Remote control plate discharges need remote control fire dampers, remote manual open, DC24V open telecommunications, remote manual reset, the feedback signal or interlocking signal open damper unit, no temperature sensitive damper picture, with 6m rope. Near the control plate discharges contrast, close to manually open, DC24V electrical open, close the manual reset, the feedback opening signal or interlocking signal, no temperature-sensitive plate discharges purposes: usually installed in the elevator, corridor, no exhaust port at the window of the room on the exhaust system, the upper surface of the stick side wall or ceiling surface. Usually in a normally closed state, open for smoke in case of fire. Operating device mounted near the exhaust port from the high walls of about 200mm ground by rope operating device associated with the exhaust port for remote control, the length of the rope is generally 6m. FH-KVD1 fire control valve features: 70 ℃ fuse action, the valve automatically closes. Manually shut down. Output off signal, the interlock related ventilation equipment. Manually open. Manual adjustment of the valve opening angle. Exhaust valve installed in the exhaust system pipeline, usually generally was closed when the fire manual or electric opening, from the smoke effect. When the internal temperature of the flue gas exhaust pipe 280 ℃ closed within a certain period of time to meet the fire resistance stability and fire integrity requirements duct dampers, from the exhaust valve effect. Smoke damper normally closed (NC, telecommunications numbers turned 280 degrees blown off, or manually turned off) generally used in exhaust systems, exhaust fan can be installed at the inlet of a controlled open by the consumer when the fire control room, the chain is closed also closed the exhaust fan. Exhaust valves, with the three, each unit different names, some based on its operating temperature is called the exhaust valves, and some based on its use of nature called the damper, but just ordinary damper device side fuse metal exchange a fuse 280 degrees that a .3 automatic smoke damper (Metro Engineering) Fire subway ventilation and air conditioning systems, exhaust valve having automatic fire alarm equipment and gas extinguishing system linkage control functions. Each automatic smoke dampers with two independent electric control signal, respectively, by EMCS, gas consumption system to monitor, control signals are DC24V ± 10% signal. Each automatic smoke dampers have six independent feedback signal (three open place, three off place) feedback signals are normally open dry contact signal. Damper units, Rui Xincheng air conditioning (certified), Wuzhong damper is provided by the Texas Air Conditioning Equipment Co., Ltd. Rui Xincheng. Rui Xincheng Texas Air Conditioning Equipment Co.
