Simple System Configuration
The basic system
configuration would be one controller
and one card reader. The card
reader and door controls would, of
course, be located at the point of
entry. Cabling between the card
reader and the controller allows data
to be sent to the controller and status
information to be sent back to the
reader indicator lights. Additional
cabling allows for the control of a
door release and a sensor signal to
be sent to the controller when the
door is opened. A manual access
switch can be added to the system so
that personnel without cards may be
visually recognized and the door
opened for them. The processor
board provides the surge protection
necessary to protect the CPU in the
event that the reader receives a
surge.
Most installations will consist of at

least two entry points controlled by
one primary controller. For systems with more than two points of entry, multiple controllers are
connected in a loop configuration with one controller acting as the primary unit and the others as
