    I got a real problem with a self storage facility

    UFT12, I don’t believe we are talking about protecting racks as SD2 stated “… I wish it had racks..” in his original post. Therefore I would think we are discussing it being considered piled storage. In my previous post where I was referencing the possibility of utilizing Misc Storage criteria...

    I got a real problem with a self storage facility

    I have the 2013 Handbook at hand so that’s what I’m referencing for section numbers, etc. It would seem that you are getting to your EH2 hazard classification by going to Chapter 15: Protection for Palletized, Solid-Piled, Bin Box, Shelf or Back to Back Shelf storage of Plastic and Rubber...

    autosprink program

    Actually I believe it's the other icon (lock) that you'll have to click to unlock.

    I believe you have 'locked' your clipping slider. Find the toolbar shown below and click on the 4 arrows.

    30" Round Spiral Ducts Under ESFR Heads

    It is my understanding that baffles are not required. Logic being that with such close spacing if more than one sprinkler is being effected, that it is also going to basically be in the plume of the fire, and that it will therefore'overcome' the cold soldering effect. If it doesn't overcome the...

    30" Round Spiral Ducts Under ESFR Heads

    Have seen those 'pie pans' too Travis :). In fact you'll see them in Dublin (Ireland) airport - which is pretty embarrassing. cdafd, no I wouldn't be calling those heat collectors. I'd consider those to be water shields. I was referring to the section in FM 2-0 that UFT12 referenced. FM 2-0...

    NFPA 20 - impact on horsepower reduction as it relates to pressure and flow

    Dear Forum. NFPA 20 2013 Section 11.2.2.3 thru 11.2.2.5 discusses and has equations for modifying engine horsepower for installations with temperatures and elevation. However, is there a way to know/calculate what impact that reduction of horsepower will have on pump flow/pressure? Any insight...

    30" Round Spiral Ducts Under ESFR Heads

    While FM doesn't call them heat collectors, that's effectively what they are doing. You have the choice of installing such to form a solid continuous flat obstruction such that the heat will collect and the sprinkler activate or else space the sprinklers at 4' spacing under a non flat, non solid...

    sprinkler head

    I think it might be a Multiple Jet Control Valve. Similar to one link this http://www.fireguard-uk.com/products/sprinkler_systems/multiple_jet_control_valve.htm

    heat treat facility

    Would seem as long as the dog houses are heated then the feed main to the dog houses could be heat traced per NFPA 13 2013 8.16.4.1.3. If the heat tracing is just protecting feed mains then my understanding is that the heat tracing just has to be approved. If the heat tracing is protecting...

    Sch 7 pipe and other thinwall pipe

    FM 3-0 Section 3.2 still allows a C Factor of 120 for Galvanized while only allowing 100 for black steel. FM 2-0 Section 2.5.2.5 also states where galvanized or stainless pipe must be used (black steel only allowed on dry pipe with inert gas btw). FM have however done a very intensive technical...

    FM Global and the allowed coverage area of a sprinkler system - any changes recently?

    cdafd (Specifier/Regulator)1 Feb 18 00:41 I don’t know. If your lines are at say 20 feet and you pipe down for the valve,, Will you really get air out?? Copied your response to the other thread here cdafd. I would think you'd get air, then some spluttering, a somewhat steady stream of...

    Sprinkler ordinary temperature selection criteria

    Think you're on the wrong thread cdafd :) Will respond on the other one.

    FM Global and the allowed coverage area of a sprinkler system - any changes recently?

    I could see some benefits to the manual configuration. For the Automatic type they would have to be located at the high point which may be inaccessible for servicing in the future. Also, if you really wanted to get all (or at least most) of the air pockets out you'd end up with multiple Auto...

    FM Global and the allowed coverage area of a sprinkler system - any changes recently?

    FM 2-1 (Prevention and Control of Internal Corrosion in Automatic Sprinkler Systems) Section 2.3.1 has 'recommendations' for new sprinkler systems that also mention Air Vents such as the datasheet cdafd linked to. However in FM 2-1 it looks for "... means for air release at the highest point of...

    FM Global and the allowed coverage area of a sprinkler system - any changes recently?

    While there isn't a set ft2 area limitation FM 2-0, Section 2.4.1 and 2.6.4 have wording addressing the limitations of system size. i.e. (a) hydraulically works (b) Water flow alarm initiates within 60 seconds and also (c) if local code has requirements that the local code must be followed. If...

    Fire Inspection report software

    A while ago since I looked at it but when I did I was impressed with Onsite. https://onsitesoftware.com/fire-sprinkler-inspection/

    Moving clouds

    Haven't done one myself but initial thought would to see if possible to apply NFPA 13 2013 Section 22.19 (leads to NFPA 140)? Loosely put would mean EH2.

    Pump requirements for pulling water from pond

    Are there hydrants being fed from the loop (which as I understand is being fed from the vertical turbine). If so I would think that the vertical turbine should be UL Listed. I would see this a being no different that any installation requiring a fire pump as NFPA 24 2015 section 5.6 requires...
