The shutter is constructed from interlocked, baked painted galvanized steel laths which form a sealed curtain. The shutter winds back on a horizontal steel shaft tensioned by torsion springs.
The shutter is electrically operated and includes a reserve chain for manual operation.
Edge fasteners made from cast steel are attached to the edges of the laths and fitted into the curtain guides.
Bottom edge of curtain- double steel angle for increased resistance at the bottom of the curtain.
Upper Hinge Fasteners- made from thick-walled steel fitted with bearings- matching the size of the door.
Guides for the curtain made from 3- thick-walled steel angles forming a rail set apart from the wall. At the top edge- a stopper for stopping the door at the bordering point of the light opening.
Above the drum- cylindrical steel protective cover made from 0.6 mm galvanized steel.
Method of Operation– The fire-resistant shutter automatically shuts in the event of fire.
The torsion springs are under tension and are connected to a chain anchored to the wall, with one of the links being a multi-use electronic fuse that melts at a temperature of 70’C. The detachment releases part of the spring’s action and the curtain drops in a controlled manner, closing the opening.
Operation– Electrically operated via a three-phase motor with suitable power supply corresponding to the size of the shutter, with a reserve chain for manual operation included.
Automatic stopper to prevent opening of the door from the outside (this unit serves as a lock in place of the existing lock).
Control box for electrical operation by switches located on the wall, with operation buttons: up, down and stop.
Installation– The shutter is to be installed by a professional installer certified by the RB-Group and to be anchored to the frame of the opening according to RB-Group instructions.
