Abstract:
A fire detection apparatus includes a fire detector (1) including an integrated sounding device (5) that is configured to emit a sound (7) from the fire detector (1) and that is further configured to detect reverberation of the emitted sound resulting from a cover (9) placed over the fire detector (1). The detected reverberation can be used to determine that the fire detector (1) has been covered.
