Example:
If 3 of a total of 8 air sampling openings are found to be obstructed, airflow monitoring must
be set to ± 25% using the FAS‑ASD‑DIAG Diagnostic Software.
Notice!
When planning in accordance with EN 54‑20 or ISO 7240-20, airflow monitoring must always
be set to 20%.

Simplified pipe planning

Simplified planning is used for equipment protection and in premises with smaller
dimensions. The benefit of this type of planning is the standard diameters of the suction
openings.
Planning is to be carried out according to regulations specified in Standard Pipe Planning.
Additionally, the following limiting values and opening diameters must be observed. An
additional accessory (air filter, condensate separator etc.) can have an effect on the maximum
pipe length.
