Zone Connections (J1)
Figure 3 shows how to make the zone positive, zone negative and screen connections between the SRP
panel and the SRM(s).
Figure 3 – Zone Connections
Please note that the “SCREEN” terminals on the SRM should only be connected to the zone cable screen
and NOT to the building earth or the back box earth terminal. The cable screen is connected to earth at
the panel end only, via the zone “SCRN” terminal. It is important to maintain the screen continuity in
order to protect against data corruption from interference.
Fault Monitoring – Zone connections are power limited and supervised. Open and Short faults cause a
loss of communication between the SRP panel and the SRMs. They are detected and annunciated by the
SRP panel.
