485
The DMP 485 Access Control Module Expansion card allows you
to add user code and event memory expansion as well as a variety
of access control capabilities. New or existing XR200 panels may
be upgraded to provide the enhanced operating capabilities of the
Model 485. Because the Model 485 uses both the existing XR200
memory and the new 485 memory, the upgrade instructions must
be followed exactly to assure a trouble free installation.
