INTRODUCTION
The DK-2882 is a self-contained three relay outputs, vandal resistant and weatherproof keypad. It combines the
functions of digital keypad and proximity EM card reader in one unit.
The DK-2882 can work independently as a stand alone keypad or works together with an optional “APO access
controller” to form a high security split-decoded keypad system. It is also a card reader providing of 26 bits Wiegand
data output from reading of an EM Card and 34 bits data output from the entry of an PIN/code. The Wiegand data can
be used by consultants and end users when setting product design or system installation criteria.
The keypad comes with plenty of functions for owner’s selection via programming. Owners can take them freely to
tailor the desired features for their systems.
It is an ideal keypad mainly for Door Strike and Alarm Arm-disarm control. It is also a programmable industrial timer (with
the timing of 1 second to over 24 hours) for Automatic Operator systems.
The DK-2882 line of keypads have four versions. Versions A and B are designed for surface mounting on wall or fitting
on a standard gooseneck post. The C and D are the flush mount versions. They are designed to flush mount on solid
wall or hollow wooden wall with its back box.
DK-2882A – Output Relays for Output 1, 2 and 3 (Surface / Gooseneck Mount Version)
DK-2882B – Output Relays for Output 1, 2 and Door Bell (Surface / Gooseneck Mount Version)
DK-2882C – Output Relays for Output 1, 2 and 3 (Flush Mount Version)
DK-2882D – Output Relays for Output 1, 2 and Door Bell (Flush Mount Version)

The Duress Output switches to ( - ) ground when duress code is entered. You may use it to turn ON an LED
lamp and/ or a small buzzer to notify a guard; or connect it to a 24 hour Normally Open protection zone of an
alarm system.
Only one connection option is recommended. Make sure that the sink current does not exceed the maximum
rating of 100mA.
(E) DURESS OUTPUT
The Key Active Output switches to ( - ) ground for 10
seconds whenever a key is touched. You may use
it to turn ON an LED lamp and /or a small buzzer to

Make sure that the relay for switching ON lights
has high enough isolation between high voltage
and low voltage to prevent damage of the keypad.
Only one connection option is recommended. Make
sure the sink current does not exceed the maximum
rating of 100mA.
External power supply and isolation relay are strictly
