INTRODUCTION
The AC-228 keypad is a digital keyless entry system designed for
access control applications. The keypad is housed in a rugged, plastic
enclosure and is designed to be mounted in a standard single-gang
electrical box. The die-cast keys have bright, easy-to-read yellow
graphics.
Up to 480 entry codes, from 1 to 6 digits in length, can be programmed.
They can activate either, or both of the relay outputs. The “anti-
passback” feature prevents using the same code again before the
programmed time elapses.
All system indicators are long-lasting, solid state LEDs. Two indicators
show the status of the entry system. The left indicator lights red to
indicate power, then turns green when access is granted. The right
indicator lights yellow when the keypad is in “lockout” condition (from
too many incorrect code entries). An internal sounder beeps when each
key is pressed. An internal jumper sets the sounder volume high or low
The SENSE input can be used two ways. If programmed for “door
sense” the input is wired to a normally closed switch on the door to
detect when the door is opened or closed. Forced entry or door ajar
situations can then be detected. Using door sense, the “Auto-relock”
feature will prevent “tailgating” by turning off the Main Relay output
immediately when the door is closed after access has been granted. If
the SENSE input is programmed for “inhibit”, the input can be wired to a
“service” switch or automatic timer that will disable the Main Relay when
required.
The REQUEST-TO-EXIT input can be wired to a pushbutton to provide
codeless activation of Main Relay, Auxiliary Relay, Output #3 or Output
#4 (programmable).
The ALARM SHUNT output activates when access is granted. This
output can be wired to shunt alarm contacts on the access door/gate to
prevent triggering of an alarm when authorized access occurs.
The AC-228 keypad is powered from a 12-24V 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. An internal jumper is provided to
reset the master code. The Main Relay has a 5 Amp capacity. The
Auxiliary Relay has a 1 Amp capacity. 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-exit, and
keypad active conditions.

KEYPAD WIRING
See Fig. 6 for an example of a basic door installation. The keypad is
mounted adjacent to the door. An electric door strike is mounted in the
door jamb to release the door lock. A magnetic switch is mounted on top
of the door jamb for detecting when the door is open.
Use the following steps to wire the keypad. Refer to the wiring diagram
shown in Fig. 8 to assist in the wiring.
Note: Up to 500 feet of 18 AWG wire can be run for power, use larger wire
for longer runs. Use 22 AWG or larger (depending on load) for other
connections.
Output
Install a low voltage electric door strike for unlocking the door.
Route two wires between the door strike and the keypad box.
Connect one of the door strike wires to the keypad’s MAIN RELAY
N.O. terminal (TB1 #3). Connect the other door strike wire to the
keypad’s AC/DC+ terminal (TB #1). Connect a wire between the
keypad’s AC/DC- terminal (TB #2) and the MAIN RELAY COM
terminal (TB #4).
Power
Choose a location for the power supply or transformer.
Route two wires between the door strike and the keypad box.
Connect the power supply’s output terminals to the keypad’s AC/DC
input terminals (TB #1 & #2). Observe wiring polarity if using DC.
Caution: If the unit is AC powered, make sure the secondary
of the system transformer is isolated from earth ground.
Earth Ground
To avoid damage to the unit from static discharges, connect the
EARTH GROUND black wires E1, 4, 5 or 8 to a good earth grounding
point. Suggested wiring size is 18 AWG for earth ground.
Sense Input
RE Note: SENSE terminal (gray wire) can be programmed for either a
door sense or inhibit input. Both features cannot be used at the same
time.
To use the door sense feature to detect forced entry or door ajar
conditions, install a normally closed door switch on the door and route
two wires from the switch to the keypad box. Connect the door switch
to the keypad’s SENSE terminal (gray wire E8) and COM terminal
(any black wire).
If an inhibit switch or timer is going to be used for temporarily
disabling the keypad, route two wires from the switch or timer to the
keypad box. Connect the inhibit switch/timer normally open terminals
to the keypad’s SENSE (gray wire E8) and COM (black wires)
terminal.
Request-to-Exit Input (wiring shown on page 2, fig. 2)
If a request-to-exit pushbutton is going to be used, route two wires
from the keypad box to a normally open pushbutton mounted on the
secure side of the door. Connect the wires to the pushbutton and to
the keypad’s EXIT (violet wire E6) and COM (black wires) terminals.
Solid State Outputs
The two solid state outputs (Outputs #3 & #4) can be programmed to
activate during various conditions. These outputs can be used to activate
indicators or sounders. See fig. 9 for wiring examples using the solid state
outputs.

BASIC PROGRAMMING
When the AC-228 is in Programming Mode, both indicators will
turn off until programming begins. After a programming option
number is entered, the yellow indicator will blink. This shows that
the AC-228 is ready to accept the new programming data. After
the new data entry is complete, the yellow indicator will flash while
the data is being stored. The green indicator will light if the data is
accepted. The red indicator will light if any programming data is
entered incorrectly, and the command will have to be fully re-
entered.
Entering Programming Mode
The 6-digit Master Programming Code (default = 123456) is used
to enter Programming Mode.
Press: # 9 # Master Code
Master Code = the current 6-digit Master Programming Code
Exiting Programming Mode
Press: * * #
The red indicator will light after exiting Programming Mode
Note: The AC-228 will automatically exit Programming Mode after
two minutes of inactivity
Re-entering a Command After a Mistake
If the red indicator lights, signaling an incorrect entry, or an
incorrect key is pressed during programming, to clear the keypad
and re-enter the command:
Press: * 9 #
Re-entering a Command After a Mistake
If the red indicator lights, signaling an incorrect entry, or an
incorrect 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 # Length #
Length = 1-6 for entry code length
Note: If the Entry Code Length is going to be changed from the factory
default of 4 digits, make this change first before programming any entry
codes.
Adding a New Entry Code
Press: 0 1 # Code # Code # Relay #
Code=The new entry code: 1-999999, depending on code length
Relay=Relay output entry code will activate:
1=Main Relay 2=Auxiliary Relay 3=Both Relays
The yellow indicator will flash quickly while the AK-3 searches its
memory for available space and duplicate entries. The green
indicator will light when the new code is stored.
If the new entry code chosen is already being used for another
entry code, the red indicator 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 code. The AC-228 will
internally add any zeros to fill 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 # Code # Code #
Code=The entry code to delete
The yellow indicator will flash quickly while the AC-228 searches
its memory for the code to erase. The green indicator 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 indicator will light while the memory is being erased. This
may take up to 15 seconds.
Changing the 6-Digit Master Programming Code
Press: 9 8 # Master Code # Master Code #
Master Code=The new 6-digit Master Programming Code
New master code: ____________
PROGRAMMING OPTIONS
There are several AC-228 programming options. For most
installations, the factory set default options are sufficient. The
keypad must be in Programming Mode to make these changes.
Programming the AC-228 To Hold the Output
The AC-228 has a programmable “Toggle Mode” available for
each relay and solid-state output. When an output is programmed
for Toggle Mode, the output alternates from OFF to ON or from
ON to OFF each time it is activated.
The rules for a toggle output are:
If the output is OFF, it will turn ON and stay on until the next
activation.
If the output is ON, it will turn OFF and stay off until the next
activation.
Typical Programming
With the unit in Program Mode, set the Auxiliary Relay (Relay #2)
output to Toggle Mode using the following keystrokes.
Press: 2 2 # 9 9 #
( 22=Programming Step; 99=Toggle Mode )
Page 5 08279830 Rev.01/07 Page 5 of 8

Select Door Sense or Inhibit Input Default: Door Sense
The input (gray wire) can be programmed for DOOR SENSE or
INHIBIT. Press: 1 0 # Input #
Input=0 for Door Sense; =1 for Inhibit
When programmed for DOOR SENSE, 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, a closed condition 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.
Select Forced Entry Output Default: Output #3
Sets which output activates if the DOOR SENSE input opens
before access is granted. This output is not timed.
Press: 1 1 # Output #
Output=Output to Activate(0-4)
1=Main Relay; 2=Auxiliary Relay; 3=Output #3; 4=Output #4;
0=No Output
Select Door Ajar Output Default: Output #4

open 60 seconds after access is granted. This output is not
timed. Press: 1 2 # Output #
Output=Output to Activate (0-4)
1=Main Relay; 2=Auxiliary Relay; 3=Output #3; 4=Output #4;
0=No Output
Setting Entry Code Length Default: 4 digits
Press: 0 3 # Length #
Length = 1-6 for entry code length
Note: If the Entry Code Length is going to be changed from the
factory default of 4 digits, make this change first before
programming any entry codes.
Select Keypad Active Output Default: No Output
Sets which output activates when any keys are pressed. This
output is timed. If toggle mode is selected for the output, the timer
value defaults to 2 seconds.
Press: 1 4 # Output #
Output=Output to Activate(0-4)
1=Main Relay; 2=Auxiliary Relay; 3=Output #3; 4=Output #4;
0=No Output
(Typical Programming cont.)
Program all normal entry codes to use the Main Relay (Relay
#1), and only Relay #1 as the output relay. Program the code(s)
that you want to use to hold the output for an indefinite period to
the Auxiliary Relay (Relay #2). See the following example that
sets entry codes 1234 for normal and 5678 for toggle operation.
Press: 0 1 # 1 2 3 4 # 1 2 3 4 # 1 #
01=Programming Step; 1234=Entry Code; 1=Main Relay
Press: 0 1 # 5 6 7 8 # 5 6 7 8 # 2 #
01=Programming Step; 5678=Entry Code; 2=Auxiliary Relay
Typical Toggle Mode Wiring
For devices triggered by a normally open circuit, wire the
contacts of the Main and Auxiliary Relays in parallel (see the
Figure below). Either relay will be able to trigger the access
device. Entry codes programmed for the Auxiliary Relay will be
able to hold the output on.
