Introduction
The Wiegand Interface Unit - Two State (WIU-2) board is
installed between a GE controller and an access control reader.
When users present their credential (card, key fob, fingerprint,
etc.) to the reader, the WIU-2 converts Wiegand badge
identification (BID) data into the GE F/2F protocol and sends it to
the controller. The GE access control system then grants or denies
access to the secure location.
The Wiegand Interface Unit-Two State (WIU-2) board features a
Wiegand data converter, which can accommodate both
conventional and proprietary Wiegand reader protocols, and
includes a 2 Amp relay for door strike control (entrance/exit)
activity. With the WIU-2 card, any organization can quickly add a
wide range of Magnetic Stripe, Wiegand, Proximity, Mifare
®
,
and Biometric readers to any GE access control system.
To minimize installation efforts, the door contact and request-to-
exit (REX) input circuitry connects directly to the WIU-2 to
avoid the high cost of home-running cables back to the controller.
