ABSTRACT:
An alarm system and assembly including one or more base elements specifically structured for positioning on the interior of a jewelery-type display case and including a circuit means having an extended conductor interconnected in series with an alarm assembly and power source and further interconnected with a plurality of tray elements mounted on an exposed display platform to the extent that movement or actual removal of any of the tray elements will cause a break in the circuitry through separation of first and second contact pairs associated with the conductor means which in turn causes an activation of the signal assembly so as to provide a warning to attendant or merchants in the vicinity of the display case. Further, the signal assembly will be activated upon relative movement and/or displacement of the plurality of base elements independent of any displacement of tray elements.
