The Model ECLIPSE refers to two mid-range DC-powered mechanical sirens manufactured by Federal Signal Corporation, the Model ECLIPSE8 and Model ECLIPSENH.
The Model ECLIPSE8 and Model ECLIPSENH compete with similar sirens such as ASC's T-121 and Sentry Siren's 3V8-B and 7V8-B. However, they are greatly outperformed by the ASC T-121.
Models
Model ECLIPSE8
Introduced into Federal's lineup in 2006, the Model ECLIPSE8 is powered by a small 7 hp DC motor, driving an 8-port rotor and stator. The Model ECLIPSE8 is a very simple siren, and is made of unpainted, corrosion-resistant stainless steel which greatly improves its durability and resistance to weathering. Because of this, the Model ECLIPSE8 is suited to nearly any environment.
Being a DC powered siren, the Model ECLIPSE8 is battery backup capable, and can also be run on solar panels. If DC power is unavailable, the siren can also run on an AC rectifier. The Model ECLIPSE8 is meant as a small siren for small towns or coverage gaps where battery backup is wanted and boasts a performance of 115 dB at 100 ft, equivalent to its predecessor, the larger STH-10. It has become popular with fire stations as a replacement for aging Federal Signal Model 5s, none of which can run when the power is out. The Model ECLIPSE8 directly replaced Federal's STH-10 in Federal's lineup, as it is a superior siren for its purpose.
The Model ECLIPSE8 also has a rotational variant in the form of the Equinox, which is a 2001-130 with the Model ECLIPSE8's rotor and stator replacing the usual 12-port Model 5 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 508-128 rotational siren, which was an improved design over the Equinox.
Model ECLIPSENH
The Model ECLIPSE8 has a variant without the horns attached, which is known as the Model ECLIPSENH. It is considered an even cheaper option for towns on a budget and as a competitor to the T-112, but this severely harms the siren's sound output and range as it can only reach 107 dB at 100 ft. The Model ECLIPSENH has the horn mounts visible on the stator ports, similar to the T-112. The Model ECLIPSENH is very rare, due to its severely lacking performance and disadvantages compared to the Model ECLIPSE8 and T-112, making it obsolete even in its own niche.
