Maximum Number of Zones

Please first resolve the power connection issue. The hc595 should get 5v and GND from the Pi e.q. the top power rail.
The second power supply should only go to JD_VCC and adjacent GND.

Hi.

Removed the secondary power supply from the BOTTOM POWER RAIL.

Removed the GND wire from the TOP to BOTTOM POWER RAIL.

Removed the GND wire from the SHIFT REGISTER(s) to the BOTTOM POWER RAIL.

Removed the PURPLE wire from PIN 13 of SHIFT REGISTER to TOP RAIL GND.

Reconnected PURPLE wire from Pi to PIN 13 of SHIFT REGISTER.

DID NOT connect power to JD-VCC and GND of RELAY MODULES.

Turned the Pi on and waited for everything to boot up and get running.

Unplugged and plugged in the USB fan connected to the UPS surge protected outlet.

The optocoupler(s) did not trigger.  

Accessed SIP web interface and scheduled a RUN ONCE for one of the zones.  The associated optocoupler DID NOT trigger.  Tried several with no success.

Powered everything down and reattached the GND wires from the SHIFT REGISTER(s) to the BOTTOM POWER RAIL and the GND from the TOP to BOTTOM POWER RAIL.

Turned the Pi on and waited for everything to boot up and get running.

Accessed SIP web interface and scheduled a RUN ONCE for one of the zones.  The associated optocoupler TRIGGERED.  

Unfortunately when I unplugged and plugged in the USB fan connected to the UPS surge protected outlet the optocoupler(s) started to trigger.

Should I remove the GND(s) again and remove the PURPLE wire from PIN 11 of the Pi and reconnect PIN 13 of the SHIFT REGISTER to the TOP POWER RAIL GND?

Here is a picture of my current configuration.
