NIKOS – Kirchentag

Evacuation announcements for Kirchentag 2027 in Düsseldorf

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

warn and guide different venues simultaneously

At Kirchentag 2027 in Düsseldorf, visitors, contributors and response teams are spread across various venues throughout the city. An evacuation announcement therefore has to be clearly understood not only at one central location, but at several venues at the same time. The dignified setting requires unobtrusive coordination, yet immediate and unambiguous instructions in an emergency. With large crowds and high-ranking guests, fast, reliable warning and targeted guidance are essential.

Solution

One unified solution for everyday use and emergencies

For events such as Kirchentag 2027 in Düsseldorf, NIKOS combines announcements, alerting, information messages, remote control and status monitoring in one platform. The system ensures information delivery even during power failures or disruptions to public communication networks. Central operation via NIKOS [dispatcher]² reduces operator routes, separate control devices and coordination effort between different venues. By combining several control and monitoring functions in one platform, the need for separate loudspeaker systems, dedicated control units and specialist staff for installing and supervising different subsystems is reduced. This reduces material, installation and operating effort while announcements, alerting and status monitoring remain within a clear system architecture.

FAQ

Information for planners and organisers

Do announcements with NIKOS comply with the applicable standards?+
Yes. NIKOS meets the requirements of DIN EN 50849 (electroacoustic emergency warning systems). NIKOS was developed specifically for safety-relevant announcement and alerting applications and is technically designed for use in everyday operations and emergency situations. For electroacoustic emergency warning systems, DIN EN 50849 is the relevant reference framework. The requirements stated there are fully met by NIKOS – unlike mobile-network-based systems – because there is no dependency on an external network, ensuring immediate availability at all times. Other standards known from safety technology, such as DIN EN 54, DIN VDE 0833-4 and DIN 14675 for voice alarm systems, do not apply to the field of use and functional scope of NIKOS and are therefore not relevant for approval. NIKOS is an announcement system for temporary and mobile applications and has been used successfully since 2017 to implement mission-critical communication tasks. RADACOM and your regional NIKOS partner will advise you on the wide range of NIKOS functions and support you in implementing the requirements cost-efficiently.
How can different visitor areas at the Kirchentag be evacuated in a targeted way?+
NIKOS [dispatcher]² addresses individual announcement locations, targeted areas or all connected venues. NIKOS [audio]² receives the voice transmission by radio on site and outputs it as an analogue audio signal. At positions without an existing sound system, NIKOS [horn]² adds acoustic output.
Does the evacuation announcement remain operational if power or public networks fail?+
Yes. NIKOS operates via its own autonomous radio network and is fully independent of public communication networks and their availability. NIKOS [audio]² has an internal battery with up to 16 hours of runtime and also supplies connected accessory modules. Even if the mobile network is overloaded or the power supply fails, evacuation announcements for the Kirchentag remain reliably operational.
How quickly can NIKOS be installed at different Kirchentag venues?+
NIKOS was developed specifically for flexible outdoor deployments without fixed infrastructure. The modules can be mounted and individually configured by one or two people within a few minutes on different structures such as lampposts, stages, stands or trees. A standard Schuko power connection is sufficient for continuous operation. NIKOS can use an existing digital radio network.
