◆材质：镀锌钢板

◆规格尺寸：W*H配合风管尺寸

◆特性：

1.平时呈常闭状态，火灾时烟感器通过控制中心发来电气信号（DC24V），执行机构内的电磁铁通电动作，阀门自动开启并输出开启信号，阀门动作后手动复位。

2.阀门也可手动开启。

3.能与相关设备联锁控制。

◆Material: galvanized steel

◆Size: W*H with duct size

◆Characteristic:

1. Normally in the normally closed state, the smoke sensor sends an electrical signal (DC24V) through the control center during the fire. The electromagnet in the actuator energizes, the valve automatically opens and outputs the open signal, and the valve is manually reset after the action.

2. The valve can also be opened manually.

3. Can interlock control with related equipment.
