According to a first aspect of the invention, the object is achieved by a method for monitoring a triggering operation of a door by a monitoring device, wherein the door has at least one door leaf, a door operator and a locking device, and further wherein the at least one door leaf by the locking device in a first Door position is locked and released in a release of the locking device for a driven by the door operator movement in a second door position. A method according to the invention is characterized by the following steps:

1. a) monitoring the locking device by a trigger sensor element of the monitoring device,
2. b) detecting a release of the locking device by the trigger sensor element,
3. c) starting a monitoring period by a monitoring unit of the monitoring device after detecting the triggering in step b),
4. d) checking that the at least one door leaf reaches the second door position through a door sensor element of the monitoring device during the monitoring period started in step c), and
5. e) in the event of a negative result of the check carried out in step d) output of an alarm signal by an alarm unit of the monitoring device.

An inventive method is provided for use in a door with at least one door leaf. Furthermore, a door, in which a method according to the invention is to be used, has a locking device and a door operator. By means of the locking device, the at least one door leaf can be locked in a first door position and, when the locking device is triggered by the door operator, automatically moved into a second door position. For the first door position, both an open position and a closed position of the door leaf, for the second door position, conversely, a closing position and an open position are conceivable. A door, in which a method according to the invention can be carried out, can thus be realized, for example, as a fire door, which is to be closed when the locking device is triggered, or as an escape door, which is to be opened when the locking device is triggered. By a method according to the invention it is now provided that a scheduled execution of this automatic and driven by the door operator movement is carried out safely after triggering of the locking device and in particular an erroneous performing, d. H. not completely closing or opening the door, is reliably detected.

For this purpose, in a first step a) a monitoring of the locking device is performed. For this monitoring, the monitoring device, which is designed in particular for carrying out a method according to the invention, has a triggering sensor element. The monitoring in step a) of a method according to the invention can preferably be carried out continuously or at least substantially continuously. In this way, particularly in the next step b) of a method according to the invention, a triggering of the locking device by the triggering sensor element can be detected. As described above, this release of the locking device is accompanied by a beginning of the movement of the at least one door leaf driven by the door operator. In order to map this movement duration of the movement of the door leaf from its first door position into its second door position, a monitoring period is started in a method according to the invention in the next step c). This starting can also be carried out in a control unit of the monitoring device, wherein this control unit is designed, for example, as a computer unit. During the monitoring period started in step c), in step d) of a method according to the invention a door sensor element of the monitoring device checks whether the second door position is reached by the at least one door leaf. During the monitoring period, in the sense of the invention, it can mean, in particular, that time-by-time checks in the course of the monitoring period repeatedly check whether the at least one door leaf has already reached its second door position. A continuous or at least substantially continuous continuous checking of reaching the second door position by the door during the monitoring period can be carried out in step d) of a method according to the invention. A single measurement for checking an event of the second door position by the at least one door leaf at the end of the monitoring period started in step c) is to be understood in the context of the invention by the term 'during the monitoring period'. In particular, the monitoring period does not end before the last monitoring or measurement for checking the event of the second door position has been carried out by the at least one door leaf. In the last step e), if in step d) the checking of the event of the second door position by the at least one door leaf has produced a negative result, an alarm signal is output. This alarm signal is issued in particular by an alarm unit of the monitoring device. A negative result in the sense of the invention means in particular that during the entire monitoring period in step d) no reaching of the second door position by the at least one door leaf could be determined. In this case it is assumed that the movement of the at least one door leaf driven by the door operator could not be carried out properly. By issuing an alarm signal, it is now possible to inform a direct environment of the door about this error state of the door. By means of appropriate signal connections, cable-based or wireless information can also be sent to remote locations via this malfunction. A security when operating doors with locking devices and door actuators can be increased in this way.

Furthermore, it can be provided in a method according to the invention that in step b) by a detection of a trigger signal to the locking device and / or by detecting an activation of the locking device, a release of the locking device is detected by the trigger sensor element. In this way it can be provided that the triggering of the locking device is detected in various possible ways by the triggering sensor element. For example, it can be provided that the triggering sensor element is designed for direct tapping of a triggering signal, for example provided by a smoke detector, whereby a downstream triggering of the locking device can be detected at least indirectly. Direct observation of the locking device can alternatively or additionally be performed by the trigger sensor element. Thus, for example, in the presence of an electromagnet in the locking device, an energization or an end of a current supply thereof can be determined by the triggering sensor element and in this way a triggering of the locking device can be detected. Overall, therefore, a particularly flexible detection of a release of the locking device can be provided by these different possibilities, which is particularly well adapted to a wide variety of requirements.

Also, a method according to the invention can be designed such that a duration of the checking period started in step c) is selected as a function of a movement duration of the at least one door leaf from the first door position to the second door position, in particular that the checking period is at least approximately 50% longer is as the duration of movement, preferably about 100% longer than the duration of movement. According to the invention, the duration of movement is understood to mean, in particular, that time which the door leaf requires in the door movement driven by the door operator from its first door position to its second door position, if this movement can be carried out without hindrance and properly. By a selection of a duration of the checking period adapted to this duration of movement, a particularly good adaptation of a method according to the invention to the door to be monitored can be provided. By choosing the duration of the checking period at least about 50% longer, preferably about 100% longer than this duration of movement can be provided in particular that only a short-term blocking the movement of the at least one door from its first door position to its second door position not yet Error is detected. In particular, it can be provided in this way that only longer-lasting, in particular continuous, blockages of the movement of the door leaf are recognized as errors. Thus, for example, only a brief holding open a fire door for letting people are allowed without immediately an alarm when performing a method according to the invention is issued.

Alternatively, it can be provided in a method according to the invention that a duration of the test period started in step c) is selected between about 10 seconds and about 60 seconds, in particular 20 seconds. By such a choice of an absolute duration of the review period, a particularly simple selection of a duration of the review period can be provided. In particular, with a duration of between about 10 seconds and about 60 seconds, preferably with a duration of 20 seconds, the method can be made suitable for a large number of doors. As in the case of a selection of a duration of the monitoring period relative to a movement duration, even if a choice of absolute duration is selected, only longer-lasting, in particular continuous, blockades of movement of the at least one door leaf are recognized as errors.

The two above-mentioned variants of the choice of a duration of the checking period can also be used in addition to one another, wherein, for example, by choosing the respective longer variant, a particularly reliable detection of an incorrectly performed movement of the at least one door leaf can be provided by a choice of the shorter variant a particularly rapid alarm can be provided with a blocked movement of the at least one door leaf.
