INTRODUCTION
The DK-2882 line of keypads 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 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 DK-2882 comes with plenty of functions for owner’s selection via programming. Owners can take them freely to
tailor the desired features for their system.
DK-2882 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 has four versions. Version 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.
