The Memco elite 674 safety system has 2 independent detection systems. The first is a light-curtain of infra-red beams operating between the lift car doors. The second is a '3D' system of proximity detection operating in the landing zone. Any person or object breaking the light-curtain, or detected within the '3D' zone, will trigger the system and reopen the doors.

The 674 safety system consists of a transmitter detector (TX) and a receiver detector (RX) mounted on the car doors. Each detector is housed in a robust profile only 9.8mm wide. The 674 will automatically sense the door separation and adjust itself for optimum performance.

In many installations a separate controller is unnecessary and the detectors can be connected direct to the door controller or lift operator.
