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 cardholder that a second person must badge in or out
of the controlled area.
Hardware configuration
The control panel must contain the following rail modules:
• 3-SAC Security Access Control module
• 3-PPS/M Primary Power Supply module
