CONNECTION TERMINALS
1 - 2 : 12 - 24V DC (Power Input Terminal)
Connect to 12-24V DC power supply. The (-) supply and (-) GND (terminals 2 & 12) are the common
grounding points of the keypad system. No selection jumper is required for the full input voltage
range. Connect DC power with the (+) and (-) polarity indicated.
3 - 4 : OUTPUT 1 (Output Relay 1)
Output 1 is a relay controlled by the group 1 user codes/cards. Its output
contact has maximum rating of 2 amp and is selectable for Normally
Closed (N.C.) or Normally Open (N.O.) with jumper. It is mainly for electric
door lock actuation. Use N.O. contact for Fail-secure electric lock while
N.C. contact for Fail-safe.
The output contact is programmable for Start / Stop (toggle) mode or timer mode.
See programming Location 51 for the details.
5 -6 : OUTPUT 2 (Output Relay 2)
a) Standard Version (DK-2836A)
This is an auxiliary relay output with 2 Amp rating Normally Open
(N.O.) or Normally Closed (N.C.) dry contacts controlled by the group
2 user codes, which is ideal for controlling security systems &
automatic operators. It is programmable for Start / Stop (toggle)
mode or timer mode.
See programming Location 52 for the details.
b) Bell Button Version (DK-2836B)
Output 2 is controlled by the “BELL” button on the keypad. It operates as long as the bell button
is pressed. Use N.O. contact to trigger an optional door chime.

3) Split-decoded Access Control Door Lock
Description
Apart from stand-alone operation, the DK-2836 can be up-graded to high security Split-decoded
operation with a decoder unit DA-2800 or DA-2801. The decoder is inside the house with all the
input and output installations connecting to it. The DK-2836 manages the data in the system
with its Data I/O Bus. The decoder operates the door lock and the appliances directly according
to the commands from the keypad unit. This approach prevents the electric door lock or
appliance be operated due to sabotage at the external keypad.

this application.
NOTE:
Connect the 1N4004 as close as possible to the lock in
parallel with the lock power terminals of the lock to absorb
the back EMF to prevent it from damaging the keypad. The
1N4004 is not required if the electric lock is AC operated.
To avoid Electro-Static-Discharge from interfering with the
operation of the keypad, always ground the (-) terminal of
the keypad to earth.
Always connect DOOR SENSOR terminal to (-) ground if not
used.
Always connect TAMPER terminal to (-) ground if not used.
Make 3-wire Connection (+, -, DATA I/O) to the keypad in
the DK-2800 series. More than one keypads can be
connected in parallel.
