Can low-voltage wiring be routed through fire cable trays
This means routing must be through dedicated, fire-resisting cable support systems – no sharing trays. Segregation of Power and Signal Cables: Power (high-voltage) and signal (low-voltage) cables should be routed separately, using dedicated trays to minimize electromagnetic interference. I was always under the impression that fire alarm wiring could not be in the same cable tray as other low voltage cabling. Where used, cable management systems shall be one or more of the following types: (i) conduit systems classified as non-flame propagating according to BS EN 61386 (ii) cable trunking systems and cable ducting systems classified as non-flame propagating according to BS EN 50085 (iii) cable tray and. This guidance covers the routing of secondary supply cables from a life safety generator to the ATS (Automatic Transfer Switch), and the final equipment with reference to: The goal: clarify requirements for the diverse cable routing and maintain circuit integrity under fire conditions for systems. Cable trays are a good choice for installations that may require future upgrading.
