Millennium 
Systems
Each initial and supplemental cabinet in a Millennium system has a BIC 
that attaches to the cabinet’s terminal board (BLJ). The BIC provides 
controller access to alarm monitoring, battery voltages, battery currents, 
and temperature probes in the cabinet through the serial rectifier bus.
Vector Systems The initial cabinet contains the Vector controller, which consists of a 
BIC3 control board and a BLJ terminal connection board. Supplemental 
cabinets do not require a BIC.
