TIP
It is recommended to always select the greatest possible level which is
permissible according to national standards.
The device’s air flow monitoring enables the system to detect both pipe
breakages outside the device and sudden obstruction in individual aspiration
apertures (e.g. in the event of sabotage to the pipe system). As the dynamic
air flow sensors are only active if level I has been selected for the air flow
monitoring, the aspects described under “Level I limitation” should be taken
into account here.
The air flow monitoring may only be set to level I if:
▪ Project planning according to “Individual aperture monitoring” has been
carried out (see Chap. “Pipe project planning individual aperture monitor-
ing”),
▪ the air flow sensor has been compensated depending on the air pres-
sure (see Chap. Commissioning “Air pressure dependent air flow com-
pensation") and
▪ No large air flow fluctuations occur.
The same air pressure must be present throughout the sampling pipe.
NOTICE
If the air sampling smoke detection system and pipe system are in areas
with different air pressure, the air sampled by the TITANUS
®
should be re-
circulated in the pipe system pressure area (see Chapter “Air recircula-
tion”).
