OSSDs
Override with automatic restart function, allows to restart automatically the normal
working of the curtain (normal operation condition) when the detection area (curtains +
sensors) is cleared.

all control operations must be assigned only to a well-trained and skilled personnel;
•
the user assigned to the actuation of the override function, must be able to work in a
condition of maximum surveillance and visibility of the whole area.
