Clear polycarbonate enclosure with backplate, siren alarm and key lock helps protect remote annunciators, fire alarm control panels and other electronic products against vandalism and damage as well as dirt, dust and grime. The cover mounts on the wall enabling the unit to be stored in a central location while allowing the device to be highly visible and accessible. When cabinet with siren alarm is opened, the alarm emits an ear piercing siren (model with siren/strobe alarm also flashes), drawing immediate attention to the area. Operator has to unlock the unit and open the lid for access.
