My comment was a joke.  I have dealt with engineers who think that regardless 
of the concept if the AHJ approves it then it's all good.  I have explained the 
responsibility to design that which is compliant with applicable codes and 
standards and the liability issue oft times to no avail.

If you think your liability went away when the "AHJ signed off" on an unlisted 
installation, think again.
Even if you had a P.E. write the letter and the AHJ accepted it you're the 
installer, and still Liable. Check with your insurance underwriter, they 
usually have some very fine lawyer's who can explain why your policy won't 
cover you for this.

You didn't really want to send your kid's to collage anyway did you?

Subject: Re[2]: Sidewall Sprinklers

Hello Craig,

I have an AHJ that suggested back to back sidewall heads under a low walkway to 
get the throw out to each side over the open space between the walkway and the 
front of the condo unit. The condos connect to the walkway via a "bridge" to 
the front door. There is dirt below the open space and could be
5 stories above to the roof/skylight. He also wants a sidewall head in the unit 
over the window that looks out to this area.
