Additional Information


ELTEC’s FS-4 DC flasher for solar powered traffic warning systems combines the functionality of both the FS-3 and a timer.  It uses solid state circuitry and an integrated microprocessor for multiple programming options with minimal power consumption. Flash time is set by two rotary switches for flash time up to 99 seconds after activation. It can be used where there is a ready source of 11.4VDC-30VDC, but can also be integrated into AC systems (power supply added.)

The FS-4 is interchangeable; the dimensions are the same as the FS-3, FS-2A and FS-2B.  When programming the flash pattern for a Rectangular Rapid Flashing Beacon (RRFB) pedestrian crossing, FHWA approved Wig-Wag plus Simultaneous (WW+S) flash pattern are offered.
