Wiegand Reader Connection
The following diagrams show the connection of a standard Wiegand reader with the reader expander controlling
an access door.
When using the standard Wiegand interface, two wiring methods can be used. Single LED operation allows a
single LED line to control both LED colors.

Dual LED operation allows the signaling of both LEDs independently using the LED control lines, and is ideal to
show the status of alarm or other integrated signals.
