Fire Safety
The ASD filter box FDAZ292 is used in environments with high dust concentration.
Installed in the pipe system upstream of the aspirating smoke detectors FDA241
and FDA221; it protects the aspirating smoke detectors against contamination.
The ASD filter box filters dust and dirt particles out of the pipe system before they
get into the aspirating smoke detectors, thereby increasing the service life of the
aspirating smoke detectors.
Installation site requirements
The distance of 500 mm between the aspirating smoke detectors and the ASD filter
box creates a laminar flow inside the detector. This has a positive effect on smoke
detection. This distance can be reduced if space is restricted.
