INTRODUCTION DK-2811 MK-II is a self-contained digital access control keypad that combines proximity EM card reader in one unit. 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. It also has a N.O. relay dry contact output for driving an external door bell. The keypad is employing the Tri-Tech design approach capable for 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.
