Apparatus for enabling installation of recessed ceiling components

An apparatus for recessing ceiling components into ceiling drywall comprising:

• a recessed housing component containing a sensor module, said recessed housing being configured for installation into ceiling drywall substantially above said ceiling drywall,
• wherein said sensor module is configured to have multiple integrated sensors,
• wherein said integrated sensors further comprise:
• at least one smoke sensor;
• at least one carbon monoxide (“CO”) sensor;
• at least one humidity sensor;
• at least one temperature sensor;
• at least one particulate sensor;
• and
• at least one air quality sensor;
• said sensor module within said recessed housing having sensor electronics coupled with at least one sensor configured to determine if there is snoke within a smoke chamber and upon detection of said smoke causing a sound emitting element to initiate an audible sound;
• a sensor module enclosure containing said at least one sensor within said smoke chamber wherein said sensor module enclosure extends out of said recessed housing into a finish trim;
• and
• a finish trim element that couples with said recessed housing to cover said sensor enclosure;
• wherein said recessed housing is configured in a cylindrical tube shape having a circular side wall, a top end cap, and an open end which extends through said ceiling drywall;
• and
• wherein said recessed housing does not extend below said ceiling and said finish trim is flush with said ceiling.
