When selecting the installation location, it must be ensured that the unit displays are
easily visible.
Remember when planning that the unit fans generate a noise level of approx. 40 dB(A).
The air outlet on the unit must not be obstructed. The distance between the air outlet
and adjacent objects, e.g. a wall, has to be at least 10 cm.
The aspirating smoke detector can be installed with the suction device upwards or
downwards (to do this, the detection unit cover must be rotated through 180°). If the
aspiration pipe points downwards, make sure no impurities enter the air-return pipe
which then points upwards.
