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.

** 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.

Installation overview
The following is the general sequence of steps to follow when
installing the Wiegand Interface Unit-4. Each step is explained in
further detail in the sections that follow:
1. Mount the WIU-4.
Refer to “Mounting the WIU-4” on page 7.
Note: The WIU-4 must be mounted indoors, in a protective enclosure or
standard 2-gang electrical box (Installer supplied) as shown in
Figure 1.
2. Configure the WIU-4.
Refer to “Configuring the WIU-4” on page 8.
3. Connect the WIU-4.
Refer to “Connecting the WIU-4” on page 14.
4. Test the WIU-4.
Refer to “Testing the WIU-4” on page 17.

Mounting the WIU-4 7
Mounting the WIU-4
Figure 1. Mounting instructions
1. To mount the WIU-4 board in the 2 gang electrical box,
remove the electrical box cover and clean it with the
alcohol wipes provided in the mounting hardware kit.
2. Apply the four standoffs, provided in the mounting
hardware kit, to the four corners of the WIU-4 board, as
shown in Figure 1.
3. Remove the adhesive liner on the standoffs and attach the
WIU-4 board to the electrical box cover, making sure the
WIU-4 board does not interfere with or touch the sides of
the electrical box.

Configuring the WIU-4
The WIU-4 has the following connectors and jumpers:
•J3: Door and REX switch connector
•J4: Four state door supervision jumper (Enabled)
•J5: Reserved. (A jumper must be installed on pins 1
and 2)
•J6: Reader interface connector
•J7: Reserved
•J8: Micro interface connector
•J9: Reserved
•J10: Door strike relay connector

J3: Door and REX switch connector
The 6-pin connector, J3, is the door and REX switch interface.
If the door or REX switch is set up as supervised (1K resistor in
series with switch between high and return pins, 1K in parallel
with switch), the WIU-4 treats both the door and REX switch as
supervised and reports four states: cut line, short circuit, closed
circuit, and open circuit.
Note: To enable four-state supervision for the door and the REX, install a
jumper at position J4. Both points must be terminated with
resistors as shown in Figure 4 on page 15.
If supervision is required for only one (the door or the REX), then
also insert a 1K resistor across J3, pins 3 and 4 or pins 5 and 6, as
applicable.
If the door or REX is not set as supervised, the adapter reports
two states: open when there is no connection between the high
and return pins, or closed when a short exists between high and
return pins.
J4: Door and REX supervision connector
The 2-pin connector, J4, is the door and REX supervision
connector. By default, a jumper is installed on pins 1 and 2 to
enable 4-state supervision. Remove the jumper to disable 4-state
supervision and enable 2-state supervision.

J5: Reserved
The 3-pin connector, J5, is reserved. A jumper must be installed
across pins 1 and 2.
J6: Reader interface connector
The 10-pin connector, J6, is the reader interface connector.
If a tamper switch is desired, connect a single-pole, single-throw
(SPST), normally-closed pushbutton switch (installer supplied) to
connector J6, pins 8 and 9 on the WIU-4. When used with a
Micro/5-PX, Micro/5-PXN, M5PXNplus, Micro/PX-2000,
Micro/PXN-2000, M2000PXNplus, or M3000PXNplus, the
WIU-4 sends a supervised reader alarm message.
