• RAN (Risco Area Network) Bus for communicating with the PMC
GSM and PSTN are separate boards that can be plugged in to the Proxy board.
Communication between RSP and Proxy is either through any one of the above mentioned
interfaces and communication between the Proxy and the ACCB is over the LAN.
Multiple ACCB can be connected to one Proxy.
Access Control Controller Board
Access Control Controller Board (ACCB) board is developed as part of the RAC system project to
handle all Access Control logic. The ACCB handles all the access authorization decisions. It can work
independently without ACIS and ACUS and RSP Servers (as in, installation mode. See
5.4
Installation/Programming Mode for ACCB).
It controls the door elements such as the Readers, Sensors and Relays through the Access Control
Input Output (I/O) board (ACIB).
Features of ACCB
It has:
• Interface to two ACIB’s through RAN bus.
• Interface to LAN that connects it using a Proxy to the RSP Servers
• It can handle maximum of 4 doors
Access Control Input Output Board
The Access Control IO Board (ACIB) interfaces and controls the operation of door elements (Reader,
Sensor, Relay and others).
Features of ACIB
It has the following features:
• Interface to ACCB through RAN bus.
• Interface to readers
• Interface to monitor and control maximum of two doors, eight inputs (sensors) and eight
outputs (relays).
Readers
Reader is the device installed near the door to identify a Person. It can be a Radio Frequency
Identification (RFID) card read-only reader, RFID Read/Write card reader, Magnetic swipe reader, Key
pad reader, remote control reader or a biometric reader. It reads the card ID and data and transmits
to the ACIB.
Installer can configure Readers for each ACCB.
An ACCB is indirectly connected to:
• Maximum 8 Readers
