SECTION 1 – OVERVIEW
Flash Technology’s FTS 350i-2 is a LED-based, FAA L-864 flashing red beacon. Prewired with power and alarm
cables and equipped with an integrated controller, the unit is ready for operation on connection with a customer
supplied AC line. The FTS 350i-2 is also available with an optional ADLS compatible radar interface.
The beacon is designed for the safety lighting of wind turbines, towers, flare stacks, chimneys, offshore oil
platforms, petrochemical facilities and other obstructions to aerial navigation, as specified by the FAA, FCC, ICAO
and Transport Canada. It has been certified to be in compliance with the requirements of each of these
organizations.
(page 6), the FTS 350i-2 (hereafter referred to as the beacon) operates from a 100-240 VAC
50/60 Hz AC line. The integrated controller flashes the beacon at night and synchronizes with other Flash
Technology beacons via its incorporated GPS receiver/antenna.
28 high performance red LEDs provide the FAA required visible light output. Seven infrared (IR) LEDs ensure
visibility of the obstruction light to pilots flying with night vision aids (NVG/NVIS). The combination of red (620nm)
LEDs and IR (850nm) LEDs ensures maximum visibility to pilots in all circumstances while providing significant
electrical power savings over incandescent fixtures.
The lighting system is equipped with an alarm contact to monitor its operation. Beacon operation, GPS sync and
mode change function is monitored with alarms generated for any failure.
This manual provides guidance and recommendations for the installation, inspection and testing of the beacon
assembly. Please read this document in its entirety before installing the beacon.
