Изобретение относится к технике охранной сигнализации и может быть использовано для защиты различных объектов от вторжения нарушителя. Задача изобретения - повышение надежности работы устройства. Устройство обеспечивает свое устойчивое функционирование при появлении электрических помех в цепи питания и формирует сигнал тревоги при снижении напряжения питания ниже установленного значения. Это достигается введением делителя напряжения, формирователя порогового напряжения, одновибратора и блока з щиты.The invention relates to techniques for burglar alarms and can be used to protect various objects from intruder intrusion. The objective of the invention is to increase the reliability of the device. The device ensures its stable operation when electrical noise appears in the power circuit and generates an alarm when the supply voltage drops below the set value. This is achieved by introducing a voltage divider, a threshold voltage shaper, a single-shot and a protection unit.
