The B2ca-s1a,d0,a2 Security & Alarm Cable is designed for fixed installation in security, alarm, access control and low-voltage communication systems where enhanced reaction-to-fire performance is required.
It is suitable for security and building infrastructure applications including intrusion detection systems, security alarm panels, access control systems, door and gate control, emergency communication and other low-voltage signalling circuits.
The cable is particularly suitable for buildings and construction works where fire safety, smoke control and continuity of security-related signalling are important considerations.
Typical applications include commercial buildings, offices, hotels, hospitals, schools, public buildings, shopping centres, transport facilities, high-rise buildings, residential developments and other high-occupancy or safety-sensitive environments.
The screened construction provides additional protection against electromagnetic interference, supporting stable signal transmission in electrically demanding building environments.
High CPR reaction-to-fire performance with a target classification of B2ca-s1a,d0,a2.
Low Smoke Zero Halogen (LSZH) construction designed to reduce smoke and corrosive halogen-containing gas emissions during fire.
Enhanced flame-spread control for use in buildings where higher fire performance is required.
Shielded construction with aluminium/polyester foil and drain wire for improved electromagnetic interference protection.
Flexible annealed copper conductors for reliable electrical performance and convenient installation.
Designed for security and alarm signalling in fixed low-voltage installations.
Suitable for intrusion detection, security alarm, access control and building security systems.
Suitable for installation in commercial, public, residential and infrastructure buildings subject to applicable installation requirements.
Available in multiple core and conductor configurations to meet different security system wiring requirements.
Designed for European construction applications requiring cables with enhanced reaction-to-fire performance.

Higher Reaction-to-Fire Performance
B2ca belongs to the higher reaction-to-fire classes for cables under the European CPR classification system. It is designed for applications where stricter control of flame spread and heat release is required.
Low Smoke & Halogen-Free Construction
LSZH materials help reduce smoke and halogen-containing corrosive gases during fire, supporting safer conditions for occupants, equipment and emergency evacuation.
Designed for Security Systems
The cable combines fire-performance considerations with the electrical requirements of security and alarm signalling, making it suitable for modern building security infrastructure.
Suitable for Safety-Critical Buildings
B2ca cables are particularly relevant to buildings and construction works where higher fire safety performance is required, including public buildings, commercial facilities, healthcare, education, hospitality and high-occupancy environments.
