7-segment display

7S2R is a microcontroller based 7-segment display device for lifts. It can be assembled either to the car or to a level. 7S2R accepts a wide range of nominal supply voltages; this is possible because it is equipped with high efficiency on board switched mode power supply (SMPS). 3-tone gong sound generator produces different sound depending on direction.
