Do low-voltage power and fire protection cables share the same cable tray
While it is technically possible to run power and low-voltage cables in the same tray under strict conditions, segregation or shielding is strongly recommended to ensure safety, compliance, and system reliability. While all data cable is ran within cable tray, about 20% or so of the fire alarm cable is sharing the same tray. 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 -. Maintaining proper separation between power, data, and limited energy cabling is foundational to system performance, safety, and code compliance. 48 Conductors of Different Circuits in the Same Cable, Cable. 760. A power-limited tray cable (PLTC) is covered by Article 725 and is a factory assembly of two or more insulated conductors rated at 300 volts, enclosed in a non-metallic jacket.
