According to one embodiment, a mounting plate for coupling a hazard detector with a wall or ceiling of a structure is provided. The mounting plate includes a plate that is positionable against the wall or ceiling to removably couple the hazard detector to the wall or ceiling. The mounting plate also includes a centrally located opening, a first set of apertures arranged around the centrally located opening, and a second set of apertures arranged around the centrally located opening. The first set of apertures are dimensioned and arranged according to a first attachment standard that defines a first distance range relative to an axis of the centrally located aperture and the second set of apertures are dimensioned and arranged according to a second attachment standard that defines a second distance range relative to the axis of the centrally located aperture.

Provided according to one or more embodiments is a thermostat having a housing, the housing including a forward-facing surface, the thermostat comprising a passive infrared (PIR) motion sensor disposed inside the housing for sensing occupancy in the vicinity of the thermostat. The PIR motion sensor has a radiation receiving surface and is able to detect the lateral movement of an occupant in front of the forward-facing surface of the housing. The thermostat further comprises a grille member having one or more openings and included along the forward-facing surface of the housing, the grille member being placed over the radiation receiving surface of the PIR motion sensor. The grille member is configured and dimensioned to visually conceal and protect the PIR motion sensor disposed inside the housing, the visual concealment promoting a visually pleasing quality of the thermostat, while at the same time permitting the PIR motion sensor to effectively detect the lateral movement of the occupant. In one embodiment, the grille member openings are slit-like openings oriented along a substantially horizontal direction.

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.

According to one embodiment, a hazard detector may include a housing having a back plate and a front casing coupled therewith to define an interior space within which various components are contained. The components may include an alarm device and a hazard sensor that is configured to detect a potentially hazardous condition to trigger the alarm device. A cover plate may be coupled with the housing and may face an occupant of a room in which the hazard detector is positioned. The cover plate may include a relatively large population of relatively small openings that are positioned, configured, and dimensioned so that internal components are substantially hidden from view of the occupant while air is allowed to substantially freely flow through the cover plate. A collective area of the openings may be at least 30% of the total area of the cover plate.
