A roll-up safety device prevents accompanying persons from being pulled into the grille while it is moving upwards. For this reason, self-standing internal and external through beam photoelectric switches are installed in front of the grille curtain. These consist of transmitters and receivers. If the light beam is interrupted, the controls immediately stop the door moving.
A reflective photoelectric switch in the lower gate area (300 mm) detects people lying on the floor, vehicles and other objects. It ensures that the gate does not travel downwards in the first place, if the light beam is interrupted. A second photoelectric switch at approx. 800 mm height is recommended for gate systems used by trucks, SUVs etc.
