Abstract: Disclosed is an elevator system for a multilevel architectural structure, the system having: a system controller, an elevator and an elevator controller, wherein the system controller and elevator controller communicate over a network, multi-level hoistway in which the elevator travels, the multi-level hoistway including a plurality of egress levels, including a first egress level, the first level being a primary egress level, wherein during an alarm condition the system, when the primary level is inaccessible, performs an emergency assessment of identifying a safe level of the plurality of levels at which to discharge passengers, the assessment comprising obtaining a smoke density profile for the egress levels, the profile illustrating a distribution of smoke within the multilevel structure, analyzing the smoke density profile, identifying a safe level having a smoke density that is safe, and instructing the elevator to discharge passengers on the safe level.

Abstract: Disclosed is an elevator system having a first sensor in communication with an elevator in a multi-level hoistway, wherein during an emergency the elevator instructs the first sensor to sense conditions and transmit sensor data representing the sensed conditions, and the transmitted sensor data is processed to obtain an image representing an intensity of hazard conditions on at least a subset of levels serviced by the multilevel hoistway.
