Abstract (en)
The device (1) has a housing (2) and a self-testing unit (4) for testing permeability of smoke entrance openings (3) in the housing. A sensor is provided for optically and/or acoustically sensing the opening, where the sensor is a distance sensor (9) and/or light sensor (5). The sensor is arranged in such a manner that a space is formed from the opening up to a fire detection sensor inside the fire alarm device. A reference sensor (8) is provided for measuring an ambient light of the fire alarm device. An independent claim is also included for a method for testing a functional capability of the fire alarm device.
