Just to be clear this is a Listed product, not a whole lot of debate here.
Nowhere does it say UL Listing. The only requirement really where the AHJ comes
in is included in a list published by an organization that is acceptable to
the authority having jurisdiction. The only debate might be if
not sure exactly what your say so type slower and use smaller words - lol.
I was making the point that it has to be listed for fire protection and not
just a UL listing as an electric device. Were you disagreeing with that?

I would have thought that if the contractor is to provide an NFPA 13
compliant system, then I would think the listing of a product would have to
specifically state that it is listed for use in an NFPA 13 system (maybe it
does, I haven't seen the datasheet on the valve in question); without
getting
states that either the equipment, material, or service meets appropriate
designated standards or has been tested and found suitable for a specified
purpose.
I take that to mean it's questionable to use a 5 psi head in an NFPA 13 system.
However, the device suggested I think meets the part
Very possible and wasn't there a fire that started in the roof system of a
warehouse this year or last? Fire started in the roofing system and spread
uncontrolled since it was above the sprinklers.
I know of one here in SC where lighting hit the building and caused some
significant damage
Gentlemen,
I just toured a building with a standpipe and small booster pump in the
closet at the bottom of the service.
I have not seen this before and was hoping to get some general background
on this. Is it still installed today in some buildings, etc.
Thank you,
Joe
There was a large structure fire in Mesa Azizona at a new Apple facility last
month. 1,000,000sf plus facility. The fire originated under the rooftop solar
array and the fire caused a large area of the roof to collapse.

Not at all. I'll agree 100% on that. I was not checking my spelling and
there were a lot of finger slips (and the vodka may have had a slight
influence). It reminded me of your posts where the message is discernible
but you have a lot of misplaced tense and spelling errors like, not sure
exactly
1- I’m an engineer
2 - I’m a Southerner
3 - Have only had a sip of coffee (not that I don’t do the same thing in the
afternoon)
Nuff said

I agree Chris that the wording you referenced is as strong a language on
the matter the seems to be in NFPA 13.
It does however seem to lead to a 'grey' zone. While the suitability of the
device is question maybe black and white, the fact that NFPA 13 thereby
(Section 6.1) allows components that
Not uncommon when you have a 100 psi remote outlet requirement on the standpipe
and the water supply can't deliver that. Install the pump on the standpipe
system to compensate for the deficiency.

I would say quite possible.
More frequent causes include faulty electrical connections,
faulty/imperfect electrical equipment (fluorescent starters, thermostats
etc.) directly attached to it.

Don't agree if it's a Class I standpipe. There are two demands that should be
considered in a sprinklered building that is also furnished with standpipes -
the sprinkler demand and the standpipe demand. The next branch in the
decision tree is whether or not the standpipe system is automatic
Unless it is equipped with the old style sprinklers which spray 40% above the
sprinkler.

And I'll question the ability of most AHJs to make the call regarding
suitability. Maybe I'll trust Chris, or the Chris that's the FPE for the
City of Tacoma, but I know better about the guys in many local
jurisdictions. People who the Wizard has given gold badges to. Bet this

Roof didn't collapse. Roof decking was still in the air and solid, but warped
due to the heat and subsequent water from the fire department. It wicked along

I believe that there was a fire at a refrigerated meat warehouse in south
jersey. If I remember correctly, it started under the PV panels. The FD was
scared to put water on it. The site was a total loss.
Maybe a foam blanket would work to shut off the power, and control the
fire.
