Air return for pressurised and dusty areas
Fig.2.16: Principle of air return with
TITANUS
PRO·SENS
®
If the air sampling smoke detection system TITANUS
PRO · SENS
®
and the
pipe system are installed in two areas P1 and P2 with different air pressures,
the air is to be returned to the pressure area of the pipe system (refer to Fig.
2.16). The air return can be used for a pressure compensation or in order to
keep the air clean (e.g. from odours) in neigh boring rooms.

The return air pipe system is connected directly through the protection grid to
the air outlet channel inside TITANUS
PRO·SENS
®
(refer to Fig. 2.17). For
doing so, the pre-punched opening in the protection grid must be broken out.
