The modification of the smoke detector is based on the fact that an infrared sensor and a receiver for the signals commonly sent by household remote control units and in particular those used for consumer electronics are built into the detector along with the test button, which is standard component in all smoke detectors. The smoke detector reacts to a signal transmitted by the domestic remote control unit and aimed at the detector, making it possible to test that the detector is functioninig correctly without having to press the test button.
