Closest is Tyco SW-24 for up to 16'x24' discharge BUT only listed for OH-2. Other than that, there are no other options if in fact the area requires a .30 criteria. It really depends on what criteria they used to determine the .30 as being suitable for the storage commodity located within this area. So sorry but SW's are not an option on the plate for this application. They should have done some research before specifying a flying, purple unicorn. Craig L.

They haven't said what the storage criteria is but said to protect it at .3/2500. Bobby Gillett Sr. Project Manager Key Fire Protection, Inc.

Guess they won't back up on their concept of SW's huh? Whether the head will transmit enough cold to cause a freezing condition inside depends on the climate. But I wouldn't put any money on it unless you were in S. Texas, Arizona, Fla or So. Cal. Just curious but what density did they call out for the storage area? Did they list what materials were being stored or just pick a "it felt good" Hazard category from NFPA 13? Craig L.

So now I need to find an EC SW listed for storage that will throw 16' under one canopy and 22'-0 under the other. Of course I cannot find one; any know of any I might be overlooking?

What's the problem? Seriously, if it's storage they should have considered a dry system based on the depth of the area. The walkway, not enough info. If it's just a convenience walkway and not part of a required egress path, constructed of non-combustible components, not designed to accommodate any storage and separated from the occupied part of a building by a non-combustible separation it PROBABLY won't require to be sprinklered but more info would have to be shared to render a more substantial yeah or nay.

Project we r bidding is asking for Dry sidewalls for exterior storage canopies - one is 22'-0 deep and the other is 16'-0. The best I could find was an EC Dry SW for OH that throws up to 20'-0. I believe they need a dry system for each one. While I am at it they have a "covered walkway" (as its labeled) 11'-6 deep attached to building - not requesting sprinklers but I feel they will have to it. What say ye?
