NIKOS – Jahrmarkt

Evacuation announcements for Hamburg DOM

autonomous reliable cost-effective

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.

Challenge

Safety announcements must remain intelligible despite noise and crowds

At Hamburg DOM, large numbers of visitors move between rides, food stalls, and showmen’s attractions. Sound systems, rides, and crowd noise create a constantly high level of ambient noise, making safety-related announcements difficult to understand. In an emergency, evacuation announcements must reach all visitors clearly, without their intelligibility being impaired by noise, crowds, or overloaded mobile phone networks.

Solution

One unified solution for everyday use and emergencies

NIKOS combines announcements, alerting, visitor information and control in a single, network-independent platform. NIKOS [audio]² interrupts the showmen’s sound systems for the duration of an announcement, significantly reducing the ambient noise level. NIKOS uses existing sound systems for evacuation announcements; NIKOS [horn]² supplements audio output at locations without an existing public-address system. Central control via NIKOS [dispatcher]² reduces the need for separate announcement systems, operator routes, and setup work, because individual announcement locations, specific areas, or the entire site can be addressed from a single point.

FAQ

Information for planners and organisers

Are announcements made via NIKOS standard-compliant?+
Yes — NIKOS fully meets DIN EN 50849 (electroacoustic emergency warning systems). The system was designed specifically for safety-relevant announcement and alerting tasks, technically built for everyday operation as well as for emergencies. For ELA systems, DIN EN 50849 sets out the relevant framework. Because NIKOS — unlike mobile network-based solutions — does not depend on any external network, it is always immediately usable and fully meets the requirements set out in the standard. Other safety-related standards such as DIN EN 54, DIN VDE 0833-4 or DIN 14675 (voice alarm systems) concern a different field of use and functional scope and are therefore not relevant for NIKOS in terms of approval. Since 2017, NIKOS has been used successfully many times a public address system for temporary and mobile applications in mission-critical communication tasks. RADACOM and your regional NIKOS partner will be happy to advise you on the wide range of NIKOS functions and support you in implementing the requirements cost-effectively.
Where does NIKOS deliver cost savings?+
Depending on the application, NIKOS can combine different functions on a single communications platform. These savings can quickly offset the rental and installation costs of NIKOS. You can find some specific examples of savings here. NIKOS 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.
Is NIKOS resilient in a crisis?+
Yes. NIKOS operates via its own autonomous radio network and is completely independent of public communications networks and their availability. Because NIKOS does not rely on cable connections but communicates via radio, the connection is automatically re-established after an interruption. NIKOS [audio]² has an internal battery providing up to 16 hours of runtime and also powers connected accessory modules. This ensures that evacuation announcements at Hamburg DOM remain reliably operational even in the event of a power failure or disruptions to public communications networks.
Can NIKOS be deployed at Hamburg DOM at short notice and with flexibility?+
Yes. NIKOS 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.
