Abstract
A wireless access control system may include a remote access device and a lock assembly. The lock assembly may include a lock, a door position sensor, interior and exterior directional antennas, wireless communications circuitry, a touch sensor, and a lock controller. The lock controller may unlock the lock based upon the touch sensor, determine when the door is closed after being opened based upon the door position sensor, and determine whether the remote access device is in an interior or exterior based upon the directional antennas. The lock controller may also lock the lock when the door is closed and when the remote device is in the interior. The controller may operate in an automatic calibration mode to generate adjusted interior and exterior received signal values and, based upon the adjusted received signal values, enable and disable unlocking when the remote access device is in the exterior and interior, respectively.
