UNSPSC 32151501: Control sound module

UNSPSC 32151501 Control sound module is a Commodity code that captures state and local procurement of audio control and monitoring equipment integrated into supervisory control systems for industrial and infrastructure operations. Recent solicitations show this code applied primarily to SCADA (Supervisory Control and Data Acquisition) modernization projects at municipal water treatment plants, where control sound modules function as component parts of comprehensive system upgrades. The City of Atlanta's Hemphill Water Treatment Plant and Chattahoochee Water Treatment Plant SCADA improvements (both posted May 8, 2026, with May 29 response deadlines) exemplify the typical scope: replacement of obsolete control architectures with modern HMI systems, PLC upgrades, network modernization, and operator interface terminals that incorporate audio alerting and monitoring capabilities. Beyond water treatment, the code appears in classroom and conference room technology services (Valencia College District RFP 2026-26, April 30, 2026 deadline) and SCADA PLC replacement projects (City of Santa Fe Buckman Direct Diversion RFP FY26-RFP-036, December 18, 2025 deadline), where audio components support notification and system status communication. Issuing bodies are primarily municipal water authorities and public education systems, with one fire district (San Bernardino County Fire Protection District, February 20, 2026 notice) soliciting unrelated robotic equipment. Set-asides and disadvantaged-enterprise designations are not uniformly applied across these opportunities; the City of Santa Fe offers local preference (3–6% evaluation points), Jacksonville Transportation Authority establishes a 27% DBE goal, and San Bernardino County applies a 5% local vendor preference, while Atlanta and Valencia solicitations do not specify restrictions.

Activity concentrates in Georgia (City of Atlanta dual water treatment plant modernizations) and Florida (Valencia College, Jacksonville Transportation Authority, and City of Santa Fe procurement), with secondary representation in California (EMWD VFD procurement) and New Mexico (Santa Fe). The Atlanta water treatment opportunities are the most concrete recent examples: both require bidders to demonstrate five years of comparable integration experience, three prior water-treatment SCADA upgrades, and dedicated SCADA-experienced project managers and controls engineers; response deadlines have passed (May 29, 2026) but indicate typical qualification bars and integration-labor intensity. Valencia's three-year classroom technology contract (averaging $1.6 million annually over the prior five years) and Santa Fe's PLC replacement project (best-value evaluation with 35% weight on expertise and 30% on cost) suggest that control sound modules appear as bundled components in larger systems integration or equipment-supply contracts rather than as standalone procurements, making pursuit dependent on broader SCADA or infrastructure modernization opportunities in your target jurisdictions.
