The ASD filter box FDAZ292 is used in environments with a high dust
concentration, where it protects the aspirating smoke detector from contamination.
The filter box filters dust and dirt particles out of the pipe system before they can
reach the aspirating smoke detector. This increases the service life of the
aspirating smoke detector. The filter box is installed in the pipe system immediately
upstream of the aspirating smoke detector.
The filter box must be taken into account when planning with the 'FXS2056 ASD
Asyst‑Tool V3' software because it causes a pressure drop within the pipe system.
