The Eclipse is a mid-range, DC-powered mechanical omni-directional siren manufactured by Federal Signal Corporation.
The Eclipse was introduced to market in August of 2005, succeeding the popular STH-10 siren discontinued in December of the same year. The Eclipse features an aluminum construction consisting of a spun aluminum motor cover and intake as well as a cast aluminum stator, rotor and projector horns for excellent corrosion resistance, outclassing the rust-prone STH-10. The Eclipse is powered by the same 6.5 horsepower 48 Volt DC motor found in the 2001 siren series. Coupled with an 8-port rotor, the Eclipse is capable of producing a 500 Hertz tone up to 115 dBc at 100 feet[1]. These units are designed to operate with any power requirements, whether it's completely off grid with solar power, or fully grid-dependent through use of an AC to DC rectifier. They may be configured for pole or roof mounting, making them versatile for nearly any environment.
Models
Eclipse 8
Eclipse 8 is the main model, equipped with projector horns for the maximum performance the Eclipse has to offer, up to 115 dBc at 100 feet[1].
Eclipse NH
Eclipse NH, standing for No Horns, is the same as the Eclipse 8, but lacks projector horns for a cheaper, yet less performant model. This model was removed from public catalogs in 2013, becoming a special order item only. This model is capable of producing up to 107 dBc at 100 feet.
