Aspiration from below
If the air-return pipe is directed upwards, it must be guaranteed that no foreign bodies or
dripping water can penetrate the air return. You should therefore use a short, downward
angled pipe.
Mounting type MT-1
The aspirating smoke detector is either bolted directly to the wall provided for installation
using the rear panel or installed by means of unit mounting type MT-1, e.g. onto frames.
