GY and GY20 - Signal light in the bottom mat

Alternating red / green circuit

There is a red/green light changing LED tube beneath the bottom mat, through a gap in the bottom mat, which is covered by acrylic glass. Our system watches out the up and down movement for escalators with bidirectional running direction and blocks the passengers in the opposite direction, with indicating a red light, or in case the escalator is free, a green light will be shown.
