Abstract
An electromagnetic door lock system employs an on-board microprocessor which is mounted in the housing for the electromagnet. The microprocessor is pre-programmed with possible operating parameters which are then selected at the installation site. In one embodiment, a contact activatable data reader is mounted at the housing to provide various input data for the microprocessor. The microprocessor is also capable of being interrogated to reveal the preset operating parameters and other information, including the identification of individuals requesting to egress through the associated doorway.
