BLJ Terminal Board
Millennium
Systems
A BLJ terminal board is located inside the door of each initial and
supplemental cabinet of a Millennium system. The BLJ is the
termination point for distribution alarms in each cabinet. It uses the
rectifier serial bus to communicate with the controller.
Vector Systems
The Vector controller, which is installed in the initial cabinet, contains
a BLJ terminal connection board. This board is daisy-chained to a BLJ
board in each supplemental cabinet.
Bay Interface Card
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.
