Wiegand Connection
The Wiegand interface connects to the Avolution S-series control panel via the standard
keypad buss, using the POS, NEG, CLK & DAT connections (see board drawing below). The
board must also be set to a spare keypad address using the DIP Switches on-board. It is
important to set the Wiegand interface board to an unused keypad address otherwise buss
conflicts will occur. The keypad addressing is done as per the chart below.

DIP Switches 1-3 (Keypad Address)
In the drawing above the DIP Switches are indicating that the Wiegand Interface board is set
to keypad number 8 (Switches 1, 2 & 3 all OFF).
DIP Switch 4 (Presco Mode)
Presco mode is selected when Switch 4 is in the “ON” position. When Switch 4 is “OFF” the
board is in standard Wiegand mode. Note the board can accept up to a maximum of 9 digit
codes from the PRE/PSE keypad. Valid digits are 0-9. The * & # characters from the PRE
keypad are ignored by the Wiegand board. When Presco mode is selected the RED & GRN
LED’s and associated outputs are inverted to match the operation of the PRE & PSE
keypads.
Dallas I-Button Mode
Shorting inputs “L1” & “L0” together before powering up the board puts it into Dallas I-Button
mode.
Interface Board Zone Input
The terminals “IN1” and GND” (see “KP Buss & Zone Input” terminal block on figure 1) can
be used as a Zone input on the panel.
The zone input number is related to the keypad address set on the board.
For example;
If the keypad address was set to number 8 (as per figure 1), the zone input can be associated
with either zone 8 or zone 16.

Zone Number
The chart above lists the zones that can be associated with the board based on the keypad
address used.
For the interface board input to work as a zone it must be made active (P122E option 1 ON)
and assigned as a keypad zone (P122E option 4 ON).
When the zone is set as a keypad zone (P122E option 4 ON) the EOL settings at P125E and
the response times at P126E don’t apply.
When Option 2 at P122E is turned OFF (zone is normally closed), the zone input is sealed
when the “IN1” terminal is shorted to the “GND” terminal.
An open circuit between “IN1” & “GND” will result in the zone being unsealed at the panel.
If Option 2 is turned ON at P122E (zone is Normally Open) the zone input is sealed when it is
open circuit and unsealed when “IN1” is shorted to “GND”.
If you change the setting at P122E option 2 you may have to open and close the zone to
allow the panel to get in sync with the new state of the input.
Keypad Zone Program Summary
P122E Option 1 must be ON (zone is active)
P122E Option 4 must be ON (zone is a keypad zone)
P122E Option 2 OFF (zone is normally closed)
P122E Option 2 ON (zone is normally open)
NOTE: Option 5 at P122E must be off for the keypad zone to work (ie not set as a radio
zone).
Interface Board Relay Output
The Wiegand interface board is fitted with a relay that can be used to operate a door lock or
similar device. The relay contacts are available at the “Relay Output” terminals (see figure 1`)
on “NC1” (Normally Closed), “COM1” (Common) and “NO1” (Normally Open).
The relay will follow one of the outputs 1-8.
The output that the relay follows is related to the keypad address assigned to the Wiegand
board.
For example;
If the keypad address was set to number 8 (as per figure 1), the relay output will follow output
8 options. If the Wiegand board was set to keypad address 4 the output will follow the
options programmed for output 4.
Option 6 at P25E10E must be turned ON for the Wiegand output to work.
“RED” Output
On the Wiegand connector block there is a terminal labelled “RED”. There is also a
corresponding LED (red Led) on the board (see figure 1).
The “RED” output should be connected to the Red LED wire on the Wiegand reader (see
following wiring diagrams).
The RED output can indicate two things.
1- When the Avolution control panel is in program mode the RED output will repeatedly
flash out the keypad address number. This can be useful for determining the keypad
address assigned to the reader without having to look at the DIP Switches on the
Wiegand interface board (which may be installed out of view in a ceiling space or
some other inaccessible place).
2- The RED output can be programmed to follow the state of an output from 1-8. This can
be used to turn on the LED while an output is on (to show that the door has been
unlocked) or used to indicate the Arm/Disarm state at the reader, etc. Associating the
RED output with one of the panel outputs is done at location P98E.
“GRN” Output
On the Wiegand connector block there is a terminal labelled “GRN”. The terminal labelled
“GRN” and its associated on-board LED (see figure 1) will follow the buzzer output. This
allows an LED on a keypad or reader to be able to visibly indicate entry/exit beeps, alarm
beeps, etc.
BUZZER (“BUZ”) Output
The Buzzer (BUZ) output can be connected to the Buzzer wire on a reader if available.
The Buzzer output follows all of the programmed keypad beep options assigned to that
keypad number.
For example;
If the keypad address was set to number 8 (as per figure 1), the buzzer output will follow all of
the keypad beep options assigned to keypad 8.
The beep options include entry/exit beeps, alarm beeps, keypad acknowledge beeps (3 short
beeps) and keypad error beeps (one long beep).
INSTALLATION DETAILS
It is intended that the cabling distance between any keypad or reader connected to the
Wiegand interface board should be no more than 10m. The Wiegand board can be up to
100m away from the Avolution control panel.

For the PR-03 to work properly DIP Switch 4 must be OFF at power up and DIP Switches 1-3
should be set to an unused keypad address number.
While the panel is in program mode the on-board Red LED and the RED terminal will show
the keypad address as explained above.
By connecting the “RED” output on the Wiegand terminal block to the brown wire (LED-R) an
installer can view the interface board address from the PR-03 reader by simply putting the
control panel in program mode.
By connecting the Yellow (BEEP) wire to the “BUZ” output on the Wiegand terminal block the
internal PR-03 buzzer will follow all of the keypad beep options programmed at the panel for
that keypad number.
To program an access card/tag using the PR-03 reader the control panel must be in program

PRE & PSE Operation and programming
For the Presco PRE & PSE keypads to work properly DIP Switch 4 must be ON at power up
and DIP Switches 1-3 should be set to an unused keypad address number. By connecting
the Red PRE/PSE wire to the “RED” output on the Wiegand terminal block the RED LED on
the keypad can be controlled by the Wiegand board as per the PR-03 operation.
NOTE: The Red and Green LED’s on the PRE/PSE keypads are inverted to the normal prox
reader LED operation. When the Red LED on the PRE/PSE keypad is off the corresponding
Red LED on the wiegand board will be on. The same inversion applies to the Green LED.
This inversion happens automatically when the board is powered up with DIP Switch 4 ON.
When a code is entered at the PRE/PSE keypad it is sent to the panel as an access card/tag
code once the “E” button (PRE) or “#” button (PSE) is pressed. You can enter up to 9 digits at
the PRE/PSE keypad before pressing either the “E or #” button.
The following program addresses apply to the PRE/PSE-Wiegand Interface;
P21E 1-100E
Learn a card/tag as user 1-100
P22E 1-100E
Delete a card/tag user 1-100

P122E1-16E Opt.4 If option 4 is ON the wiegand input becomes a zone input (see
description of input above)
To learn a code as an access card/tag user (eg User 50) press P21E50E at a normal keypad
(that is in program mode) then go to the PRE/PSE keypad and enter in your 1-9 digit code
followed by the “E” or “#” button.

CODEGUARD Operation and programming
For the CODEGUARD keypad to work properly DIP Switch 4 must be OFF at power up and
DIP Switches 1-3 should be set to an unused keypad address number.
By connecting Pin 8 of the CODEGUARD to the “RED” output on the Wiegand terminal block
the RED LED at the bottom of the keypad can be controlled by the Wiegand board as per the
PR-03 operation.
Connecting Pin 6 of the CODEGUARD to the “BUZ” output the buzzer on the codeguard will
follow all of the keypad beep options programmed for that keypad number.
When a code is entered at the CODEGUARD keypad (by pressing “*”, “CODE”, “#”) it is sent
to the panel as an access card/tag code once the “#” button is pressed. The number of digits
you can enter is set by the Mode switch on the CODEGUARD keypad (see manufacturers
instructions for details). In general the default Mode 0 is the best setting as it allows for a
variable code length from 1-9 digits.
The following program addresses apply to the CODEGUARD-Wiegand Interface;
P21E 1-100E
Learn a card/tag as user 1-100
P22E 1-100E
