e) SPLIT-DECODED ACCESS CONTROL DOOR LOCK
Description
Apart from stand-alone operation, the DK-2882 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-2882 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.
Make Operation Mode setting of the keypad in “Server Mode” with Location 94 = 1 in this application.
