UNSPSC 43221528 Supervisory signal unit (Commodity) addresses equipment and services that support remote emergency communications and network oversight across state and local public safety and emergency management infrastructure. Recent state and local solicitations show procurement of satellite-based communications terminals, emergency alert system hardware, telecommunications cabling and wiring infrastructure, public address system equipment, and associated installation and maintenance services. Issuing bodies span state emergency management agencies, county and municipal governments, school districts, transit and airport authorities, and state health and human services departments. Texas entities (state and local) appear prominently in recent activity, with additional solicitations from Washington, Florida, Michigan, Georgia, Illinois, and Virginia.

The Washington Military Department's October 2026 RFP seeks approximately 128 Low Earth Orbit satellite internet terminals (ranging from low-bandwidth pole-mounted units to higher-bandwidth mobile and fixed-site equipment) with 24/7 support and 99.9% uptime SLAs across Washington counties, responses due December 3, 2026, with MWBE goals of 10% and 6% and procurement preferences favoring Washington small businesses, veteran-owned businesses, and firms without mandatory arbitration clauses. The Texas Department of Information Resources' August 2026 cooperative purchasing RFP (COOP2026SOL-00008) targets cabling services and products across data, video, and voice systems for state agencies and local governments statewide, with historical annual volumes of $11.1 million to $12.0 million and mandatory accessibility documentation and VetHUB subcontracting plans. Northside Independent School District (San Antonio, Texas) solicited MAC telecommunications cabling services in September 2026 under RFP 2026079, replacing an expiring contract and requiring all incumbents to respond or forfeit renewal opportunities. The Illinois Department of Innovation and Technology issued an IFB in July 2026 for statewide non-VOIP telephone system maintenance across approximately 1,100 state locations, structured on time-and-materials regional hourly rates with indefinite-quantity and 10-year maximum term provisions.
