikos.info/assets/logos/nikos/SVG/NIKOS audio.svg)
enables mobile announcements without extensive cabling. The radio connection reduces the amount of material and installation work required, thereby lowering the cost of temporary public address infrastructure.
fully meets DIN EN 50849 "Electroacoustic Emergency Warning Systems". The system was specifically designed for safety-relevant announcements and alerting and is technically built for both everyday and emergency use. DIN EN 50849 is the relevant standard for radio-based ELA systems such as . Because , unlike mobile network-based systems, operates independently of an external network, immediate usability is guaranteed at all times — fully meeting the standard's requirements as a result. Other safety-related standards such as DIN EN 54, DIN VDE 0833-4 and DIN 14675 (voice alarm systems), by contrast, do not apply to , as they concern a different field of use and functional scope and are therefore not relevant to 's deployment. As the only public address system for temporary and mobile applications consistently designed around the demands of mission-critical use, has been used successfully for crisis-proof communication tasks since 2017. Official acceptance is carried out on a project-specific basis. operates via its own autonomous radio network and independently of public communications networks and their availability. Since does not rely on wired connections but communicates via radio, the connection is automatically re-established after an interruption. has an internal battery providing up to 16 hours of operating time and also powers connected accessory modules. This means public address systems for open-air festivals remain reliably operational even if the power supply fails or public communications networks are disrupted. was specifically developed for flexible outdoor use without permanent infrastructure. One or two people can mount the modules on different structures such as lampposts, stages, stalls or trees within just a few minutes and configure them individually. A standard Schuko power outlet is sufficient for continuous operation. also uses an existing digital radio network.![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 announcements to be transmitted to the designated event areas in line with the situation at hand. is rented by the day through certified partners, including consultation, instruction and technical support.
