Security & Access Control BACnet | RS‑232/485 Shielded Cables
Windy City Wire manufactures SmartWire® low-voltage cables designed for reliable BACnet MS/TP, RS‑485, and RS‑232 communication in building automation, HVAC controls, and access control systems. Our portfolio balances electrical performance with installation efficiency, helping integrators and contractors deliver stable networks for controllers, readers, door hardware, and sensors across commercial and industrial facilities.
Every SmartWire cable in this category is engineered for clean signal transmission, with shielding options to reduce EMI/RFI, precise pair geometry for consistent impedance, and low-capacitance constructions for longer runs. Choose from plenum (CMP/CL3P), non‑plenum (CM/CL3), and direct burial options to match the jobsite environment, all manufactured in the United States and RoHS compliant.
Available across multiple conductor sizes—18, 22, and 24 AWG—and in 1 pair, 1.5 pair, 2 conductor, and 2 pair configurations, these shielded cables cover controller trunks, device drops, and panel interconnects for security and access control. If you need to standardize on jacket colors or stripes for fleet-wide consistency, our team can help configure a SmartWire solution for your next rollout.

Why spec Windy City Wire for BACnet and RS‑485/RS‑232
Whether you are designing an access control backbone, extending a BACnet MS/TP network, or integrating security devices with building automation, our shielded, low‑capacitance BACnet and RS‑485/RS‑232 cables provide the electrical performance and code compliance needed for large commercial and industrial deployments.
Available gauges include 18 AWG, 22 AWG, and 24 AWG (varies by item).
Available color options include: Black/White, Pair - Black/White, Single - Yellow, White-Blue/Blue, and White-Orange/Orange. Custom jacket and stripe color combinations can also be made to standardize your installations—contact Windy City Wire for details.
These cables use stranded copper conductors for flexibility and durability in Security & Access Control applications, with options in both tinned copper and bare copper depending on the item.
Windy City Wire manufactures and stocks this SmartWire® Security & Access Control cable in a standard 1,000 ft length. Additional lengths of 500 ft and 2,500 ft are also available on select items.
BAC NET™ refers to a building automation protocol; in this category it is commonly deployed as BACnet MS/TP over RS‑485 cabling, which uses shielded, low-capacitance twisted pair for longer runs and noise immunity. RS‑232 is a single‑ended, point‑to‑point serial interface for short distances that typically uses two conductors plus a ground. RS‑485 is a balanced, differential serial bus that supports multi‑drop networks over longer distances, typically using one twisted pair (often with an overall shield) and benefiting from low‑capacitance construction.
