Class A fire alarm system

[Donike]

I would like to know the required conduit spacing for the network loop conduits .the spacing for channel A and B are 4' horizontal and 1' vertical. Class a system has a redundancy circuit ,and are wondering once you leave the fire alarm closet or room,is there a minimum spacing of the in loop and out loop?

IIRC, you are allowed to run the two conduits more or less together for up to 10' outside the cabinet.
