Access System Composite Optical Cable

Composite access control cables integrate multiple conductors for power, data, and monitoring in a single jacket, streamlining installation and enhancing security system performance.

Overview

An Access System Composite Optical Cable is designed to combine multiple conductor groups within a single outer jacket, supporting all essential functions of modern access control systems . These cables are commonly used in commercial buildings, schools, hospitals, and government facilities where security and efficiency are critical . By consolidating power, signal, and monitoring lines, they reduce the need for multiple cable runs, saving time and labor during installation .

Typical Structure

Composite cables usually include several distinct elements:

• Lock Power Conductors: Four 18 AWG conductors provide sufficient current for fail-safe and fail-secure electronic door locks, minimizing voltage drop over long runs .
• Card Reader Communication Pairs: Three twisted pairs of 22 AWG conductors support proximity, magnetic, or biometric readers . Shielded pairs may be included to reduce electrical noise interference .
• Door Contact Monitoring: Two 22 AWG conductors detect whether doors are properly closed and secured .
• Request-to-Exit (REX) and Auxiliary Functions: Four 22 AWG conductors handle push buttons, motion sensors, and other egress devices .

Color-coded jackets simplify identification: gray for lock power, orange for card reader pairs, white for door contacts, and blue for REX connections .

Key Features and Benefits

• Single-Pull Efficiency: Bundling power and signal conductors reduces conduit congestion and installation time .
• Fire Safety Compliance: Many cables are Low Smoke Halogen Free (LSHF) or CPR-compliant, minimizing risk to personnel and property in case of fire .
• Durability and Flexibility: Stranded copper conductors and plenum-rated jackets handle bends and door movements while maintaining reliable performance .
• Installation Aids: Features like SmartWire Glide Technology® reduce pulling friction, and footage markers simplify measurement and reduce waste .

Applications

These cables are ideal for:

• Commercial and retail buildings
• Educational institutions and campuses
• Hospitals and healthcare facilities
• Government and municipal offices

They support door locks, card readers, REX devices, motion sensors, and other access control peripherals, providing a streamlined, reliable solution for integrated security systems .

Conclusion

Composite access control cables offer a practical, efficient, and safe solution for modern access systems by combining multiple conductors in a single jacket, simplifying installation, reducing labor, and ensuring reliable operation of security devices across a facility .
