Access control vestibule
First Claim
1. An access control vestibule, comprising:
- a metal frame including a side wall frame section;
the metal frame defining an access control chamber;
an entrance door and an exit door mounted on opposite ends of the access control chamber to permit access into and exiting from the access control chamber;
a metal detector disposed to detect metal within the access control chamber;
a bullet resistant transparent glass mounted in the side wall frame section;
control means to prevent both doors from being opened at the same time;
seismic detector means to determine if an earthquake or an explosion is occurring;
the seismic detector means and the control means being operatively connected; and
whereby when the seismic-detector means determines that an earthquake or an explosion is occurring, the control means unlocks both doors.

Abstract
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.

41. An access control vestibule, comprising:
-
an entrance door and an exit door; an access control chamber formed between the doors; lock means to lock both of the doors; control means to prevent both doors from being opened at the same time; the control means being operatively connected to the lock means; and vibration sensing means to determine if an earthquake or an explosion is occurring; the vibration sensing means being operatively connected to the control means; whereby when the vibration sensing means determines that an earthquake or an explosion is occurring, the control means unlocks both doors. - View Dependent Claims (42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 60, 61, 62, 63, 64, 65)
