There was also a mobile mounted version, at one time, called the M*12. Most of the EOWS line was discontinued in the mid to late 1990s and newer designs, like the Modulator and DSA, have replaced it. The EOWS is not in standard production, as of 2008.

In Hawaii, EOWS 612 sirens are mostly yellow. In the rest of America, EOWS Sirens can be found in various colors, including brown, black, gray, blue, and yellow.

The sirens in the '80s were painted in either Civil Defense yellow or dark gray, and early 90s models were painted light gray, and were almost white. Custom colors, including blue and green, were available, too.
