GENREAL
480 entry codes, from 1 to 6 digits in length, can be pro-
grammed. They can activate either, or both of the relay
outputs. Relay #1 has a 5 Amp capacity. Relay #2 has a
1 Amp capacity.
Two LED indicators show the status of the entry system.
The left LED lights red to indicate power, then turns
green when access is granted. The right LED lights yel-
low when the keypad is in "lockout" condition (from too
many incorrect code entries). The keypad's courtesy light
illuminates the keys for two minutes after any key is
pressed. An internal sounder beeps when each key is
pressed.
The DOOR SENSE/INHIBIT RELAY #1 input can be
used two ways. If used for "door position switch", the
switch on the door detects forced entry or door ajar situa-
tions. If used for "inhibit/disable", the input can be wired
to a "service" switch or automatic timer that will disable
the Relay #1 when required.
REQUEST-TO-ENTER/EXIT input can be wired to a
pushbutton or fire access keyswitch to provide codeless
entry for authorized personnel. In a door control applica-
tion, this input is also known as a request-to-exit. The
"anti-passback" feature prevents using the same code
twice before the programmed time elapses.
The ALARM SHUNT output activates when access is
granted. This output can be wired to shunt alarm con-
tacts on the access door/gate to prevent triggering of an
alarm when authorized access occurs.
Two solid state outputs, capable of switching 100 mA to
common, are programmable to signal forced entry, door
ajar, lockout, alarm circuit shunting, request-to-enter/exit
and keypad active conditions.
The AC-225 is powered from a 12-24 Volt AC or DC
source. Power can be obtained from the access device
or a separate power supply. The EEPROM memory
retains all entry codes and programming, even without
power.

INSTALLATION
To avoid damage to the unit from static discharges, con-
nect the EARTH GROUND terminal to a good earth-
grounding point. Suggested wiring size is 18 AWG for
earth ground and for power, up to 500ft. (use larger wire
for longer runs). Use22 AWG or larger (depending on the
load) for all other connections.
CAUTION: Do not ground either side of the power
inputs when using AC power.
Select a location for the keypad. For door access control
installations, mount the keypad near the controlled door.
For gate control installations, mount the keypad in clear
view of the gate, but far enough from the gate so the user
cannot touch the gate from the keypad.
WARNING: TO AVOID SERIOUS INJURY OR DEATH,
MAKE SURE THAT THE UNIT IS FAR ENOUGH FROM
THE GATE SO THAT THE USER CANNOT TOUCH
THE GATE WHILE OPERATING THE KEYPAD. HOW-
EVER, THE GATE MUST BE FULLY VISIBLE FROM
THE KEYPAD.
MOUNTING
The AC-225 keypad can be mounted directly to a wall or
flat surface. Use the appropriate fasteners to secure the
keypad's backplate to the mounting surface. When
mounting the keypad to a concrete wall, use concrete
wedge anchors or molly anchors.
EXPOSED MOUNTING
The AC-225 keypad can be mounted on a standard
pedestal or exterior frame assembly. Use four security
bolts and locking nuts to secure the keypad’s backplate to
the pedestal or exterior frame assembly.

BASIC PROGRAMMING
When the AC-225 is in programming mode, both LEDs
will turn off until programming begins. After a program-
ming option number is entered the yellow LED will blink.
This indicates that the AC-225 is ready to accept the new
programming data. After the new data entry is complete,
the green LED will light while the data is being stored.
The red LED will light if any programming data is entered
incorrectly, and the command will have to be fully re-
entered. In the following programming instructions, the
characters "X" or "Y" represent the programming data to
be entered while the unit is in programming mode. The
possible values for "X" or "Y" along with the factory
default for the value is listed with each programming
option.
Entering Programming Mode
The Master Programming Code (default = 123456) is
used to enter Programming Mode.
Press: # 9 # X
X= the current 6-digit Master Programming Code
Exiting Programming Mode
Press: * * #
The red LED will light when Programming Mode is exited.
NOTE: The AC-225 will automatically exit Programming
Mode after two minutes of inactivity.
Re-entering a Command After a Mistake
If the red LED lights, indicating an incorrect entry, or a
wrong key is pressed during programming, to clear the
keypad and re-enter the command:
Press: * 9 #
Setting Entry Code Length Default: 4 digits
Press: 0 3 # X #
X = 1 - 6 for entry code length
NOTE: If the Entry Code Length is going to be changed
from the factory default of four digits, make this change
first, before programming any entry codes.
Adding a New Entry Code
Press: 0 1 # X # X # Y #
X = The new entry code:
1-999999, depending on code length
Y = Relay output entry code will activate:
1 = Relay #1 2 = Relay #2
3 = Both Relays 0 = No Relays
The yellow LED will flash quickly while the AC-225
searches its memory for available space and duplicate
entries. The green LED will light when the new code is
stored.
If the new entry code chosen is already being used for
another entry code, the red LED will light. A new unique
code needs to be entered.
NOTE: Leading zeros (zeros before the code number, i.e.
0001) do not need to be entered when programming a
new entry code. The Entry Check will internally add any
zeros to fill all digits determined by the entry code length
setting. Leading zeros will have to be entered by the user
when entering their code to gain access.
Erasing a Single Entry Code
Press: 0 2 # X # X #
X = The entry code to delete.
The yellow LED will flash quickly while the AC-225
searches its memory for the code to erase. The green
LED will light when the code is erased.
Erasing All Entry Codes
WARNING: Performing this command will remove all
entry codes from the memory.
Press: 9 7 # 0 0 0 0 0 0 # 0 0 0 0 0 0 #
NOTE: The green LED will light while the memory is
being erased. This may take up to 15 seconds.
Changing the Master Programming Code
Press: 9 8 # X # X #
X = The new 6-digit Master Programming Code

PROGRAMMING OPTIONS
There are several AC-225 programming options. For
most installations, the factory set default options are
sufficient. The keypad must be in programming
mode to make these change.

X = 0 for Door Sense, 1 for Inhibit
When programmed for DOOR SENSE (door position), if
an open condition on the input occurs before access is
granted (with an entry code or with the request-to-enter
input) a FORCED ENTRY output will occur. If an open
condition remains 60 seconds after a relay activation for
access, a DOOR AJAR output will occur.
When programmed for INHIBIT(disable), a closed con-
dition on the input will prevent relay #1 from activating
when access is requested (with an entry code). This
mode is typically used with an external timer to disable
the access device at certain times.
