Global Fire JUNO NET - Connection Schematic for Self-Contained Panels

In a self-contained panel of up to 12
loops, there is no requirement for an
RS485 Interface Board because the Sub-
Panels can be inter-connected via a TTL
bus.
The connections are made as follows:
CON1(J-NET-CON) to Cn4 (1st SUB-PANEL)
CN3 (1st SUB-PANEL) to CN4 (2nd SUB-PANEL)
Cn3 (2nd SUB-PANEL) to CN4 (3rd SUB-PANEL)
NOTE: There is no need to terminate
the last sub-panels’ CN3 because the
bus connection is a parallel one.
