The Vanguard Medium FTS 370d is a dual FAA L-864/L-865 medium intensity LED lighting system for structures between 200’ and 700’ AGL (FAA E-type towers).

The system also meets FAA L-885 low intensity catenary requirements. It complies with CAR 621 2nd edition for medium intensity CL-864/CL-865 flashing lights and ICAO 6th edition standards for medium intensity type A/type B obstacle lights.

The FTS 370d uses a single cable for communications as well as beacon and marker power. Firmware can be upgraded for future compatibility with no need for controller modification. The single enclosure houses a low-voltage environment, removing the need for an interlock switch and allowing alarms to remain active when the door is open.
