Brian,
All of the programs have their selling features and each one is good for what it does. I guess it's the same reason there are still 4 or 5 major car manufacturers. Everyone isn't always a Ford guy or gal. The Bronze version of AutoSprink can do more than many of the other programs out there at about 1/2 the price if you consider that you have to piggy-back the other programs with AutoCad. Even if it was more,, I turn out about 75% more work than I did on one of the other programs. At twice the price (which it isn't even in the Gold version) it doesn't take long to get the return on investment.

I understand what you are saying but in practical fact; is it worth it? If we go antifreeze, we can stay within the residential boundaries, but going dry opens other issues. Can we get the manufacturers to test and list a dry sidewall head for these uses?

Those are sensitivity and distribution. The sidewall sprinklers must be tested to insure that they provide the appropriate sensitivity and distribution in distribution tests (RDD & ADD) as well as sensitivity tests and fire tests. I would not think that having a fire official just deciding one was better than the other is a really good idea. That smacks of the fire inspector saying he wants something done just because "he wants it that way".

Would there be a significant difference in the time it takes to fuse the two different types of heads?

Maybe some bleed over into exterior canopies. Mike Brown -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Brian Sent: Thursday, February 21, 2008 5:44 PM To: [email protected] Subject: Dry HSW under open framed 2x's I'm noticing a lot of small exterior canopies being protected with dry horizontal sidewall sprinklers even though it is open framing (usually 2X6's or 2X10's at 24" o/c) without any type of material fastened to the underside of this framing - which is all good and well since it mostly complies with NFPA #13 '07 ed section 8.4.2 except that it's not 'SMOOTH.' So I guess that's my question, they aren't smooth so how are people getting away with this? Smooth being defined as sructural members being spaced more than 7'-6" o/c. per A3.7.2. The only thing I can come up with is A8.15.7 where you can install a *pendant* at a 45 degree angle to protect small unheated areas so if it's okay for a pendant why not a HSW? (I'm sure it has to do with the intracacies of unfamiliar testing and listing requirements of a pendant over a hsw???) Any thoughts? Thx, -B- Below are the sections talked about: NFPA #13 2007 ED. 8.4.2 Sidewall Spray Sprinklers. Sidewall sprinklers shall only be installed as follows: (1) Light hazard occupancies with smooth, horizontal or sloped, flat ceilings (2) Ordinary hazard occupancies with smooth, flat ceilings where specifically listed for such use (3) To protect areas below overhead doors A.8.15.7 Small loading docks, covered platforms, ducts, or similar small unheated areas can be protected by dry-pendent sprinklers extending through the wall from wet sprinkler piping in an adjacent heated area. Where protecting covered platforms, loading docks, and similar areas, a dry pendent sprinkler should extend down at a 45 degree angle. The width of the area to be protected should not exceed 7½ ft (2.3 m). Sprinklers should be spaced not over 12 ft (3.7 m) apart. (See Figure A.8.15.7.) A.3.7.2 (3) Smooth Ceiling Construction. The term smooth ceiling construction as used in this standard includes the following: (a) Flat slab, pan-type reinforced concrete (b) Continuous smooth bays formed by wood, concrete, or steel beams spaced more than 7½ ft (2.3 m) on centers - beams supported by columns, girders, or trusses (c) Smooth roof or floor decks supported directly on girders or trusses spaced more than 7½ ft (2.3 m) on center (d) Smooth monolithic ceilings of at least ¾ in. (19 mm) of plaster on metal lath or a combination of materials of equivalent fire-resistive rating attached to the underside of wood joists, wood trusses, and bar joists (e) Open-web-type steel beams, regardless of spacing (f) Smooth shell-type roofs, such as folded plates, hyperbolic paraboloids, saddles, domes, and long barrel shells (g) Suspended ceilings of combustible or noncombustible construction (h) Smooth monolithic ceilings with fire resistance less than that specified under item (d) and attached to the underside of wood joists, wood trusses, and bar joists --------------------------------- Looking for last minute shopping deals?
