3) Split-decoded Access Control Door Lock
Description
Apart from stand-alone operation, the DK-2890 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-2890 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.

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
