| 1. A power management lock system for use in a multi-unit building, including a server associated with a network, the system
comprising:
an electronic lock unit including a control assembly, a locking mechanism configured to lock and unlock a door providing an
entrance to a single unit of the multi-unit building, and a credential sensing mechanism to enable the door locking and door
unlocking operations of the locking mechanism by a reading and a verification of data stored in a card of a potential occupant
of the single unit, the control assembly, the locking mechanism and the credential sensing mechanism being disposed at the
door;
a communications transceiver to communicate door data and electronic lock unit power data with the server of the multi-unit
building; and
a sensor disposed in logical communication with the control assembly and configured to sense whether the door is open or closed
and to indicate to the control assembly when the door is open,
wherein said control assembly is configured to receive the open door indication from the sensor and, upon receipt of the open
door indication from the sensor, to cease provision of electronic power to the locking mechanism and the credential sensing
mechanism and to simultaneously maintain provision of electronic power to the communications transceiver.
