Fire Curtain

Similar in basic design to a roller shutter, a fire curtain comprises a fabric made of heavyweight glass fiber, reinforced with stainless steel wire, and coated with a formulated fire retardant aluminum pigmented polyure-thane coating. The main function of fire curtains is to use them instead of masonry in building to prevent the spread of fire between defined fire zones. These curtains are available in two types, fixed and movable. The movable curtain has control systems that allow a curtain to descend via a 24-volt gravity fail-safe motor to compartmentalize a building. As well as a control panel that gives the fire curtain the ability for single descent or descend partially hold and continues descent, additional functionality can be achieved with the installation of egress switches, access switches, and single and light curtain obstruction warnings are also available. The quality and Reliability of the curtains’ perfor-mance are tested according to standard EN BS 1634-1. These curtains, which are classified according to EN13501-2, have EXX classification, which means maintaining the integrity at a specific time XX, EWXX, which means maintaining the integrity and radiation protection at a specific time, and EEXX, which means maintaining the integrity insulation.
