Vanguard® Medium FTS 370d LED Tower Lighting System

Dual L-864 / L-865 Obstruction Lighting System

Designed for ease of installation, the Vanguard Medium FTS 370d LED tower lighting system is a dual (red and white) FAA L-864/L-865 or catenary (L-866/L-885) medium intensity LED aviation obstruction lighting system. It is suitable for structures between 200′ and 700′ AGL (FAA E-type towers). Efficiencies are engineered throughout the system, such as a single flashhead and marker cable for power and communication as well as a single enclosure for power, control and monitoring.

 

Vanguard Medium offers numerous monitoring and control options and is one of the most versatile lighting systems on the market.

Lightning Protection

The Vanguard Medium product line protects against 99% of lightning strikes, including the most intense strikes. It has a surge suppression rating of 25kA, validated by multiple lightning test laboratories. A properly grounded tower should take 55% of the lightning energy through the steel tower and to the ground, leaving 45% to be distributed amongst the cables. An average lightning strike is 28kA, with a 200kA strike happening less than 1% of the time. A 200kA strike on a tower using an average of 4 cables will deliver 22.5kA to the flashhead cable, much less than the FTS 370d’s 25kA rating.

 

Data Connectivity

Choose from many options to customize monitoring to your needs, whether performed by your NOC or by Flash Technology. Connectivity options include AT&T and Verizon LTE with supplied monitoring devices as well as an ethernet port. Modbus and SNMP protocols support third-party monitoring.

 

Easier Installation

Flash Technology’s LED L-810 marker is an integral part of the FTS 370d solution. At less than a pound in weight and requiring only two adjustable straps to mount, it’s the easiest marker to install on the market.

 

Made of powder-coated, lightweight aluminum, the versatile enclosure makes installation easier and reduces operating temperatures. Two lockable twist knobs provide easy access. A water channel diverts water away from the door opening. And knock-out holes in the bottom of the enclosure simplify cable installation.
