Alarm lines should be routed through fireproof cable trays
Use fire-rated cables with appropriate temperature ratings and install them in fire-rated pathways, such as fire-rated conduit or cable trays. Seal penetrations through fire-rated walls or ceilings with fire-rated caulk or sealant to maintain the integrity of the fire. This document outlines the key requirements for cable tray layout, installation, and fireproofing in industrial and commercial environments. Route Planning and Layout Principles Coordinate with Building Structure: Cable tray routing should align with architectural design, avoiding unnecessary. Scope: Firestopping for busway, cable trays, cables, and trunking passing through walls in enclosed electrical installations. Building control circuits associated with the fire alarm system, such as elevator capture and fan shutdown, must comply with Article 725 [760. 3. Cable trays hold the wires for things like power and communication. They seem like separate things, but they need each other to keep buildings safe.
