Abstract
A fire assembly that can be used for installing recessed electrical fixtures into various structures such as wall assemblies is provided. The fire assembly includes an electrical fixture contained within a generally fire-resistant housing. The housing can enclose the electrical fixture in such a manner that the resulting fire assembly has an integral structure. In some instances, a support structure can be utilized to attach the housing to the electrical fixture. Furthermore, the housing can be a cube-shaped box have a variety of generally fire-resistant walls. These walls can be made from materials such as sheet rock.
Claims52
A wall assembly comprising a surface defining a wall of a building;
- and a fire assembly installed into an opening defined by said surface, said fire assembly comprising:
- a recessed fan assembly;
- and
- a housing substantially enclosing said recessed fan assembly such that said housing and said recessed fan assembly form a preassembled integral unit adapted installed behind a surface opening, said housing comprising at least one generally fire-resistant material, said housing enclosing said recessed fan assembly in a manner such that said housing is configured to form a continuous surface with said surface of said wall assembly.

A fire assembly adapted to be installed into a wall assembly, comprising:
- a recessed fan assembly;
- a housing substantially enclosing said recessed fan assembly such that said housing and said recessed fan assembly form a preassembled integral unit adapted for installation behind a surface opening defined by a surface of a wall assembly, said housing comprising at least one generally fire-resistant material, said housing enclosing said recessed fan assembly in a manner such that said housing is configured to form a continuous surface with said surface of said wall assembly;
- and
- a support structure, said support structure being connected to said housing and said fan assembly such that said housing, said fan assembly, and said support structure form said preassembled integral unit, said support structure defining an interior surface facing said fan assembly and an exterior surface, said housing only being located adjacent said exterior surface.
