Can fire protection and low-voltage electrical systems share the same cable tray

Can fire protection and low-voltage electrical systems share the same cable tray

Sharing the same cable tray or conduit with data cables increases the risk of mechanical damage and impairs fire resistance. While all data cable is ran within cable tray, about 20% or so of the fire alarm cable is sharing the same tray. 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. Poor segregation, inadequate fire resistance, or unsuitable fixings can compromise both system performance and occupant safety. YY, SY and CY cables are made to various manufacturers specifications but not governed by any National, European or International standard, hence these are not currently recognized in BS 7671:2018, Regulation 133. 1 of BS 7671:2018 requires every item of equipment to comply with the appropriate.
