1, usually normally closed, the control center DC24V electrical, exhaust port open fast. 2, remote manually open. 3, remote manual reset. 4, the output signal is turned on action, interlocking related equipment. 5, plate discharges do not have to open the flue gas after the temperature reached 280 degrees, turn off the function again. Plate discharges, fire protection components, usually installed in the pipe plate discharges offer mechanical exhaust system, usually was turned on near the control plate discharges, when the fire within the flue gas exhaust pipe temperature reaches 280 degrees Close and meet in a certain amount of time leakage of smoke and fire integrity requirements, from smoke fire retardant effect. Main material: carbon steel, galvanized plate discharges price, stainless steel. Plate discharges purposes have the following points: (1) usually in a normally closed valve, either manually or automatically open fire, when the air flow when the temperature reaches 280 ℃ plate discharges, temperature sensors action, the valve is closed; (2 ) allows the valve is closed by DC24V power; (electric type smoke damper) (3) or manual reset manually shut down; (4) after closing DC24V electric reset; (automatic type smoke damper for the inconvenience manually operated local) remote control plate discharges, plate discharges, air conditioning provided by the Texas shenglong Shenglong ventilation and air conditioning plant.
