Flow alarm on a single room


When your system indicates a flow alarm, this means that the air flow of the air drawn in is not correct during measurement.

During measurement and calibration, the air flow should be approximately 1 liter per minute. When the air flow is much too low, the system will indicate a flow alarm. The air flow can be read on the flow meter on the front of your measuring cabinet.

Watch the video to see step-by-step how to solve the alarm.

If you still have questions after watching the video or if you cannot solve the problem yourself using these instructions, please contact your installer.

1) Take a measurement on the cell indicating a flow alarm

2) Disconnect the hose that is connected to the cell where the measurement is carried out, this can be found on the side of the measuring cabinet

3) Feel at the connection on the cabinet if there is suction.

If it concerns 1 cell, the problem will in most cases be outside the measuring cabinet. It may be that the filter at the end of the hose that is connected to the relevant cell must be replaced. It is also possible that the hose is double or clamped somewhere and therefore causes an alarm. In this video we demonstrate where to find the filter and how to replace it.



  • We always recommend that you have a personal oxygen meter with you when you are working in a CA room.
