2) Remote-control Multi-blade exhaust smoke outlet. Its operation device remote control by the connection of wire ropes. Once fire signal appear, the electromagnet will used remote device to operate on the red button, manually open the damper, and output signal-line linkage.

3) Its operation device is installed in the body. Once fire signal appears, the electromagnet will use remote device to operate on the red button, manually pull the rope to open the damper, and output signal-line linkage. Rate of operation at 280℃, the damper closed, open output signal and linkage control, and interlock with other device in the fire-proof system.
