The AtlasIED FC104T72FRK is a pre-manufactured fire-rated ceiling speaker package designed for installed audio systems where code compliance and efficient installation matter. It combines the speaker/transformer assembly, baffle, and fiber enclosure kit into a coordinated solution intended for use in UL-classified fire-resistance ceiling constructions. This makes it a practical choice for projects that require a tested assembly rather than piecing together separate parts in the field.

Built around a 4" high-compliance loudspeaker with a 4-watt 70-volt transformer, the FC104T72FRK is suited to public address and background music applications. Its wide-range response and wide-angle coverage support clear announcements and distributed audio in commercial spaces. The kit is designed for quick on-site assembly using the included pre-cut fiber panels, metal enclosure, rail set, and hardware, helping streamline installation on jobs with fire-rated ceiling requirements.
