Introduction
Fire curtains have evolved significantly over the past three decades, and nowhere is this evolution more evident than in Coopers Fire’s engineering and commitment to excellence. As the foremost standard governing active fire curtain barrier assemblies, BS 8524-1 sets the benchmark for performance, durability, and safety. Coopers Fire, a pioneer in fire curtain technology, has played a pivotal role in shaping this standard. Through superior mechanical and electromechanical engineering, extensive testing, and an unwavering dedication to large-scale solutions, Coopers Fire has become the global leader in fire curtain technology.
The Critical Importance of BS 8524-1
BS 8524-1:2013 is the most rigorous fire curtain standard available, far surpassing alternative standards such as EN 1634-1, EN 12101-1, and UL 10B. Unlike these standards, BS 8524-1 does not merely assess fire resistance—it ensures complete system integrity, operational reliability, and performance longevity. This distinction is why Coopers Fire has committed to extensive in-house development and testing, setting them apart in the industry.
Key aspects that make BS 8524-1 superior include:
- Fire Resistance: Fire curtains tested under BS 8524-1 achieve E180 EW90 classifications, offering 180 minutes of integrity (E) and 90 minutes of radiation control (EW) for optimal fire compartmentation.
- Durability & Cycle Testing: Unlike EN 1634-1, which requires just 25 test cycles before fire resistance testing, BS 8524-1 mandates 500 preliminary cycles followed by an additional 25 cycles before fire testing to simulate real-world wear and tear.
- Electromechanical Reliability: BS 8524-1 requires rigorous fail-safe operation testing, ensuring gravity deployment under all circumstances, including power failure scenarios.
- Impact & Pressure Resistance: The standard mandates performance under differential pressures up to 20Pa, making it ideal for high-risk environments.
- Integration with Fire Safety Systems: The requirement for BMS (Building Management System) integration ensures real-time monitoring and status reporting.
Innovative Motor & Control Technology
Coopers Fire’s dedication to superior electromechanical solutions is exemplified in its motor and control technology. The Variospeed 6 ERU-CG system utilises 24Vdc permanent magnet motors fitted with an internal electromagnetic brake. This system ensures that the fire curtain remains securely in its retracted position without power consumption, prolonging motor life and ensuring fail-safe deployment.
Key advantages include:
- Gravity Fail-Safe Compliance: Even in cases of complete power failure, the system ensures controlled descent.
- Integrated Short Circuit Protection: Prevents motor damage and guarantees operational reliability
- Phased Descent Mechanism: Allows the curtain to lower in a controlled manner, preventing sudden deployment hazards.
- Soft-Set Functionality: Reduces voltage during the final 500mm of ascent, ensuring a smooth return to the retracted position.
- Battery Backup Unit (BBU): Ensures continued functionality in the event of power failure.
- Alarm Integration: Automatic activation upon fire detection, providing enhanced fire safety compliance.
Fire Performance & Compliance Beyond Standards
Coopers Fire has committed itself to manufacturing and rigorously testing fire curtains that exceed minimum compliance thresholds. Its products do not just meet BS 8524-1—they define what is achievable within the framework of this standard. The company’s fire curtains undergo comprehensive testing that includes:
- Radiation Control (EW) Classification Testing ensuring reduced heat transfer across compartments.
- BS 476-6 & BS 476-7 Fire Propagation Testing verifying minimal flame spread.
- Smoke Leakage Testing achieving leakage rates of less than 3m²/m/h, critical in smoke control applications.
- Environmental Durability Testing to assess long-term material integrity under extreme temperatures and environmental conditions.
- Structural Integrity Testing ensuring system stability under fire and smoke conditions.
- Component Durability Assessment ensuring motor longevity and continued performance under operational stress.
Why BS 8524-1 Outperforms Other Fire Curtain Standards
- Superior Durability: Unlike EN 1634-1, BS 8524-1 ensures systems undergo extensive operational cycling before fire resistance testing, proving their longevity in real-world conditions.
- Enhanced Safety Performance: The inclusion of pressure resistance testing and mandatory fail-safe operation guarantees the reliability of fire curtain systems.
- Comprehensive Certification: Fire curtains tested under BS 8524-1 undergo far more rigorous assessments, including integrity, radiation control, and environmental durability.
BS 8524-1 Cycle Testing & Large-Scale Certification Commitment
Coopers Fire ensures that every fire curtain undergoes comprehensive testing across all sizes, validating system performance under the rigorous BS 8524-1 cycle testing requirements. The company has committed to testing large-scale configurations to the same standard as smaller ones. This means that whether a curtain is designed for a 1m x 1m opening or a 20m x 2m opening, it undergoes the same 500 operational cycles, followed by an additional 25 cycles before fire testing, proving its durability and reliability.
