Because of the limited transmission power, the reception area is limited. Since there are still no constant calls for help, a number of emergency callers can work on the same frequency without causing unreasonable interferences which make it difficult to recognize the individual call for help.
  • the emergency call transmitter advantageously contains several emergency call buttons with which the emergency call identifier corresponding to the situation is selected.

  • emergency call activation is possible wirelessly: the user of the emergency caller can also, e.g. In this case, a wire connection is not required while using the motor vehicle.
  • the emergency buttons are advantageous pull switches that are designed so that when the protective flap is closed, all switches must be returned to the "OFF" position. This prevents that when the emergency call transmitter is closed and thus deactivated, emergency call signals are generated unintentionally, under load on the voltage source.

  • a further development has a receiving part which can receive an acknowledgment signal from the central station.
  • This acknowledgment signal prevents the emergency signal from being emitted as a signal modulated onto the carrier frequency, so that the voltage supply is relieved. This avoids a constant, renewed addressing of the recipient of the central office, which is thereby kept free for further incoming calls for help.
  • a receipt light can be switched on on the emergency call, which informs the caller for help that his call for help has been received and the necessary steps for rescue have been initiated.
  • the carrier frequency continues to be emitted, the directibility of the emergency caller is retained.
  • the transmitter and receiver are advantageously decoupled in that the transmitter works in pulse mode and the receiver is only active during the transmission pauses. After the help arrives, the emergency call generator is then deactivated so that the then unnecessary load on the voltage source is eliminated.
