By contrast, the ILS-3400 is a dual white/red system which produces 1 medium intensity
white flash every 1.5 seconds (40 FPM) in Day Mode to the lower of the two tubes and a
low intensity red “burst” of rapid flashes every 3 seconds (20 FPM) in Night Mode to the
upper of the two tubes. See major component block diagram below.
The intensity for all lighting systems is 20,000cd for a day flash and 2,000cd for a burst of
night flashes.
