First Claim
Patent Images
1. A security system for operation in response to an attempted egress through a door of at least one preselected person, the security system comprising:
- a security device associated with the door for energization upon the attempted egress through the door of the at least one preselected person;
a permanent magnet having a magnetic field and carried by the at least one preselected person;
means associated with the door for generating a current in response to the magnetic field of said permanent magnet when it is passed adjacent said generating means by the at least one preselected person upon the attempted egress through the door; and
means operable generally in response to the current generated by said generating means for effecting the energization of said security device.

Abstract
A security system operates in response to an attempted egress through a door by a preselected person. The magnetic field of a permanent magnet is passed in a preselected spatial relation which respected a current generating device to generate a current upon the attempted egress through the door by the preselected person carrying the permanent magnet, and a security device is energized to lock the door upon the establishment of the generated current. A method of operating a security system is also disclosed.

9. A method of operating a security system in response to an attempted egress through a door of at least one preselected person, the security system including a permanent magnet having a magnetic field and carried by the at least one preselected person, a security device for the door, a current generator, and a switching device having a plurality of switching modes, the method comprising the steps of:
-
passing the magnetic field of the permanent magnet within a preselected spatial relation adjacent the current generator upon the attempted egress through the door by the at least one preselected person; establishing a current in the current generator in response to the passing step; switching the switching device to one of its switching modes upon the establishment of the current in the current generator; and effecting the energization of the security device in response to the switching step. - View Dependent Claims (10, 11, 12, 13)
