INTRODUCTION

DK-2822 MK-II is a self-contained full feature digital access control keypad that combines proximity
EM card reader in one unit. It can be flush mount on a single gang box or surface mount on its plastic
mounting box.
The keypad has two outputs. The output 1 is a solid state relay selectable to drive Fail-safe or
Fail-secure electric lock. Solid state relay gives longer service life and prevents sabotage of energizing
the output relay to open the door with a strong magnet. The output 2 is a standard relay with N.C.
and N.O. dry contacts for auxiliary controls or as a door bell button contact.
The keypad is employing the Tri-Tech design approach capable of system expansion. It works
perfectly in stand alone operation, split-decoded operation for security enhancement with the
optional decoder, and multi-station operation for user convenience with the auxiliary keypad-readers.
The keypad is ideal for access control and alarm system arm-disarm control. It is also a
programmable industrial timer (from 1 second to over 24 hours) for automatic operator system.
