Abstract: A door barricade alert system includes a door barricade device, a sensor, and a communication system. The door barricade device is normally positioned in a stored, non-installed position. The sensor is associated with the door barricade device in the stored, non-installed position. The communication system is associated with the sensor at one end and with a target at the other end. When the door barricade device is in close proximity to the sensor, the sensor is not activated and when the door barricade device is moved from close proximity to the sensor, the sensor sends a signal through the communication system to a target.

Abstract: A door barricade includes a base member and a securing mechanism. The base member has a size that permits it to be positioned under a door, with a first upwardly extending portion positioned on the base member and a second upwardly extending portion positioned on the base member. The first and second upwardly extending portions are spaced a distance from one another that is greater than or equal to a width of a door. The securing mechanism is coupled to the base member for mating with a floor. The base member and the securing member together serve to barricade a door such that the door will not move even upon the application of significant force when the securing mechanism is fixedly coupled to a floor.
