Our ATC Panels Services

From cabinet audits to commissioning and repairs, TCC supports safer, more reliable traffic signal operations.

Cabinet Audits

TCC performs detailed physical and electrical cabinet inspections, checking grounding, surge protection, load switches, flashers, power supplies, backpanel wiring, thermal management, UPS condition, and battery health to prevent avoidable outages.

Onsite Troubleshooting

When an intersection malfunctions, TCC technicians diagnose the controller, monitor, wiring, load switches, detection inputs, and communications systems to isolate the fault and recommend repair or replacement actions.

Signal Turn On

For new or rebuilt signalized intersections, TCC verifies cabinet wiring, phasing, conflict monitor programming, flash operation, and full signal function before the system is handed off to the agency.

Monitor Testing

TCC bench tests MMU and CMU units against NEMA fault-detection standards, providing documented certification for the conflict monitors that safeguard intersections from conflicting green indications.

Controller Repair

TCC diagnoses returned traffic signal controllers, replaces failed components or boards, reloads firmware, and tests each unit through a full operational cycle before returning it to service.

Product Guidance

TCC engineers help agencies and consultants match ATC panel equipment to intersection geometry, cabinet type, project specifications, legacy constraints, and compatibility requirements before procurement or bid release.
