*(FS155 & FA155 models only)
Description
FA155
The FA/FS Series have proven their reliability through years of
use on communication towers, smoke stacks, cooling towers,
tall buildings, bridges and utility towers. The highest quality
components are encapsulated in a rugged plastic housing with
a molded-in heat transfer plate. The flash rate, ratio, and fail-
safe design meet FAA regulations. Zero voltage switching can
increase lamp life up to ten times. The FS155-30RF includes
superior RF filtering circuitry for use in high RF installations,
including AM hot towers.

Operation
FS Series - Flasher (OFF First)
FA Series - Auxiliary Modules
Upon application of input voltage, theT2 OFF time begins. At
the end of the OFF time, theT1 ON time begins and the load
energizes. At the end ofT1, T2 begins and the load de-energizes.
This cycle repeats until voltage is removed.
