Can you electrically control the closing of air vents in different smoke prevention zones? When the fire is confirmed, it shall be able to turn on the smoke outlet and smoke exhaust fan in the smoke exhaust area, and automatically turn off the ventilation and air conditioning system irrelevant to smoke exhaust.

1、多个排烟分区合用排烟排风系统，排烟管道安装的就是电动阀+排烟风口，平时常开排风，着火关闭非着火点排烟分区的设置在支管上的电动阀，超过280度风口熔断关闭，烟气如扩散到其他防烟分区则开启此防烟分区支管上的电动阀。

1. Multiple smoke exhaust zones share the smoke exhaust system. The smoke exhaust pipe is installed with an electric valve + smoke exhaust outlet. Usually, the exhaust is always open, and the electric valve set on the branch pipe of the smoke exhaust zone without ignition point is closed on fire.
