Abstract
Official abstract text for this publication.
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.
First claim
