Re: Victaulic LP4601

Not personally but I know we put a lot of them in. More generally, for the higher application (40' ceiling) the difference is not as big since the UL listing pressure is lower, it's still about 150 gpm more. With most of the designs we do today the hose stream is rarely a big issue because

RE: Victaulic LP4601

On that same note – we have come across some AHJ’s that are not at all comfortable with designs that are not covered by NFPA 13. Be sure to get the approach approved before you get too far along. Matt From: Sprinklerforum On Behalf Of Mike B Morey Sent: Thursday, November 08, 2018 7:17 AM

Class 1 commodity shrink-wrapped or encapsulated?

This is all based on the 2013 edition of NFPA 13. Section 5.6.3.1 gives you three criteria for how a noncombustible product is packaged. #3 says: Shrink-wrapped or paper-wrapped as a unit load with or without pallets. So my question is, does the shrink wrapping count as encapsulation, or can you

RE: Class 1 commodity shrink-wrapped or encapsulated?

Ben, I’m pretty sure that if it is completely encased with ‘shrink wrap’, that is a perfect picture of ‘encapsulation’. If the top of the pallet is left open but wrapped on the sides, then it would be non-encapsulated. Cliff Whitfield, SET President Fire Design, Inc. 184 Comfort

What Steve said. Generally, my experience has been that if they have a heat pump, max outlet temperature will be less than 100 degrees. But if they have a furnace, there is a good chance it will be higher. Mechanical designer/contractor should be able to answer the question. -Kyle M From:

Re: Sprinklers next to Diffusers

Why not use intermediate temp heads everywhere? Then diffuser proximity won't matter. Ron F On Thu, Nov 8, 2018, 1:57 PM Kyle.Montgomery wrote: > What Steve said. > > > > Generally, my experience has been that if they have a heat pump, max > outlet temperature will be less than 100 degrees.

Parts Mezzanine

We have a parts mezzanine that uses pick shelves with grated walkways between. It is about 130' x 186' with three levels. Aisles are 3'-4". The roof system is ESFR K17 sprinkler heads @ 52psi. I am using FM 8-9 but cannot seem to find what the design criteria for the mezzanine would be.

What is storage class? How wide are shelves for picking. Solid shelves? Are there possible obstructions on the walkways? How high is each level? Art Tiroly ATCO Fire Protection/Tiroly 24400 Highland Rd CLE 44143 216-621-8899 216-570-7030 cell From: Sprinklerforum

Deck and Balcony sprinklers

The IFC requires sprinkler protection for Deck and Balconies if the building is type V construction. Question: By Does type V-A construction fall into the TYPE V category thereby requiring the sprinklers? I don't see an exception for noncombustible deck materials, in this situation the deck

Re: Sprinklers next to Diffusers

Right. We had to very closely coordinate locations of sidewall sprinklers and sidewall registers in a luxury condo project several years ago where the soffit headwalls were angled and even wavy. We learned from the mechanical engineer for those particular dwellings that the maximum

RE: Deck and Balcony sprinklers

Your building is Type V construction. V-A and V-B just deal with ratings of the walls in certain areas. If you have Type V-A or V-B, you are putting sprinklers at the back areas. Travis Mack, SET MFP Design, LLC 3356 E Vallejo Ct Gilbert, AZ 85298 480-505-9271 fax: 866-430-6107

I agree Travis. I have a project where I included them and they are now trying to eliminate them. Just trying to get my ducks in a row. Thank you, Bob Knight, CET III Fire by Knight, LLC 208-318-3057 From: Sprinklerforum [mailto:sprinklerforum-boun...@lists.firesprinkler.org] On
