Federal Signal's Model 121X rotating light flashes 90 times per minute and produces a 360º visual signal. This explosion-proof light has an incandescent lamp and is available in five lens colors - amber, blue, clear, green and red.
The Model 121X is UL Listed for Class I, Division 1, Groups C & D; Class II, Division 1, Groups E, F & G; Class I, Division 2, Groups A, B; and Class III. The 121X is CSA Certified, Marine Rated and contructed to Type 4X, IP66 standards.
This corrosion-resistant unit's copper-free aluminum housing is finished with a powder epoxy. All exposed hardware is constructed of 316 grade stainless steel.
The 121X uses a synchronous motor to drive a parabolic reflector around an incandescent lamp. This results in a 360º rotating beam which is concentrated in a horizontal plane.
The 121X features a spring-clip mounted lens for quick access when inspecting or relamping. A pendant mount is supplied, and a ceiling mount and 90º wall mount are available options. Installation is simple; with the mounting box in place, the fixture is threaded onto the mounting box, making the electrical connection. Electrical continuity is made when five threads are engaged.
Federal Signal's rugged 121X Warning Light is designed for explosion-proof applications and/or corrosive environments. It is ideal for use in indoor and outdoor areas such as oil rigs, mines, refineries, and chemical plants.
