UNSPSC 46191502: Heat detectors

UNSPSC 46191502 Heat detectors (Commodity) covers the procurement of heat-sensing fire detection devices by state and local governments, though recent opportunities show the code is being applied to a broader mix of fire detection, notification, and suppression infrastructure work. State and local buyers use this Commodity code for standalone heat detector units as well as for fire system projects that bundle heat detectors with smoke alarms, sprinkler systems, fire alarm control panels, and integrated notification appliances. The issuing bodies span county governments, cities, public utilities, state agencies, school districts, and special-purpose districts; no single repeat buyer dominates recent solicitations, but Florida and Texas jurisdictions appear frequently. Work being solicited includes purchase of specific detector models (such as First Alert/BRK battery-powered smoke alarms with ionization sensors ordered by Dallas City Hall), replacement of institutional sprinklers and fire alarm systems in correctional facilities (Collin County Jail replacement of Tyco Raven sprinklers, valued at $150,000), and comprehensive fire protection system inspection and maintenance contracts spanning multiple facilities (Hillsborough County Public Schools' RFP for inspection and repair of CO2 extinguisher and sprinkler systems across 235 schools).

Recent activity concentrates in Florida, Texas, California, Georgia, Connecticut, Mississippi, Illinois, and the District of Columbia. A representative sample includes Collin County, Texas issuing an IFB on October 15, 2026, for sprinkler head replacement at the county jail with a response deadline of November 19, 2026 (estimated construction cost $150,000); the City of Bridgeport, Connecticut posting an RFQ on October 7, 2026, for smoke alarms and combination smoke/carbon monoxide alarms with mandatory product specifications and a response deadline of October 28, 2026; Hillsborough County Public Schools issuing an RFP on September 7, 2026, for fire protection system inspection and repair services with a pre-proposal conference on September 8, 2026 and proposals due October 5, 2026; the City of St. Marys, Georgia posting an RFP on September 3, 2026, for security access control and fire alarm notification systems at a new city hall, with proposals due October 7, 2026; and the California Public Utilities Commission issuing an RFQ on May 20, 2026, for halon fire suppression system services with a maximum contract value of $239,600 across a two-year base term and three optional one-year extensions. The code shows consistent, diversified activity across municipal, county, and regional procurement offices, with work ranging from low-value commodity purchases (smoke alarm units) to six-figure system upgrades and multi-year maintenance contracts.
