Lifting and lowering of the box is carried out by winding special slings on the shaft. The canvas is placed in a box and it is not visible in the raised state.
Fire resistance limits:
- EI60 (with one-way use of water irrigation from existing sprinkler or drencher fire extinguishing systems of the building, water consumption is not less than (0.08 *h) l/m * s per linear meter in width, where h is the height of the curtain in meters).
- EI180 (with one-way use of water irrigation from existing sprinkler or drencher fire extinguishing systems of the building, water consumption is not less than (0.08 *h) l/m * s per linear meter in width, where h is the height of the curtain in meters).
- E60 without irrigation.
Structurally, the system is made in the form of a rectangle, a polygon, in the form of U- and L-shaped shapes.
Execution with a loophole door is possible.
Lifting and lowering of the curtain is carried out only by a 220 volt motor and by 380 volts for large sizes.
In case of power outages, the backup power of the electric motor from the battery is provided.
Places of application of the Fireshield-S "Accordion"
- system fencing of elevator halls;
- protection of atriums;
- protection of escalators.
Smoke-proof curtains "Accordion" E 60
If there is a need to make smoke-proof curtains of a complex shape, then it is possible to use an Accordion-type design for smoke-free curtains that will prevent the spread of smoke around the room for 60 minutes. The main difference from the fire curtains "Accordion" - lowering does not occur to the floor, but to a given height, about 2 meters to the floor.

Canvas
Material: Firetex 1100 (manufactured in Germany);
Fabric weight: 440-660 g/m2;
Material thickness: 0.63mm;
The canvas is single-layered. The fabric is certified as non-flammable and non-toxic.
To obtain high resistance, when exposed to high temperatures, a thin stainless wire is woven into each fiberglass thread.
Box
It serves to accommodate and protect the details of the lifting mechanism of the web and consists of U-shaped panels bent from galvanized steel with a thickness of 1 mm. The boxes are connected to each other by means of connecting plates.
Color version: any color on the RAL color scale or galvanized steel.
Mounting options for the accordion screen
The standard installation scheme is to the ceiling, but an individual option is possible, at the same time, the degree of fire resistance of the structure to which the installation is carried out should not be less than the degree of fire resistance of the curtain itself.
The main advantage of the flexible fire-fighting system Fireshield-S "Accordion" is that it is unique in its places of application and methods of fastening.
Where is it installed?
This type of curtain is most often installed in shopping and entertainment and office centers. The accordion curtain solves the problem with the separation of large fire compartments and the isolation of escalators. A fire curtain of a complex shape is, most often, the only solution that will not spoil the design of a modern shopping center and will help fulfill the fire protection requirements for passing the inspection by the Ministry of Emergency Situations. When closed, the structure does not stand out from the general design (it is possible to manufacture a stainless steel box or RAL painting) and is located under the ceiling.
