EAO – Series 57 Multi-Tone Warning Indicator
Compact, intuitive and safe. The Series 57 MTWI uniquely combines two rail industry established HMI functions into one singular compact device – the Series 56 multi-tone sound module and the Series 57 warning indicator.
This provides additional advantages and enhances safety in public transportation, especially for people with visual impairments. Passengers are intuitively warned about potential dangers thanks to the loud, audible warning signal and the LED status indicator visible from any angle.
