Re: Floating Dock

Hello Charles, See if I can get all the answers in this email: It is schedule 40 now and had to be centered in the floating section to keep it level, This will be 4 feet off center. There is no handrail on the floating section so it will be mounted to the deck with 2' risers to the hose valves.

Re: Pressure Reducing Valve on a Balancing Calculations

Hi Jerry, Have you considered using a pressure sustaining valve on the supply side of the pump? It has the effect of limiting the pressure at low flow, then opening up to full pressure at high volume. I believe you would need to locate the valve upstream of the pump outside of the pump house to

Pressure Reducing Valve on a Balancing Calculations

I have a Fire Pump feeding a HiEX foam and Wet System. The start-up churn on the pump will cause the pressure to go over 175 psi so we are putting a pressure reducing valve on the wet feed side of the discharge. I'm not sure how I balance this system anymore due to the PRV. The valve will be se

I've never actually installed it myself. Priced it once. But I see it all over. Yes, typically under the floating docks feeding hose valves from below. John Irwin Critical System Solutions Sprinkler Construction Manager 813-618-2781 jir...@criticalsystemsolutions.com

Floating Dock

Hello Sprinklerforum, Looking for suggestions for pipe to use on top of a floating dock for the Manual Dry standpipe. We had pipe under it but due to structural failures of the dock the pipe is now in 3-5 feet of muck in the bottom of the river. Looking to run the pipe on top of the dock. Ther

Re: Unsprinklered spaces in strip malls

Replying to SL's comments re: Individual shut off and flow switches to individual tenant spaces in larger malls. True malls, larger than 50k sf have required active smoke control. Automatic detection is required. This may be by smoke detectors, or by flow switches configured as observed by SL.

RE: Unsprinklered spaces in strip malls

In a perfect world, they are not getting an occupancy permit on the “vacant spaces”. In that case it could be looked upon as no occupancy, no fire hazard. If the spaces are vacant with no combustible load and no occupancy, it behaves much like a noncombustible concealed space above the ceiling.

RE: Unsprinklered spaces in strip malls

Because if it’s a non-combustible building and the owner isn’t trying to obtain a certificate of occupancy for the rough tenant suites, then they can request final inspection on the common and back-of-house areas and defer the tenant suites. It’s actually a low-drama scenario at the statutory l

Re: Unsprinklered spaces in strip malls

I've worked on those kinds of malls and typical up here is the bulk mains running in the back of the spaces with cross-main locations on either separate control valves or just flanges, with white painted frying pans on chains, but I thought the conversation was about strip malls. On Thu, Feb 16, 2

RE: Unsprinklered spaces in strip malls

Good point. There are two basic ways to sprinkler a multi-tenant mall: run mains and branches throughout with capacity for TI’s or run just mains and let each tenant build their own system by cutting into the main with a saddle. Over the years, I’ve worked on a couple of regional-sized mall

Oh ye of little faith: "could be interpreted” and “alluding” indeed. As doubting Ron stated, in a non-separated mixed use, the most demanding applies throughout. In a separated, mixed occupation, it depends of the occupancies, type of construction, height, application of trade-offs etc. It’s

It's totally conceivable that based on the Building Code occupancy classification of areas that there would be leased spaces that would not require an automatic fire sprinkler system. However it is highly unlikely that during construction of the building that the owner would provide the proper

Re: Unsprinklered spaces in strip malls

I think the building code would allow, or could be interpreted, to mean what Roland is alluding to in his short post. Then the same with Steve. Is the AHJ calling for sprinklers per occupancy definitions in the building code? You can make a case that in a mixed use you need a OH2 in the auto-parts

Careful with that claim Shawn. NFPA 13 does NOT require a building or part of a building to be furnished with sprinklers, just as NFPA 14 doesn't require standpipes in buildings and NFPA 20 doesn't require pumps on FP systems, etc., etc. The adopted building code requires sprinklers in buildi
