Solution description

This solution is based on the Amadeo technology. The core is formed by the Amadeo central electronic unit situated in the interior (at a reception, management office, local government office, etc.). Control stations, typically the OCP16 operational control panels or LCU15 local control units, 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. A computer equipped with the Vektra® software can be connected to the Amadeo central electronic unit, thereby enhancing the standard of users’ comfort.

To distribute sound to a number of areas in the exterior (such as car parks, adjacent areas, etc.), the PA system is designed as a multi-level system with a local electronic unit in each building. Single electronic units are linked by wire through the existing computer network infrastructure using the TCP/IP protocol, or wirelessly via radio. They can be hierarchically ordered and controlled from the main control centre.

The PA system can be interconnected with a fire-alarm sensor grid system and also integrated within the superior national early warning and emergency notification system.

System structure

  • the Amadeo central electronic unit
  • the OCP16 operator’s control panels or LCU15 local control units
  • electroacoustic transducers
    • loudspeakers (wall, ceiling, pendant or ball-shaped types) for 100 V lines
    • aluminium-alloy horns with powerful pressure loudspeakers
  • a computer equipped with the Vektra® software

Where and why to use a combined PA system

Where to use a combined PA system

  • Sport facilities (stadiums, swimming pools, football fields, aquaparks, etc.), ZOOs, entertainment facilities, etc.
  • Universities and campuses.
  • Hospitals, spas and wellness centres.

Why to go for this solution

  • To transmit intelligible acoustic messages to a relatively larger area (both the interior and the exterior) from a single point.
  • To distribute sound in buildings with noisy operations, where, for various reasons, warning notifications coming from the exterior are not audible.
  • To inform the occupants by live voice announcements, to reproduce music, jingles, etc.
  • To use the PA system in emergency situations for the purposes of guided evacuation, in addition its daily commercial use.
  • To test the system on a regular basis, if required, and to minimise the probability of failure occurrence during its operation in emergency situations.
  • To guarantee the system operability in case of power failure.

System Control

    • From the interior
      • Using the OCP16 operational control panels or LCU15 local control units.
      • Using the central computer equipped with the Vektra® software.
    • From the exterior
      • Using a mobile phone.
      • Using a conventional telephone line.
      • Using the Internet.
      • Using a radio station.

Advantages

  • Intelligible announcements even in the acoustically isolated building interiors.
  • Messages delivered to selected zones within the entire building.
  • Various methods of the system control from either the interior or the exterior.
  • The pre-programming and planning of announcements.
  • Advanced autodiagnostic functions with the precise failure location in the system (or the location of the defective loop in the 100 V line).
  • Real time information about the entire system status and the statuses of individual devices.
  • The system independence – in case a failure occurs at one end point within the system, other end points or components remain fully operational.
  • The selection of individual announcements targeted towards specific zones within the area, as small as the individual end points or loops.
  • The application of the PA system as a local warning system in emergency situations.
  • The possibility of the evacuation of civilians from the area by the timely and direct intervention in the system from the exterior.
  • The connection of the PA system with a national or regional early warning system, or with an autonomous local early warning system in emergency situations.
  • Full functioning of the system for several hours even after power failure.

Disadvantages

  • Higher investment costs in case of the installation of several local central units.
