How many cards or number codes can be stored in the system?
By filling the file “access.cmc3” directly to configure the access rights, the number of
programmed codes and the number of cards that can be taught on the system are unlimited.
The configuration dialogue on the website is limited to 1000 cards.
Can a number code or a transponder card be used to open an external lock, e.g. a
door buzzer, or activate a magnet?
Yes, not only a door buzzer but also a magnet can be controlled with a combination lock or a
transponder reader. This requires, however, the use of a 7030.040 I/O Unit or a 7030.050
Power Unit whose outputs can be switched (I/O Unit = four relays, Power Unit = two C13
outputs).
In this case, a virtual device with the designation
“
Access Controller" must be created in the
configuration of the CMC III and assigned the associated output, relay or C13 output. This
Access Controller can then be selected in the general access configuration in which codes
and cards can be assigned to a handle and will be treated by the system as a handle.
What card standard does the 7030.230 CMC III Transponder Reader support?
Our 7030.230 CMC III Transponder Reader supports the "Mifare" standard. A detailed
description of the supported tags is contained in the technical details of the transponder
reader on the website
Can other card types also be integrated?
The CMC III provides the capability to integrate third-party reader units. There are two types
of connection: using a digital input or using the 7030.190 Universal Sensor and its Wiegand
interface.
A digital input can be connected, provided the third-party reader system has a relay output.
In this case, the user administration must be made on the third-party reader system because
the CMC III cannot differentiate which user opened the door.
If, however, the connection is made using the Wiegand interface, the associated code will
also be transferred to the CMC III. This code can be assigned to a user and the logging lists
when the user opened the door.
Is it possible to release one or more doors if two cards or two numerical codes are
used (4-eyes principle)?
From software version V3.15.00, the 4-eyes principle may be configured directly in the
CMC III software. The cards/codes may be divided into one of two authorisation levels. One
card with a higher authorisation level is always needed to release the door.
Can the software be set in such a way that users need a card and a numerical code?
The software does not directly support a 4-eyes principle with card and code, because with
this system both entries (code/card) must be made on the same reader unit. The only way of
implementing a 4-eyes principle with a card and a code is by means of an additional CMC III
I/O unit. In the software, you link the cards to one relay of the I/O unit and the codes to one
relay of the I/O unit using a virtual device. Using a task, you may then program the handle to
open when both relays are switched.
