Abstract

A security entrance system for controlling access from an infeed area (98) to a protected area (100) has a structure (24) defining a chamber disposed between the infeed area and the protected area, with first doors (38) at the infeed end of the chamber second doors (46) at the protected area end of the chamber. A person entering the protected area must pass through a contraband detector such as a metal detector (90, 92) and enter the chamber. If no alarm was provided by the detector, the doors allow exit from the chamber into the protected area. If an alarm was provided by the metal detector, the doors only allow the person to pass back from the chamber into the infeed area and away from the protected area. The chamber is weighed or otherwise examined after at least some cycles of operation to assure that no contraband was concealed within the chamber.

Claims

1. A security entrance system for restricting access from an infeed area to a protected area comprising:

a) a structure defining an enclosed chamber with a first opening connecting the interior of said chamber with said infeed area and a second opening connecting the interior of the chamber with said protected area, said structure including one or more first doors movable between a closed position in which said first doors block said first opening and an open position in which said first doors do not block said first opening, and one or more second doors movable between a closed position in which said second doors block said second opening and an open position in which said second doors do not block said second opening;

b) a contraband detection system operative to detect contraband entering said chamber a said infeed end;

c) a chamber monitoring system connected to said structure for measuring at least one characteristic of said structure defining said chamber; and

d) a controller connected to said doors, said detection system and said chamber 5 monitoring system, said controller operating cyclically, each cycle including allowing said first door to open to allow a person entry to said chamber, actuating said detection system to scan said chamber for contraband entering the chamber and allowing said second door to open if no contraband is detected and said first door is closed, thereby allowing the person entry to the protected.
