A barrier comprising a roller, a curtain 2, a bottom bar and a friction brake. The curtain arrangement 1 includes a curtain 2, which when not deployed is wound on a roller 4. The roller is provided within a headbox 6, in a ceiling 8. The curtain is provided with a bottom bar 10 which weighs the curtain for descent, but can also be used to close the headbox when the curtain is retracted onto the roller. Side guides 12 are also provided to contain side edges 14 of the curtain. They extend from the headbox 6 on the ceiling to the floor 18. The curtain is held in its retracted position on the roller, by a fusible link 20. An extension 22 of the roller 2 is provided extending out of the headbox 6. The fusible link 20 is provided between the outside of the headbox and the extension 22 of the roller. A peg 24 mounted on the headbox 6 holds one portion 26 of the fusible link, while the other portion 28 of the fusible link is connected to the extension. These portions are held together by a material 30 having a low melting point range typically between 57-150°C. This acts to hold the curtain on the roller under normal condition, preventing rotation of the roller within the headbox, but on sufficient temperature rise, the material 30 will melt, releasing the portions 26, 28 of the fusible link, allowing rotation of the roller and deployment of the curtain.

A curtain is wound on a roller (2), provided in a head box (4), mounted in a ceiling (6). The curtain is also provided with a bottom bar (10). When the curtain is drawn up onto the roller, the bottom bar (10) can be used to close the head box (4). When deployed the bottom bar provides stability to the descending curtain, and in full deployment rests on the floor.

Typically this will be by sewing (32), but also may be rivets or other form of heat resistant connection. The strip(s) are also connected to the bottom bar. A cable (34) is attached to the strip(s), usually through a rivet, but any other form of secure attachment may be used. The cable is then connected to the bottom bar, via a spring (36).

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 The barrier also includes a release such that in the event of a fire the stops (14) can be withdrawn from their position by pivoting out of the way of the bottom bar either in the plane parallel to the bottom bar (10), or by rotation about their end to a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.

Fire and smoke barriers are deployed automatically on detection of fire of smoke. This can result in evacuees being on the wrong side of a deployed barrier and needing to evacuate through the barrier. The barrier includes a curtain rolled on a roller in a head box, a pair of side guides and a bottom bar. At least one of the side guides being partially movable, temporarily opening the barrier to allow the escape of an evacuee. Both side guides can be movable, allowing the barrier to swing from its top. Alternatively one side guide can be hinged to a wall with the other being able to move away from its wall, the head box joining the tops of the side guides. The barrier opens like a door to allow escape of an evacuee. The door having a closure spring to ensure it returns to its closed position.
An alarm system for a smoke or fire barrier, including alarm circuits have a normally closed switch position. A control circuit connected to the alarm circuits applies a voltage to create a non-activation situation or remove a voltage to create an activation situation when the switch is open. The alarm circuit further including either a series connected resistance or a normally open switch position in parallel to the normally closed switch position, to create a “fault” condition in the absence of detection of the resistance, or an open switch position and a closed switch position.
A twin roller smoke or fire barrier having: two parallel rollers and a curtain comprised of narrow curtain portions rolled on the rollers and arranged along the length of the rollers of alternate rollers with end margins overlapping opposite each other; the barrier including: a mechanism for varying separation of the rollers by at least the change in the overall diameter of one roller and its curtain portions between wound-up and unwound states, the mechanism including: movable supported roller or rollers; whereby in the unwound state of the curtain, the overlapping margins abut or at least are separated by a negligible amount at the rollers.
