Abstract
An access control assembly is described herein. The assembly includes an actuator, a communication interface, a display, and a processor. The actuator is configured to open and close a latch to secure a door of the enclosure. The processor can be configured to receive a user credential for accessing the enclosure, validate the user credential for accessing the enclosure, trigger the actuator to open the latch, thereby allowing the door to be opened, and trigger the actuator to close the latch after detecting that the door is closed, thereby securing the door.
Claims20
An access control assembly comprising:
- an interface module comprising a processor and a first memory device comprising a local cache for storing inventory information, and configured to couple to an outer surface of an enclosure door of an enclosure, the enclosure door being movable to enclose an enclosure volume of the enclosure, wherein the interface module lacks any user-actuated keys for user input and comprises a keyless sensing input configured to detect input for non-keypad-based access control, the interface module further comprising a wireless communication interface within a housing of the interface module and configured to wirelessly connect to a mobile device or another interface module via the wireless communication interface and communicate the inventory information from the local cache to the mobile device or the another interface module;
- a second non-volatile memory device;
- a latching module configured to couple to an inner surface of the enclosure door within the enclosure volume opposite the outer surface and the interface module, the latching module comprising a latching member and a latch actuator configured to extend or retract the latching member based on a signal received through the enclosure door indicating to lock or unlock the enclosure door from within the enclosure volume, the signal being transmitted by the latching module based on the detected input for non-keypad-based access control or an access communication received via the wireless communication interface;
- a first power supply enclosed within a housing enclosure of the interface module and configured to provide power to the latching module;
- a manual lock coupled with the latching module and operable to move the latching member from at least a locked state to an unlocked state irrespective of a status of the first power supply;
- and
- a second power supply configured to provide power to log access via the manual lock in the second non-volatile memory device when the first power supply is unavailable.
