OPERATION AND FUNCTIONS OF THE SUPER USER PIN
1) Operate Output 1, 2, and 3
The operation of the Super User PIN is just like a normal User PIN. Simply key-in the PIN with a specific output
number for the desired Output.
---------- Output 1 Activates
---------- Output 2 Activates
---------- Output 3 Activates
2) Inhibit The User PINs For Output 1
The Super User PIN can also be used to inhibit the normal User PINs/Cards for the Output 1 (usually they are for
door strike). It enhances the security level of the access control system, such as to stop a keypad after office hour
or while the house is nobody inside. Once the Output 1 is inhibited, the User PINs/Cards for it become invalid and
those people even know the User PINs are refused during the system is inhibited. The inhibit function is toggled in
Start / Stop mode with the following code entry.
---------- The Whole Group of User PINs & Cards for Output 1 are Disabled
or Enabled in Toggle
NOTE:
The inhibit function setting with the Super User PIN applies to
ALL
the whole group of User PINs and Cards for
Output 1
ONLY
, but not for Output 2 and Output 3.
For safety reason, the inhibit function initiated with the Super User PIN does not govern the Egress Button. The
door still can be opened with it from inside.
RECORD THE COMMON USER PINS FOR OUTPUT 1, 2 & 3 (Locations 03, 04, & 05)
The Common User PINs 1, 2 and 3 are prepared for operating of the Output 1, Output 2 and Output 3 respectively as
an enhance code. The Common User PINs
MUST
work in the form of “Card + Common PIN” to operate the outputs to
increase the security of the access control system. See Locations 10, 20 & 30 for more information.
NOTE
: Common User PIN alone can
NOT
be used to operate the Outputs directly.

-- Location Stores The Common User PIN for Output 1
-- Location Stores The Common User PIN for Output 2
-- Location Stores The Common User PIN for Output 3
COMMON USER PINS
The Common User PIN can be 4 to 8 digits. Press # key to confirm the code entry.
When a new Common User PIN is keyed in and confirmed, the old one is replaced.
Example
: Set a Common User PIN with the number of “1 3 5 7” for Output 1 ----
To deleted a Common User PIN from memory: Key in just the Location number and #. ----

THE WIRE HARNESS FOR “WIEGAND DATA OUTPUT” & “APO DATA I/O”
NOTE:
The information in this section is
NOT
for the system in
Stand Alone
operation. It is not necessary to plug in the
wire harness to the socket, just leave it open.
The information below is for setting the DK-2882 keypad with the Wiegand data interface to a control panel, or the APO
Data I/O interface to an APO Controller to make up a high security split-decoded system.
Split-decoded Keypad System
Most of the general purpose keypads on the market are self-contained systems for stand alone operation. It controls the
appliance(s) directly with its output relay contact(s); such as the electric lock in an access control system. The electric
lock is connected to the keypad that is installed outside the house. The thief can open the door without a code or card
but just open the keypad box and make contact to the output relay terminal. It is a safety drawback in security.
The high security systems are usually operating in the Split-decoded mode that combines an outside unit for card
reading and code entry; and a control panel or a decoder unit installing in a secure closet inside the house. The outside
unit and the inside unit communicate in digital data with each other. All the commands are in digital codes, the thief can
do nothing to the inside unit even the outside unit is opened in sabotage. This design philosophy confirms high security
to the area protected, but not just relying on the protection of the keypad with the outer box and two screws.
The Wire Harness
The DK-2882 comes with two sets of interface wires from the wire harness. The Wires 1-4 are the Wiegand interface
wires. The Wire 6 is the Data Input/Output wire for the connection with the optional APO’s Digital Keypad Access
Controller, DA-2800 for high security Split-decoded operation. The Wire 5 is the Common Grounding point of these
signal wires.
The Wires :
1) Yellow --------- D1, Wiegand DATA 1
2) Green ---------- D0, Wiegand DATA 0
3) Brown --------- Buzzer control line, 0V active, for Wiegand audible status indication
4) Orange -------- Red LED control line, 0V active, for Wiegand visible status indication
5) Black ---------- (-) Common Ground
6) Pink ------------ APO’s data In/Out line, for APO’s decoder connection
