Description

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 failsafe

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, the T2 OFF time begins. At

the end of the OFF time, the T1 ON time begins and the load

energizes. At the end of T1, T2 begins and the load de-energizes.

This cycle repeats until voltage is removed.

Reset: Removing input voltage resets the output and the

sequence to T2.
