For normally open fire doors, civil buildings are generally flat doors, single door fashion a fire door release switch and a single linkage module, double door fashion two fire door release switches and two single linkage modules.
对于常开的防火门,民用建筑一般是平开门,单扇时装一个防火门释放开关及一个单联动模块,双扇时装二个防火门释放开关及两个单联动模块。

After the smoke probe on either side of the fire door detects the smoke, it reports the smoke to the fire alarm controller through the bus, and the linkage controller issues the action command according to the existing setting. After receiving the command, the single linkage module dedicated to the fire door closes the passive normally open contact of the module, connects the DC, 24V coil loop of the fire door release switch, and the coil is instantly powered up to release the fire door.
防火门任一侧的烟探头探测到烟雾后,通过总线报告给火灾报警控制器,联动控制器按已有设定发出动作指令,防火门专用的单联动模块接收指令后模块的无源常开触头闭合,接通防火门释放开关的DC,24V线圈回路,线圈瞬间通电释放防火门;

The fire door is automatically closed by means of the spring of the door close device, and the DC, 24V coil loop is automatically cut off because the fire door is detached from the release switch. At the same time, the auxiliary contact of the fire door release switch inputs the fire door status signal into the single linkage module, and then sends it to the fire control room through the alarm bus.
防火门借助闭门器弹力自动关闭,DC,24V线圈回路因防火门脱离释放开关而自动被切断,同时,防火门释放开关的辅助触头将防火门状态信号输入单联动模块,再通过报警总线送至消防控制室。

The fire control room can also directly control the linkage module on site through the bus to close the fire door and get the confirmation feedback signal of the fire door closing.
消防控制室也可通过总线直接控制现场的联动模块关闭防火门并得到防火门关闭的确认反馈信号。
