An access control chamber security system with a security chamber having an aluminum frame and an entrance door and an exit door, a metal detector located within the access control chamber to detect a weapon being carried within the chamber, locks on the doors and a control device to prevent the doors from being opened at the same time or prevent the exit door from opening when a weapon is detected, and further including a side frame member with a cutout section having an insulated member placed therein to provide an open electrical loop in the side frame member, the metal detector having a plurality of coils located in a plurality of zones, a three second time delay from when the manually operated exit door is opened to when the lock on the exit door is re-activated, ballistic fiberglass disposed within a hollow section of the aluminum frame members, floor contact pads with nitrogen disposed within the pads surrounding the metal plates formed therein, a floor contact pad having a plurality of induction coils therein to act as a metal detector for a weapon placed on the floor, a vibration sensor or seismic detector associated with the controls of the access control chamber system to unlock the doors in the event of an earthquake or a bomb explosion, and the lock box covering up the magnetic locks having bullet-resistant capabilities. The vibration sensor includes a magnet hanging from a thin wire, and in close proximity to a normally opened contact switch such that displacement of the magnet closes the contact switch.
