SOLUTIONS FOR AIRPORTS

The main purpose of the voice alarm system (VA) is to effectively warn the public of eminent danger thus allowing efficient evacuation. The warning and informative functions can be triggered automatically via the fire alarm system or manually using fireman microphones. The audible alarm system is designed to cover all areas of a building to reach its occupants in the event of an emergency.

More importantly, MULTIVES PA/VA system can be successfully used to fulfil non-emergency functions i.e. it can provide standard public address system  (PA) functionality. Thanks to its excellent audio setup, in normal conditions it can be used to address public for specific announcements (using either zone microphones or external sound sources) and/or to provide background music.

Key characteristics and functions of MULTIVES PA/VA system to be taken into consideration when planning and installing voice evacuation system in various buildings and venues:

• Zone microphones ABT-DMS can be installed at information points and check-in zones to allow airport staff to make public announcements to passengers awaiting departure. Thanks to TCP/IP protocols and Ethernet switches used to connect up to 263 microphones, our system is capable of supporting applications even at the busiest airports.

• The system offers in-built DSP processors enabling correction of audio signals at each entry and exit level. Our ABT-LA line speakers offer significantly farther reach while maintaining highly-balanced sound levels. Both elements guarantee the highest level of clarity of announcements, even in areas of poor acoustics such as busy Arrivals and Departures halls.

  • Compliance with EN 54-16, EN54-4

  • up to 44 loudspeaker lines per Control Unit

  • Ability to simultaneously broadcasting nx 11 messages (n-number of CU)

  • Total amplifiers power of 1300 W

  • Cooperation with zone microphone ABT-DMS and ABT-M0x

  • TCP/IP network architecture

  • Up to 254 devices in the network with copper or fibre-optic wiring connection

MULTIVES FLEXIBLE TOPOLOGY

The main role of Voice Alarm System is the implementation of essential evacuation functions and communication of a threat occurrence. In normal conditions, Voice Alarm System fulfils the role of Public Address System and is able to broadcast music or public announcements using zone microphone or other connected to the system source of sound. Public Adress system for transport infrastructure enables broadcast of messages to selected platforms or other infrastructure of the train station in order to inform waiting passengers about any changes to the train schedule or any potential threat.

Integrated audio inputs in each Control Unit and each microphone allow connection of external sound sources and transmission of messages emanating from precedent external communication system.

Integrated message buffering function enables recording higher priority messages, broadcasting them through already engaged, by superior sources, loudspeakers and automatically playing them once the line becomes free.
