The ECLIPSE is a mid-range, DC-powered mechanical omni-directional siren manufactured by Federal Signal Corporation.
History and Design
The ECLIPSE was introduced to market in August of 2005, succeeding the popular STH-10 siren which was discontinued in December of the same year. The ECLIPSE was created due to the increasing demand for a DC-powered omnidirectional siren, which Federal lacked at the time. Federal opted to use a rotor design very similar to those used in ASC's Tempest sirens, which resulted in a high-performance siren that did not consume much power. 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 steel STH-10. The ECLIPSE is powered by the same 6.5 hp 48 V DC motor found in the 2001 line. Coupled with an 8-port rotor, the Eclipse is capable of producing a 500 Hz tone up to 115 dBc at 100 ft[1]. The ECLIPSE is designed to operate with any power requirements, whether 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.
ECLIPSE8
ECLIPSE8 is the main model, equipped with projector horns for the maximum performance the Eclipse has to offer, up to 115 dBc at 100 ft[1]. It is the most common of the 2 models. The Model ECLIPSE8 also shares traits with the Equinox, simply a 2001-130 with the Model ECLIPSE8's rotor and stator replacing the usual 12-port rotor and stator. Unfortunately, the Model ECLIPSE8's chopper is not suited for this purpose, sticking out into the Equinox's housing, hampering air intake and resulting in severely reduced sound output. The Model ECLIPSE8's rotor and stator also are used in the Model 508-128, an improved design over the Equinox.
ECLIPSENH
ECLIPSENH (NH standing for No Horns) is a variant of the ECLIPSE8 which 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 ft. Due to its lack of performance and advertising, it is far less common than the ECLIPSE8.
