A monitoring device for use in a passenger conveyor system includes an indicator operable to indicate a need for a maintenance action in response to a control signal. Operation of the indicator relies on an electronic memory device. The electronic memory device is included in a separate component of the passenger conveyor system. A method for installing the monitoring device includes: (1) providing the monitoring device; (2) mounting the mounting device at a position within the passenger conveyor system such that the mounting device is easily accessible to a user; and (3) connecting the monitoring device to the separate component of the passenger conveyor system to permit communication there between.
