Do fire protection and low-voltage electrical systems share the same cable tray
The most effective method is to utilize separate, dedicated cable trays or metallic conduits for each system. The metal conduit or raceway acts as a Faraday cage, shielding the conductors inside from external electrical noise and protecting them from mechanical damage. The commissioning agents for the project have recently told us that this is against code, however in speaking with our fire alarm subcontractor they do not believe that to be the case -. Power-Limited Fire Alarm (PLFA) circuits, which make up the majority of modern fire alarm systems, are generally permitted by the NEC to share a cable tray or raceway with communications circuits, provided certain conditions are met. You can install two or more PLFA circuits. Code violation alert: Fire sprinkler piping is not a cable pathway. Life safety risk: Sprinkler lines must remain. Maintaining proper separation between power, data, and limited energy cabling is foundational to system performance, safety, and code compliance. Separation isn't just an EMI precaution — it protects signaling, reduces rework, and ensures pathways meet inspection expectations across risers.
