Pressure delivery outlet outlet pressure multi-leaf multi-leaf smoke exhaust port (air) port is made up of body and the operating unit and the composition of aluminum packaging finishes, according to the operating system is divided into four categories: (1) multi-leaf smoke (air) port Figure, its operating unit mounted directly on the body. Fire alarm, the solenoid valve opening action rope linkage system output signal line. (2) Remote control multi-leaf smoke (air) mouth, its operating system by coupling the rope for remote control. Fire alarm, solenoid actuated to make the red button on the remote operating device, manually open the valve, linkage control output signal line. (3) multi-leaf smoke (air) port, its operating unit mounted directly on the body. Fire alarm, solenoid actuated to make the red button on the remote operating device, manually open the valve rope. 2800C fuses close the valve damper, the output signal and the open joint control, other equipment and fire protection systems interlock. (4) Multi-leaf smoke (air) port, its operating system by coupling the rope for remote control. Fire alarm, solenoid actuated to make the remote operating device red button to manually open the valve, 2800C fuses close the valve and linkage control signal output on line, other equipment interlock and fire protection systems. (5) Remote control multi-leaf smoke (air) port inspection door can be reduced to the minimum 50, nearly controlled multi-leaf smoke (air) port inspection door can be reduced to the minimum 50. Multi-leaf smoke (air) port has a form of a rectangular fire dampers installation, discrete and horizontal design please specify or install mode.
