Intercall 600 - FJB2 Fused Junction Board

Intercall 600/700 Installation & Operation Guide Issue 4.27 Page 43 of 78
FJB2 Fused Junction Board.
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. Idividual 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. Please refer to page 20 for more information on the use of this unit.
Input / Output Terminals: Connect to the network spine and can be daisy chaned as shown above.
Note: The two Input/Output terminals are not protected or monitored.
Output(s)1,2,3,4: Individually fused and monitored network outputs.
Fuses: 4 off 315mA (0.315Amp) Anti-Surge 20mm Fuses.
Status LED indications: Flashing Green – Network healthy & All fuses ok.
Flashing Red – Immediate Network data error.
Flashing Red/Green – Recent Network Data Error. (In last 10 minutes)
Continuous Red – Fuse Failure. (Remove unit to investigate further)
Installation: Flush mount into ‘double gang’ electrical back-box. Surface mount using BB1.
Size & Weights: 160 x 115 x 20 mm, 70g
