Abstract (en)
[origin: EP1475761A1] A device for visual inspection of a smoke detector positioned in an aircraft, and preferably located in the air extraction duct of an aircraft toilette, the smoke detector being functionally restricted by obstacles such as coverings, moldings etc at its entrance aperture or at a protective grating. At least two air-pressure sensors (1-3) are positioned in the vicinity of the smoke detector (7) which detect air-pressure differences occurring on the basis of a cover of the smoke detector (7) and/or of the protective grating (6), and an evaluating- and display-device is subordinated to the air-pressure sensors for determining and displaying the obstacles restricting the functioning of the smoke detector (7).
