Abstract

A display device (40) for use with a passenger conveyor (20) provides a traffic flow direction indicator and visible maintenance information. One example includes a display panel (42) supported on a surface (38) that is conveniently positioned between a handrail (28) and a landing (24). In one example, a single display panel (42) alternatively provides the traffic flow direction indicator or the maintenance information. In another example a first display panel (42) and a second display panel (48) are supported on a plate (43) that is selectively moveable into different positions, depending on which display panel should be visible. One example includes a remote signaling device (62) that allows an individual to control the information shown on the display device (40).
