Description

Die Erfindung betrifft eine Vorrichtung zum Sichern von Fenstern, Türen oder dergleichen, mit an den zu sichernden Stellen vorgesehenen elektrischen Warneinrichtungen, welche jeweils einen unabhängigen Stromerzeuger, einen Sensor und einen signalerzeugenden Sender aufweisen, einem zentralen Empfänger für die durch die Sender erzeugten Signale und einer durch den Empfänger beaufschlagbaren Alarmeinrichtung.The invention relates to a device for securing windows, doors or the like, with provided at the points to be secured electrical warning devices, each having an independent power generator, a sensor and a signal-generating transmitter, a central receiver for the signals generated by the transmitter and one alarm device which can be acted upon by the receiver.

Fenster und Türen sind generell Schwachstellen des Einbruchschutzes. Aus diesem Grunde werden bei Alarmanlagen an Fenstern und Türen jeweils Sensoren angebracht, die einen Angriff auf Fenster bzw. Türen melden oder anzeigen sollen, daß eine dieser Gebäudeöffnungen versehentlich nicht geschlossen oder aber unbefugt geöffnet wurde. Derartige Systeme, welche alle Öffnungen eines Gebäudes einbeziehen, werden auch als "Außenhautschutz" bezeichnet. Daneben gibt es Alarmsysteme, die innerhalb des Gebäudes Veränderungen entdecken und melden sollen. Diese werden auch als "Bewegungsmelder" bezeichnet.Windows and doors are generally weak points in burglary protection. For this reason, sensors are attached to alarm systems on windows and doors to report or indicate an attack on windows or doors that one of these building openings was accidentally not closed or was opened without authorization. Systems of this type, which include all openings in a building, are also referred to as “outer skin protection”. There are also alarm systems designed to detect and report changes within the building. These are also known as "motion detectors".

Der Vorteil des"Außenhautschutzes" ist der, daß die Sensoren einen Angriff oder eine Fahrlässigkeit melden, bevor der Täter in das Gebäude eingedrungen ist. Damit werden die Vorwarnzeit verlängert und die Wahrscheinlichkeit, daß noch rechtzeitig Hilfe eintrifft, erhöht. Der Nachteil der Außenhautsysteme liegt in dem verhältnismäßig großen Aufwand für die Verdrahtung aller Gebäudeöffnungen. Dieser Nachteil tritt besonders dann auf, wenn ein Außenhautschutz in ein bereits bestehendes Gebäude eingebaut werden soll. Dabei müssen Wände aufgehackt werden, es muß beispielsweise nachtapeziert werden, außerdem sind die anfallenden Arbeiten mit Belästigung der Bewohner des Gebäudes durch Schmutz und handwerkliche Arbeiten verbunden.The advantage of "outer skin protection" is that the sensors report an attack or negligence before the perpetrator has entered the building. This increases the warning time and increases the likelihood that help will arrive in time. The disadvantage of the outer skin systems lies in the relatively large outlay for wiring all building openings. This disadvantage occurs particularly when an outer skin protection is to be installed in an already existing building. Walls have to be chopped up, it has to be re-taped, for example, and the work involved is associated with nuisance to the occupants of the building through dirt and manual work.

Aus der DE-OS 24 36 225 ist bereits eine Vorrichtung der eingangs genannten Art bekannt, welche die vorstehend beschriebenen Nachteile, die auf die bei Netzversorgung der einzelnen Sensoren bzw. der diesen nachgeordneten Warneinrichtungen auftretenden Nachteile dadurch zu vermeiden suchte, daß jede elektrische Warneinrichtung einen unabhängigen Stromerzeuger aufweist, also keinerlei Verdrahtung zwecks Stromversorgung benötigt. Der Stromerzeuger ist dabei mechanisch durch ein Öffnen des Fensters oder der Tür betätigbar, wobei der durch den Stromerzeuger in diesem Fall erzeugte Impuls über den Hochfrequenzsender ein Signal zum zentralen Empfänger schickt, ebenfalls drahtlos, aufgrund dessen dann die Alarmauslösung erfolgt. Nachteilig ist bei dieser Vorrichtung jedoch, daß der Stromerzeuger wegen seiner mechanischen Betätigbarkeit die Wahlmöglichkeit hinsichtlich der Sensoren begrenzt - beispielsweise können keine bewegungsfrei arbeitenden, beispielweise akustischen Sensoren verwendet werden -, wobei es auch nicht möglich ist, die Gesamtanlage "selbstüberwachend" arbeiten zu lassen, daß heißt also durch permanenten Signalfluß zwischen den Sendern und dem Empfänger im Nicht-Alarmzustand. Aus der DE-OS 24 37 341 ist andererseits eine Sicherheitsalarmvorrichtung bekannt, welche eine vielseitigere Auswahlmöglichkeit hinsichtlich der Sensoren gewährleistet und auch eine Selbstüberwachung der beschriebenen Art ermöglicht, jedoch sind dabei als Stromerzeuger jeweils Batterien vorgesehen, die naturgemäß stark wartungsbedürftig sind.From DE-OS 24 36 225 a device of the type mentioned is already known, which has the disadvantages described above, which to those in the network tried to avoid supplying the individual sensors or the disadvantages associated with these subordinate warning devices in that each electrical warning device has an independent power generator, so no wiring is required for the power supply. The power generator can be actuated mechanically by opening the window or the door, the pulse generated by the power generator in this case sending a signal to the central receiver via the high-frequency transmitter, likewise wirelessly, on the basis of which the alarm is then triggered. A disadvantage of this device, however, is that the power generator, because of its mechanical actuability, limits the choice with regard to the sensors - for example, no motion-free, for example acoustic, sensors can be used, and it is also not possible to let the entire system work "self-monitoring", that means through permanent signal flow between the transmitters and the receiver in the non-alarm state. From DE-OS 24 37 341, on the other hand, a security alarm device is known which ensures a more versatile selection with regard to the sensors and also enables self-monitoring of the type described, but batteries are provided as power generators, which naturally require a great deal of maintenance.

Selbst wenn man die Batterien als nachladbare Akkumulatoren oder aber auswechselbar ausbildete, stellen sich hohe Anforderungen an die Zuverlässigkeit sowohl des Personals als auch der Batterien bzw. Akkumulatoren, so daß ein einwandfreier Betrieb nicht mit Sicherheit gewährleistet ist.Even if the batteries were designed as rechargeable batteries or exchangeable, high demands are placed on the reliability of both the personnel and the batteries or accumulators, so that proper operation cannot be guaranteed with certainty.

Der Erfindung liegt die Aufgabe zugrunde, die Vorrichtung der eingangs genannten Art dahingehend weiterzubilden, daß bei größerer Flexibilität hinsichtlich der verwendbaren Sensoren eine höhere Betriebssicherheit gewährleistet ist.The invention has for its object to develop the device of the type mentioned in such a way that with greater flexibility visibly the sensors that can be used, higher operational reliability is guaranteed.

Erfindungsgemäß wird diese Aufgabe dadurch gelöst, daß die Stromerzeuger für die einzelnen elektrischen Warneinrichtungen strahlungs- oder thermoelektrische Energieumwandler, wie Solarzellen, Photoelemente oder Thermosäulen, aufweisen.According to the invention, this object is achieved in that the power generators for the individual electrical warning devices have radiation or thermoelectric energy converters, such as solar cells, photo elements or thermopiles.

Erfindungsgemäß wird auch eine Vorrichtung der gattungsgemäßen Art vorgeschlagenen, welche dadurch gekennzeichnet ist, daß die Sender im Nicht-Alarmzustand ein gepulstes Ruhesignal ausstrahlen. Diese Ausführungsform der Erfindung, die auch beispielsweise bei Verwendung von Stromerzeugern der aus der DE-OS 24 36 225 bekannten Art von Vorteil ist, ermöglicht eine zusätzliche Sicherung gegen einen Ersatz des echten Ruhesignales durch ein simuliertes Ruhesignal.According to the invention, a device of the generic type is also proposed, which is characterized in that the transmitters emit a pulsed idle signal in the non-alarm state. This embodiment of the invention, which is also advantageous, for example, when using power generators of the type known from DE-OS 24 36 225, enables an additional safeguard against a replacement of the real idle signal by a simulated idle signal.

Vorzugsweise kann vorgesehen sein, daß den Stromerzeugern jeweils ein Akkumulator oder dergleichen nachgeschaltet ist.It can preferably be provided that an accumulator or the like is connected downstream of the power generators.

Erfindungsgemäß kann auch vorgesehen sein, daß der Alarmeinrichtung mindestens ein Bewegungsmelder vorgeschaltet ist, der durch den Empfänger in Abhängigkeit von den erhaltenen Signalen beaufschlagbar ist.According to the invention it can also be provided that the alarm device is preceded by at least one motion detector which can be acted upon by the receiver in dependence on the signals received.

Weiterhin schlägt die Erfindung vor, daß die Sender im Nicht-Alarmzustand gegebenenfalls ein Ruhesignal ausstrahlen.Furthermore, the invention proposes that the transmitters may emit an idle signal in the non-alarm state.

Durch die Erfindung wird weiterhin eine Vorrichtung der beschriebenen Art mit Photoelementen als Stromerzeuger vorgeschlagen, welche gekennzeichnet ist durch eine zentrale Strahlungsquelle zur Beaufschlagung der Photoelemente mit Strahlungsenergie.The invention also provides a device of the described type with photo elements as a power generator, which is characterized by a central radiation source for applying radiation energy to the photo elements.

Gegenstand der Erfindung ist weiterhin eine Vorrichtung, welche sich dadurch auszeichnet, daß die Sender über ein Reservoir von mehreren unterschiedlichen Pulsgruppen verfügen, die von einem Zufallsgenerator als Ruhesignal gesteuert abrufbar sind, wobei der Empfänger durch ein Sondersignal erfährt, welche Pulsgruppe als nächstfolgende zu erwarten ist.The invention furthermore relates to a device which is characterized in that the transmitters have a reservoir of a number of different pulse groups which can be called up in a controlled manner as a quiescent signal by a random generator, the receiver being informed by a special signal which pulse group is to be expected as the next one .

Dabei kann insbesondere vorgesehen sein, daß die Art des Sondersignales sowohl von der nächstfolgenden Pulsgruppe als auch von mindestens einer vorangegangenen Pulsgruppe abhängt; und daß der Empfänger über einen Diskriminator zur Überprüfung der Form der ankommenden Pulsgruppe hinsichtlich ihrer Übereinstimmung mit der verfügt, die aufgrund des Sondersignals zu erwarten ist.In particular, it can be provided that the type of special signal depends both on the next pulse group and on at least one previous pulse group; and that the receiver ulsgruppe for compliance with the features that can be expected due to the special signal over a discriminator for checking the shape of the incoming P.

Weiterhin ist Gegenstand der Erfindung die Verwendung einer Vorrichtung der vorstehend beschriebenen Art zum Sichern von mit Alarmglasscheiben verschlossenen Gebäudeöffnungen, wobei die Sensoren auf Scheibenbruch ansprechen.The invention furthermore relates to the use of a device of the type described above for securing building openings closed with alarm glass panes, the sensors responding to pane breakage.

Dabei kann erfindungsgemäß vorgesehen sein, daß.die Sensoren bei Verwendung von Alarmglas-Doppelscheiben an der jeweiligen Innenscheibe angebracht sind.It can be provided according to the invention that the sensors are attached to the respective inner pane when using alarm glass double panes.

Schließlich kann erfindungsgemäß auch vorgesehen sein, daß die Warneinrichtungen vollständig in die jeweiligen Scheibenzwischenräume integriert sind.Finally, it can also be provided according to the invention that the warning devices are fully integrated into the respective inter-pane spaces.

Dadurch, daß bei der Erfindung dem jeweiligen Sensor zugeordnete strahlungs- oder thermoelektrische Energieumwandler zur Stromerzeugung verwendet werden, ist einerseits eine außerordentliche Flexibilität in der Auswahl der Sensoren gewährleistet, wobei diese beispielsweise in an sich bekannter Weise zum Entdecken beispielsweise eines Einschlagens der äußeren Scheibe einer Doppelverglasung, eines Zerschneidens der äußeren Scheibe mit Diamantwerkzeug oder ähnlichem, einer Manipulation an der inneren Scheibe oder auch eines Öffnens oder Offenstehens des Fensters oder der Tür ausgelegt sein können. Die permanente Stromversorgung gibt weiterhin die Möglichkeit, die einzelnen Sender permanent vorzugsweise gepulste Signale an den Empfänger aussenden zu lassen, so daß also Alarm dann ausgelöst wird, wenn die Signale ausbleiben. Die Sender selbst können natürlich beispielsweise so ausgebildet sein, daß sie Schall-, Ultraschall-, Infrarot- oder auch Hochfrequenzsignale, bzw. elektromechanische oder elektrornagnetische Schwingungssignale allgemein, aussenden, selbstverständlich bei entsprechender Ausbildung des Empfängers.Due to the fact that in the invention radiation or thermoelectric energy converters assigned to the respective sensor are used to generate electricity, on the one hand an extraordinary flexibility in the selection of the sensors is guaranteed, this being known, for example, in a manner known per se for discovering, for example, a break in of the outer pane of double glazing , a cutting of the outer pane with a diamond tool or the like, manipulation of the inner pane or also opening or opening of the window or the door can be designed. The permanent power supply also gives the possibility of having the individual transmitters permanently transmit preferably pulsed signals to the receiver, so that an alarm is triggered when the signals fail to appear. The transmitter itself can of course be designed, for example, so that it sonic, ultrasonic, infrared or high frequency signals, b z w. Electromechanical or electro-magnetic vibration signals in general, send out, of course, with appropriate training of the receiver.

Die Sensoren bzw. die diesen zugeordneten Stromerzeuger werden in dem Fall, daß es sich um Solarzellen handelt, beispielsweise an einer Glasscheibe oder an einem verglasten Teil einer Tür so angebracht, daß sie mit hinreichend Sonnenenergie beaufschlagt werden, um mit verhältnismäßig kleinen Solarzellen den Akkumulator aufladen zu können. Finden Photoelemente in Verbindung mit einer zentralen Strahlungsquelle, die innerhalb des zu sichernden Raumes oder Gebäudes angebracht ist, Verwendung, so ist natürlich für einen ungestörten Strahlenweg zwischen der Strahlungsquelle und den einzelnen Photoelementen Rechnung zu tragen, wobei bei dieser Ausführungsform ein besonderer Vorteil darin liegt, daß eine von natürlichen Einflüssen, nämlich Schwankungen der Sonnenenergie, frereEnergieversorgung der Warneinrichtungen gewährleistet ist. Auch eine Einflußnahme beispielsweise durch Abdecken der Solarzellen von außen oder dergleichen ist bei dieser Ausführungsform nicht zu besorgen. Bestehen die Energieumwandler aus Thermosäulen, welche die Temperaturdifferenz zwischen dem Gebäudeinneren und der Außenatmosphäre ausnutzen, so empfiehlt sich gegebenenfalls die Zwischenschaltung eines Spannungswandlers und/oder aber auch eine bekannte -Schaltung mit Sperrdioden, um zu verhindern, daß sich der Akkumulator bei unzureichender Thermospannung über die Thermosäule entlädt. Wird eine Grätz-Schaltung verwendet, so ist die Thermospannung unabhängig von der Polarität nutzbar.In the case that solar cells are involved, the sensors or the power generators assigned to them are attached, for example, to a glass pane or to a glazed part of a door in such a way that they are subjected to sufficient solar energy to charge the accumulator with relatively small solar cells to be able to. If photo elements are used in connection with a central radiation source, which is installed within the room or building to be secured, then this is the case to take into account, of course, for an undisturbed radiation path between the radiation source and the individual photoelements, a particular advantage in this embodiment being that an energy supply to the warning devices that is natural due to natural influences, namely fluctuations in solar energy, is ensured. Also influence, for example, by covering the S olarzellen from the outside or the like is to be feared in this embodiment. If the energy converters consist of thermopiles that take advantage of the temperature difference between the inside of the building and the outside atmosphere, then it may be advisable to interpose a voltage converter and / or a known circuit with blocking diodes in order to prevent the accumulator from being exposed to insufficient thermal voltage Thermopile discharges. If a Grätz circuit is used, the thermal voltage can be used regardless of the polarity.

Bei allen Ausführungsformen kann die Signalabgabe über die einzelnen Sender an den zentralen Empfänger beispielsweise ähnlich der Fernsteuerung von Fernseh- und Rundfunkgeräten erfolgen. Eine andere Möglichkeit besteht darin, daß der Sensor in einem zusätzlich vorgesehenen Bewegungsmelder bzw. in mehreren Bewegungsmeldern eine Bewegung simulierend das überwachte Feld in ähnlicher Weise stört wie ein unerwünschter Eindringling, wodurch es dann über den Bewegungsmelder zur Alarmauslösung kommt.In all embodiments, the signal can be output via the individual transmitters to the central receiver, for example similarly to the remote control of television and radio devices. Another possibility is that the sensor in an additionally provided motion detector or in a plurality of motion detectors disturbs the motion of the monitored field in a manner similar to an undesired intruder, which then triggers an alarm via the motion detector.

Die erfindungsgemäße Vorrichtung kann leicht in marktübliche Alarmsysteme integriert werden. Beispielsweise existieren Alarmanlagen, bei denen Bewegungsmelder in die Steckdosen eingesteckt werden und die über ein hochfrequentes Signal über die Lichtleitung mit einer Zentrale verbunden sind. Derartigen Bewegungsmeldern können dann die drahtlosen Sensoren an den Fenstern bzw. Türen mittels der erfindungsgemäßen Vorrichtung schaltungsmäßig zugeordnet werden.The device according to the invention can easily be integrated into commercially available alarm systems. For example, there are alarm systems in which motion detectors are plugged into the sockets and which are connected to a control center via a high-frequency signal via the light line. The wireless sensors on the windows or doors can then be assigned in terms of circuitry to such motion detectors by means of the device according to the invention.

Weitere Merkmale und Vorteile der-Erfindung ergeben sich aus den Ansprüchen,und aus der nachfolgenden Beschreibung, in der ein Ausführungsbeispiel anhand der schematischen Zeichnung im einzelnen erläutert ist. Dabei zeigt:

  • Fig. 1 ein Ausführungsbeispiel einer Vorrichtung nach der Erfindung in diagrammartiger Übersichtsdarstellung; und
  • Fig. 2 die Warneinrichtung der Vorrichtung von Fig. 1 in Blockdiagrammdarstellung.
Further features and advantages of the - invention will become apparent from the claims and from the following description in which an exemplary embodiment is explained with reference to the schematic drawing. It shows:
  • Figure 1 shows an embodiment of a device according to the invention in a diagrammatic overview. and
  • Fig. 2 shows the warning device of the device of Fig. 1 in block diagram representation.

Wie aus der Zeichnung ersichtlich ist, sind bei der dort gezeigten Vorrichtung Fenster 10, 12 durch elektrische Warneinrichtungen 14, 16 gesichert. Fig. 2 zeigt, daß jede Warneinrichtung eine Solar- zellenapordnung 18 mit nachgeschaltetem Akkumulator als Stromerzeuger aufweist. Ferner weist jede Warneinrichtung 14, 16 einen Sensor 20 zum Nachweis eines unbefugten öffnens eines der Fenster 10, 12 auf. Die Sensoren 20 können dabei in an sich bekannter Weise so ausgerüstet werden, daß sie beispielsweise auf das Einschlagen der äußeren Scheibe einer Doppelverglasung, ein Zerschneiden der Außenscheibe einer Doppelverglasung mit einem Diamantwerkzeug oder dergleichen, die Manipulation an einer Innenscheibe einer Doppelverglasung oder schließlich auch auf das Öffnen oder Offenstehen des Fensters oder der Tür ansprechen. Vorzugsweise sind die Sensoren 20 dabei in bekannter Weise als Elemente eines elektrischen Ruhestromkreises geschaltet. Sind die Sensoren 20 direkt auf Glasscheiben angebracht, so können sie in bekannter Weise für besondere Geräusche des Glases sensibilisiert werden (Glasbruch, Schneidgeräusch), wodurch die Möglichkeit von Fehlalarmen durch beispielsweise Donner und Hagel reduziert wird. Auch kann bei einer Isolierglasscheibe mit Gasfüllung das Eindringen von Luft in den Scheibenzwischenraum zur Alarmauslösung mittels der Sensoren 20 benutzt werden. Zum Nachweis des Öffnens von Fenstern und Türen kann ein Permanentmagnet am Fenster- oder Türrahmen angebracht werden, der beispielsweise mit einem Reed-Kontakt im Fensterrahmen in Verbindung steht und hierdurch anzeigen kann, daß das Fenster oder die Tür offensteht oder geöffnet wurde.As can be seen from the drawing, windows 10, 12 are secured by electrical warning devices 14, 16 in the device shown there. Fig. 2 shows that each warning means comprises solar cells A p proper 18 with a downstream battery as a power generator. Furthermore, each warning device 14, 16 has a sensor 20 for detecting a unauthorized opening of one of the windows 10, 12. The sensors 20 can be equipped in a manner known per se in such a way that, for example, they break in the outer pane of double glazing, cut the outer pane of double glazing with a diamond tool or the like, manipulate an inner pane of double glazing or finally also on that Address opening or opening of the window or door. The sensors 20 are preferably connected in a known manner as elements of an electrical closed circuit. If the sensors 20 are mounted directly on glass panes, they can be sensitized in a known manner to special noises in the glass (broken glass, cutting noise), which reduces the possibility of false alarms, for example due to thunder and hail. In the case of an insulating glass pane filled with gas, the penetration of air into the space between the panes can be used to trigger the alarm by means of the sensors 20. To prove the opening of windows and doors, a permanent magnet can be attached to the window or door frame, which is connected, for example, to a reed contact in the window frame and can thereby indicate that the window or door is open or has been opened.

Die Solarzellenanordnung 18 beaufschlagt bei dem in Fig. 2 gezeigten Ausführungsbeispiel der Warneinrichtung 14 nicht nur den Sensor 20, sondern insbesondere auch einen erfindungsgemäß vorgesehenen Sender 22, der bei dem gezeigten Ausführungsbeispiel gepulste Ultraschallsignale mit Impulsdauer von wenigen Millisekunden und Impulsabständen von ca. 30 Sekunden aussendet. In Fig. 2 ist angedeutet, daß auf die linke Seite der Solarzellenanordnung 18 in Richtung des Pfeiles Sonnenenergie auffällt, während der durch den Sender 22 abgesehene Signalstrahl in Fig. 2 nach rechts verläuft.In the embodiment of the warning device 14 shown in FIG. 2, the solar cell arrangement 18 acts not only on the sensor 20, but in particular also on a transmitter 22 provided according to the invention, which in the embodiment shown shows pulsed ultrasound signals with a pulse duration of a few milliseconds and pulse intervals of about 30 seconds. In Fig. 2 it is indicated that on the left side of the solar cell arrangement 18 in the direction of the arrow solar energy is striking, while the signal beam apart from the transmitter 22 extends to the right in Fig. 2.

Wie Fig. 1 zeigt, weist die erfindungsgemäße Vorrichtung weiterhin einen zentralen Empfänger 24 auf, der die von den Sendern 22 der Warneinrichtungen 14, 16 ausgesandten Signalimpulse auffängt. Dem Empfänger 24 ist eine (nicht gezeigte) Alarmeinrichtung, beispielweise in Form einer Sirene oder eines automatischen Telefonnotrufwählers, nachgeschaltet.As shown in FIG. 1, the device according to the invention furthermore has a central receiver 24 which picks up the signal pulses emitted by the transmitters 22 of the warning devices 14, 16. The receiver 24 is followed by an alarm device (not shown), for example in the form of a siren or an automatic emergency telephone dialer.

Das beschriebene Ausführungsbeispiel der Erfindung arbeitet wie folgt: Solange kein Einbruch vorliegt bzw. die Fenster 10, 12 nicht geöffnet werden, senden die Sender 22 der elektrischen Warneinrichtungen 14, 16 die gepulsten Signale aus, die demzufolge kontinuierlich von dem zentralen Empfänger 24 aufgefangen werden. Nimmt der Empfänger innerhalb einer an den Impulsabstand angepaßten Zeitspanne von auch nur einem der Sender 22 der Warneinrichtungen 14, 16 keine Signale mehr auf, erfolgt in bekannter Weise die Alarmauslösung. Der Empfänger 24 kann dabei auch noch mit einem oder mehreren Bewegungsmelder(n) gekoppelt sein, wobei durch die von den Sendern 22 ausgehenden Signale dann bei deren Ausbleiben im entsprechenden Bewegungsmelder eine Störung simuliert und daraufhin der Alarm ausgelöst wird.The described exemplary embodiment of the invention works as follows: As long as there is no break-in or the windows 10, 12 are not opened, the transmitters 22 of the electrical warning devices 14, 16 send out the pulsed signals, which are consequently continuously picked up by the central receiver 24. If the receiver no longer receives signals from even one of the transmitters 22 of the warning devices 14, 16 within a period of time adapted to the pulse interval, the alarm is triggered in a known manner. The receiver 24 can also be coupled to one or more motion detectors, the signals emitted by the transmitters 22 then simulating a malfunction when they are absent in the corresponding motion detector and the alarm is then triggered.

Die in der vorstehenden Beschreibung, in der Zeichnung sowie in den Ansprüchen offenbarten Merkmale der Erfindung können sowohl einzeln als auch in beliebigen Kombinationen für die Verwirklichung der Erfindung in ihren verschiedenen Ausführungsformen wesentlich sein.The features of the invention disclosed in the above description, in the drawing and in the claims can be essential both individually and in any combination for realizing the invention in its various embodiments.
