Visual lockdown notification and alert device, electronic door stop remote broadcast device, silent broadcast signal-activated electronic door stop, and sound-activated remote release electronic door stop

A visual lockdown notification and alert device that provides visual notification of a lockdown in progress, the visual lockdown notification and alert device comprising:

• a printed circuit board (PCB) comprising internal PCB components;
• a programmable micro-processor that is disposed on the PCB and is programmable to define the visual lockdown notification and alert device as a particular type of device in a wireless personal area network (PAN);
• an outer assembly cover that encloses the PCB and internal PCB components;
• a plurality of micro-buttons to trigger notification and alert actions, wherein the plurality of micro-buttons comprise a first micro-button that is configured to trigger a retract notification to an electronic door stop, a second micro-button that is configured to trigger an extend notification to the electronic door stop, and a third micro-button that is configured to trigger an alert action to initiate an emergency broadcast signal to other devices defined in the wireless PAN;
• a plurality of circuit relays that are disposed on the PCB and are configured to actuate notification and alert actions triggered by the plurality of micro-buttons;
• and
• an LED strobe globe light that flashes a visual notification and alert when a lockdown situation is in progress.
