Medium Intensity Led Lighting System (Fts 372 Aol) - Flash Technology VANGUARD FTS 270 Reference Manual

MEDIUM INTENSITY LED LIGHTING SYS TEM (FTS 372 AOL)
The FTS 372 is a medium intensity obstruction (L865/L864) lighting system. The FTS 372 is a dual (white and red)
LED light which includes Infrared LEDs. The FTS 372 is used for applications that require the use of an "AOL
Flashhead" (i.e. F-Style and C-Style towers).
The FTS 372 is composed of a flashhead (FH 372) and a power converter (PC 372). The power converter may be
installed at the same elevation as the top tier of L-856 lights (up to 2,000 ft. above ground level). It accepts an
input power of 100-277 VAC 50/60 Hz. The power converter provides the operating voltage for the FH 372 (~58
VDC), and is a pass-thru for the RS-485 communications. The FH 372 may be installed up to 375ft. from the power
converter with #10 conductors.
PC 372 - TB1 INPUT POWER AND TOWER COMMUNICATIONS CONNECTION POINT
Input power is connected to terminal block TB1. Mounted on TB1 are surge suppression modules, which reduce AC
power line surges and transient voltages. Input power circuit breakers are also mounted on TB1. Disconnect power
from TB1 before servicing circuit breakers or OVPs.
Flag indicator on the 2-pole circuit breakers is clearly marked with green OFF and red ON.
The PC 372 will have two RS-485 connections on TB1 (input and output). The RS-485 connections only to serve as
a pass-through for the RS-485 connection to the FH 372. Nothing inside the PC 372 communicates on the RS-485
lines.
