Abstract
Provided are electronic door locks, systems, and computer implemented methods of use. In one example, the electronic door lock includes a locking mechanism configured to change a state of a door of a room between a locked state and an unlocked state. The electronic door lock further includes a communications interface configured to communicate wirelessly or wired with one or more fire devices. The one of more fire devices are configured to transmit a wireless or wired alert signal to the communications interface in response to detecting an occurrence of fire. The electronic door lock further includes a display unit configured to display an alert upon the communications interface receiving the wireless alert signal from the one or more fire devices, and configured to display an indication as to occupancy of the room.
