The Equinox is a rotating electromechanical siren produced by Federal Signal Corporation. It was initially a special order in 2011, essentially being a 2001-130 with an Eclipse-8 rotor. The intake and projector design of the 2001 proved to hamper it's full potential in testing, bottlenecking it's ability to move air and sound effectively. This led to a new development to fix said issues known today as the 508, with an improved overall intake/projector design to increase efficiency. The Equinox can be difficult to visibly differentiate from the 2001-130 as they look nearly identical, besides the "EQUINOX" sticker replacing "2001-130" on the rotator box. However, if you look closely, the stators are noticeably different on the 2 models. The 2001-130 has 12 individual projectors on the stator with narrow gaps between them, where the Equinox only has 8 with rather large gaps between them. In 2014, the Equinox was publicly introduced as a low tone option to the 2001 series and is still available today.
