NIKOS – Lange Nacht der Museen

Emergency Announcements for the Long Night of Museums in Berlin

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

Distributed venues need a shared warning and announcement layer

During the Long Night of Museums in Berlin, visitors are spread across numerous venues, routes and entrance areas rather than concentrated in a single event area. In a hazardous situation, warnings and instructions must reach people across all locations clearly and simultaneously. Public communication networks are not a reliable channel for mission-critical announcements when network usage is high. Different building systems and changing noise levels also make coordinated emergency communication more difficult.

Solution

One unified solution for everyday use and emergencies

NIKOS brings together announcements, alerting, visitor guidance and device control in a single network-independent platform. NIKOS [dispatcher]² controls the announcement units as needed, addressing individual announcement locations, specific areas or the entire site. This enables entrances, outdoor areas and temporary information points to be served consistently. NIKOS [audio]² receives voice transmissions on site via radio and outputs them as an analogue audio signal; NIKOS [horn]² supplements the acoustic output at locations without an existing public address system. This eliminates the need for separate loudspeaker, control and communication solutions. Staff travel, operator stations and security posts are reduced because recurring tasks are controlled centrally and monitored or carried out by NIKOS.

FAQ

Information for planners and organisers

Does NIKOS meet the applicable standards for announcements?+
Yes, NIKOS is standard-compliant: the system meets DIN EN 50849 for electroacoustic emergency warning systems. NIKOS was developed specifically for safety-relevant announcements and alerting — usable both in everyday operation and in an emergency. For ELA systems, DIN EN 50849 forms the decisive reference framework. Unlike mobile network-based systems, NIKOS fully meets these requirements because it operates independently of an external network and is therefore immediately ready for use at any time. Other safety-related standards such as DIN EN 54, DIN VDE 0833-4 and DIN 14675 (voice alarm systems) do not apply to NIKOS, since they concern a different field of use and functional scope. As a public address system for temporary and mobile deployments, NIKOS has already been used successfully many times for mission-critical communication tasks since 2017. 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 communication platform. These savings can quickly offset the rental and installation costs of NIKOS. You can find some specific examples of potential 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. Especially for temporary, time-limited events, this significantly reduces the costs of planning, setting up and operating the safety technology.
Is NIKOS resilient in a crisis during the Long Night of Museums?+
Yes. NIKOS operates via its own autonomous radio network and is completely independent of public communication networks and their availability. Because NIKOS does not rely on wired connections but communicates via radio, the connection is automatically re-established after an interruption. NIKOS [audio]² has an internal battery with up to 16 hours of runtime, which also powers connected accessory modules. This means that emergency announcements for the Long Night of Museums remain reliably functional even in the event of a power failure or disruptions to public communication networks.
Can NIKOS be deployed at different museum venues at short notice?+
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 a few minutes and configure them individually. A standard Schuko power connection is sufficient for continuous operation. Where technically suitable, NIKOS uses an existing digital radio network.
