Notice!
When selecting the installation location, ensure that the LEDs 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

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.
