Federal Signal 2001-DC [Remastered] 8 RPM

The 2001 series is a warning siren intended as a successor to the Thunderbolt series. The 2001 is a common siren, being used in many cities and towns today.

The 2001 was first introduced as the 2001-DC Roundback, produced from 1988-1990. It used the same rotator assembly as the Thunderbolt. It earned the "Roundback" nickname due to its distinctive chopper housing 1990-1995. These models used the same rotators as the Thunderbolt, but with a different motor. The main difference is that the chopper housing is square-shaped.

The 2001-SRN, produced from 1998-2002, is one of the more common models in service today. It has a small Federal Signal on the center cone and a larger horn. The rotator assembly is shared with the Thunderbolt, this being the last model to use that rotator

Next comes the 2001-SRNB, made through 2003-2006. This was the first of the 2001 series to use a rotator not shared with the Thunderbolt. It used a gear-driven system, unlike the older belt-driven units. Otherwise, it is largely identical to the 2001-SRN. Most of the 2001-SRNB's have the big Federal Signal logo on its nose.
