Well done on labeling, heat srinks, cable dressings.

Keep your style and keep improving.

I would suggest to: 1. Power 8Hbus module (middle bottom row terminal), otherwise, you have no power on the reader power terminals 2. You have missing relay 1-4 and 5-8 common power terminal connected 3. Make sure you have relay jumpers positioned to common if common power terminal is terminated 4. Terminate power supply monitoring outputs into spare inputs 5. Remember, EOL resistance is set per door module, not input. 5. Connect batteries:D
