Fire Alarm Cables | Halogen-Free, Flame-Retardant Safety Wiring Solutions

ETK Kablo’s Fire Alarm Cables are high-performance low-voltage signal transmission cables engineered for fire detection and alarm systems. Designed for environments requiring flame retardancy, low smoke emission, and electromagnetic compatibility (EMC), they ensure uninterrupted signal flow during critical emergency operations.
Our product range includes industry-standard J-H(St)H and J-Y(St)Y constructions, fully compliant with VDE, EN, and IEC standards—ideal for alarm loops, evacuation systems, sensors, and emergency communication lines.

Technical Construction and Design

ETK Kablo fire alarm cables are built with solid bare copper conductors for long-term conductivity and low resistance. Common conductor diameters range between 0.6 mm and 0.8 mm, arranged in twisted pairs to reduce crosstalk and maintain signal integrity across complex networks.

Each conductor is insulated with either halogen-free or PVC compounds based on project requirements. The J-H(St)H series features halogen-free flame-retardant insulation that produces minimal smoke and no corrosive gases, while J-Y(St)Y cables use PVC for cost-effective solutions where halogen-free materials are not mandated.

A collective Al/PET (aluminum-polyester) foil shield with a tinned copper drain wire provides full 100% coverage against EMI/RFI interference. This shielding ensures stable data transmission in power distribution zones, control panels, and mixed electrical environments. Outer sheaths are available in red (J-H(St)H) or grey (J-Y(St)Y), using flame-retardant PVC or halogen-free compounds for enhanced durability.

Signal Integrity and Electromagnetic Protection

In modern fire alarm and evacuation systems, reliable communication between detectors and control panels is critical. ETK Kablo’s shielded cables ensure low attenuation and noise immunity even in high-interference zones. The twisted pair structure maintains balanced impedance, ensuring precise signal transmission in addressable fire alarm systems and intelligent safety networks.

Fire Safety and Material Performance

The J-H(St)H series complies with IEC 60332-1 for flame retardancy, IEC 60754-1/2 for halogen-free content, and IEC 61034 for low smoke emission. These materials limit toxic gas release and ensure visibility during evacuation, while the flexible thermoplastic outer sheath provides easy installation without compromising fire performance.

For standard indoor applications where halogen-free materials are not required, the J-Y(St)Y series provides a robust and economical solution, maintaining essential flame propagation standards under EN 50200 and equivalent norms.

Application Areas and Industries

ETK Kablo’s fire alarm and signal cables are designed for fixed indoor installations in fire-safe environments. Typical applications include:

• Commercial buildings – fire detection, public address (PA), and emergency signaling.
• Hospitals and healthcare facilities – nurse call systems, evacuation triggers, and monitoring networks.
• Tunnels, rail systems, and airports – halogen-free, low-smoke cabling ensuring safe evacuation.
• Factories and data centers – shielded cables maintaining EMC stability during operations.
• Public institutions and educational facilities – integrated with BMS, HVAC, and emergency lighting systems.

Product Range and Options

Available in 2x2x0.8 mm² to 10x2x0.8 mm² constructions, ETK Kablo’s J-H(St)H and J-Y(St)Y cables can be supplied with customized shielding, sheath materials, and CPR ratings.
J-H(St)H models feature halogen-free insulation with collective aluminum shielding and red sheath color.
J-Y(St)Y variants use PVC insulation and grey sheaths, offering cost-effective solutions for general-purpose communication lines.

Quality Assurance and Certification

Manufactured under ISO 9001 certified systems, ETK Kablo’s fire alarm cables undergo rigorous testing for:

• Conductor resistance and insulation integrity
