用途：信号反馈装置安装在集流管或区域出管上，当灭火剂释放时，集流管中压

Uses: signal feedback device is mounted on a manifold or a tube area, when the fire-extinguishing agent release, the collector increases the pressure tube, so that the operation, the feedback signal sent to the control panel, showing the container valve, a selector valve is open, fire agents have been released. Feedback signal means after operation, maintenance and inspection should be, must manually reset only after continued use.

Use: Signal feedback device is installed on the distribution tube or area outlet tube, when the fire extinguishing agent is released, the pressure in the concentrated pipe increases, so that its action, sends a feedback signal to the control panel, indicating that the machine valve, the selection valve has been opened, the fire extinguishing agent has been released. After the signal feedback device action, should be repaired and checked, must be manually reset before continue to use.

Purpose: the signal feedback device is installed on the collecting pipe or the area outlet pipe. When the fire extinguishing agent is released, the pressure in the collecting pipe increases, making it act, sending the feedback signal to the control panel, indicating that the container valve and the selection valve have been opened, and the fire extinguishing agent has been released. After the signal feedback device acts, it shall be maintained and checked, and it can be used only after manual reset.
