NIKOS – CHIO Aachen – Pferdesport

Voice Alarm for CHIO Aachen

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 safety announcements in noisy spectator areas

At CHIO Aachen, packed grandstands, changing visitor flows and the noise of an international equestrian event come together. In a hazardous situation, safety announcements must be clearly understood by spectators, participants and operations staff, without any individual areas being reached with delay.

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 [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 makes it possible to broadcast announcements specifically to individual areas, multiple locations or the entire venue.

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.
How can specific visitor areas at CHIO Aachen be addressed selectively?+
NIKOS [dispatcher]² controls the announcement units as required for individual announcement locations, specific areas or the entire venue. This makes it possible to address areas where visitors need to be guided or informed, without every announcement necessarily being broadcast at all locations.
Is NIKOS resilient in a crisis?+
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. Since NIKOS does not rely on cable connections but communicates via radio, the connection is automatically restored after an interruption. NIKOS is therefore much more resilient to disruptions of normal operations than many other systems and demonstrates the crisis resilience of this communication system. NIKOS [audio]² has an internal battery with up to 16 hours of operating time and also supplies connected accessory modules via the battery. Even if the mobile network is overloaded, the internet provider has been hacked or someone has unplugged the wrong cable, NIKOS continues to operate. This means that voice alarm at CHIO Aachen remains reliably functional even in the event of a power failure or disruptions to public communication networks.
Can NIKOS be deployed quickly and flexibly?+
Yes. NIKOS was specifically developed for flexible outdoor deployments without fixed infrastructure. The modules can be mounted by one or two people within a few minutes on different structures such as lampposts, stages, stands or trees, and configured individually. A standard Schuko power outlet is sufficient for continuous operation. Where the technical specifications permit, NIKOS uses a digital radio network.
Voice Alarm for CHIO Aachen: Where can NIKOS be rented?+
