Damper Usage (1) usually was turned on, when the fire within the exhaust pipe when the flue gas temperature reaches 280 degrees off, and to meet the leakage amount of smoke and fire integrity requirements within a certain period of time, from the effects of smoke fire retardant ( 2) allows the valve is closed by DC24V power; (electric type smoke damper) (3) or manual reset manually shut down; (4) closed DC24V electric reset; (automatic type smoke damper is suitable for manual operation inconvenience where) (4) output valve closed signal can be interlocked with other fire-fighting equipment. Features 2.1 damper function normally open type smoke damper functions are as follows: 2.1.1 usually was normally open state, when the fire broke damper samples from the control center after DC24V power output, the valve automatically closes when the pipe 2.1.2. When the temperature reaches 280 ℃, fuse action, the valve automatically closes. 2.1.3 Output signal the valve is closed, interlocking exhaust fan stops. 2.1.4 manually close the damper, manually open 2.2 normally closed smoke damper function as follows: normally closed smoke damper, also known as secondary smoke damper action. 2.2.1 usually was normally closed when the fire broke out, by the control center DC24V power input dampers installed quickly open the valve. 2.2.2 output valve open signal, interlock control exhaust fan fire. 2.2.3 manually open the manual reset closed. 2.2.4 when the pipe temperature reaches 280 ℃, the fuse action, the valve is closed again. construction and installation of fire dampers with editing 1 fan, exhaust fan interlock. 2. The operation of the valve mechanism side should be not less than 200mm of headroom to facilitate maintenance. 3. The valve must be checked before installation of the valve operating mechanism is intact, the action is flexible and effective. 4. duct segments damper should be installed in close proximity to the wall or floor of the damper functionality Fire dampers on both sides of the partition wall from the wall surface should not exceed 200mm, dampers on both sides of the pipeline within each 2.0m wide and Its insulation material should be non-combustible material. 5. The damper should set up a separate hanger to prevent pipe deformation affecting its performance in case of fire. 6. damper fuse should be installed in a large piece of the side facing the fire risk.
