If you could look at the image you will see the EMT feeding 120 to the fire alarm panel goes through the trough.

My question is the 14/2 that goes out to feed the "bell"....does that also need to be isolated from all the fire alarm cables in the trough. Thanks

If the fire alarm system is a power limited system, (not even sure if they make non-power limited fire alarm systems anymore, then the 120 volt bell circuit will need to be isolated from the power limited fire alarm cables. 760.136.
