An access control device including an electromagnetic lock module for selectively locking and unlocking a door in a door frame is provided. The access control device provides a lower profiled electromagnetic lock module to improve the aesthetics and functionality of the module, supports and integrates modern accessories such as CCTV, CCD cameras, passive motion detection with automatic background correction, digital notification display, automatic source voltage selection, door and lock status indicators, and ease of installation. The present invention further provides components and circuitry to enable connection of the electromagnetic control module to 12 or 24 volts DC or to an unfiltered rectified AC power supply.

Access control devices of the electromagnetic lock module type

An access control system including bi-directional communication between a controller and peripheral authentication devices utilized for selectively accessing a locked door is provided. The access control system provides components and circuitry to enable a user to securely assign and designate any card reader compatible card as an appropriate programming card and thereby activate or deactivate users and/or cards. The present invention further provides encrypted communication between the controller device and a PC.

A vertical door locking system includes a door lock with a deadbolt that moves horizontally, a striker with an upward facing strike opening that vertically receives the deadbolt and a lock controller. The striker includes an electrically operated catch to engage and release the deadbolt. The door lock and striker are mounted opposite each other, one to the vertical door and the other to an adjacent fixed mounting point. The lock controller electrically operates the striker to release the deadbolt and allow it to move vertically out of engagement with the striker for primary access to a secure area and the door lock allows the deadbolt to be retracted horizontally away from the striker for secondary access. A remotely located control system optionally controls the lock controllers of multiple doors and a central office control system is optionally connected to multiple remotely located control systems.
