Abstract
An elevator system (20) includes a transceiver (22) that receives at least one wirelessly transmitted signal (24). In one example, a signaling device (26) includes a plurality of switches (28) that can be activated to provide a signal indicating a desired or intended destination. The signal also provides an indication of the individual from whom the signal is received. A system controller (30) responds to the signal by assigning an elevator car (32) to travel to the intended destination. When the elevator car (32) is situated to receive the individual, in the event that another wireless signal is received, the system provides at least one access feature including delaying closing an elevator car door or generating an audible sound to guide the individual to the car. In one example, the system maintains information regarding expected locations of individuals providing such signals to facilitate providing assistance to them for exiting a building, for example.
