Rigid Fire Curtain (Lift Type)
Specifications
- Complies with national standard GB36726-2018 Stage Machinery - Rigid Fire Isolation Curtain A well-equipped large theater, must be equipped with a fire curtain with automatic and manual control for fire extinguishing and flame isolation, In case of a fire alarm, the fire protection system extinguishes the fire. The fire curtain is located inside the stage proscenium, There is an electric lifting device on the equipment floor. It can be raised and lowered electrically, and can also be lowered manually. The curtain body lifting drive uses a traction type with counterweight, The motor reducer raises the entire curtain body above the proscenium, and it is held in place by an electromagnetic brake. In case of fire the curtain body is lowered, The curtain body descends in a damped state, with two-stage speed change during descent. The full descent time is 30-50 seconds. Both sides of the curtain body are steel plates, filled with rock wool inside.
- The fire curtain body and hydraulic damping system are designed according to national standards.
- Counterweight type lifting drive, the curtain body is a steel structure. The curtain body structure is filled with flame-retardant mineral wool, the curtain surface is coated with fireproof paint. Elastic non-combustible material is installed where the bottom of the curtain body contacts the stage floor.
- The fire curtain control box is located at the proscenium, It can control the raising and lowering of the curtain body electrically, and can also lower the curtain body manually. The control box has a mechanical handle to control the curtain descent, The curtain body descends by its own weight, The descent speed is automatically controlled by the damper with two-stage speed change. The curtain can also be lowered directly from the fire control center. Main technical parameters of the fire curtain:
- Electric lifting speed: 0.10 m/s
- Load: self weight Allowable horizontal pressure: at a calculated temperature of 300 degrees, the curtain body withstands a horizontal pressure ≥0.3kN/m2
- Emergency closing time: 30~45s, In an emergency, the fire curtain can, within 30~45s after activation, descend to position by gravity. Damped descent starts at a vertical height of 2.5 above the main stage floor, The descent time shall not be less than 10s.
- Fire resistance time: more than 60min
- Drive mode: Electric steel wire rope with hydraulic damping Complies with national standard GB36726-2018 Stage Machinery - Rigid Fire Isolation Curtain
