The Water supply valve at the entrance should be supervised to a minimum of a zip tie or breakaway lock. This service entrance is a perfect way for someone purposefully setting fire to the structure to impair it without restriction. The alarm flow control would also be impaired.

Unchainable and unmonitorable fire protection valve on the outside of the building. Real smart, Arizona haha. Also, it would be nice to see a hose connection before the PRV.

Thanks for the information. I will be moving into a house with fire sprinklers soon and this will help.

Must be a warm weather zone .

We’re. Should they be

I personally don’t care much for residential fire protection systems that are separate from domestic water system. Reason being 90 % of home owners are ignorant of utility systems (HVAC,SANITARY,SEPTIC,WELLwater,MUNICIPALwater,ELECTRICAL) ask any trades person,in their home until they fail in some manor. By integrating fire protection into domestic in a series problems will show prominently and will be constantly “flushed” . I know this means eliminating dead end branches ,more careful planning . Doing this virtually eliminates “forgotten “maintenance. I have seen little attention paid to designs using this design premise.
