COVER PLATE FOR A HAZARD DETECTOR HAVING IMPROVED AIR FLOW AND OTHER CHARACTERISTICS

摘要

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.

主权项

1. A hazard detector for use in a building or structure for detecting a hazard, the hazard detector comprising:
a back plate couplable with a wall or ceiling of the building or structure; a front casing coupled with the back plate; a circuit board positioned within an interior of the hazard detector; a hazard sensor electrically coupled with the circuit board, the hazard sensor having one or more components configured to detect a potentially hazardous condition; an alarm device electrically coupled with the circuit board, the alarm device being activatable upon detection of a hazard; one or more sensors electrically coupled with the circuit board, the one or more sensors being configured to detect a presence and/or movement of objects and/or persons external to the hazard detector; and a cover plate coupled with the front casing so as to face an occupant of a room or area in which the hazard detector is positioned, the cover plate including a relatively large population of relatively small openings that are dimensioned so (A) internal components are substantially hidden from view of the occupant, (B) air is allowed to flow through the cover plate to the hazard sensor, and (C) the one or more sensors are capable of detecting the objects and/or persons from behind the cover plate, wherein a collective area of the small openings is at least 30% of the cover plate.
