UNSPSC 45111710: Chime and siren unit

A type of device that has the generation of 4 scales of chime for upward or downward level of soft sound color used to inform the beginning and ending of information broadcasting.

UNSPSC 45111710 Chime and siren unit (Commodity) names a specific product — alert-signaling devices — but the recent state and local opportunities tagged under this code involve comprehensive audio-visual systems integration, equipment refreshes, and production services across civic, educational, and cultural facilities, not chime or siren units. The code shows a significant mismatch between its nominal scope and actual procurement activity. Recent state and local solicitations under 45111710 have focused on city council chambers upgrades, courtroom A/V systems, emergency operations center audio-visual renovations, classroom multimedia systems, stadium sound reinforcement, and specialized production rigging services — all audio-visual infrastructure rather than alert devices. This divergence suggests either systematic misclassification by issuing bodies or that the code has drifted in practice from its intended commodity definition.

The issuing bodies pursuing work labeled under 45111710 span a broad jurisdictional range: cities (Holly Hill and Arlington, Texas; Tybee Island, Georgia; College Park, Georgia; Santa Monica, California), counties (Volusia, Gwinnett, Collin, Wake, Harris, Marion, and Monroe in Florida and Georgia), school districts (Fort Bend ISD, City Colleges of Chicago, Clarkston Community Schools, Dallas ISD, Northside ISD, Fulton County Schools), and special-purpose authorities (Georgia World Congress Center Authority, Auraria Higher Education Center, Railroad Commission of Texas, Texas A&M System). The geographic distribution spans Florida, Georgia, Texas, Michigan, Colorado, California, Illinois, and Ohio. Representative recent opportunities include the City of Holly Hill seeking Commission Chambers A/V upgrades (RFP 26PW01, sealed proposals due February 11, 2026), Volusia County requesting Emergency Operations Center A/V and IT renovations (RFP 26-P-33JRD, proposals due January 29, 2026), the City of Dahlonega soliciting City Hall Council Chambers A/V upgrades (RFP PE69315NONST2026, proposals due October 23, 2026), Fort Bend ISD requesting athletics audio-visual equipment and services (RFP 27011RA, proposals due November 16, 2026), and the Georgia World Congress Center Authority seeking comprehensive audio-visual and production rigging services (RFP PE92200RFP2027000000093, proposals due September 30, 2026). The code's recent activity is dense and geographically dispersed; however, the substantial mismatch between the commodity name and what is actually being bought undermines reliability of this category as a procurement signal.
