Description

The FTS 371 SMART is a low-power FAA L-810/L-864 red obstruction lighting system for FAA type A0/A1 structures. It meets changing FAA regulations for flashing markers.

 

With LED replacing incandescent lighting and marker power consumption decreasing by as much as 98%, a new approach for accurate monitoring is required. The FTS 371 uses a patent-pending current feedback monitoring technology that will not fluctuate with changes in incoming power and temperature, providing consistent and predictable results.

 

The FTS 371 SMART meets FAA AC 150/5345-43J and can accommodate both AC 70/7460-1K and 1L marker requirements. The system also meets Transport Canada CAR 621.19, ICAO Type B and Type C (7th Edition) and DGAC Mexico.
