INTRODUCTION & OPERATION
SYSTEM OVERVIEW
The FTS 270 system is an LED Obstruction Lighting System monitored and controlled by the FTC 270 controller. The
FTS 270 system may be comprised of High Intensity LED obstruction lights (FH 270), Medium Intensity LED
obstruction lights (FH 372) and Low-Intensity LED obstruction lights (MKR 371). A complete system also includes
the power converters for the LED obstruction lights. The system lights can produce white, red and infrared light in
their appropriate modes.
The FTS 270 system is designed to meet and exceed FAA, ICAO and Transport Canada (TC) regulations and may be
utilized for their corresponding valid obstruction lighting configurations. The FTC 270 controller can monitor,
control and synchronize multiple High-intensity, Medium-intensity and Low-intensity lights.
The following table illustrates the systems capabilities:

Flash Technology engineered the FTS 270 LED Lighting System for maximum LED life, reducing the need for service.
Simple wiring, setup, and diagnostics increase the ease of installation and service.
Each high-intensity obstruction light consists of a flashhead (FH 270) and a connected power converter (PC 270). A
maximum of forty-eight high intensity lights may be connected in a single lighting system. The light source for the
flashhead is comprised of LEDs (Light Emitting Diodes). The LED control circuitry and drivers are located in the
power converter. RS-485 communication is utilized as the communication link between the PC 270 and the system
controller (FTC 270). The PC 270 may be located up to 2200’ (RS-485 cable length) from the controller.
The FTS 372 is used on installations requiring a medium-intensity AOL beacon. The FTS 372 system consists of an
LED flashhead (FH 372) and a connected power converter (PC 372). A maximum of nine (9) medium-intensity AOL
beacons can be connected in a single lighting system. The FH 372 communicates with the FTC 270 via RS-485
