Abstract
A particular elevator (1-9) is commandeered to transfer an emergency cab F to (or near) a floor where an alarm has been sounded. The commandeered car is brought to the floor FF where the emergency cab is parked. The fire cab is exchanged for the normal cab C on the commandeered car, and is then carried to (or near) the alarm floor for responding to the alarm. Passengers in the normal cab may exit through landing doorways (23). Emergency personnel have access to the alarm area through emergency hoistway doors (27). A rack and pinion horizontal motive means for moving the cabs is illustrated (FIG. 12 ).
