4.3 Installing the Unit
The aspirating smoke detector can be installed with the aspiration device pointing upwards or
downwards. Turn the detector module in the cover by 180° as applicable.
Aspiration from above
Ensure that the air outlet of the aspirating smoke detector is not obstructed. Maintain a
distance of at least 10 cm between the air outlet of the FAS-420-TM and the surrounding
objects (e.g. wall).
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 (see Figure 4.2 ).
Turning the detector module in the cover
In order to turn the detector module in the cover of the FAS-420-TM detection unit by 180°,
proceed as follows:
1. Remove the four screws (see Figure 4.3 for positions).
2. Now turn the cover and fasten the detector module again with the four screws.
NOTICE!
It is not permitted to use different operating modes in one loop/stub/T-tap next to each other.
NOTICE!
– When selecting the installation location, ensure that the unit displays are easily visible.
– Remember when planning that the unit fans generate a noise level of approx. 40 dB(A).
– In order to prevent damage to the device, ensure that the installation location is not in a
door opening area.
