Detector unit with multiple integrated sensing systems and visually pleasing housing

摘要

According to one embodiment, a multi-sensing hazard detector for detecting potential dangers may include a back plate and a front casing that is coupled with the back plate to define a housing. A circuit board and a plurality of components may be positioned within the housing. The circuit board may be communicatively coupled with the components. The components may include, among other components, an alarm device, an occupancy sensor, and a smoke chamber. The alarm device may be activatable upon the detection of a potential hazard to warn an occupant of a potential danger, the occupancy sensor may be configured to detect the presence and/or movement of objects external to the hazard detector, and the smoke chamber may be configured to detect the presence of smoke to cause a triggering of the alarm device. The housing may comprise a volume of less than 1024 cubic centimeters.

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; anda 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%.
