Abstract
An elevator rescue system provides rescue signals from a remote control station. The rescue signals typically operate a release mechanism such as the brake to allow the elevator to move to an appropriate door zone. The rescue signals are preferably sent from a remote control station such as may typically monitor a number of elevators. Essentially, the rescue signal is initiated when the remote control station receives a signal from the elevator monitoring system that a particular elevator is likely to have trapped passengers. As an initial step, the remote control station ensures there is no safety reason not to move the elevator, and then remotely commands operation of an elevator component that allows the elevator cab to move.
