Apart from standard-alone operation, AR-2808 is expandable to be a Multi-station System with the
optional auxiliary reader AR-2802. Maximum three optional readers can be allowed and the
connection is very simple. Just connect the devices in parallel with the Data I/O Bus of the
AR-2808. The AR-2808 acts as a server of the system and 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 reader system for area needs controlling of
going in and going out with proximity EM cards.
The optional reader is available in standard version (AR-2802S) and advanced version
