A safety device for the air in a room has an intake air channel for supplying outside air to the room. A device for air treatment is provided. A detector for air contaminants is arranged in the intake air channel. A safety closure with a drive is arranged in the air intake channel and has an open position and a closed position for airtightly closing the intake air channel or an inlet of the device for air treatment that is arranged downstream of the safety closure. An exhaust air channel is connected to the room and the device for air treatment. When the safety closure is in the open position, a partial recirculating operation occurs. When the safety closure is in the closed position, a complete recirculating operation is present. The device for air treatment, the detector, and the drive are connected to a control device.

What is claimed is: 1. A safety device for the air in at least one room of a building, the safety device comprising: at least one intake air channel for supplying outside air to the at least one room; at least one exhaust air channel connected to the at least one room; at least one device for air t
What is claimed is: 1. A safety device for the air in at least one room of a building, the safety device comprising: at least one intake air channel for supplying outside air to the at least one room; at least one exhaust air channel connected to the at least one room; at least one device for air treatment comprised of an air treatment device, a first air quality sensor, a second air quality sensor, at least one ionization apparatus, an airflow sensor, an air humidity sensor, and a first ozone sensor; a recirculating air channel connecting the at least one exhaustair channel and the air treatment device; a supply air channel connecting the air treatment device to the at least one room; wherein the first air quality sensor is arranged in the intake air channel or in a supply air channel connected to the air treatment device; wherein the second air quality sensor is arranged in at least one of the at least one room, the at least one exhaust air channel, and the recirculating air channel; wherein the at least one ionization apparatus, the airflow sensor, the air humidity sensor and the first ozone sensor are arranged in the supply air channel; at least one second ozone sensor disposed in at least one of the supply air channel and the recirculating air channel; at least one detector for air contaminants arranged in the intake air channel, wherein the at least one detector for air contaminants converts at least one input signal into an output signal representing a value of one or several parameters; at least one control device, wherein the at least one device for air treatment, the at least one detector for air contaminants, and the at least one second ozone sensor are connected to the at least one control device; a safety flap coupled to a drive, wherein the safety flap is arranged in the air intake channel and wherein the drive is connected to the at least one control device; wherein the safety flap in an open position opens and in a closed position closes airtightly the intake air channel or an entrance of the at least one device for air treatment, wherein the device for air treatment is arranged in a flow direction of the outside air downstream of the safety flap and wherein, when the at least one detector for air contaminants arranged in the intake channel detects air contaminants, the at least one control device actuates the drive and the drive moves the safety flap from the open position into the closed position to automatically shut off flow of outside air to the at least one device for air treatment and decouple the at least one room from the outside air and cause the exhaust air of the at least one room to be recirculated through the recirculating air channel to the at least one device for air treatment and then through the supply air channel to the at least one room so that a total recirculating operation takes place and the exhaust air is treated again; wherein, when the safety flap is in the open position, a partial recirculating operation is present through the recirculating air channel to the at least one device for air treatment and then through the supply air channel to the at least one room; wherein the at least one control device supplies an electrical ionization power to the at least one ionization apparatus which electrical ionization power is adjusted automatically as a function of values of at least one of the first air quality sensor, the airflow sensor, the air humidity sensor, and the second air quality sensor; wherein, when an ozone level of a certain value is measured by the first and the at least one second ozone sensors, the control device reduces the electrical ionization power; wherein, when the ozone level increases further or the certain value remains the same, the control device changes a spacing of alternating pulses, of alternating pulse rates and/or of packages of alternating pulses of the electrical ionization power causing conversion of the ozone to natural oxygen clusters (charged oxygen molecules). 2. The safety device according to claim 1, wherein the at least one detector for air contaminants is a sensor for at least one chemical substance, a sensor for at least one biological organism, a dosemeter, or a device for determining air-borne particles. 3. The safety device according to claim 2, wherein the dosemeter is a luminescence dosemeter. 4. The safety device according to claim 1, further comprising an additional airflow sensor arranged in the intake air channel, wherein the additional airflow sensor is connected to the at least one control device. 5. The safety device according to claim 1, wherein the detector for air contaminants is located in an end area of an intake opening of the intake air channel or in an intake device for outside air arranged in the intake air channel. 6. The safety device according to claim 1, wherein a volume of the intake air channel is configured based on at least one parameter selected from the group consisting of an airflow velocity in the intake air channel, a time delay of the detector for air contaminants, a time delay of the control device, and a time delay of the drive including an inertia of the safety flap. 7. The safety device according to claim 1, wherein the drive is a spring return drive. 8. The safety device according to claim 1, wherein the at least one room has an escape air channel, wherein the escape air channel is closable by a driven flap or valve, and wherein a drive member of the flap or an actuating device of the valve is connected to the control device. 9. The safety device according to claim 1, wherein at least one of the control device and the drive is provided with at least one manually actuatable switch such that the safety flap is closed after actuation of the at least one manually actuatable switch.
