NIGP 05579: Sirens, Horns and Back-Up Alarms

NIGP 05579 Sirens, Horns and Back-Up Alarms, an Item code, captures state and local government procurement of warning and emergency alert equipment, including inspection and maintenance services for installed siren systems. State and local buyers soliciting under this code are primarily counties and specialized public safety districts managing emergency warning infrastructure and fleet-mounted emergency equipment for law enforcement and public works operations. Kenosha County, Wisconsin issued an RFB on April 2, 2026 (due April 29, 2026) for inspection and maintenance services covering 35 warning sirens across an 18-month cycle through October 2031, with fixed unit pricing for four scheduled inspections and on-call repair services available at a 72-hour maximum response time. New Jersey's statewide law enforcement procurement (Bid Solicitation #26DPP01214, T0106, posted February 6, 2026, due March 26, 2026) included vehicle equipment and siren systems as one of ten product categories, with bidders required to submit firm fixed percentage discounts from manufacturer price lists and hourly rates for installation and repair services; the contract awards to all responsive bidders meeting requirements and extends to more than 2,800 cooperative purchasing participants through NJSTART.

Recent activity shows county-level issuing bodies dominating the code, with particular emphasis on municipal emergency management operations and fleet electrification. Wisconsin and New Jersey account for the most visible recent procurement activity, with Kenosha County's dedicated siren maintenance contract representing direct equipment ownership and Columbia County, Georgia's vehicle upfitting RFP (posted March 11 and 13, 2026, due April 9, 2026) indicating demand for emergency lighting and siren installation as part of broader fleet modernization. The Kenosha opportunity requires five years of prior siren inspection experience, three references, and fixed pricing across four inspections at 35 locations; pre-bid conference scheduled April 14, 2026. New Jersey's statewide solicitation offers SBE and DVOB set-aside preferences applied through mini-bid evaluation and covers multiple agencies statewide, suggesting broader geographic demand concentrated in the Mid-Atlantic and Upper Midwest regions where emergency warning infrastructure renewal cycles drive periodic reprocurement activity.
