APPLICATION EXPANSIONS
Apart from standard-alone operation, DK-2882 is expandable to be a Multi-station System or a High
Security Multi-station Split-decoded System with its Data I/O Bus for the connection of the optional
auxiliary keypad(s) and decoder. The wiring is very simple. Just connect all the related devices in
parallel with the Data I/O Bus. The DK-2882 is the server that manages the data among them.
A Multi-station System provides higher security in access control and user convenience to operate an
electric lock at different locations. Such as a dual keypad system for area needs controlling of going
in and going out with user codes or EM cards.
A Split-decoded keypad system increases the overall security with keypad(s) installing outside and
decoder installing inside. It prevents the door can be opened due to sabotage at the external
keypad(s). A Split-decoded system is also compatible with the auxiliary keypads for multi-station
operation. It is a perfect system for overall higher security and user convenience.
The application examples here show the connections of the auxiliary keypads and the decoder to the
server keypad. Please contact your local agent for these optional devices if increasing security and
user convenience to the system is required.
The auxiliary reader / keypads and the decoders are compatible with all the 2nd generation keypads
in the DK-2800 series.
The version"A" auxiliary reader keypads are available, which provide Wiegand and RS-232 data
outputs.
