3.1 Functional description and components
3.1.1 Function
The Access Control serves to monitor rack doors via
an infrared access sensor. In addition to this, a CMC
III reader unit and a handle can be connected to the
interfaces. The access sensor reports to the CMC III
Processing Unit (base systems) whether the door is
open or closed. Codes for the door release are input
on the coded lock. The door can then be opened and
monitored with an electromagnetic handle. The Access
Control has an identification that allows it to be detect-
ed automatically by the CMC III Processing Unit (base
systems).
Note:
In the following text, the designation
"CMC III Processing Unit" refers to the
"CMC III Processing Unit" variants and also
