Surge Protection Device (SPD) Supply and Integration

The contract requires the supply and integration of UL1449-compliant surge protection devices designed for installation within traffic signal controller cabinets, each rated to handle a peak surge current of 20,000 amps. These devices must include built-in failure indicators and remote alarm contacts configured as both normally open and normally closed to enable seamless integration with existing monitoring systems for real-time operational awareness. The work is scoped as a subcontract under the Texas Department of Transportation, with performance expected across the state’s traffic signal infrastructure. All components must meet strict industry standards for surge protection and reliability to ensure uninterrupted signal operation under extreme electrical conditions. The solicitation was posted on August 5, 2026, with responses due by August 19, 2026, and is classified under NAICS code 335313, indicating the focus on electrical equipment manufacturing. The place of performance and agency office details are not specified, suggesting the work may be distributed statewide or coordinated through centralized logistics. Contractors must ensure full compliance with UL1449 requirements, proper integration into existing cabinet infrastructure, and delivery of functional alarm contacts that enable remote diagnostics without requiring physical inspection. Subcontractors are expected to provide documentation, testing verification, and support to confirm system-wide compatibility and reliability under operational conditions.
