Life safety systems are critical components in modern buildings and infrastructure, designed to protect occupants during emergency situations such as fire incidents. These systems—including fire alarms, emergency lighting, smoke extraction, and evacuation controls—must remain operational even under extreme fire conditions.
Fire resistant cables play a vital role in ensuring continuous power and signal transmission, allowing life safety systems to function when they are needed most.
Unlike standard power cables, life safety systems require cables that can:
Maintain circuit integrity during fire
Withstand high temperatures, flame exposure, and mechanical shock
Support emergency operation until safe evacuation is completed
Failure of cabling during a fire can lead to system shutdowns, delayed evacuation, and increased risk to human life.
BS 6387 CWZ is one of the most widely recognized standards for fire resistant cables used in life safety applications.
It verifies cable performance under three critical conditions:
C (Fire Resistance) – Circuit integrity at 950°C
W (Water Resistance) – Operation during fire with water spray
Z (Mechanical Shock) – Resistance to impact during fire exposure
Cables meeting BS 6387 CWZ ensure reliable operation of life safety systems in real-world fire scenarios.
Fire resistant cables compliant with BS 6387 CWZ are commonly used in:
Fire alarm and detection systems
Emergency lighting and exit signage
Smoke control and ventilation systems
Evacuation voice communication systems
Critical control and monitoring circuits
Similar safety requirements can also be found in hospitals and high-rise buildings, where continuous operation of life safety systems is essential for occupant protection.
Our fire resistant cables are engineered to support life safety systems by maintaining electrical integrity during fire exposure, helping ensure:
Reliable emergency operation
Compliance with international fire safety standards
Reduced risk of system failure during evacuation
