a sixth sensor oriented to detect an object above the floor in the corridor, wherein the sixth sensor is operatively connected to the controller and the controller is configured to one of: a) turn off the sixth sensor when the fifth sensor detects an object on the floor and b) not respond when the sixth sensor detects an object above the floor when the fifth sensor detects an object on the floor.
6 . The door system of claim 1 , wherein the first and second sensors are curtain sensors.
7 . The door system of claim 1 , further comprising an alarm system operatively connected to the controller, wherein the controller is configured to activate the alarm system depending upon data received from the first and second sensors.
8 . The door system of claim 1 , further comprising a remote user input device operatively connected to the controller to input data to the controller.
9 . The door system of claim 1 , further comprising a data transmitter operatively connected to the controller, the data transmitter configured to transmit data from the controller to a remote destination.
10 . The door system of claim 1 , wherein at least one of either an audio and visual indicator is operatively connected to the controller, and the controller is configured to activate the at least one of either the audio and visual indicator to provide instructions to people located proximate to the door system.
11 . The door system of claim 1 , further comprising a camera operatively connected to the controller, the camera configured to provide data to the controller.
12 . The door system of claim 1 , further comprising a third door located between the first and the second doors, the third door located at a middle portion of the corridor.
13 . A method of providing a secure exit comprising:
locating a first door at a first end of a corridor having a floor;
locating a second door at a second end of the corridor;
mounting a first sensor to detect an object on the floor;
mounting a second sensor to detect an object in the corridor located somewhere in the corridor other than the floor; and
operatively connecting a controller to the first and second doors and first and second sensors and configuring the controller to one of: a) turn off the second sensor when the first sensor detects an object on the floor and b) not react when the second sensor detects an object above the floor when the first sensor detects an object on the floor.
14 . The method of claim 13 , further comprising detecting motion outside the corridor in a direction toward the corridor and doing at least one of: 1) closing at least one of the first and second doors when movement in a direction toward the corridor exceeds a threshold amount and 2) keeping an already closed first and second door closed when movement in a direction toward the corridor exceeds a threshold amount.
15 . The method of claim 13 , further comprising:
mounting a third sensor to detect an object on the floor;
mounting a fourth sensor to detect an object in the corridor located somewhere in the corridor other than the floor; and
operatively connecting a controller to the first and second doors and third and fourth sensors and configuring the controller to one of: a) turn off the fourth sensor when the third sensor detects an object on the floor and b) not react when the fourth sensor detects an object above the floor when the third sensor detects an object on the floor.
