Abstract
An elevator system having at least two elevators, wherein at least one of the elevators is designated as an emergency personnel elevator, can be operated to allow a firefighter to commandeer a second elevator for the purpose of ferrying persons to a safe evacuation floor. The elevator system is configured to determine if a request for an evacuation elevator originates from the firefighter elevator car positioned at one of several floors of a building. In response to the request, an elevator car other than the emergency personnel elevator car is designated as the evacuation elevator car. Further, the evacuation elevator car is dispatched to the floor the emergency personnel elevator car is positioned, and the evacuation elevator car is dispatched to a predefined evacuation floor upon receipt of an evacuation request made by the firefighter.
