PA/VA SOLUTIONS FOR STRATEGIC FACILITIES (SAFETY AND SECURITY)

Industrial facilities such as power stations, chemical plants, refineries etc. require particularly reliable systems and therefore MULTIVES PA/VA system offers enhanced safety measures to fully comply with such requirements:
• Use of fibre-optic loops between central units guarantees that in the event of a single fault/damage, the system will continue to function properly

• Even a total loss of connectivity affecting a part of the system will not reduce the overall system functionality – individual units will continue to operate independently and transmit messages warning of emergency

• Connecting fireman microphones into the fibre-optic loop allows transmitting audio messages to any part of the system in the event of a single damage to microphone cabling

• Damage to messaging memory of a specific unit results in transmitting of messages automatically uploaded from the memory of other units

• Loudspeaker lines utilised in open spaces are connected to central equipment via certified surge protectors to ensure safety against power surges caused by lightning

  • 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.
