Final Keypad Installation  
After wiring the keypad (see next page), complete the installation  
by securing the keypad to the mounting plate.  
INSTALLATION  
Beforeinstallingthekeypad, theunitmustbepartiallydisassembled  
to access the mounting plate.  
If a lower beeper sound level is required, before installing  
the keypad, remove Jumper JP1 (place the jumper block on  
one pin to save the jumper).  
Opening the Keypad  
The keypad assembly is secured with two tamper-resistant screws.  
Refer to Figure 3 for disassembly details.  
Hook the keypad assembly onto the mounting plate tab (see  
Use the special allen wrench (supplied) to remove the two  
tamper-resistant screws.  
Separate the mounting plate from the keypad assembly.  
Figure 5).  
Use the special allen wrench (supplied) to install the two  
tamper-resistant screws.  
Fit the bottom tab on the faceplate into the slot on the  
keypad then snap the top of the faceplate in.

The yellow indicator will flash quickly while the AK-2W 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 entry code.The AK-2W 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 # Code # Code #  
Code = The entry code to delete.  
The yellow indicator will flash quickly while the AK-2W searches its  
memory for the code to erase. The green indicator will light when  
the code is erased.  
BASIC PROGRAMMING  
Erasing All Entry Codes  
When the AK-2W 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  
AK-2W 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.  
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  
Entering Programming Mode  
The 6-digit Master Programming Code (default = 123456) is used to enter  
Programming Mode.  
Press: 9 8 # Master Code # Master Code #  
Master Code = The new 6-digit Master Programming Code  
New master code: _____________________  
Press: # 9 # Master Code  
Master Code = the current 6-digit Master Programming Code  
PROGRAMMING OPTIONS  
Exiting Programming Mode  
There are several AK-2W programming options. For most  
installations, the factory set default options are sufficient. The  
keypad must be in Programming Mode to make these changes.  
Press: * * #  
The red indicator will light after exiting Programming Mode.  
NOTE: The AK-2W will automatically exit Programming Mode after two  
minutes of inactivity.  
PROGRAMMING AK-2W TO HOLD THE OUTPUT  
Linear’s AccessKey products have 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.  
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:  
The rules for a toggle output are:  
Press: * 9 #  
• If the output is OFF, it will turn ON and stay on until the next  
activation.  
Setting Entry Code Length  
Default: 4 digits  
• If the output is ON, it will turn OFF and stay off until the next  
activation.  
Press: 0 3 # Length #  
Length = 1 - 6 for entry code length  
Typical Programming  
With the unit in Program Mode, set the Auxiliary Relay (Relay #2)  
output to Toggle Mode using the following keystrokes:  
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.  
Press: 2 2 # 9 9 #  
22 = Programming Step; 99 = Toggle Mode

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.

Sets which output activates during the time access is granted. (Use this output  
to shunt alarm contacts attached to the access door.) This output may be timed  
or toggled.  
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.
