Braille in National Aquatic Centre lifts

I was wondering about the Braille signs in the lifts at Dublin’s National Aquatic Centre, and it turns out they are in German (courtesy of the Wikipedia entries on German braille and Braille patterns in Unicode):

Open doors


⠞⠳⠗⠀⠡⠋
Tür auf

Close doors


⠞⠳⠗⠀⠵⠥
Tür zu

Alarm


⠝⠕⠞⠗⠥⠋
Notruf

Curious. See also this xkcd (thanks to Oliver Nash for the pointer).
