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.
