Hello all,

I'm creating shop drawings for a NYC MTA transit job and by contract I'm installing empty conduit for power and communications. My foreman is telling me that after the attacks on 9/11 by code you are not allowed to run fire alarm conduit on the same strut as other communications devices such as PA, LAN, Access Control, etc.? He wants me to show it on its own separate J-hook away from the main comm rack. Can anyone verify this for me and direct me to where in the code it says this (NFPA 70, 72).

Thanks in advance.
