FM1 fire curtain

A fire curtain is used where, if there is a fire, it is necessary to create a temporary barrier within an opening which seals off the area on fire. The curtain descends and prevents any fire and smoke from spreading from one area to another. It also allows people access to protected escape routes without any loss of fire resistance. A FM-1 fire curtain comprises a flexible fire-resistant fabric which is wound around a circular tube. Upon receiving a signal from the fire alarm system or on loss of power the curtain automatically unwinds to its operational position. FM-1 fire curtains have been tested as fire barriers in accordance with EN 1634-1, providing protection for a defined period and at a defined maximum temperature.
