ABSTRACT:
An electronic security system for monitoring merchandise and the like is provided which is responsive to any change of state in the electrical connections thereto thus providing for the detection of virtually any tampering with the merchandise or security system. Conductive loop sensors attached to the merchandise are releasably coupled to series-connected modular sensor monitoring units which in turn are connected to a single control box enclosing latching and alarm circuits. Each monitoring unit is preferably adapted to receive a plurality of conductive loops. Severing of any of the loops, as well as disconnection or reconnection of the loops, the monitoring units or the control box activates the alarm. A time-out circuit controls the length of time of alarm activation and is switchable between long and short alarm durations.
Means facilitating the mounting of the manifold units and control box on existing T-stand and wall rack clothing displays, are also disclosed.
