Product NameMulti leaf smoke exhaust outlet Details:
positive pressure air supply outlet： Function: When a fire occurs, the internal motor will open the air vent, the temperature and smoke sensing or manual fire alarm will be activated, the positive pressure fan at the top of the tower will automatically open, and the supply shaft will be pressurized for air supply. The front room of the staircase will pass throughpositive pressure air supply outletIt will continuously supply air to the front room to maintain positive pressure, ensuring that smoke does not spread in this area and providing space for people to escape. When the temperature exceeds 280 ° C, there is no possibility for people to escape. The internal fuse will melt, and the air vent will automatically close to prevent the spread of fire. Application: According to the National Code for Fire Protection and Smoke Exhaust Design of High rise Buildings, independent mechanical smoke exhaust systems should be installed in the following areas 1: Smoke proof staircases, fire elevator lobbies, or shared lobbies that do not have natural smoke exhaust conditions. 2: The smoke proof staircase with natural smoke exhaust does not have a front room with natural smoke exhaust. 3: A closed refuge layer. In the above three situations, a mechanical pressurized air supply system is virtually installed. Its end ispositive pressure air supply outletBelow are the styles of the product and drawings |

Product NamePlate type smoke exhaust outlet Details: Scope of use: The smoke exhaust outlet of the smoke exhaust system installed in corridors or smoke proof front rooms, as well as windowless rooms, can be suspended from the ceiling or installed on the side wall. Features 1. Normally closed, with a DC24V electrical signal from the control center, the smoke exhaust vent quickly opens. 2. Remote manual opening. 3. Remote manual reset. 4. Output the activation signal and interlock the relevant equipment. 5. The plate type exhaust outlet has the function of closing again when the flue gas temperature reaches 280 degrees after opening. Production of fire dampers and smoke exhaust dampers: 1. In case of fire, the frame (shell) and blades should be able to prevent deformation and failure, and the thickness of their plates should not be less than 2mm. 2. Fusible parts should be standard products recognized by the door, and their melting point temperature should comply with the design specifications. 3. The valve action should be reliable, and it should be tight when closed. Its allowable air leakage should comply with relevant regulations. |
