  • Patent number: 8797724
    Abstract: A notification appliance enclosure that facilitates convenient attachment and removal of a housing. The enclosure may include a mounting plate having a catch lip and a retaining wedge projecting from a surface thereof. The catch lip and the retaining wedge may be spaced apart to define a retaining pocket therebetween, and the catch lip may have a latch release aperture formed therethrough. A housing may fit over the mounting plate and may have a latch tongue extending from a surface thereof fits within the retaining pocket. A release latch may extend from a surface of latch tongue and may fit within the latch release aperture. The engagement between the release latch and the latch release aperture prevents the housing from being pulled away from the mounting plate. The retaining wedge resists movement of the latch tongue and thereby resists disengagement of the release latch from the latch release aperture.
