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 CHIO Aachen, visitor information must remain clear even when visitor volumes are high, ambient noise is present and visitors move between different areas. Visitors need to receive up-to-date information about procedures, areas and safety-related situations without delay. In the event of a power outage or an overload of public communication networks, information delivery must not fail.
Instead of multiple separate solutions: 
unites visitor information, system monitoring, visitor guidance and 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 event site. This reduces the need for separate control technology, cabling and operator stations, while enabling current visitor information to be delivered precisely where it is needed.
meets the requirements of DIN EN 50849 (electroacoustic emergency warning systems). was developed specifically for safety-relevant public address and alerting applications and is technically designed for use in both everyday and emergency situations. For electroacoustic emergency warning systems, DIN EN 50849 is the relevant reference framework. Unlike mobile network-based systems, fully meets the requirements specified therein, as it does not depend on an external network and can therefore be used immediately at any time. 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 the field of use and functional scope of and are therefore not relevant for approval. is a public address system for temporary and mobile applications and has been successfully deployed in numerous mission-critical communication tasks since 2017. RADACOM and your regional partner will be happy to advise you on the wide range of functions and support you in implementing the requirements cost-effectively. combines visitor information, employee alerting and system control in a single communication platform. mainly reduces the effort required for separate loudspeaker, control and communication solutions. Material requirements and cabling work are reduced, and information and emergency announcements can be made from a single location. Centralized operation replaces multiple reporting and operator stations distributed across the site. This reduces installation effort and enables personnel to be deployed precisely at safety-critical points. was developed for flexible outdoor deployments without fixed infrastructure. One or two people can mount and configure the modules on structures such as lampposts, stages, stands or trees within just a few minutes. A standard Schuko power outlet is sufficient for continuous operation. operates via an autonomous radio network and independently of public communication networks. Since communicates without cable runs, the connection is automatically re-established after an interruption. ![NIKOS [audio]²](https://nikos.info/assets/logos/nikos/SVG/NIKOS audio.svg)
has an internal battery with up to 16 hours of operating time and also powers connected accessory modules. Visitor information for CHIO Aachen therefore remains functional in the event of a power failure or disruptions to public communication networks. is rented by the day through certified partners, including advice, instruction and technical support.
