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.
ChallengeDuring the Berlin Marathon, spectators are spread across long, narrow sections of the route throughout the city. Bottlenecks, temporary closures and heavily used crossings require clear information for spectators, volunteers and security personnel. Status updates from course marshals must be available quickly so that areas can be opened or crowds redirected. At the same time, public communications networks are prone to disruption when visitor density is high and are not sufficiently reliable for safety-critical announcements.
Announcements, system monitoring, crowd management and device control come together with 
in a single platform independent of the public network. Quickly deployable, radio-based units reduce the need for long cable runs along the route and lower the effort required for materials, setup and support. ![NIKOS [dispatcher]²](https://nikos.info/assets/logos/nikos/SVG/NIKOS dispatcher.svg)
centrally addresses the announcement units at individual announcement locations, specific areas or across the entire site. ![NIKOS [audio]²](https://nikos.info/assets/logos/nikos/SVG/NIKOS audio.svg)
receives the voice transmission by radio on site and outputs it as an analogue audio signal. ![NIKOS [horn]²](https://nikos.info/assets/logos/nikos/SVG/NIKOS horn.svg)
extends acoustic coverage at positions without an existing public address system.
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. 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. controls the announcement units as required for individual announcement locations, specific areas or the entire site. This makes it possible to address the start and finish areas, bottlenecks, crossings or individual sections of the route separately or together. This improves the intelligibility of safety-critical announcements wherever spectators need to be directed or informed. operates via its own autonomous radio network and does not rely on mobile communications, the internet or other public communications networks. has an internal battery with a runtime of up to 16 hours and also powers connected accessory modules. This means crowd management for the Berlin Marathon remains reliably operational even if the power supply fails or public communications networks are disrupted. is designed for flexible outdoor use without fixed infrastructure. The modules can be installed by one or two people within a few minutes on a range of structures, such as lampposts, stages, stands or trees. A standard Schuko power connection is sufficient for continuous operation. is rented by the day through certified partners, including advice, instruction and technical support.
