【 Can fire doors be used as shutters? 】

  First of all, we need to understand what is fire shutters: installed on the window with fire protection requirements, and at the external wall vents. The fire valve shutter consists of two parts: electric fire valve and aluminum alloy fixed return air outlet.

  (1) The valve is normally open or normally closed, when the air temperature reaches 70℃ or 280℃, the temperature sensor operates, and the valve is closed or opened;

  (2) The valve can also be closed or opened by DC24V power supply;

  (3) Manual closing or manual overlap;

  (4) It can also pass DV24V electric overlaying, eliminating the trouble of manual overlaying (automatic mechanism type);

  (5) Manually adjust the opening degree of the blade in the range of 0° ~ 90°;

  (6) Output valve close or open signal, can be interlocked with other fire protection equipment.  

  In addition, the fire window is divided into two categories can be opened and not open, the fire window can be opened simply means that the window sash can be opened, and the fire window can be closed under the action of the fire window opening and closing device. As for the non-open fire window, it is the opposite of the first type, which refers to the fire window whose sash cannot be opened, that is, the surrounding seal is fixed. The new fire window standard is that the fire wall should not open the door and window openings, when it must be opened, should be set up fixed or fire can automatically close the fire door, window, automatic close, in the fire window refers to the window opening and closing control device, simple fire window fuse device and fire window temperature control support rod, at 68 degrees Celsius will occur deformation or fragmentation, close the window, Advanced fire linkage control window close device and thermoelectric double control window close device, through the fire signal combined with temperature change for double control.

  According to the above description, blinds can be set on the fire door. But does it apply in Macau?

  The standard used in the regulations of Macau is fire integrity and heat insulation, such as only using a single layer of louver without adding a fire board, when the temperature needs to reach 1000℃ during the fire inspection process, the single layer of steel plate will react with heat, and the position of the louver is easy to overtemperature and fire up, and then the test fails.

  Therefore, we recommend that fire doors do not add louvers to reduce the possibility of accidents.
