Abstract
A facility access system includes a system microprocessor and input and output subsystems. The input subsystem can include switching devices connected in a parallel configuration for actuating the system microprocessor in a sequencing mode of operation. Input devices are also disclosed which produce input signals corresponding to particular memory storage locations for accessing directional and other information in a look-up mode of operation. The directional and other information is output to text display, graphical display and audio output devices. A user's computer can be linked to the system microprocessor for downloading information therefrom. An emergency subsystem provides emergency exit information, dials out to summon assistance and includes a backup power source.
