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 the Rheingauer Weinmarkt in Frankfurt, serving stalls, walkways and visitor areas are spread across lanes and squares without continuous sound coverage. During evening peak periods and when visitors have been drinking, warnings, guidance messages and evacuation announcements must be clearly understood without delay. At the same time, temporary event areas in public spaces rely on mobile technology, while mobile networks can come under heavy strain when visitor numbers are high.
With 
, announcements, system monitoring, visitor information and device control come together on a single platform — fully independent of the public network. ![NIKOS [dispatcher]²](https://nikos.info/assets/logos/nikos/SVG/NIKOS dispatcher.svg)
controls individual announcement locations, selected areas or the entire site, allowing warnings and visitor information to be broadcast separately in lanes, squares and at access points, or across the entire venue. ![NIKOS [horn]²](https://nikos.info/assets/logos/nikos/SVG/NIKOS horn.svg)
supplements the audio output at locations without an existing sound system; ![NIKOS [audio]²](https://nikos.info/assets/logos/nikos/SVG/NIKOS audio.svg)
receives the voice transmission on site via radio and outputs it as an analogue audio signal. This reduces the need for materials, cabling and installation work. Staff travel, operating points and security posts are reduced because recurring tasks are controlled centrally and monitored or carried out by .
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. is designed for operation in crisis situations and remains usable even in the event of a power failure, damaged infrastructure or severely restricted network connectivity. The system operates autonomously and reliably keeps voice alarm coverage running for the Rheingauer Weinmarkt. has an internal battery with a runtime of up to 16 hours and also powers connected accessory modules. was specifically developed for flexible outdoor deployments without fixed infrastructure. One or two people can mount the modules on various structures such as lampposts, stages, stands or trees within just a few minutes and configure them individually. A standard Schuko power outlet is sufficient for continuous operation. centrally switches off all connected sound systems at the touch of a button. This makes it easier to obtain official approval and helps prevent complaints from local residents. is rented by the day through certified partners, including advice, instruction and technical support.
