1. A multi-sensing hazard detector for use in a building or structure for detecting potential dangers therein, the multi-sensing hazard detector comprising:

  • a back plate that is couplable with a wall or ceiling of the building or structure so as to secure the multi-sensing hazard detector relative thereto;

    a front casing coupled with the back plate to define a housing having an interior region within which a plurality of components of the multi-sensing hazard detector are at least partially contained, the housing having a plurality of openings through which air flows so that the air is accessible to the components within the interior region of the housing;

    a circuit board coupled with the housing and having the plurality of components communicatively coupled therewith, the plurality of components including;

    an alarm device communicatively coupled with the circuit board, the alarm device being activatable upon the detection of a potential hazard so as to warn an occupant of the building or structure of a potential danger;

    an occupancy sensor communicatively coupled with the circuit board, the occupancy sensor being configured to detect the presence and/or movement of objects and/or persons external to the multi-sensing hazard detector; and

    a smoke chamber communicatively coupled with the circuit board and configured to detect the presence of smoke and to trigger the alarm device upon the detection of smoke;

    wherein the housing of the multi-sensing hazard detector comprises a volume of less than about 1024 cubic centimeters; and

    wherein the multi-sensing hazard detector is relatively flat so as not to extend excessively outwardly from the wall or ceiling, the multi-sensing hazard detector having a minimum aspect ratio defined as a thickness dimension thereof extending outwardly from the wall or ceiling divided by a longest lateral dimension perpendicular to said thickness dimension, the multi-sensing hazard detector having a maximum aspect ratio defined as a thickness dimension thereof extending outwardly from the wall or ceiling divided by a shortest lateral dimension perpendicular to said thickness dimension, wherein each of said minimum aspect ratio and said maximum aspect ratio is less than about 33%.
