Section 1 — FTB 312-3 Introduction and Operation
System
The ElectroFlash
™
FTB 312-3 and FTS 316-2 or
FTS 316-3 Systems are dual (white/red) flashing,
medium intensity, obstruction lighting systems
designed and manufactured by Flash Technology
Corporation of America
®
(FTCA) for installations
that require white L-865 lights during the day
and L-864 red lights and markers at night.
A system consists of a power converter, a dual
flashhead or red and white flashheads, photocell,
and a cable between the flashhead and power con-
verter. Table 1-1 provides an overview of system
features.
The power converter provides discharge energy to
the flashhead, and contains components and cir-
cuitry to control flashing. The power converter
operates a white light at 40 flashes per minute
during the day. At night, it switches to a red light
at 20 flashes per minute, and turns on steadily-lit
markers. It is usually installed near ground level.
The FH 306 Flashhead is a dual (white/red) flash-
head; it has an internal red filter. An actuator
raises the filter to operate the flashhead in red
mode and lowers the filter to operate it in white
mode. Together, the lens and base enclose the
flashtube and other interior components. Latches
secure the lens, which tilts open for internal
access. Position the flashhead to comply with FAA
regulations in Advisory Circular 70/7460-1J,
Obstruction Lighting and Marking.
A flashhead cable interconnects the power con-
verter and flashhead. When FTCA Part Number
6340, or equivalent cable, is used, the two may be
separated by up to 600 feet (180 meters). Consult
the factory when a greater separation is neces-
sary.
The photocell is connected directly to the main
panel of the power converter at TB1-1 and TB1-2
to control switching between day and night opera-
tion. It may be located any practical distance from
the power converter.
FTS 316 Systems
An FTS 316 System combines an FTB 312-3 Sys-
tem with a 24VDC battery and DC-to-AC inverter
for continued operation if the main power fails.
The FTS 316-2 System consists of an FTB 312-3
System and an FIV 1100 Inverter.
The FTS 316-3 System consists of an FTB 312-3
System and an FIV 2000 Inverter.
