Does anybody know if there is a specific regulation regarding the coexistence of alarm cabling (fire/buglar/etc.) in a cable tray with data/voice cabling?
I have never seen this done on commercial installations until now; generally, the alarm guys pick a totally independent path, including seperate conduit to the panel location.
My concern in two-fold: I have a situation where the alarm cablers wove between some of the communication cables in and out of the tray. They are running both parallel and right-angle to the communication cable. My first concern is EMI affecting the data cabling, second is the possibility of damage resulting from pulling across the data/voice cables.
I thought I had heard or read somewhere that there was a specific NEC reference on this. Or would this be a jurisdictional issue?
