Announcement technology NATURAL BT800

Designed as a compact 19″ built-in or stand-alone device, the bustec BT800 integrates seamlessly into any bus or train for passenger announcements. Its robust, maintenance-free construction and ample flash storage ensure uninterrupted operation and reliable message playback. Operators enjoy intuitive control through the vehicle’s on-board computer or a dedicated control unit, reducing driver workload and speeding up content updates. Optimized for both urban and regional services, the BT800 can function as an MCU central unit, streaming HD-quality audio announcements to TFT or LCD info displays via DVI. The device’s uncomplicated handling and simple integration enable transport operators to deploy and manage announcement content rapidly and efficiently.

  • Equipped with 32–64 MB of flash memory, the BT800 outputs 2×25 W for internal and 1×25 W for external or driver-cab speakers. It supports IBIS VDV 300, RS485, Ethernet (10/1000 Mbit), four digital inputs/outputs and an analog microphone input. Housed in an aluminium front panel with a RAL 9005 body, it meets Bus EMC Directive 2006/28/EC and Railway EMC Directive EN 50155. Operating on 24 V DC (± 30 %) with a maximum draw of 1.5 A, it delivers digital announcements at 11–44 kHz bandwidth and 8–128 kbit/s. Control and data updates are handled via the on-board computer or a dedicated unit using the VISE Windows editor.
The bustec BT800 delivers crystal-clear, maintenance-free voice announcements via USB/Ethernet, greatly enhancing accessibility for visually impaired passengers.
