Abstract
The present invention is a roll-up alarm screen assembly for use in a frame. The frame has a first magnet disposed in its bottom portion and a second magnet disposed in its top portion. The roll-up alarm screen assembly includes an alarm screen and a roll-up mechanism which rolls the alarm screen up and down. The alarm screen includes a screen mesh and a conductive wire which is mechanically coupled to the screen mesh. The roll-up alarm screen assembly also includes a first magnetic coupler and a second magnetic coupler. The first magnetic coupler electrically couples severed ends of conductive wire when the first magnetic coupler is disposed adjacent to the first magnet. The second magnetic coupler electrically couples severed ends of conductive wire when the second magnetic coupler is mechanically coupled to the roll-up mechanism and is positioned so that the second magnetic coupler is disposed adjacent to the second magnet in order to detect any movement of either the roll-up mechanism or the screen mesh.
