    Abstract: Various embodiments of a smoke chamber for a smoke detector are presented. Such a smoke chamber may include a housing, having a first portion and a second portion. The first portion may be through which an electromagnetic sensor and two or more electromagnetic emitters interact with an airspace within the housing. The second portion may have an airflow surface that at least partially defines a curved airflow path between the airspace within the housing and an external environment. The curved airflow path may curve radially outward.

    Abstract: Various arrangements for using multiple wavelengths of electromagnetic radiation to detect smoke by a smoke detector are present. Multiple modes of the smoke detector may be used in which a first wavelength of electromagnetic radiation is emitted into a smoke chamber while a second electromagnetic radiation emitter is disabled, a period of time is waited, and a second wavelength of electromagnetic radiation is emitted into the smoke chamber while the first emitter is disabled. Depending on the mode of the smoke detector, the period of wait time may be varied.

    Abstract: This application is directed to a waterproof power adapter, which includes: a waterproof housing enclosing an AC to DC converter having an AC power supply input and a DC power supply output; a fixed, waterproof AC power connection for coupling an external power supply to the AC power supply input; a female connector, a portion of which is coupled within the housing to the DC power supply output, and an exposed portion of which is configured to couple a DC voltage provided at the DC power supply output to a complementary and separate male connector, the exposed portion being exposed when not coupled to the male connector; a sealing structure configured to engage with a cover of the male connector in a sealed position to provide a waterproof environment; and a locking mechanism configured to releasably tighten and lock the cover of the male connector in the sealed position.

    Abstract: A hazard detector includes a chassis configured to house components of the hazard detector. The chassis includes a front defining a central aperture. The front has a domed contour such that an outer edge of an inner portion extends beyond an outer periphery of the front. The inner surface tapers from the outer edge toward the inner portion. The detector includes a mesh formed to the contour of the front so the mesh is flat against the front. The mesh defines an aperture corresponding to the central aperture. The detector includes a grille secured to the chassis that defines an aperture corresponding to the central aperture and defines openings positioned along the grille. An inner surface of the grille includes a contour corresponding to the contour of the front so the mesh is flat against the inner surface. The mesh is positioned between the grille and the chassis.
