Abstract
Barrier systems and associated methods, including vapor and/or fire barrier systems, are disclosed herein. One aspect of the invention is directed toward a barrier system that includes a barrier coupled to a spool. The barrier is positioned to be wound onto and off of the spool as the barrier moves between a deployed position and a retracted position by a drive assembly. The system further includes a seal assembly positioned in a housing and contacting the spool to create a barrier to smoke and vapor migration through the housing. The system still further includes a sensor operably coupled to a control system and positioned to sense barrier position as the barrier moves between the deployed and the retracted positions.
