What is claimed is: 1. An alarm in a device for dispensing volatile anesthetics, the alarm comprising: an alarm element; an operating voltage supply; an assembly unit that determines the dispensing of at least one anesthetic, said assembly unit having a prescribed state of operation or operation position; and an alarm triggering means for triggering the alarm element whenever the operating voltage is interrupted and said assembly unit is not in said prescribed state of operation or operation position. 2. A device in accordance with claim 1, wherein said assembly unit that determines the dispensing of at least one anesthetic comprises an electronically driven valve assembly unit. 3. A device in accordance with claim 2, further comprising a buffer voltage source wherein said assembly unit that determines the dispensing of at least one anesthetic comprises an actuation element or handwheel for changing a setting of said electronically driven valve assembly unit and said triggering means comprises at least one switch actuated by said actuation element or handwheel, said switch being in an open state when said actuation element or handwheel is in a position in which no alarm is to be triggered, and said switch is in a closed state when said actuation element or handwheel is in a position in which an alarm is to be triggered, said switch being integrated within a current path that connects said triggering means with the output voltage of said buffer voltage source only when the operating voltage from said operating voltage supply is interrupted. 4. A device in accordance with claim 3, wherein a microcontroller is present, which can trigger a current path for the supply of the alarm-generating component if the supply voltage is present. 5. A device in accordance with claim 3, wherein said buffer voltage source is a rechargeable battery. 6. A device in accordance with claim 3, wherein said triggering means includes a switching circuit, which is actuated by said actuation element or handwheel. 7. A device in accordance with claim 1, wherein said assembly unit that determines the dispensing of at least one anesthetic comprises a mechanism with variable flow cross section, whose flow cross section can be set by means of a handwheel. 8. A device in accordance with claim 7, wherein the prescribed state of operation, in which no alarm is triggered in case of interruption of the operating voltage, is the closed state of the mechanism with variable cross section, in which the handwheel is in a zero position. 9. A device in accordance with claim 7, wherein the prescribed state of operation, in which no alarm is triggered in case of interruption of the operating voltage, is a state of the mechanism with variable flow cross section, in which the flow cross section is below a threshold value. 10. A device in accordance with claim 1, wherein said triggering means comprises a switch to indicate the prescribed state of operation or operation position and a current path providing a current flowing from a battery to means associated said alarm element for actuating the alarm element when the switch indicates a state other than said prescribed state of operation or operation position and the absence of an operating voltage from said operating voltage supply. 11. A device for dispensing volatile anesthetics, the device comprising: an assembly unit that determines the dispensing of at least one anesthetic, said assembly unit having a prescribed state of operation or operation position; an operating voltage supply supplying a network voltage to the device; an alarm system with an alarm element and an alarm triggering means for triggering the alarm element whenever the operating voltage is interrupted and said assembly unit is not in said prescribed state of operation or operation position. 12. A device in accordance with claim 11, wherein said assembly unit comprises an electronically driven valve assembly unit. 13. A device in accordance with claim 12, further comprising a buffer voltage source wherein said assembly unit that determines the dispensing of at least one anesthetic comprises an actuation element or handwheel for changing a setting of said electronically driven valve assembly unit and said triggering means comprises at least one switch actuated by said actuation element or handwheel, said switch being in an open state when said actuation element or handwheel is in a position in which no alarm is to be triggered, and said switch is in a closed state when said actuation element or handwheel is in a position in which an alarm is to be triggered, said switch being integrated within a current path that connects said triggering means with the output voltage of said buffer voltage source only when the operating voltage from said operating voltage supply is interrupted. 14. A device in accordance with claim 13, wherein a microcontroller is present, which can trigger a current path for the supply of the alarm-generating component if the supply voltage is present. 15. A device in accordance with claim 13, wherein said buffer voltage source is a rechargeable battery. 16. A device in accordance with claim 13, wherein said triggering means includes a switch switching circuit, which is actuated by said actuation element or handwheel. 17. A device in accordance with claim 11, wherein said assembly unit comprises a mechanism with variable flow cross section, whose flow cross section can be set by means of a handwheel. 18. A device in accordance with claim 17, wherein the prescribed state of operation, in which no alarm is triggered in case of interruption of the operating voltage, is the closed state of the mechanism with variable cross section, in which the handwheel is in a zero position. 19. A device in accordance with claim 17, wherein the prescribed state of operation, in which no alarm is triggered in case of interruption of the operating voltage, is a state of the mechanism with variable flow cross section, in which the flow cross section is below a threshold value. 20. A device in accordance with claim 11, wherein said triggering means comprises a circuit with at least one current path with a switching element.
