Getting ready to really get into my DSC alarm system.... questions about all the power connections for any alarm system

[Holbs]

I will have 10-15 total devices that require power off my DSC 1832 alarm system. I know there is a mA rating for power supplies so will have to add things up to see if I have to go one larger.
Let's see... for sure 6 minimum PIR's (4 indoor, 2 outdoor), 2 glass break detectors, 2 control keypad panels, 1 Envsyalink card, 2 expansion cards.
That is 13 devices that need the DC power from my main DSC motherboard. I am at a loss at how to connect all power for 13 devices. Do folks use a couple wire nuts? Terminal strips? WAGO terminal blocks?
When try to google search about wiring power connections in alarm panels, 99% comes back as if just installing 1 device so that's no help.

I have a similar situation with my system here. Seven PIRs, glass break, sirens, remotes, two expansion boards and the Eyezon board. I power the remotes from and the expansion boards from the panel. Everything else is on a separate power supply with an additional two 8AH batteries. The panel has its' own 8AH battery. I forget what the output current of the supply is, but it's in the 5 amp range or higher. Testing it, everything works well, both with AC and with simulated power outages.

someone on the /homesecurity reddit just said the same thing about using a separate power supply for boards vs devices. May go that route.
Just bought a couple terminal connectors to try out. I really hate having messy wiring. And I love me some DIN rails!

I used good, old fashioned, terminal strips. One side is jumpered and the other side gets the devices. One strip for plus and another for negative.

Do a search for WAGO 221 Lever nuts.

I did order a 2nd power supply. Luckily, I also found out the need of another power source board ( DSC PC5204 PowerSeries Power Supply Module ) which supervises the power and also to the backup battery.

I do use WAGO connectors for electrical stuff. Should see the original mess of a 4 gang light switch without WAGO's
