Abstract
Apparatus that includes alarms with indicators to prevent burglary and theft includes a depository (10) operative to receive deposit containers (20) from authorized persons who open a lock (24). The apparatus includes a depository head (12) and a chest (14). A security curtain assembly (36) comprising a plurality of movable plate members is operative to selectively block an opening in the top of the chest that communicates with the head in response to an actuator. The actuator operates responsive to at least one circuit to cause the security curtain to close responsive to sensing conditions that may correspond to an attack through one or more sensors. Alarms are given locally or remotely when the at least one circuit senses conditions that may correspond to an attack.
