Color of fire cable trays

Red is the preferred color for fire system cables, while cable trays for fire-resistant circuits may follow standard color codes or be left neutral, with fire-resistant properties indicated by certification.

Color Coding for Fire Cables

For fire alarm and fire-resistant circuits, red is the recommended color for the cables themselves to distinguish them from general electrical wiring, ensuring quick identification during maintenance or emergencies. This color convention helps prevent accidental disconnection or interference with critical fire safety systems.

Cable Tray Considerations

Cable trays carrying fire-resistant or fire alarm cables do not have a strict regulatory color requirement. They may follow general cable tray color codes, such as orange for critical circuits, or remain neutral (e.g., metallic or white) while the cables inside are red. The key is that the tray should not be easily confused with other non-fire circuits, and labeling or color bands can be used to enhance identification.

Fire-

Resistant Tray StandardsFire-resistant cable trays are designed to maintain circuit integrity during a fire. Products like Cablofil fire-proof trays are tested according to standards such as DIN 4102-12, ensuring they can withstand high temperatures for 30, 60, or 90 minutes. These trays are suitable for low and high voltage cables in industrial, power, and infrastructure applications, and their fire-resistant properties are more critical than the tray color itself.

Practical Recommendations

Use red cables for all fire alarm and fire-resistant circuits. Cable trays can be neutral or follow critical circuit color codes (e.g., orange) but should be clearly labeled. Ensure trays and cables meet fire-resistance standards appropriate for the installation environment.

Consider using fire-resistant coatings or tape for additional protection in sensitive areas. By following these practices, fire system circuits remain easily identifiable, compliant with safety standards, and protected against fire hazards.
