ABSTRACT:
Ceiling panel assemblies are conventionally suspended from a building structure, and each panel assembly has a core panel provided with dividers and spacers, and panel bridging members to allow cables to be strong in the ceiling as required to accommodate the power and low voltage requirements in the space therebelow. A decorative panel completes each panel assembly. A fire retardant panel may be provided also, to enclose the cables in wireways.
