Various arrangements of smart devices are presented. Such a smart device may include a case, a wireless interface, a light sensor that detects an ambient brightness level of an ambient environment of the smart device, a motion sensor that detects motion of a user in the ambient environment of the smart device, a light that is capable of outputting light into the ambient environment of the smart device, and a processing system. The processing system may cause the light to illuminate based on: the message indicating that the lighting feature has been activated; the ambient brightness level being below the threshold brightness value; and the user moving in the ambient environment of the smart device.

According to one embodiment, a displacement control member may be operationally coupled with a selectable button of a hazard detector so that axial depression of the selectable button effects pivoting of the selectable button and the displacement control member into contact with a switch of the hazard detector. The displacement control member may be coupled with the selectable button so that a ratio of a distance from the switch to a point of user contact with the selectable button and a distance from the switch to a pivot point of the displacement control member is similar regardless of where the user contacts the selectable button. The displacement control member may equalize a user input force that is required to activate the hazard detector's switch.

Various embodiments of hazard detectors are presented. A hazard sensor may be present that detects the presence of a hazardous condition. A light sensor may be present that detects an ambient brightness level. A motion sensor may be present that detects motion of a user. A light may be present that is capable of outputting light. A processing system may receive an indication of the ambient brightness level in the ambient environment of the hazard detector from the light sensor. The processing system may determine that the ambient brightness level is less than a threshold brightness. The processing system may receive information indicative of the user moving in the ambient environment of the hazard detector. The processing system may cause the light to illuminate based on the ambient brightness level being below the threshold brightness and the user moving in the ambient environment of the hazard detector.

According to one embodiment, an access door for a hazard detector includes a release member that releasably secures the access door in a closed position over a battery compartment of the hazard detector. The release member allows the access door to be pivoted open and closed relative to the battery compartment and hazard detector. The access door also includes a first hinge member and a second hinge member. The first hinge member enables the access door to pivot along a first pivot path and by a first pivot amount and the second hinge member enables the access door to pivot along a second pivot path and by a second pivot amount. A cumulative total of the first pivot amount and the second pivot amount is substantially greater than either pivot amount alone.

According to one embodiment, a casing of a hazard detector includes a body portion and a button portion. The button portion is coupled with the body portion via a plurality of arms. The arms allow the button portion to be axially movable relative to the body portion and also couple the button portion with the body portion so that tabs that extend radially outward from the button portion are positioned under and contact an inwardly facing surface of the body portion. The arms bias the button portion axially outward relative to the body portion so as maintain contact between the tabs and the inwardly facing surface. In this configuration, when the button portion is pressed at a position off-axis from a central axis of the button portion, the button portion pivots about one or more contact points between one or more tabs and the inwardly facing surface.

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.

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.

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.
