產品描述

Remote control multi leaf smoke exhaust port (multi leaf smoke exhaust ports are generally installed in corridors or smoke control front rooms and are usually closed. When a fire occurs, the smoke detector sends a fire alarm signal, and the control center connects an electrical signal to the solenoid on the valve to quickly open the valve. Alternatively, the valve can be manually opened for smoke exhaust)
