The EOWS series (Electronic Outdoor Warning Siren) was a line of electronic sirens produced by Federal Signal Corporation.

There were a total of 6 mainstream models in the series:

Model	Output	Drivers	Notes
EOWS*115	119 dBc	12 (1 per horn)	The earliest model in the series. Uncommon. Sound output is likely inaccurate regardless of documented rating. Output is likely 115 dBc.
EOWS*408	128 dBc	8 (2 per horn)	The smallest rotating siren in the series. Quite rare. Sound output rating is inaccurate in documentation. Actual output rating is unknown.
EOWS*612	124 dBc	12 (2 per horn)	The most popular model. Many active examples can still be found today.
EOWS*812	132 dBc	12 (2 per horn for bottom 4 horns, and 1 per horn for top 4 horns)	The largest siren in the series. Rather uncommon. Sound output is likely inaccurate regardless of documented rating. Actual output rating is likely 124dBc.
EOWS*1212	115 dBc	12 (1 per horn)	The successor to the 115.
EOWS*M12	123 dBc	?	Vehicular model. Decibel rating was measured at ten feet.

The EOWS*115 was the earliest model produced. It is unique in the series in that it uses fiberglass re-entrant horns.
