2010 edition. This rule is for actiavation so it is the position of the bulb that matters, not the deflector orientation, just my two cents. Brad On Jul 18, 2016 2:35 PM, "Parsley Consulting" wrote: > Taylor, > perhaps expanding on Ryan's comment, it doesn't

Re: Changes in Ceiling Elevation

Taylor, perhaps expanding on Ryan's comment, it doesn't appear to me that it would be applicable as the EC HSW above is not governed by anything in section 8.8, rather it's covered in 8.9, and there's nothing in 8.9 or its annex which matches the diagrams you referred to in 8.8. Count

I understand that, but, the head making up the distance to the high head is still a pendent. Just curious why this couldn't apply to the type of arrangement I'm proposing. TAYLOR SCHUMACHER, CET Security Fire Sprinkler P 320.656.0847 | F 320.656.0312 | E tay...@sfsprinkler.com From:

I would say no. 8.8 is rules for "Extended Coverage Upright and Pendent Spray Sprinklers". Ryan Labrie Fire Protection Designer Critical System Solutions, LLC 2830 Scherer Drive, Suite 300 St. Petersburg, FL 33716 Office: 727.209.5122 Fax: 727.209.5126 Cell: 813.394.3978 Email:

Changes in Ceiling Elevation

Can the rules of NFPA 13, 2013 ed., 8.8.4.1.1.4(B)-see also Figure A.8.8.4.1.1.4(A) be applied where the low sprinkler is a pendant in a soffit and the high sprinkler is a sidewall? It reads "Where the distance between the upper ceiling and the sprinkler deflector is less than or equal to 36

Re: Auxiliary dry valve drains

The drain test is needed if it is downstream of a valve. Every valve needs exercised, and a flow test needs conducted after the closed valve is restored to the open position. On Jul 18, 2016 1:05 PM, "rongreenman ." wrote: > John has stated and defended. Mike has stated.

Re: Auxiliary dry valve drains

13 only requires an initial acceptance test to establish baselines for the subsequent maintenance checks per NFPA 25. What a local yokel requires is only relevant to that locality and shouldn't be presented on the Forum as unequivocal without propose references. It's also important to know what a

RE: Auxiliary dry valve drains

NFPA 25 (2014) section 13.2.5 states “A main drain test shall be conducted annual for each water supply lead-in to a building water based fire protection system to determine whether there has been a change in the condition of the water supply.” 13.2.5.1 “Where the lead-in to a building

Re: Auxiliary dry valve drains

All the AHJ's in my area require a main drain test for all systems even if you have a header with multiple riser checks and dry pipe valves on it. NFPA -13 does not state that only one main drain test is acceptable, it plural not singular in the text. Mike

Re: Auxiliary dry valve drains

John has stated and defended. Mike has stated. Mike, defend your position. I'll side with John, using his defense and add that that only one main drain test is needed for any lead-in, no matter how many systems and auxiliary systems it supplies if all originate from the same header. And, as an

RE: Auxiliary dry valve drains

Todd: The 2" main drain test is primarily intended to verify that the water supply to the sprinkler system is not impaired, not to make sure the drain flows freely. 8.16.2.5 (2013) Has no requirement for a full flow drain test. It only details the size requirements relating to the capacity of

Are full flow 2" drain tests required for auxiliary dry valves? Todd G Williams, PE Fire Protection Design/Consulting Stonington, CT 860-535-2080 (ofc) 860-608-4559 (cell) Sent using CloudMagic [https://cloudmagic.com/k/d/mailapp?ct=ti=6.0.64=8.2]___
