Abstract
An anti-intrusion device simulates the sound of a round being chambered in a pump shotgun using metal parts which strike one another. A striker carriage is movably disposed in a sound box for moving between first and second positions to engage metal striker plates and metal striker tabs against sound plates to simulate the chambering sound. A mangle drive assembly is mounted atop the sound box for moving the striker carriage between a forward position and a rearward position, powered by a stepper motor which is actuated to rotate a controlled axial displacement when a trigger mechanism is tripped. Preferably, the trigger mechanism is provided by a light mean sensor in which the light beam is broker by an intruder passing a selected entry point.
