Definitions

  • the outputs of the timing elements are connected to the inputs of an AND element which controls the alarm and that the window discriminator has two complementary transistors, the emitters and bases of which are connected together and connected via an ohmic resistor which is connected on the base side Connection is via a capacitor to ground, its capacitance and the value of the resistor are dimensioned such that the voltage change at the output of the amplifier caused by the slowest disturbing movement still to be detected is greater than that at the connection point between the capacitor and the resistor.
  • the reference voltage is not rigid, rather it constantly adjusts to the changing output voltage of the amplifier, so that the window discriminator is always driven quasi-symmetrically and the false alarms described are thereby effectively avoided.
  • the adjustment time is selected by appropriate dimensioning of the components so that an optimal compromise between reaching the operating state on the one hand and a safe alarm triggering is achieved even with slowly moving objects (burglars) on the other.
  • a dynamic window discriminator which consists of an npn transistor T and a pnp transistor T 2 , the collectors of which are connected through load resistors R 1 .
  • R 2 is connected to the two poles of the DC operating voltage ⁇ U B , their emitters and their bases are connected directly to one another, they have an ohmic resistance R 3 between the common bases and emitters and on the emitter side via an ohmic resistance R 4 for adjustment the trigger amplitude to the amplifier output, and are connected on the base side via a capacitor C to ground potential.
  • the motion detector described has an extremely low susceptibility to false alarms and is therefore ideally suited for its intended use.
