1. Between the auditorium and the stage, a fire curtain is set at the entrance of the stage, which is a special door for safety and fire prevention. In the event of a fire accident in the theater or at the end of each performance, the fire curtain is lowered, separating the stage and the auditorium into two fire zones.
2. In case of emergency, the fire curtain must be able to stay within 45s from the time of release. Fall into place by gravity: when it is 2.5m away from the main stage surface, the damping will start to fall, and the time shall not be less than 10s. An electric lifting device is arranged on the top height of the grid, which can be electrically controlled to rise and manually lowered.
3. A running guide rail is provided on both sides of the fire screen, and a sealing device should be installed around the screen body and the building wall, so that the fire screen can effectively seal the smoke and fire when it is in the descending position.

3. A running guide rail is provided on both sides of the fire screen, and a sealing device should be installed around the screen body and the building wall, so that the fire screen can effectively seal the smoke and fire when it is in the descending position.
4. The fire resistance limit of the fire curtain shall meet the international standard and the relevant domestic and local fire protection regulations. The fire screen and guidance system should be able to withstand the pressure difference between the auditorium and the stage.
5. The fire curtain is composed of screen body, guide rail, balance weight, driving device, hoisting system, damping device, etc. It consists of the following parts:
The curtain body is a steel structure frame filled with fireproof and flame retardant materials, which can withstand horizontal and vertical forces
The winding system consists of a motor, a reducer, a brake, a coil, a mechanical manual release assembly, etc. The damping force of the descending damping device is released and the damping position is adjustable. Guide rail and sealing device; Pulley assembly; Counterweight, counterweight frame and guide (if necessary); Wire weaves and fittings.
6. Deep working disc with lift, drop and emergency stop buttons can achieve deep working in situ. The manual release mechanism is arranged on the inside of the platform mouth, and there is operation control and operation status display in the fire control room.
