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.

The keypad is designed to fit into a single-gang electrical box. The
box must be deep enough to accomodate the protective plastic
enclosure. Select a location near the controlled door and choose
a convenient height for the keypad. Be sure there is good wiring
accessibility for the unit’s power and the output to the door strike
or access device.

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 AK-21W 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

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
