ASD 532

Design and function

ASD 532 – Powerful and compact

The ASD 532 is used for reliable monitoring of small and medium-sized areas and premises. It has the same technical specifications as the ASD 535, but with just one sampling pipe and a more compact fan. Anyone familiar with the ASD 535 will find added monitoring using the ASD 532 a breeze. Configuration and maintenance of the detector are made in the same simple way.

Aesthetically, the ASD 532 is very subtle and discreet – just like all devices in the ASD range. Once installed in hollow spaces, the sampling pipes are completely invisible, while the flush-mounted sampling holes are often imperceptible.

The installation is carried out with the highest possible level of adaptation to the surroundings in question. The sampling pipe can be laid out asymmetrically, which means it blends seamlessly into the structure of the building. This eliminates the need for long sampling pipes and thus reduces costs.
