Sounds like it is required Without seeing a floor plan hard to call

Without seeing a floor plan. A little hard to call A few reasons maybe 1. Door is part of a rated assembly 2. Door is part of enclosed rated stair 3. Stop the spread of fire from one floor to another 4. Other reasons Does the door swing in direction of travel to an exit?

Aikah Have you looked at using extended coverage pendants ?

It is something Without seeing it on site. A little hard to make a call Can you place sprinklers around the perimeter, far enough away, to spray under???

Good Ouch even the underground So the EX son in law did not look at the right YouTube videos.

I do not understand why the local ahj is not notified Let them look at it and deal with it.

Do you know how old the install is? Do you turn this in to the ahj or whoever regulates sprinklers? A red tag goes directly to the ahj within 24 hours in the state I am in. I wonder if some ahj approved it?????

Do you know how long it has been there??? I wonder who did the underground??? Have the osy ever been turned on ? Is it in the shop area also? Can you post a few pictures You sure his brother in laws fire sprinkler company did not do the work??

NFPA 13 Sorry do not have the book, readily available So 1. Install per manufacture instructions 2. Install per listing, the cvpc you need the specific brand, but most if you get the entire install instructions,,, up front the listing says pipe cannot be installed bare,, must have...

Yes for several reasons 1. To help the sprinkler activate 2. So the fire and smoke does not extend into the unprotected area, at the top 3. The cvpc normally has to be protected, normally by drywall So yes add the ceiling I am guessing it does not have to be fire rated. So fit it in as best...

Here is one . AGF recommends installing Model 7900AAV near the high point of the system, at the end of branch lines, and on top of supply risers. https://agfmfg.com/purgenvent/air-venting-valves/7900aav/ Read the instructions for the one you might use

Did not think it mattered What does the manufacture install instructions say

Ok so sounds like maxing out each riser.

What is the sq ft/ size of the building?? How many risers will there be?
