1.5mm² Fire Resistant (FR) Cable – 2-Core, Low Smoke Zero Halogen (LSZH) Fire Alarm System Wire

The 1.5mm² Fire Resistant (FR) Cable is the standard wire for connecting essential life safety equipment, such as smoke detectors, manual call points (break glass), sirens, and emergency lights. In the event of a fire, this cable is designed not only to be flame-retardant but also to maintain circuit continuity for a specified period, allowing fire alarms to function and enabling safe evacuation.

Key Safety Features:

• Circuit Integrity: The insulation, often using special compounds like Mica Glass Tape or fire-resistant silicone rubber, ensures the cable continues to transmit power and signals even when exposed to direct flame and high temperatures (often tested to standards like BS 5839-1 and BS 6387 CWZ).

• LSZH Jacket: The outer sheath is made from Low Smoke Zero Halogen material. This is crucial because, in a fire, it releases minimal, non-toxic smoke and no corrosive halogen gases, which protects people’s escape routes (visibility) and prevents damage to sensitive electronic equipment.

• Conductor: Features solid or stranded copper conductors, providing low resistance for reliable power and signal transmission over distance.

This cable is mandatory for all new commercial, industrial, and high-occupancy building fire systems, ensuring compliance with local fire safety codes and best practices.

 Key Features

• Fire Resistance: Maintains circuit continuity under extreme heat and direct flame for a specified time.

• Low Smoke Zero Halogen (LSZH): Drastically reduces the emission of toxic fumes and dense smoke, improving visibility for evacuation.

• Conductor Size:  the standard size for most power-limited fire alarm circuits.

• Standard Compliance: Approved to international standards like BS 7629-1, BS 5839-1, and BS EN 50200 (often PH30/PH60/PH120 rated).

• Applications: Ideal for Fire Alarm Control Panels, Smoke Detectors, Sirens/Sounders, and Emergency Lighting.
