NOTICE
Bends are to be preferred over angles. An excessive number of changes in
direction can change the detection time.
If the pipe system does not match the project planning guidelines described
here due to structural constraints. WAGNER should offer could provide indi-
vidual calculations for such a case.
Check detection reliability with activation tests in cases where use of the sys-
tem is critical. Also check whether an air flow rate is present at individual as-
piration apertures.
TIP
The fan voltage can be increased in order to reduce transport time. Make
sure that the current intake increases.
Air flow monitoring
EN 54-20 or ISO 7240-20 requires the recognition of a 20 percent change in
the air flow volume by the detector module’s air flow sensor system. The ac-
tivating threshold of the air flow sensor system has to be adjusted to ≤ 20 %
in order to achieve this. It is recommended to conduct an air pressure-
dependent air flow compensation for both of these settings.
Any threshold desired may be set with systems which do not require EN 54-
20 or ISO 7240-20 conformity.
Project planning for the air flow monitoring system in sampling pipes is car-
ried out while taking into consideration the respective national regulations for
each country.
The air flow sensor sensitivity must be adjusted to the application in ques-
tion. Breakage and stoppages must be detected reliability with low suscepti-
bility to malfunction.
The activating threshold and for this reason the sensitivity of the air flow
sensor is continuously adjustable from 10 – 50 %.
