RE: Class I standpipe - high pressure zone

Just saw this ... DeWayne, we recently did a 500 foot tall building with a single zone. I'm not sure what your specifying engineer is thinking, but the cost of fire protecting this building went way, way up when he made the decision to specify two zones. Steve Original message -

RE: Class I standpipe - high pressure zone

Assuming your high zone FDCS are tied to the common feed mean that supplies the two guys on risers, you do not need a second interconnection. Or at least that's my best guess, without seeing a plan or knowing exactly how high the building is. My opinion only, Steve Original message

Just a bit of an update: Per NFPA24-2016 & NFPA 13-2016, Section 10.1.4.1 10.1.4.1 Underground piping shall be permitted to extend into the building through the slab or wall not more than 24 in. (600mm). A.10.1.4.1 Where nonmetallic underground piping is provided a

RE: Class I standpipe - high pressure zone

There are separate fire department connections for the low and high pressure zones. There is a common supply for the high pressure zone in the basement which feeds two vertical risers each individually controlled by butterfly valves. What I am asking is if these two feeds must be looped together

RE: PVC FOR INCOMING SERVICE SUPPLY

The problem with PVC or any non-metallic pipe is that if they are not listed for above ground service you may need to transition from the plastic to a metallic pipe above the slab. Check the manufacturer's listing for installation restrictions. At fire temperatures the plastic could be structur

Depends on the egress distance also. If 400 ft is used rather than 250 ft. Then smoke vents are required. Sent from my iPhone > On Mar 24, 2016, at 12:09 PM, Reed A. Roisum, SET > wrote: > > I don't know of that requirement. > > Section 910 of the IFC says "where installed in buildings equip

I don't know of that requirement. Section 910 of the IFC says "where installed in buildings equipped with an approved automatic sprinkler system, smoke and heat vents shall be designed to operate automatically." The commentary explains that the fusible link temperature should be coordinated wi

Cesar, If I read your inquiry correctly the data you need is most likely in FM Global Data Sheet 3-10, in Table 1. It looks as though they don't make a distinction in that data sheet based on the type of occupancy. *Ken Wagoner, SET *Parsley Consulting*** *350 West 9th Avenue, Suite 206 *E

I recall reading somewhere that if you're using ESFR heads and there are roof vents present they need to be monitored and closed if there's an activation, correct? Can anybody tell me where I saw that :) Brian Harris, CET BVS Systems Inc. Sprinkler Division bvssystemsinc.com
