Access control applications
EST3 Installation and Service Manual 3.31
Card reader
This application works best with card readers that support dual
LED control. The CRC uses the second LED (or LED state) to
signal the visitor that the escort must badge in before access is
granted.
Hardware configuration
The proximity card reader and barcode card reader are connected
to the same terminals of the CRC.
SDU programming
When an escorted visitor tries to enter a controlled area without
an employee, the CRC generates an access denied escort event.
You can select a predefined command list that the CPU executes
in response to this event.
ACDB operation
Like employees, visitors must be assigned an access level using
the ACDB. The site security officer can elect to assign the same
access level to all visitor cards, or assign different access levels
to ranges of visitor cards.
