A fire or smoke barrier has a head box (4), a drum (6) holding a curtain (8) and a bottom bar (10) for weighing the curtain (8). A stop mechanism includes a series of stops (14) preventing the bottom bar (10) of the curtain (8) from descending. The stops (14) being connected together, and held in non-deployment position. The barrier also includes a release such that in the event of a fire the stops (14) can be withdrawn from their position by pivoting out of the way of the bottom bar either in the plane parallel to the bottom bar (10), or by rotation about their end to a position 90° to their original position. |
