Danger alarm device for a vehicle, particularly for a guided lift truck, having at least one sensor which detects the appearance of an object or of a person in a specific area, e.g. in front of or behind the vehicle, and generates a corresponding alarm signal. A clock generator (3) generates a continuous pulse signal which is connected on the one hand directly to an input of a flip-flop circuit (6) and on the other hand via the sensor (M) to another input of the flip-flop circuit (6). In the case of signal coincidence, the flip-flop circuit (6) generates a corresponding pulse chain which is amplified and rectified. <IMAGE> |
