Abstract: A building management system of an occupiable structure with an elevator system includes an elevator video display, a building computing device and a building status system. The building computing device includes a computer processor and a computer readable storage medium. The building status system is configured to send real-time building condition signals to the building computing device, and the building status system is configured to process the real-time building condition signals and output an associated information signal for display on the elevator video display.

Abstract: Passive infrared detectors (20, 22, 24, 26, 28) carried by an elevator car (14) detect the presence of persons on top of or in the hoistway (12) below the elevator car (14). The passive infrared detectors (20, 22, 24, 26, 28) can also be used to detect open landing doors with no elevator present.

Abstract: An elevator (9) includes remote elevator monitoring equipment (10) connected by a communication linkage (12) to a central elevator monitoring and control station (11). Main, drive, and door controllers (16-18) are interconnected (19-21) with the monitor lines. Power-on-reset (POR) of controllers may be caused internally or by remotely-operable power relays (23-25) which interrupt power to the controllers. Maintenance personnel at the remote station (11) may order a POR through the communication linkage. In another embodiment, the remote elevator monitor (10) determines presence of a malfunction which a POR may cure and causes a POR internally or by a power relay. In another embodiment, the controller (16a) includes, in its program routines, elevator diagnostics (50) which can recognize an elevator malfunction which a POR may cure, and either cause the relay to interrupt power for an interval or cause an internal POR.
