NIKOS – Landesfest

Emergency Announcement for Hessentag 2027 in Idstein

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

Clear warnings despite network failure

At Hessentag 2027 in Idstein, emergency announcements must remain quick and clearly understandable even when visitor numbers are high. Background noise, crowds and the uneven distribution of visitors make it more difficult to communicate warnings and instructions safely. At the same time, the mobile network may be restricted due to heavy demand.

Solution

One unified solution for everyday use and emergencies

Announcements, system monitoring, crowd management and device control come together with NIKOS in a single platform independent of the public network. NIKOS [audio]² delivers emergency announcements through the designated announcement units and remains operational during a power failure thanks to its internal battery. The reduced need for separate loudspeaker, control and communication solutions lowers the effort required for materials, installation and support.

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 NIKOS's wide range of functions and support you in implementing the requirements cost-effectively.
Will emergency announcements for Hessentag 2027 work even in the event of a power or network failure?+
Yes, NIKOS operates via its own autonomous radio network and is completely independent of public communication networks and their availability. This makes the system highly resistant to external influences. Because NIKOS does not depend on wired connections but communicates via radio, the connection is automatically re-established after an interruption. NIKOS therefore responds much more resiliently to disruptions in normal operations than many other systems, demonstrating the crisis resilience of this communication system. NIKOS [audio]² has an internal battery with a runtime of up to 16 hours and also powers connected accessory modules. Even if the mobile network is overloaded, the internet provider has been hacked or someone has pulled the wrong plug, NIKOS continues to operate. This means that emergency announcements for Hessentag 2027 remain reliably functional even if the power supply fails or public communication networks are disrupted.
Can NIKOS be installed at short notice for Hessentag 2027 in Idstein?+
Yes, NIKOS was specifically developed for flexible outdoor deployments without fixed infrastructure. The modules can be mounted and individually configured by one or two people within just a few minutes on various structures such as streetlights, stages, stalls or trees. A standard Schuko power connection is sufficient for continuous operation. NIKOS uses an existing digital radio network.
How can emergency announcements at Hessentag 2027 be directed to specific areas?+
NIKOS [dispatcher]² controls the announcement units for individual announcement locations, specific areas or the entire site. This allows emergency announcements to be transmitted to selected areas according to the situation or simultaneously to all designated locations.
Where can an emergency announcement system for Hessentag 2027 in Idstein be rented?+
