Typical Hazards

A fire is one of the most common and frequent hazards to human life and property. The greatest hazard is created in buildings where a great number of flammable materials are used and/or where buildings have rather complex interior layouts. The level of the risk can be considerably reduced by using an evacuation PA system.

The evacuation PA system is usually a modular system, most commonly consisting of an electric fire-alarm system and emergency voice evacuation system. Stringent technical requirements imposed on such systems are regulated by the national legislation and standards in the majority of countries. However, what has influenced the requirements even more than legal regulations or standards is individual customers’ demands. Customers do not seek a single-purpose system that is used during an emergency, but the most modern multi-purpose solution for the sound distribution throughout a venue or building that is adaptable exactly to their specific needs, complies with the requirements for PA systems, and that is easily connectable to and controllable and/or controlled by other SCADA systems at the same time. Thanks to such advantages customers can considerably save investment costs.

The interior and exterior sound distribution solution offered by the Telegrafia Company is based on the cutting-edge modular sound distribution, warning and evacuation technology of the Amadeo system, completely proven by years of operation and service in a number of plants and industrial sites in Slovakia and in the world.

PA system within a single building

This solution is suitable for premises where technical requirements for a sound distribution system can be satisfied by using the Amadeo central electronic unit. The premises are then divided into separate compartments or zones to which sound signal is transmitted selectively. One or more control stations, typically the OCP16 operational control panels, are connected to the central electronic unit. They ensure live and pre-recorded audio input from other sources, allow the activation of announcements and signals stored in the digital memory of the central electronic unit, and they control other connected devices.

A computer equipped with the Vektra® software can be connected to the Amadeo central electronic unit, thereby extending the system possibilities and functionalities. Normally, loudspeakers to distribute sound in the interior are connected to the central unit within the 100 V electrical circuit; however, the Amadeo technology allows sound distribution in extraordinarily noisy interiors or large open-air areas by means of more powerful siren pressure loudspeakers.

PA system within a set of buildings

This solution is based on the Amadeo technology. As it is necessary to distribute sound effectively from the Amadeo central electronic unit to a number of buildings, it is designed as a multi-level system with a local electronic unit in each building. Loudspeakers are connected to these local electronic units within the 100 V electric circuit and they can be arranged along the individual loops or zones on specific floors and/or in specific rooms.

Sound to remote and/or open-air areas within a complex of buildings is then additionally transmitted by powerful pressure loudspeakers or by the small multi-purpose Screamer or Bono sirens. Obviously, the system can be enhanced by connecting more powerful Pavian electronic sirens. The individual local electronic units can be hierarchically ordered and controlled from the Amadeo central electronic unit. They are interconnected by wire using the existing computer infrastructure and TCP/IP protocol or wirelessly via radio.

The effectiveness of the system and its functions can be maximised by adding other useful components such as sensors, various detectors of hazardous substances, beacons, strobe lights, cameras, etc. The Amadeo system, especially in combination with the Vektra® software, can be used to control other SCADA systems such as gates, ventilation technology, and various electromechanical regulators, or it can be extended with new functions, e.g. automated notification, summons or monitoring.

System Control

  • From the central building
    • Using the OCP16 operator’s control panels or LCU15 local control units.
    • Using the central computer equipped with the Vektra® software.
    • Using any computer in the building (equipped with the Vektra® software), connected by the Ethernet (TCP/IP) to the Amadeo central electronic unit.
  • From any building within a set of buildings
    • Using the OCP16 operator’s control panels or LCU15 local control units connected to local electronic units.
    • Using any computer in the building (equipped with the Vektra® software), connected by the Ethernet (TCP/IP) to the nearest local Amadeo electronic unit.
  • From the exterior
    • Using a mobile phone.
    • Using a conventional telephone line.
    • Using the Internet.
    • Using a radio station.
