NFPA 70 has the requirements for cable supports. The NEC does not distinguish supports of fire alarm cable vs other systems so j-hooks or whatever supports are used are regulated by NFPA 70 not NFPA 72.
Typical spacing for cable or conduit supports is 10-ft, but not everything. For instance...
I'm still waiting for a project where "fudging it" actually gets me ahead on something/anything...but every time something is fudged it ends up costing me and the project much more than if the drawings were developed properly. Taking that a step further, if someone under me fudges something on...
Am I reading your response correct Mr Stookey...my question (or approach) is sleazy and/or incompetent? Or are you meaning something else. Also, this has nothing to do with H or I or any other occupancy group...simply the intent/expectation of the ICC.
NFPA (in various standards) makes the following (or similar) statement in the Scope section: "The values presented for measurements in the Code are expressed with a degree of precision appropriate for practical application and enforcement. It is not intended that the application or enforcement...
I'm looking for custom painted sprinklers...do you know any manufacturer's that have a listed SSP that can be ordered in various colors? I know I can get cover plates painted by Tyco, but not sure about the sprinkler themselves.
I have an Architect trying to design a fairly complicated and...
I see these types of valves used for hoistways. Maybe it'll help you a little.

Does your facility have to meet Joint Commission, CMS, COLA/CLIA or other requirements? Or are you simply operating within the NFPA world? Each of these organizations have their own modifications to the Standards which may affect the answers you get?
Based simply on the Life Safety Code, I...
We're working on a new US Gov't project with a SCIF and following UFC 4-010-05 we are required to have a dielectric union in the SCIF on the sprinkler pipe.
Wondering how others are handling this. We've used a section of CPVC through the SCIF wall with black steel on either end of the CPVC for...
Keep in mind that some heat trace systems do not report failures in the cable...so you can lose heat without knowing. I would suggest a system that monitors the integrity/functioning of the heat trace cable so that when there is a failure it alerts someone instead of failure and freezing pipe...
In my opinion this would not be a good software to use if you plan on doing larger systems or lots of projects. There are better software packages that are tailored to sprinkler design. You can use LT to do design work, but I suspect you'll find it much more cumbersome and labor intensive than...
