ABSTRACT:
A smoke-detector security cover has a toroidal base plate attachable to a wall or ceiling surrounding a smoke detector. A toroidal cover plate having a plurality of retainer appendages extended inward radially is connected to the toroidal base plate to cover portions of the smoke detector circumferentially external from a central smoke-detection section of the smoke detector. Attachment rods are extended perpendicularly from the base plate towards the cover plate. Attachment sleeves are extended perpendicularly from the cover plate in sliding contact with the attachment rods telescopically. An anti-theft fastener means is provided in fastener relationship between at least one attachment rod and one attachment sleeve. The anti-theft fastener means can be a split attachment bolt that is tightened in an attachment sleeve with a tapered fastener head or tapered fastener shank. The fastener has an anti-theft head. The anti-theft head can be recessed to further deter unauthorized removal. The anti-theft fastener head can be one that requires a key wrench such as a pin wrench or an off-shaped wrench boss to fit into corresponding pin-wrench holes or an off-shaped wrench socket in order to rotate the fastener head. Optionally, the anti-theft fastener means can be or can include a conventional tumbler lock positioned in locking relationship between an attachment rod and an attachment sleeve to require a key or a combination to disengage.
