FJB2 Fused Junction Board
FJB2 Fused Junction Board
FJB2 Fused Junction Board it's an Intercall Nurse call. The FJB2 replaces the earlier FJB1 and provides four ‘spur’ outputs from the network spine with each output incorporating a over current/voltage and reverse polarity protection device. A front panel mounted red/green LED indicates the condition of the internal fuses and continuously monitors the network data signals. Individual fuse failure LED’s are mounted on the reverse of the unit and in the event of a cable fault, on one of the outputs, the ‘spur’ will be isolated without disabling the entire cable network.
