LSZH Fire Alarm Cable Z1OZ1-K (AS) 300/500V Screened, Halogen-Free Fire Detection Cable for Public Buildings
Product Overview
The Z1OZ1-K (AS) LSZH Fire Alarm Cable is a low-voltage, halogen-free, and fire-performance cable specifically engineered for fire detection and alarm systems in public and safety-critical environments. Designed in accordance with UNE 211025, this cable ensures reliable signal transmission while maintaining strict fire safety and environmental standards.
It is particularly recommended for installation in public buildings, where safety, low smoke emission, and non-corrosive behavior during fire are essential. This cable is not intended for direct connection to power supply networks or low impedance sources, ensuring its dedicated use in signaling and alarm circuits.
Key Features and Advantages
1. Enhanced Fire Safety Performance
Flame non-propagation: EN 60332-1 / IEC 60332-1
Fire non-propagation: EN 60332-3 / IEC 60332-3 / EN 50399
CPR classification: Cca-s1a, d1, a1 (EN 50575)
This ensures that the cable significantly reduces fire spread and contributes to safer evacuation conditions.
2. Low Smoke & Zero Halogen (LSZH) Design
Halogen-free: EN 60754-1 / IEC 60754-1
Low corrosive gas emission: EN 60754-2 / IEC 60754-2
Smoke emission: EN 61034 / IEC 61034 (light transmittance > 80%)
These properties minimize toxic fumes and improve visibility during fire incidents, protecting both people and equipment.
3. Reliable Electrical Performance
Rated voltage: 300/500 V (low voltage)
Ensures stable signal transmission for fire alarm and detection systems.
4. Robust Thermal Characteristics
Maximum operating temperature: 70°C
Maximum short-circuit temperature: 160°C (max. 5 seconds)
Minimum service temperature: -15°C (static, with protection)
Suitable for a wide range of indoor installation environments.
5. Durable Mechanical & Environmental Performance
Minimum bending radius: 10 × cable diameter
Water resistance: AD3 (sprays)
Chemical & oil resistance: Acceptable
Ensures durability under typical installation and operational conditions.
