Frequently Asked Questions
What makes the Belden 658AFS plenum-rated CMP cable suitable for access control systems?
The 658AFS is specifically designed for plenum environments where fire safety is critical. Its Flamarrest insulation and jacket meet NFPA 262 and UL 1666 standards, ensuring it won't contribute to smoke or flame spread in air-handling spaces. The overall Beldfoil shield protects access control signals from electromagnetic interference, maintaining system reliability in complex building installations.
Can I use this composite cable for both power and control applications?
Yes. The 658AFS composite cable features multiple conductor gauges (18 AWG and 22 AWG) that support both power-limited control circuits and signal transmission. This versatility makes it ideal for integrated access control systems that require both power distribution and data signaling in a single cable run.
Is the Belden 658AFS compliant with building codes?
Absolutely. The plenum-rated CMP rating ensures compliance with building codes that require fire-safe materials in HVAC plenums and air-handling spaces. The Flamarrest insulation and low-smoke characteristics meet all major fire safety standards, making it the right choice for code-compliant security installations.
What is the advantage of the Beldfoil shield in access control applications?
The overall Beldfoil shield provides comprehensive EMI/RFI protection, preventing electromagnetic interference from disrupting access control signals. This is especially important in buildings with multiple electrical systems, ensuring your security infrastructure operates reliably without signal degradation.
