The invention relates to electrical equipment of vehicles and can be used in devices for signaling a change in maneuver and emergency mode.

The purpose of the invention is to increase yn-: formattivity by signaling an emergency mode.

j The drawing shows the functional | on the device diagram.

The vehicle alarm device contains lamps 1 and 2 turn indicators, the power supply of which includes a flash frequency setting unit 3, performed on a series-connected multivibrator 4 and a thyristor switch 5. To the output of the latter, an executive relay 6j of which is connected is connected to the circuit power supply control lamp 7 turn indicators. Opening and closing the lock contacts

14.1 of which are connected in parallel to the alarm switch 15 connected to the power supply circuit of lamps 1 and 2 through the operation mode switch 16.

The device works as follows.

With the corresponding position of the lock 8, the device is in the initial state, which corresponds to the Stand mode. In this case, the output of the trigger 9 is formed by a low level signal.

When the vehicle is moving, the relay 11 is powered by the generator 12, as a result of which the contacts 11.1 are closed. The voltage of the power source through closed contacts 11.1 is fed to the input of the inverter 13n trigger 9, putting the latter into a position where a high voltage signal is generated at its output One; however, the relay 14 does not operate f because the low level signal from the inverter output 13 blocks the element And 10 and at its output a low level signal is generated.

During a sudden stop of the engine, alternator voltage is not present at the output of generator 12, as a result of which contacts 11.1 of relay 11 open. In this case, the trigger 9 retains its steady state, and a high level signal is generated at the output of the inverter 13. High level signal from the output of the element And 10

the relay 14 is energized, the contacts of which 14.1 are closed and the lamps 1 and 2 light up, signaling the emergency mode.
