What is the best reference to cite for how Indiana interprets dual path communication for commercial fire alarm monitoring, and where can it be found?
Either thier written requirement, or NFPA 72.
How do they interpret it?
Does Indiana have a state wide adopted code, or can each city adopt whatever code they want?
Indiana has a statewide code, and I believe they reference the 2013 version of NFPA 72. I'm just looking for the amended language that describes what the state accepts for dual path communication.
May be in the link above?
Should be either a cell, what I call it, with no 2nd line.
Or Cell with a land line back up.

Maybe just call one of the bigger cities and ask the question
Is it somewhere in all this stuff??
