- the present invention relates in particular to a drive device for a
- Fire dampers are installed in buildings to prevent fire and smoke transmission in ventilation ducts, for example in walls and ceilings between building sections.
- the fire damper In the function of a smoke and fire barrier, the fire damper is normally open in the normal position to allow the air passage in the ventilation duct, and closed in the safety position in case of fire to prevent the transmission of fire and smoke through the ventilation duct.
- a fire damper it is also possible to configure a fire damper as a smoke extraction damper, which is open in case of fire in the safety position to allow smoke extraction through the ventilation duct, but is normally closed in normal operation.
- the fire dampers are automatically brought into the safety position by a thermal release.
- the thermal release comprises a fusible link which melts at a predetermined melting temperature, for example at 72 ° C, thereby acting as a thermal breaker interrupting a circuit.
- a fire damper with electric drive and spring return interrupts the thermal Breaker the power supply to the drive, so that the fire damper is automatically moved by the spring return in the absence of power to the drive in case of fire mechanically from the normal position to the safety position.
- Fire dampers with thermal breakers have the disadvantage that they react relatively sluggish and therefore often insufficient or even prevent a spread of smoke in the building.
- thermal breaker Breakers have the further disadvantage that they are completely unsuitable for heat test, which are performed, for example, periodically and automatically.
- BE 1 001 873 describes a flap with a gas or smoke sensor.
- No. 5,728,001 describes a flap with a plurality of sensors, each of which can individually trigger the closing of the flap by interrupting the power supply.

This means that the measured value of the content of combustion gases is changed depending on the measured air temperature value and the power supply is interrupted depending on this changed value of the content of combustion gases.
- the switch module is set up to determine a gas limit value depending on the air temperature value, and to interrupt the power supply at a content of combustion gases above this gas limit value. That is, depending on the measured air temperature value, a numerical limit value for combustion gases is defined and the power supply is interrupted if the measured content of combustion gases is above this limit value.
- the switch module is configured to interrupt the power supply at a lying within a defined temperature range air temperature value depending on a defined function of air temperature value and content of combustion gases. In this case, for a break at a temperature value in a lower part of the temperature range, a higher content of combustion gases is assumed than comparatively for a higher temperature value in an upper part of the temperature range.
- the switch module will not trip. This prevents the sole presence of fumes, such as outgassing of items such as packaging material, furniture or carpets, can not cause interruption when there is no fire and thus no heat.
- the switch module triggers an interruption when the air temperature value is higher than an upper range limit of the temperature range. This ensures that the fire damper is felt in the safety position when the fire, while developing heat, does not produce any fumes.
- the interruption is triggered in the variant with thermal break at the melting temperature of the melt slot.
