The Memco elite Model 633 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 dense beam pattern will pick up even very small objects between the car doors.

The 633 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.
