I should have added it's a 13R in an apartment building. Yes we can theoretically upsize the combination main to account for both domestic and fire demands. However with the larger pipe the domestic flow does not adequately scour the pipe resulting in organic buildup. A prudent plumbing official will pick this up. With that said the best way is a separate fire main, 13D's being the exception.

The most failsafe solenoid is the one that's still on the shelf at the supply house. The essential basis of design in 13D is a system that is nothing more than an extension of the cold water system. No alarm is required if the house is fitted with SD's and there's only one way to turn everything off. Between ourselves and the AHJ community, things have strayed a bit from the KISS principle.
