    Vane type flow switch on fire sprinkler system

    Does the system have a relief valve? Does some one manual turn on a pump to pressurize? Just a couple random thoughts.

    Single Building - Multiple Services and FDCs

    Thank you for the answers. I am in agreement that it is permitted to have multiple undergrounds and FDCs. But generally should not be done since it makes things more complicated.

    Single Building - Multiple Services and FDCs

    I am looking for another opinion on whether the Fire Department Connections need to be "interconnected" when a large building is supplied by more than one underground service/riser. The case I have in mind is a large warehouse (200,000 sq ft) with risers at opposite ends as was commonly done in...

    NFPA 13D Pex as a stand alone system????

    This is a very interesting idea. So can one put a single hose bib valve on the system and call it a "multipurpose" system? I will have to get a hold of my Reahau rep and do some more investigation.

    AutoCAD 2011 DWG to PDF plotting problems

    I have gone around and around on this issue over the years. The best solution I have seen posted yet is to first print to a DWF (i.e. publish) and then use AutoDesk Design Reviewer to convert the DWF to PDF using PDF995 or similar. Conversion is much faster and do not get all the bugs of AutoCAD.

    Slow Copy/Paste

    I will make a guess that you are using the 2008 version. This had a bug with the plot scales going crazy. See http://www.thecadgeek.com/blog/2007/09/26/perpetual-annotation-scale-list/ Command: -SCALELISTEDIT Enter option [?/Add/Delete/Reset/Exit] <Add>: Reset Reset scale list to defaults...

    Fire Pump Phase Reversal

    It has been my experience that most fire pump controllers have a button inside the panel you can push to simulate the "phase reversal" condition. This is addition to making sure it runs in the right direction as previously noted.

    Pipe or tube development about a line?

    I have used 3Dtube before at http://freecadapps.mcadcafe.com/swdetails.php?page=search&value=&orgvalue=&review=1920&rowcolor=fce08d Works OK. You have to select plines and then just give it the diameter you want to create.

    Outlook email folders and be organized

    If you have Adobe 7 or newer it adds a PDF button in Outlook that will convert a folder to a single PDF file. The PDF file creates bookmarks that automatically sort by date/subject/sender. All attachements to the emails are also stored in the PDF. I have done several folders with 2,000 emails...

    Water Flowing Methods

    Two issues. First to Ixaon's post about a better way. I personnaly always require a flow meter loop. That way no water is required to be flowed except during commissioning and the 5-year test. I know some people do not like the flow meters, but I believe that properly calibrated they are...

    Power Supply to Auto Transfer Switches

    No sure I understand your question exactly. However, you are only allowed to have one disconnect between the source and controller. I think you want to look in the National Electrical Code. Couple references below. NFPA 70 - National Electrical Code® - 2005 Edition 695.3 Power Source(s) for...

    Sprinklers for diesel pump house

    Some where in NFPA 20 it says that to have a fully sprinklered building, BOTH the pump house and main building must be sprinklered. Sorry don't have the code book handy. And, I would definitely put a separate flow and inspectors test on the pump house bldg.

    Sprinkler Supply line

    NFPA 13 (2002 edition) A.15.2.1 Care should be taken in making water tests to be used in designing or evaluating the capability of sprinkler systems. The water supply tested should be representative of the supply that might be available at the time of a fire. For example, testing of public...

    Air Comp plugged into wall outlet

    There are UL-Listed air compressors that must be hard wired. However, I do not believe that the code requires them. As stated, probably to not good practice. However, I don't blieve it is prohibited. I will have to check with some Elec Engineers to see if there is a NEC requirement. UL Fire...
