Bus Intercom System


Primary benefits:

  • European certification EMC-R10 for installation in vehicles
  • Improves bus accessibility - enables quality communication between the driver and rear passenger (mothers with baby carriages, disabled people or passengers with special needs who are boarding / sitting at the back of the bus)
  • Option for parallel connection of 2 rear-talk stations (for long articulated bus)
  • Dedicated use for a bus - 12V / 24V direct operating voltage
  • Easy for use and operation

Intervox Intercom bus system was developed specifically for buses to meet the accessibility requirements of people with disabilities in public transportation.

The system meets the stringent EMC-R10 standard requirements for installation.

This is an anti-vandal system dedicated to buses that allows communication between the driver and passengers with special needs coming from the back door and / or sitting in a dedicated seat at the back of the bus. (Mothers with baby carriages, wheelchair-bound people, adult passengers coming from the back door, etc.).

The system enables you to make a proactive contact with the driver and a qualitative two-way conversation when necessary. In addition, the system is suitable for long articulated buses where there is a problem to contact the driver from the rear.
