  • Protective electrical system for providing indications of removal of objects from plural monitored locations by use of parallel-connected object-sensors
    Patent number: 4268823
    Abstract: A photocell is placed beneath a packet of real or simulated currency at each of a plurality of teller locations in a bank. The photocells at the several teller locations are connected in a parallel circuit with each other, and a voltage supply source is connected to the parallel circuit through a common current-sensing resistance, so that if currency is removed from any teller location this will be indicated by a voltage drop across the common current-sensing resistance. The common current-sensing resistance is located in a control box at a remote location within the bank, and used to control even more remote alarm equipment, at a police station for example.
