Building owners and systems integrators are facing persistent obligations to maintain emergency radio coverage under model codes that govern public safety distributed antenna systems (DAS). Windy City Wire, a Bolingbrook, Illinois manufacturer and distributor of low-voltage wire and cable, is drawing attention to its support resources for integrators and contractors working on public safety DAS system projects, as Emergency Responder Communication Enhancement System (ERCES) requirements continue well past a building’s first approval.
Under the model codes that govern these systems, International Fire Code Section 510 establishes when an ERCES is required, while NFPA 1225 provides the technical design and testing guidance. Those requirements typically call for 95% radio coverage across required floor areas, 99% coverage in critical locations, and annual inspection and testing. IFC 510 also applies to existing buildings, which can be required to add ERCES if coverage testing fails. Enforcement is handled at the state and local level by Authorities Having Jurisdiction, so requirements can vary from one city to the next.
Windy City Wire offers SmartGUARD DAS cable solutions and full support services for DAS and ERCES deployments, along with fast-turnaround budgetary Rough Order of Magnitude (ROM) bills of materials. Its DAS resource center includes RF cable such as 50-ohm braided coax, along with plenum cables, SmartGuard cables, and a Dragonskin 2-hour offering, as well as a ROM bill of materials request form.
The company works with industry equipment manufacturers such as RFS, ADRF, Westell and GWave, and its DAS resource center references Westell iBwave design. Windy City Wire operates 19 stocking locations across the United States, where integrators can source first responder DAS wire and cable.
Integrators and contractors can request a ROM bill of materials or send a question to one of the company’s DAS experts through its DAS resource center at windycitywire.com/das, which also links to planning tools including a conduit fill calculator and a voltage drop calculator. The company’s customer service team is available at 1.800.379.1191, Monday through Friday from 7:00 a.m. to 7:00 p.m.
Windy City Wire manufactures and distributes low-voltage wire and cable solutions and has served the commercial integration industry since 1994. Headquartered in Bolingbrook, Illinois, the company supplies cable for security, access control, fire alarm, building automation, DAS and professional AV applications, and is known for its SmartWire product line and RackPack field systems. Windy City Wire operates 19 stocking locations across the United States and was named a 2026 PSA Network P3 Elite Partner.
For integrators and building owners, the announcement underscores that ERCES compliance is not a one-time event but an ongoing responsibility. With enforcement varying by jurisdiction and existing buildings subject to retrofits if coverage tests fail, access to reliable cable, design references and rapid budgetary estimates can help reduce project risk. Windy City Wire’s focus on first responder DAS wire and cable, combined with its national stocking footprint and manufacturer partnerships, positions it as a resource for teams navigating the technical and regulatory demands of public safety DAS deployments.
