INTRODUCTION
The Memco élite 618 safety system provides
a light curtain of infra-red beams operating
between the lift car doors. Any person or
object breaking the beams will trigger the
system and re-open the doors. The beam
pattern will pick up even small objects
between the car doors.
The 618 safety system consists of a transmitter
detector (TX) and a receiver detector (RX)
mounted on the car doors. The system will
automatically sense the door separation and
adjust itself for optimum performance. No
setting up is required.
In many installations a separate controller is
unnecessary and the detectors can be
connected direct to the lift controller or door
operator.
