▪ The airflow sensor was calibrated depending on the air pressure (see
chapter "Air pressure-dependent airflow calibration").
▪ No large airflow fluctuations can occur.
Air pressure differences
The same air pressure must be present throughout the aspiration pipe.
5.1.4 Sensitivity
The sensitivity of a TITANUS PRO·SENS® can be classified into specific fire
sensitivity classes according to AS ISO 7240-20. These fire sensitivity
classes describe specific example applications in which the systems can be
used. Permissible system project planning can be determined for each
classification according to the chapter "Pipe project planning".
Aspirating smoke detectors with a higher fire sensitivity according to
AS ISO 7240-20 also meet the requirements of the lower classes.
Class Description Application example
A Aspirating smoke detector
with very high sensitivity
Very early detection:
Heavy smoke dilution via air
conditioning in IT areas
B Aspirating smoke detector
with increased sensitivity
Early detection:
Saves a great deal of time with
very early fire detection (without air
conditioning)
C Aspirating smoke detector
with standard sensitivity
Normal detection:
Fire detection with the advantages
of aspirating smoke detectors
If the aspirating smoke detector and pipe system are located in areas with
different air pressure, return of the air drawn in by the
TITANUS PRO·SENS® into the pipe system pressure area must be
planned (see chapter "Air return").
NOTICE
Depending on the number of aspiration apertures, the fire sensitivity classes
A, B and C can be achieved with each available detection module.
