with active location of the fire must be installed
outside the areas to be monitored and without air return.
NOTICE
ROOM·IDENT cannot be used in applications with varying or not consistent
air pressure levels. This is due to the fact, that under these conditions the
aspirated air needs to be returned to the monitored area. Since air return is
not allowed with ROOM·IDENT these applications cannot be served.
Sensitivity
According to EN 54-20 or ISO 7240-20, the sensitivity of a air sampling
smoke detection system can be divided into particular fire sensitivity classes.
These sensitivity classes describe particular example applications in which
the systems can be used. Permissible system project planning can be de-
termined for each classification according to Chapter 5.2.
Air sampling smoke detection systems with a higher sensitivity class accord-
ing to EN 54-20 or ISO 7240-20 also meet the requirements of the lower
classes.
Class Description Example application
A
Air sampling smoke
detector with very high
sensitivity
Very early detection:
Highly diluted smoke in air
conditioned IT areas
IT areas
B
Air sampling smoke
detector with increased
sensitivity
Early detection:
Diluted smoke
in conventional
(cooled IT areas)
C
Air sampling smoker
detector with standard
sensitivity
Standard detection:
Fire detection with
the benefits of air
sampling smoke detection systems
NOTICE
The fire sensitivity classes A, B and C can be achieved with each detector
module available, depending on the number of aspiration apertures.
