I wouldn't expect it to be dry (or chemical, which is what you're referring to) because of the first cost and a wet system would function just fine. I could be wrong.
I am familiar with sprinkler systems in ~100 buildings that I oversee and do design work for, as a frame of reference. Very few are dry systems - mostly parking ramps and a few very highly sensitive areas. Some are chemical systems - such as helicopter landing pads and datacenters.
Mainly attics. Anywhere that can freeze. I hate installing dry systems. They are a nightmare compared to wet.

I guess in all this, we're assuming it was a sprinkler pipe. I don't know if that's actually been confirmed yet! I still wouldn't expect the piping at the top of Hilton to be dry because there's no attic there (to my knowledge) - it's open to structure with that wood grid which is open.

I would think it would be wet also. Agreed that we don't know its a sprinkler pipe.

Would sprinklers be effective up there for fire suppression?



Plenty of buildings have their HVAC stuff on the roof. Handy place to put things where nobody can see them.



... Or if the chillers were on the roof... As it appears they are on Google Earth...

Absolutely, the roof is a convenient place. However these HVAC units are not on the roof, when you look up and see all the boards in hilton, thats a suspended ceiling most all of the mechanical equipment like HVAC is there- not on the roof.

I have worked in the ceiling of Hilton in the dead of winter and have never been cold. I would be very surprised if there was a dry sprinkler system in the ceiling.
It's even hot if you're sitting in the top row or two of seats.

What's the difference between a "dry" sprinkler system and a chemical sprinkler system?

I'm totally ignorant, so use small words, please!

Dry = filled with air until a head pops, at which time the "dry valve" opens and fills the previously dry system with water to suppress the fire. Typically used where wet systems would freeze like canopies, overhangs, attics, walk-in freezers and coolers, etc.

Chemical = chemical in lieu of water, typically used to not damage the area served as much as being covered in water would. Used frequently in data centers, high value libraries, sometimes museums, things like that.

Dry systems usually used in freezers and such: the pipes are filled with compressed air until activated then water pumps through.
