A fireproof curtain is a specialized door for safety and fire prevention. In the event of a fire accident or at the end of each performance, the fireproof curtain falls down, separating the stage and the audience hall into two fireproof areas.

In emergency situations, the fire curtain can descend into place by gravity within 45 seconds after activation; When the distance from the main stage is 2.5 meters, the damping begins to decrease to avoid injuring people and the stage. The fire resistance limit of the fireproof curtain meets the relevant national standards and can withstand the pressure difference caused by fire between the audience hall and the stage.

There are running rails on both sides of the fire curtain, and sealing devices are installed around the curtain and the building wall to effectively seal smoke and fire when the fire curtain is in the lowered position.

The control panel with up, down, and emergency stop buttons allows for on-site operation. The manual release mechanism is located on the inside of the platform and has operation control and status display in the fire control room.

The fire curtain consists of a curtain body, guide rails, balance weights, hoisting systems, damping devices, protective devices, sensors, etc.

Specifically:

·The curtain body is a steel structure frame wrapped in steel plates and filled with fire-resistant and flame-retardant materials.

·The hoisting system consists of an electric motor, a reducer, a brake, and a drum. Equipped with a mechanical manual release device.

·The damping force and damping position of the descending damping device released by the fire curtain can be adjusted.

·Guide rails and sealing devices.

·Pulley components. ·Balance weight and guide rail. ·Steel wire rope and accessories.
