In the emitter io equal voltage to the threshold voltage 1 / _σΜ + Ubb * feed line is arranged, the rectifier GrI, the and the transistor Tl is turned on. So that the collector is on the reference via the resistor RS it is achieved that interference pulses, which are shorter than the on-potential, are carried out. The collector connection is also speech delay, does not lead to a setting of the relay polarized with one connection point of a parallel circuit. Several such pulses from the resistor R6 and the rectifier Gr 3 15 at short intervals are also suppressed because they are connected. The second connection point of the parallel of xl responsible for the charging time constant is Wischaltung is on one side of reference resistor R6 for the discharging by the DC potential lying integrating capacitor Cl and to judge Gr 3 bridged in part to the. Thus, only the other one is effective via the Zener diode Gr 4 to the base of a lent smaller resistor RS , and a second transistor Tl, in whose collector circuit the ao rapid discharge (τ *: xl ** »1: 8) can take place. A winding MI of the polarized relay connected in series, interfering pulses that occur are also carried out. Between the base and the collector of the presses.

The resistance in the base The difference is that the signaling contacts circle is denoted by Rl. Changeover contacts are parallel to the winding MI mkl ... mkl6. In the signaling of the polarized relay, the rectifier GrS is a signaling part 12 is only a lamp for signaling. It is intended to limit the voltage when the A and B alarms are deactivated. The control sub-switches are provided. The circuit 30 separation of the A and B alarm and their separate for the second winding MlI of the polarized relay, optical display takes place in the central signaling of the rectifier Gr 6 flies in parallel, is via the field. Furthermore, the acoustic signaling of the delete button LT can also be closed. The capacitors are done externally by the alarm clock. The associated Cl / 1 .. .Cl / 16 and the rectifiers Gr 1/1 ...
