FIELD: protection. SUBSTANCE: analog signal shaper is made in form of two-channel amplifier in which one channel is formed by amplifier and adder, and other channel, by noise signal amplifier with integrator. Inputs of channels are interconnected and connected with output of external action sensor. Output of first channel is connected with input of comparator, and output of second channel is connected with first channel. Comparator is coupled with load control unit. Device operates reliably at shaking, vibrations and under other abnormal conditions. EFFECT: reliable protection of vehicles at any conditions of parking, protection of production objects, offices. 2 dwg
