another thing worth mentioning is AHJ. Sometimes depending on your local regs you may have to follow IMC code and not NFPA.
I see a bunch of guys just cutting the sample tubes to fit and not paying attention to the holes in the tubes. I didn't catch you mentioning anything about the number of holes in the sample tube. Is there somewhere in NFPA 72 that address this?
very helpful thank you
You're welcome!
Great video. Just out of curiosity, what is the code on requirement for holes in the sample tube for a 22 inch duct?
Can you mount a duct detector inside the air unit at the beginning of the supply?
How many duct detectors can be installed in a loop.?
That entirely depends on the manufacturer of the parts. There is not a code limiting that.
