Description

alarm device

The present invention relates to an alarm device for a burglar alarm system.

Intruder alarm systems are used to secure a surveillance zone, such as a site and / or one or more buildings, by monitoring previously defined areas for irregularities that may indicate an intrusion; determine whether an alarm event has occurred by detecting any irregularities; and signal the alarm event if necessary. Burglar alarm systems typically comprise different components and are modular in this respect.

For detection of irregularities, components of the burglar alarm system may include detection devices for detecting a movement; a shock; a closing state of a window, a door, a gate or the like; of image data; the temperature; the humidity; of breakage; of smoke; or other conditions and occurrences in the monitored area. The detection devices can monitor various, not necessarily contiguous, parts of the surveillance zone (secured overall by the intruder alarm system). Depending on a respective detected irregularity, a corresponding determination signal can then be generated and output to an alarm center of the burglary alarm system. In order to determine whether an alarm event is present, detection signals of a number of detection devices can be taken into account jointly by the alarm center in accordance with evaluation logic, for example defined trigger rules or dynamic heuristics. In this case, detection signals of the same type (eg, multiple motion detection signals) and / or different types (eg, a motion detection signal and a vibration detection signal) may be combined. In addition, if the portions of the surveillance zone monitored by several detection devices overlap, redundancies can be created which can contribute to avoiding incorrect classification and thus to increasing the reliability of the burglar alarm system.

After detection of an alarm event, the alarm event can be transmitted, for example, via suitable, possibly normalized, interfaces and protocols, e.g. be transferred to an external service point of a service provider or to a security authority. Alternatively or additionally, the alarm event may be local, i. in the area of the burglary alarm system, in particular directly within the monitored area, be signaled as an alarm signal to warn people on site, to widely indicate the presence of the alarm event, to identify the location of the alarm event and / or burglars or other intruder into the monitored area intruders to discourage or distribute.

Such an alarm signal may in particular be an audible alarm signal, which may be generated, for example, by a siren. Alternatively or additionally, optical alarm signals from a lighting device, such as a signal light, are output. These alarm signals may be particularly suitable for alerting with regard to their sound or their light. For example, acoustic alarm signals should have a particularly high volume and / or a shrill, widely audible frequency; They may also have a temporal change in the volume (cancellation). len, pulse sequence) and / or the frequency (in the manner of a Tongehgehorns) have. Optical alarm signals may have a specific color and / or a particularly high intensity; Moreover, they can be conspicuous by means of light flashes or other pulse sequences and / or a changing emission direction (eg rotating in the manner of a beacon) in a special way. Both norms and / or legal regulations can be taken into account for audible and visual alarm signals.

Alarm devices that function as optical beacons for emitting an optical alarm signal are particularly attached to a building wall of a monitored building or building within a monitored area so that the alarm signal can be widely visible and an alarm event displayed in this manner over a certain distance can. The lighting device of such an alarm device is usually designed exclusively for generating the optical alarm signal and optimized thereon. In this respect, the lighting device has only a single light state, in which they can be added.

It is an object of the invention to provide an alarm device with extended functionality.

The object is achieved by an alarm device with the features of claim 1. The alarm device in this case comprises a signal input for receiving a control signal from an alarm center of the burglar alarm system and a lighting device which can be brought in response to the received control signal in a primary luminescent state with a first color or a secondary luminescence state with a second color of the first color is different. Whether the lighting device the primary light state, the secondary light state or also none of these lighting conditions einninnnnt depends, so from the respective received control signal.

In this case, a state of the lighting device in which the lighting device emits light is regarded as a lighting state. In each case, the respective lighting state is characterized by the color of each emitted light; however, it may additionally be characterized by other characteristics, such as brightness, emission direction, timing (e.g., pulsating, flashing), and duration (e.g., single pulse duration or number of bursts of pulses or flashes) of the emission of the light. If the lighting device does not assume any of the aforementioned lighting conditions, the lighting device preferably does not emit any light.

The primary illumination state and the secondary illumination state differ at least in terms of their color. By color is meant the specific spectral composition of each emitted light. In this respect, in connection with the invention, white is also to be regarded as color. In particular, the primary illumination state does not have the second color and the secondary illumination state does not have the first color. The two lighting conditions may differ in some other way in addition to the color, e.g. in terms of the duration of illumination, the intensity of the light, the direction of illumination or the frequency of an intermittent lighting operation.

In this case, the primary illumination state comprises an optical alarm signal which corresponds to an alarm event in the surveillance zone. In this respect, the primary illumination state can at least be similar to the (single) illumination state of conventional signal lights for burglar alarm systems. Since the optical alarm signal is emitted in the primary light state, it has light of the first color. In particular, therefore, it can already be determined by an observer on the basis of the color that it is the case of the lighting device of the alarm device emitted light is an alarm signal and thus that there is an alarm event in the surveillance zone.

Unlike the conventional signal lights for burglar alarm systems, however, the lighting device of the alarm device can not only assume a single lighting state, but in addition to the primary lighting state, also the secondary lighting state. For this purpose, the lighting device is adapted to emit light in at least one other color, namely in said, different from the first color second color. In this way, the light emitted in the secondary illumination state can be clearly differentiated from an alarm signal emitted in the primary illumination state. This makes it possible to use the alarm device for the optical transmission of alternative or supplementary information or to illuminate a spatial area. In principle, the lighting device can be designed to occupy the primary and secondary illumination states simultaneously and thus at the same time emit both first color and second color light, for example, in the event of an alarm event parallel to the transmission of the optical alarm signal for complementary purposes - to send out a color. Such a supplementary purpose may be, for example, that during an alarm displayed by the visual alarm signal by means of the secondary light state is additionally indicated that the alarm event has been communicated to an external service point of a service provider or to a security authority and / or that to check the alarm Security forces on the way to the surveillance zone.

However, the lighting device can also be restricted to be able to assume the primary lighting state and the secondary lighting state only as an alternative to each other, but not at the same time. The termination of a respective luminous state can be possible, for example, by means of a corresponding further control signal and / or can take place automatically after a period of time has elapsed that can be of different lengths for different luminous states. At least the primary illumination state can preferably be terminated exclusively by means of a control signal.

Furthermore, it is possible that a plurality of primary light states and / or a plurality of secondary light states are provided, in which the lighting device can be brought. The different primary luminous states can in particular all have the same (first) color, while the different secondary luminous states have a different color. With regard to other characteristics of the respective emitted light, the different primary illumination states with each other and / or the different secondary illumination states may differ from each other.

In addition, it can be provided that the lighting device still further

Luminous states with another or more other colors can take. For example, a secondary illumination state in the second color may be an optical information transfer, and a tertiary illumination state may be a third color illumination of a spatial region.

Whether the lighting device assumes a lighting state and optionally which it occupies depends in particular on a respective control signal received via the signal input. The control signal, to which the light device responds, may be suitable for selectively switching the light device to the primary or secondary illumination state. However, it is also possible to provide separate control signals for the primary illumination state and the secondary illumination state. Via a respective control signal, the lighting device can therefore be brought from the outside into the different lighting states. The signal input can be designed for a wired or a radio-based receiving the control signal. The signal input thus forms optionally with further signal inputs and / or one or more signal outputs of the alarm device a respective signal interface for the communication with other components of the burglary alarm system, in particular with the said alarm center.

The control of the lighting device by means of the control signal is advantageously carried out via the alarm center of the burglar alarm system. The alarm center may be, for example, a central unit of the burglar alarm system, e.g. is installed within a respective building to be secured and with which several, in particular all other components of the burglar alarm system can be connected in terms of communication, so that e.g. the burglary alarm system can be activated or deactivated via the alarm center and / or the evaluation of received detection signals by the alarm center takes place. In particular, the alarm center can thus converge a multitude of information, in particular all essential information, about irregularities in the monitoring zone detected by the burglary alarm system and about operating states of the burglary alarm system.

The alarm center is designed, for example, to determine whether there is an alarm event by means of various detection signals, which are generated, for example, by detection devices of the intrusion alarm system as a function of detected irregularities and output to the alarm control center. In particular, in the event of an alarm event, the alarm center can then set the lighting device to the primary lighting state by means of the control signal. A function of the alarm center may also be to receive commands from a user of the burglar alarm system, which may be directed, for example, to activate or deactivate the burglar alarm system, to change a setting of the burglar alarm system or to request information. Such commands can also lead to the generation and emission of a corresponding control signal to the lighting device of the alarm device, wherein the lighting device is preferably offset by such triggered by the user control signal in the secondary light condition. A control signal that puts the lighting device in the secondary lighting state, but does not necessarily have to be triggered by the user. For example, a secondary illumination state can also be taken automatically at specific times or at certain intervals, for example to indicate an operating state of the burglar alarm system by a brief, regular lighting up. When the secondary illumination state is for illumination, the times and intervals, at least within a given frame, may also be random, such as to simulate presence.

Advantageously, the alarm device has a siren for generating an audible alarm signal. A detected alarm event can then be signaled not only visually by the lighting device in the primary light condition, but at the same time also acoustically.

In particular, the siren may be adapted to generate the audible alarm signal in response to the received control signal. In other words, the same control signal can serve, on the one hand, to control the lighting device, in particular to bring it into the primary lighting state, and, on the other hand, to activate the siren to generate the acoustic alarm signal. In principle, the primary illumination state of the lighting device and the generation the audible alarm signal but also be independently triggered and / or terminated.

Preferably, the alarm device further comprises a mounting portion for fixing the alarm device to a building wall. Thus, the attachment of the alarm device to the building wall usually allows mounting in a position (in particular at a comparatively high level, for example of at least about 4 m), especially for the emission of optical and / or audible alarm signals with a view to a wide visibility suitable is. In addition, the alarm device, when attached to the building wall of a building monitored by the burglar alarm system, may act as a deterrent to intruders, for example by its mere presence, by signaling to the outside that the building is being monitored. The attachment portion may in particular have a vertical extent, due to which the alarm device can be stably fixed against tilting in the vertical direction down to the respective building wall. By the attachment portion may be defined a position of use of the alarm device, in which the alarm device is typically attached to a building wall. The attachment portion may be provided on a rear wall of the alarm device.

According to one embodiment, the secondary illumination state of the lighting device comprises an optical information signal, which represents an operating state of the intruder alarm system. Unlike the primary illumination state, the secondary illumination state does not serve to transmit an optical alarm signal; Rather, information about the burglar alarm system itself, if appropriate even over long distances, for example several meters, can thus be output by the secondary light status. The information communicated by means of the secondary illumination state can in particular be a Feedback on an action of a user of burglar alarm system act, for example, to a successful input of a control command.

For example, activating (focusing), deactivating (disarming) or otherwise actuating the burglary alarm system can be optically acknowledged by the secondary illumination state. Such an optical acknowledgment increases the security of operation of the burglary alarm system remotely. For when, for example, the operation of the burglar alarm system by so-called jamming e.g. is hindered by a jammer, the acknowledgment remains off, so that as a result of the failure unsuccessful activation of the burglar alarm system can be recognized as such.

In particular, additional operating states of the burglary alarm system can be coded by using different secondary light states, for example the activated activation of the burglary alarm system with properly closed outer skin of the building (eg short-term lighting with the color green) and the activated or attempted activation of the burglar alarm system with not completely closed outer skin (eg window tilted, momentary lighting with the color yellow).

Another exemplary application is that a defined time delay between an activation operation of the burglar alarm system and the actual activation is indicated by the secondary illumination state. For example, a user can actuate the burglar alarm system within the building to be protected, for example at the alarm center, but then has time within the time delay until the actual activation to leave the building so as not to be alarmed by leaving the building itself trigger. From the outside, he can then recognize on the basis of the lighting device of the alarm device, when the time delay expired and the burglar alarm system is actually activated. For example, sem of the secondary light condition of the lighting device end, so that the lighting device then goes out. Such a secondary illumination state can, for example, have the color green, yellow or blue. By the secondary light state can also other operating conditions, such as a closed state of the outer skin of the building, eg windows and doors, or a malfunction of burglar alarm system, eg an interrupted communication connection to a component of the burglar alarm system, a low battery of a component or a full memory one Component to be displayed.

The optical signals which can be emitted by the luminous device, that is to say in particular the optical alarm signal emitted in the primary luminous state and the optical information signal which may be emitted in the secondary luminous state, are preferably widely visible with respect to their intensity and radiation. In particular, these optical signals are over a wide solid angle (for example at least one quarter sphere, a light cone having an aperture angle of at least about 30 °, preferably of at least about 60 °, or an azimuthal angle of at least about 60 °, preferably at least at least about 120 °, in particular at least about 180 °) substantially uniformly and / or non-specifically emitted light. The signals are in particular non-pictorial and / or contourless.

As an alternative or in addition to the representation of an operating state of the burglary alarm system, the secondary light state may include an illumination of an environment located below the alarm device. The same lighting device can therefore be designed to generate and emit an optical alarm signal on the one hand in the event of an alarm in accordance with the primary lighting state and, on the other hand, to illuminate an environment of the alarm device in accordance with the secondary lighting state. Lighting may be provided, in particular, by a be triggered by the control panel received control signal. This may in particular be the same control signal as for the triggering of the optical alarm signal, so that at least when the alarm device emits an optical alarm signal, at the same time also the mentioned environment is illuminated.

According to one embodiment, the lighting device is designed to emit an optical information signal as a result of activating, deactivating and / or a status query of the burglar alarm system. The optical information signal can thus serve the above-described acknowledgment or else comprise a kind of response to a specific request, in particular triggered by a user of the burglar alarm system. For example, in particular from outside a monitored building, it can be queried whether a particular operating mode or which of several possible operating modes of the burglar alarm system exists.

According to one embodiment, the lighting device has a light source with a variable light characteristic and / or a plurality of selectively controllable light sources. If only one light source is provided, both the primary illumination state and the secondary illumination state are realized by means of this light source. For this purpose, the luminous characteristic of the light source is variable, in particular with regard to the color emitted by the light source, in order to be able to emit light of the first color or light of the second color, depending on the luminous state. The color variability can be stepless, at least substantially over a certain color range.

However, the lighting device can also comprise at least two light sources of different color, so that different light states can be generated by their selective activation. In particular, a first light source of the lighting device is designed to emit light in the first color, and a second light source of the lighting device configured to emit light in the second color. However, it is also possible to provide further light sources, for example for generating further luminous states, or for the primary luminous state and / or the secondary luminous state to be produced by a respective group of multiple light sources, the multiple light sources of a group being able to be identical (eg to allow a higher luminous intensity and / or for the purpose of reliability or redundancy). If multiple light sources are provided, they may be generally adjacent to each other or remote from each other on the alarm device.

According to one embodiment, the lighting device comprises one or more light-emitting diodes (LEDs) as the respective light source. If the lighting device comprises only one LED, the LED is preferably color-modulatable in order to be able to selectively generate and emit light according to the primary light state and light according to the secondary light state by means of the same LED.

The named first color may in particular be red. An optical alarm signal emitted in the primary illumination state is then red. Since red light is the least scattered in comparison to other spectral ranges of visible light and therefore can be reliably perceived even from comparatively long distances, it is particularly well suited as an alarm color.

According to one embodiment, the first color and / or the second color is / are selectively adjustable from different predetermined colors or within a predetermined color range. This is advantageous if different colors are prescribed for the optical alarm signal of a burglary alarm system in different countries, because then a particularly simple adaptation to country-specific features is possible. The color of the secondary luminous state can be selected in particular with regard to it is particularly distinguishable from the color of the primary luminosity.

According to one embodiment, the lighting device is designed to selectively illuminate at least part of the monitoring zone with white light as a function of the received control signal. In this case, the illumination (of the part) of the monitoring zone corresponds to a secondary lighting state of the lighting device. To use light of at least essentially white color has the advantage that the color perception is least distorted by white light.

The illumination can be carried out in particular simultaneously with the emission of an optical alarm signal according to the primary illumination state. However, it can also be controlled by means of a separate control signal and thus decoupled from the primary illumination state. For example, the lighting device can be controlled to its illumination only in the event of an alarm event when a detected, the alarm event underlying irregularity was detected in an illuminable by means of the lighting device part of the surveillance zone. However, lighting can also be independent of an alarm event and, for example, can be time-dependent (for example at twilight and / or at night).

According to one embodiment, the alarm device has a housing in which the siren and the lighting device are integrated. The siren and the lighting device and optionally further, the functionality of the alarm device still expanding components, such as the detection device described below and / or camera, thus form a unit that is bounded by a common housing to the outside. This simplifies both the installation and the connection of the alarm device to a power supply and to the alarm center of the burglar alarm system. In particular, a common power supply be provided for all components of this unit. The alarm device may also offer the possibility of battery operation in which all components are then powered by the same battery or batteries. Furthermore, an emergency power supply can be provided.

The housing of the alarm device is preferably adapted to an attachment of the alarm device in the outer space (in particular on a building exterior wall). The housing may in particular be weatherproof and / or splash-proof, for example according to protection class IP-44 or higher.

According to one embodiment, the alarm device further comprises a detection device for detecting a movement in at least part of the monitoring zone, the detection device being adapted to generate a movement detection signal upon detection of a movement. For example, the detection device may comprise a per se known PIR sensor, the receiving or imaging optics preferably for a comparatively large detection range, in particular of at least about 4 m, designed to allow a correspondingly large mounting height of the alarm device, as they are for a Siren or signal light (although not for a detection device for detecting a movement) is common.

In this case, the alarm device preferably comprises a signal output for outputting the motion detection signal to the alarm center of the burglar alarm system. In this case, the detection device can be designed, in particular, to detect a movement in a region below the alarm device, and to this end be provided, for example, on a lower side of the alarm device, in particular arranged horizontally. This makes it possible, in particular, to recognize when a person is directly below the alarm device. moved bar along the building wall. The entire spatial area within which the detection device can reliably detect a movement can be greater than the said area vertically below the alarm device.

The detection device extends the functionality of the alarm device such that a region in the vicinity of the alarm device can automatically be monitored for movement, so that a separate detection device for this region can be dispensed with. In addition, the detection of movements in the vicinity of the alarm device can directly serve to secure the alarm device itself against unauthorized access and manipulation.

In particular, the detection device can not only output a respective movement detection signal to the alarm control center, but also use the movement detection signal to directly set the lighting device into a lighting state, preferably the secondary lighting state. This secondary illumination state can then in particular comprise illuminating the surroundings of the alarm device, preferably straight (at least substantially) of the area in which the movement was detected. The secondary illumination state may additionally or alternatively also comprise an optical information signal by means of which the presence of a movement in the vicinity of the alarm device can be visually displayed. As an alternative or in addition to a detection device for detecting a movement, the alarm device can also have different detection devices with which irregularities in the monitoring zone or at least part of the monitoring zone can be detected. In particular, it is also possible to provide a detection device which is designed to detect irregularities of the alarm device itself, for example due to an external input. To detect the effect. Such a detection device can be designed, for example, as sabotage contact, by which, in particular, a wall break-off, that is to say a release of the alarm device from the respective building wall, and / or an opening of the housing of the alarm device can be established.

According to one embodiment, the alarm device comprises a camera which is designed to detect or generate image data of at least part of the surveillance zone in response to the received control signal and / or a camera control signal. By way of example, the camera can be a still or moving-picture camera which can acquire optical information about at least part of the surveillance zone in the visible light range and / or other spectral ranges, such as infrared, as image data. The portion of the surveillance zone captured by the camera may or may not necessarily correspond to the aforementioned portions of the surveillance zone that are monitored or illuminated by other components of the intruder alarm system.

The detection of image data can be triggered in particular by a movement detection signal generated by the detection device. Thus, the camera can only generate image data to save energy and space required for the image data if movement in the surveillance zone has been detected.

Alternatively or additionally, the camera may capture image data in response to a control signal received from the alarm center. If the image data acquisition is to be activated in the event of an alarm event parallel to the siren, the control signal may be the same control signal as for the siren. In principle, however, it is also possible to provide a separate camera control signal for which the alarm device has a separate signal input. may or may be receivable via the same signal input as the control signal for the siren or for the lighting device.

The image data generated by the camera can be stored in the alarm device. As an alternative or in addition to this, provision can also be made for the image data to be transmitted to the alarm control center or to a separate storage device (for example local storage or cloud storage), for example by means of WLAN and / or based on an IP network. The output of the image data can take place via a signal output of the alarm device, which can be provided specifically for the image data or can also be used by other devices, such as the above-mentioned detection device.

The object is further achieved by a burglar alarm system with an alarm device, as described above, wherein the burglar alarm system comprises an alarm center for outputting the control signal to the alarm device. If the alarm device also includes one or more signal outputs, the alarm center may be further configured to receive respective signals (e.g., motion detection signals or image data) from the alarm device. In addition, the alarm center can be designed in particular for connection to further signaling device, detection devices and / or other components of the burglar alarm system.

According to one embodiment of the burglar alarm system, the alarm center is designed to detect an alarm event in the surveillance zone on the basis of a detection event received by the alarm device or other components of the burglary alarm system and, as a result of a detected alarm event, the siren for generating an audible alarm signal and / or the lighting device for Generate an optical alarm signal to control. According to one embodiment of the burglar alarm system, the alarm center is designed to detect an operating state of the intruder alarm system and to control the light device for generating an optical information signal representing the operating state and thus visually communicating the operating state. The determination of the operating state can be triggered, for example, from outside the alarm center or routinely autonomous and, for example, include the retrieval of data from components of the burglar alarm system. The object is further achieved by a method for operating a burglar alarm system with a light device having an alarm device, in particular an alarm device, as described above, wherein the light device is occasionally driven to generate an optical alarm signal or an optical information signal, wherein the optical Alarmsignal has a first color and wherein the optical information signal has a second color, which is different from the first color.

The lighting device is thus designed both to generate and emit an optical alarm signal and to generate and transmit an optical information signal, the optical alarm signal and the optical information signal differing at least in their color. As explained above, the alarm signal and the information signal are essentially uniformly emitted light, which does not comprise any pictorial information but is emitted substantially uniformly and / or unspecifically over a large solid angle. The signals can be distinguishable from each other in addition to their respective color by other characteristics such as the brightness, the emission direction, a time sequence and the transmission time. According to one embodiment of the method, the burglar alarm system comprises an alarm center, wherein the light-emitting device is actuated to emit an optical alarm signal when the alarm center detects an alarm event in a surveillance zone monitored by the burglar alarm system and emits an optical information signal when an operational state of the burglar alarm system changes and / or at the alarm center, an operating state of the burglar alarm system is queried.

According to one embodiment of the method, the lighting device is driven to emit an optical information signal as a result of activating, deactivating and / or a status query of the burglar alarm system. In a status query, an operating state of the burglar alarm system is queried.

The interrogation of an operating state of the intruder alarm system can be triggered from outside the burglar alarm system, for example by a user of the burglar alarm system, in particular manually. Alternatively, it may also be provided that, e.g. at certain times or at certain time intervals, queries are automatically triggered internally, in particular by an alarm center of the burglary alarm system.

The invention will be explained in more detail by way of example only with reference to the figures.

Fig. 1 shows a schematic representation of an embodiment of a

Alarm device as part of an embodiment of a burglar alarm system in a side view.

The alarm device 1 1 of an intruder alarm system 13 shown in FIG. 1 is designed as a compact unit in which various devices are combined to achieve a multifunctional functionality. Outwardly, the alarm Device 1 1 essentially delimited by a housing 15, in which the individual devices are accommodated, wherein they may project in part from the housing 15. On a rear wall of the housing 15 of the alarm device 1 1, a fixing portion 17 is formed, which serves for fastening the alarm device 1 1 to the building wall 19 and is formed reinforced in particular with respect to the rest of the housing 15. The attachment portion 17 extends in the illustrated position of use of the alarm device 1 1 substantially verti cal, so that screws 21, which extend through corresponding openings of the mounting portion 17 and are screwed into the building wall 19, are aligned vertically to each other. In this way, a tilting of the attached to the building wall 19 alarm device 1 1 can be prevented. It is not excluded that outside the plane of illustration of Fig. 1 further openings are provided with further screws 21.

The alarm device 1 1 can act as a signaling device of the burglar alarm system 13 and for this purpose comprises a siren 23, which can be controlled by means of a siren control signal to generate an acoustic alarm signal. The siren 23 is disposed in the vicinity of a front side of the housing 15, which openings (not shown) so that the optionally generated by the siren 23 acoustic alarm signal from the alarm device 1 1 out with the least possible attenuation can be emitted. Alternatively, the siren 23 can also be arranged on or at least in the vicinity of a rear side of the housing 15, whereby the emission of the alarm signal can also take place via the building wall 19 and parts of the building itself.

The emitting direction can be at least substantially horizontal in particular. The audible alarm signal optionally generated by the siren 23 indicates a sound pressure level of over 80 dB (A) at a distance of 1 m Siren 23 on and is therefore widely audible. In addition, this volume is suitable to be perceived by a person who is staying in an environment of the siren 23, as very unpleasant, so that the siren 23 can help to drive away an unauthorized intruded into the environment person.

For receiving the siren siren control signal, the alarm device 1 1 has a signal input 25 provided at the rear of the housing 15 and connected to the siren 23 (directly or via a control device, not shown). The signal input 25 is connected to an alarm center 27 of the burglar alarm system 13, which is mounted inside the building, on the building wall 19, the alarm device 1 1 is attached. In principle, instead of the illustrated wired connection, a radio-based connection between the signal input 25 and the alarm control center 27 may also be provided. In this case, the signal input 25 is formed, for example, as a radio receiver.

In addition to the alarm device 1 1 shown, the alarm center 27 can be connected to further alarm devices or other components of the burglar alarm system 13, for example detection devices and signaling devices of various types. In the alarm center 27 detection signals of various of these components can converge in this way. The alarm control center 27 may in particular be designed to take into account a plurality of detection signals in combination in order to ascertain, on the basis of the detection signals and optionally further parameters, by means of an evaluation logic, whether an alarm event is present. A respective detection signal does not necessarily have to represent an irregularity in the respective monitored area; rather, a detection signal may also include the information that there is no irregularity. If, as a result of the evaluation of the detection signals, the presence of an alarm event is detected, the alarm center 27 can generate and output control signals for actuating respective signaling devices. In particular, the alarm center 27 can output a control signal to the alarm device 1 1, which can then receive this via the signal input 25 and by which the alarm device 1 1 can thus be controlled to send an alarm signal.

In addition to the siren 23, the alarm device 1 1 also has a light device 29, which can be controlled to generate and transmit an optical alarm signal. In this way, the alarm device 1 1 advantageously both an acoustic and an optical alarm signal by means of the siren 23 and the light emitting device 29 emit, so that a detected alarm event can be signaled particularly clear. In principle, however, the alarm device 11 can also be activatable to emit the optical alarm signal as an alternative to the acoustic alarm signal. If an acoustic alarm signal and an optical alarm signal are always transmitted simultaneously, their respective generation by the siren 23 or the lighting device 29 can be caused by the same control signal.

The lighting device 29 of the alarm device 1 1 comprises in the embodiment shown at least two light sources 31, 33, wherein only to illustrate that thereby a jointly controllable lighting device 29 is formed, the two light sources 31, 33 are shown connected in Fig. 1 (see. broken line from the top of the housing 15 to the bottom). In a first light source 31 at the top of the housing 15 is an arrangement of a plurality of similar color modulatable LEDs, by means of which the lighting device 29 can act as a signal light and thereby to emit very intense light of different colors, especially on the one hand red light and on the other hand at least yellow, green and / or blue light, can be controlled.

The light generated by the light source 31 in each case is emitted substantially uniformly by the lighting device 29 via a solid angle corresponding to a hemisphere with a horizontal sectional area. In this case, it is possible in principle for the emission direction to be further restricted, for example by diaphragms and / or mirror surfaces. Preferably, the emitted light has no visual information.

A second light source 33 of the lighting device 29 is arranged such that it is suitable to illuminate an environment below the alarm device 1 1, in particular with at least substantially white light. In the illustrated embodiment, the second light source 33 is arranged on the underside of the housing 15 of the alarm device 1 1, but this is not mandatory. In this case, the second light source 33 of the lighting device 29 can respond to a control signal which it can receive via the signal input 25 (at least indirectly) from the alarm center 27. The activation of the second light source 33 can be independent of the activation of the siren 23 and / or the first light source 31, so that the second light source 33 is not limited to being activated for illumination in the event of a detected alarm event. However, it may be provided in particular that the second light source 33 is in any case actuated to illuminate when an alarm event is present.

If the lighting device 29 emits an optical alarm signal by means of the first light source 31, this corresponds to a primary light condition of the lighting device 29. The optical alarm signal has in particular the color red and is emitted as a rapid sequence of light flashes. The lighting device 29 can also be used to generate light of another color, in particular green, blue and / or yellow, by means of the first light source 31 in order to emit an optical information signal which, unlike the optical alarm signal, does not correspond to an alarm event, but instead to an alarm signal Operating state of the burglar alarm system 13 represents. The optical information signal may include for signaling a successful activation of the burglar alarm system 13 with properly closed outer skin of the building a short-term glow with the color green and for signaling a successful activation of the burglar alarm system 13 with not completely closed outer skin include a brief glow with the color yellow , The emission of an optical information signal corresponds to a secondary illumination state of the lighting device 29 and, in particular, in any case includes a different color than the optical alarm signal.

The lighting device 29 of the alarm device 1 1 shown in FIG. 1 can furthermore assume at least one further secondary lighting state by means of its second light source 33. This includes the illumination of the environment below the alarm device 1 1 with at least substantially white light emitted by the second light source 33. In such an illuminating secondary illumination state, therefore, there is no information transmission in the foreground. Rather, it serves to brighten the environment, for example, to be able to discover an intruder or at least to make undetected an intrusion into the environment of the alarm device 1 1. In particular, provision may be made for the lighting device 29 to occupy this illuminating secondary illumination state at least in each case when an alarm event exists and, as a result, the primary illumination state is also triggered by the optical alarm signal.

Also in the respective secondary illumination state, the lighting device 29 is brought by means of a respective corresponding control signal which activates the alarm Direction 1 1 via the same signal input 25 can receive from the alarm center 27 as the control signal for generating an audible and / or visual alarm signal by means of the siren 23 and the first light source 31st In order to monitor an area vertically below the alarm device 1 1, in particular vertically between the alarm device 1 1 and a floor over which the alarm device may be mounted, for example, at a height of about 4.5 m, the alarm device 1 1 at the here illustrated embodiment, a detection device 35 for detecting a movement in this area. In this way, in particular a person can be detected, which moves vertically below the alarm device 1 1 directly on the building wall 19 along.

The detection device 35 can in particular be adapted to generate a movement detection signal upon detection of a movement, which can then be output to the alarm center 27, in particular to be taken into account by the alarm center 27 in the context of determining whether an alarm event exists , For this purpose, the alarm device 1 1 has a signal output 37 provided on a rear side of the housing 15, which is connected (directly or via a control device, not shown) to the detection device 35, and via which the alarm device 1 1 also to the alarm center 27 of Burglar alarm system 13 is connected. The connection to the alarm center 27 is wired in the illustrated example, but in principle may also be radio-based, wherein the signal output 37 then, for example, may be a radio transmitter.

In the exemplary embodiment illustrated here, the alarm device 11 also comprises a camera 39, which is accommodated in a lower front region of the housing 15 in order to be able to detect a large part of the environment vertically below the alarm device 11. The camera 39 is a Moving picture camera, the visual information in the visible and infrared

Capture the light spectrum to generate corresponding image data. It can be provided that the camera 39 can emit infrared light to improve the brightness and the contrast of the thus captured image data. The camera 39 is arranged in particular in the vicinity of the detection device 35 in order to achieve a large overlap of the region optically detectable by the camera 41 with the region detected by means of the detection device 35.

In principle, the camera 39 can be designed for permanent recording of image data. To reduce the energy and data storage requirements or the data throughput but can also be provided that the camera 39 does not permanently record the image data or that the image data is at least not permanent permanently stored, but that the camera 39 only as needed from the alarm center 27 for Capture the image data is controlled or captured image data only as needed permanently (instead of just temporarily stored in a circular buffer).

In particular, the camera 39 can respond to a camera control signal, which generates the alarm center 27 in response to received detection signals and possibly other parameters and transmitted via the signal input 25 of the alarm device 1 1 (at least indirectly) to the camera 39. In particular, a recording of image data can take place in any case when the detection device 35 detects a movement in the vicinity of the alarm device 11. Alternatively or additionally, the camera 39 can be controlled to a recording at least when the alarm center 27 outputs a control signal corresponding to an alarm event, by the same time the siren 23 and / or the first light source 31 of the lighting device 29 for emitting a respective acoustic or optical alarm signal is / will be controlled. The image data generated by the camera 39 can in principle be stored in a storage device, not shown, which may be integrated in the alarm device 11 or as a separate storage medium, eg as a recorder. Alternatively or additionally, the image data can also be transmitted to the alarm center 27, where it can be stored, forwarded (eg to a cloud storage) and / or evaluated. For the output of the image data, the alarm device 1 1 may have a separate image data output (not shown). In principle, the same signal output 37 as for the detection device 35 can be used for the output of the image data but also as shown in FIG.
