Update:
Order match the any flood, any fire, any alarm to the input links for flood,fire, any. They would work fine if you hooked them up right. This is just making the arrangement of the logic be inline with their respective on signals.

This boat has my most expansive damage control locations:

Ill see about improving the text description above.

Can you make a small example creation to show how it works? also can you add descriptions to all the nodes in the logic view?

Added another pic showing 7 water, 6 fire and other alarms. This shows the linking system works. The cold warning is independent and doesn't go through the DamCon MC so doesn't set off the master alarm. Pumps in the sample ship activate based on when their attached compartments have flooding vs on smaller ships where one pump handles the whole ship.
One of the benefits of the controller is it is also a logic check that things have been wired up and responses set, by compartment and overall.

Fixed missing or logic on final logic for master alarm

Programming change on the extra threshold test. It will now allow within that threshold. I think that's easier to remember on new installs.
So for say low fuel is you have a capacity if 20,000 L set the threshold to trigger on 2,000 (10%) to -100,000 (minus alot). Feed into the number input the sum of your fuel tanks like from the adding MC's Ive posted
