Fire-resistant telecommunications cable YnTKSY 4x2x0.8 TN0005

Fire-resistant telecommunications cable YnTKSY 4x2x0.8

This cable is designed for permanent installation in fire alarm systems. Engineered for reliability and safety, it performs optimally in public buildings, industrial facilities, and any location requiring high fire resistance and stable signal transmission. It is used for connections between central alarm units and detection devices (sensors, linear modules) as well as smoke extraction and evacuation systems.

Construction and Application

The YnTKSY 4x2x0.8 cable consists of eight copper conductors, twisted in pairs to reduce interference. Each conductor is insulated with PVC, and the entire cable is protected by an outer sheath made of fire-resistant PVC. This construction ensures not only mechanical durability but, above all, safety during a fire—it limits flame spread and minimizes the emission of toxic gases. The cable complies with EN 60332-1-2, confirming its flame-retardant properties.

Applications include:

• Connections in fire alarm systems (FAS)
• Transmission of control and alarm signals
• Powering FAS devices
• Installations in public, industrial, and residential buildings
• Smoke extraction and evacuation systems

Key Features and Benefits

• Fire Resistance: The outer sheath, made of high-fire-resistant PVC (EN 60332-1-2), ensures safety during fire events.
• Reliable Signal Transmission: Twisted conductor pairs minimize electromagnetic interference, guaranteeing stable transmission of alarm signals.
• Durability: Robust construction with copper conductors ensures long-term operation even under harsh environmental conditions.
• Flexibility: Enables easy installation and routing in various configurations. Minimum bending radius: 10x cable diameter.
• Wide Operating Temperature Range: Suitable for operation between -40°C and +70°C, making it appropriate for both indoor and outdoor applications (with adequate protection).
• Electrical Parameters: Loop resistance of 75 Ω/km (for 0.8 mm² cross-section) ensures efficient signal transmission over long distances.

The YnTKSY cable guarantees safety and reliability in fire alarm installations—the trusted choice for professional installers and end users alike. Complies with LVD 2014/35/EU and holds CPR certification.
