2.3 remote control type smoke damper (rope-controlled) function as follows: 2.3.1 has a normally closed smoke damper all the features of 2.3.2 remote manual open, manual reset Close .2.3.3 rope control distance standard 6m (long customizable) 2.4 automatic reset type smoke damper functions are as follows: 2.4.1 usually was normally closed, fire dampers price, when the fire broke out, from the control center DC24V power input, the valve automatically opens .2.4 .2 when the pipe temperature reaches 280 ℃, the fuse action, the valve automatically closes .2.4.3 .2.4.4 manually open the valve is turned on, without manual reset, fire dampers principle, as long as the input DC24V power, the valve can be automatically reset to original closed position (this feature is limited to the first temperature sensor is not operating, such as temperature sensors need to be replaced after the operation temperature sensors can still use this feature) .2.4.5 output valve open signal, Tangshan damper, smoke interlock control Fan start-stop technical parameters # operation voltage / current:. DC24V / 0.5A # temperature sensor operating temperature: 70 ℃ # refractory time: 1.5h # Leakage Rate: 290m3 / h · m2 (standard state) # when full drag coefficient : <0.4. FH-Y-1 smoke dampers Material: galvanized steel Features: 1. Usually was always open when the fire smoke (temperature) sensor signal sent by the control center, fire dampers wholesale, 24V DC input, the solenoid is energized actions performed within the organization, the valve automatically closes and the output off signal. After a manual reset valve operation. 2. Valve can also be manually shut down or shut down 70 ℃ action. 3. Control voltage DC24V, micro switch contact capacity of AC380V, 3A, solenoid operating current 0.3A. 4. Control and related equipment interlock. 5. When full drag coefficient f≤0.5. Size: W × H with duct size Description: FH-Y-1 (rectangle) Rui Xincheng air conditioning (Figure) _ _ Tangshan damper flue damper is provided by the Texas Air Conditioning Equipment Co., Ltd.
