Abstract
An elevator system which includes a display of dynamic system conditions, and a building floor security arrangement which cooperates with the elevator system and display to take cars in and out of service, and to selectively control access to the floors of the building. The display visually confirms each change correctly initiated by the security arrangement. Multiple display modes may be selectively activated to either decode an input to the display and display an associated legend, or to examine the integrity of the wiring associated with the input.
