Introduction 1
Introduction
The Wiegand Interface Unit-Four State (WIU-4) board features a
Wiegand to F/2F data converter, which can accommodate both
conventional and proprietary Wiegand reader protocols, and
includes an 8 Amp relay for door strike control (entrance/exit)
activity. It provides the communications interface that enables
support of up to 16 Wiegand-output readers.
When combined with most conventional Proximity, Mifare®, and
ISO-15693 Wiegand-output readers, the WIU-4 reports
immediate alarm notification of short circuit, cut line, open
circuit, or closed circuit conditions to the GE access control
system.

Safety
Radio interference
Electrostatic discharge (ESD) precaution
WARNING: This is an FCC Class A product. In a domestic
environment, this product may cause radio
interference, in which case, the user may be
required to take adequate measures.
WARNING: Circuit board components are vulnerable to damage
by electrostatic discharge (ESD). ESD can cause
immediate or subtle damage to sensitive electronic
parts. An electrostatic charge can build up on the
human body and then discharge when you touch a
board. A discharge can be produced when walking
across a carpet and touching a board, for example.
Before handling any board, make sure you dissipate
your body’s charge by touching ground. This
discharges any static electricity build-up.

Maximum cabling distance
WIU-4 to micro:**
WIU-4 to reader:***
** WIU-4 to micro: The maximum cabling distance of 1,000 ft (304.8 meters) is
influenced by wire gauge, reader power requirements, and the 12 VDC level from
the microcontroller.
*** WIU-4 to reader: The maximum cabling distance of 250 ft (76.20 meters) is
influenced by wire gauge, reader power requirements, minimum input voltage at
the reader when using the 12 VDC from the WIU-4 (originally from the micro), and
the cabling between the WIU-4 and micro.
1000 ft (304.8 m) @ 12 VDC with 20 AWG cable
250 ft (76.2 m) @ 12 VDC with 20 AWG cable
Door strike relay****
**** The life of the relay decreases as the current switched by the contacts is
increased. Use low current door strikes for high traffic doors to maximize the
relay life. Use an external relay for high current applications.
