    摘要: A box for covering components or the like and for preventing unwanted access thereto. The box comprises a mounting panel having a pair of opposed sides, a top portion, a bottom portion and a back portion. The back portion is adapted to receive a fastener for mounting the mounting panel to a mounting surface. A cover fastener is received within the mounting panel. A slot is formed in the mounting panel and a corresponding tang is located within the cover which is adapted to receive an alarm device therein and removably envelop the mounting panel. A second opening is located in the cover for receiving the cover fastener when said mounting panel is enveloped within the cover. The slot and the tang selectively movably cooperate with each other to enable the cover to initially envelop the mounting panel and subsequently secure the cover to the mounting panel as the cover fastener draws the cover toward the mounting panel, preventing the cover from being removed from the mounting panel without removal of the cover fastener. A circuit board is mounted within one of the mounting panel and the cover and is biased toward an ARMED position. The circuit board and the cover fastener cooperate to detect unauthorized tampering or attempts to remove the cover from the wall. When such activity is detected, an alarm electrically connected to the circuit board is activated.
