Smokemaster SM5 automatic smoke curtain

A Smokemaster SM5 automatic smoke curtain prevents the movement of smoke and heat generated by a fire from one area to another by channelling or containing the smoke and heat.

The smoke curtain has fixing options to suit all types of ceiling configurations and can be integrated into either a suspended or a solid ceiling. It remains hidden until required.

The smoke curtain comprises a flexible heat resistant fabric that is impervious to smoke and hot gases, wound around a circular tube. Upon receiving a signal from the fire detection or on loss of power the curtain automatically unwinds to its operational position.
