Weiterhin betrifft die Erfindung einen Gefahrenmelder, welcher zur lösbaren Aufnahme in einem konstruktiv darauf abgestimmten Meldersockel ausgebildet ist, wobei der Gefahrenmelder an seiner dem Meldersockel zugewandten Seite eine Reihe von ersten elektrischen Kontakten aufweist, die im aufgenommenen Zustand des Gefahrenmelders im Meldersockel eine Reihe von gegenüberliegenden, zweiten Kontakten kontaktieren. Von denen ist ein erster Teil zum Anschluss an einer Melderleitung oder Melderlinie zumindest zur elektrischen Stromversorgung des Gefahrenmelders vorgesehen. Weiterhin ist von denen ein zweiter Teil nicht zum Anschluss an die Melderleitung vorgesehen. Weiterhin weist der Gefahrenmelder eine elektronische Steuerung zur Steuerung des Gefahrenmelders auf.Furthermore, the invention relates to a hazard detector, which is designed for releasable inclusion in a structurally matched detector base, the danger detector on its side facing the detector base side a series of first electrical contacts, in the recorded state of the danger detector in the detector base a number of opposite, contact second contacts.

Bei den betrachteten Gefahrenmeldern handelt es sich um Punktmelder. Sie können z.B. Brand- oder Rauchmelder sein. Vorzugsweise handelt es sich bei diesen Brand- oder Rauchmeldern um optische Brandmelder, welche eine nach dem Streuprinzip arbeitende optische Detektoreinheit zur Detektion von Rauchpartikeln aufweisen. Sie können alternativ oder zusätzlich eine nach dem akustooptischen Prinzip arbeitende Detektoreinheit oder einen Gassensor zur Detektion brandtypischer Gase aufweisen. Weiterhin können die Gefahrenmelder akustische Alarmgeber, sogenannte "Sounder" sein. Sie können Blitzleuchten sein, sogenannte "Beacon", oder eine Kombination davon, sogenannte "Sounder Beacon". Schliesslich kann der Gefahrenmelder ein Intrusionsmelder zur Detektion eines möglichen Einbruchs sein.The hazard detectors considered are point detectors. They can be eg fire or smoke detectors. These fire or smoke detectors are preferably optical fire detectors which have an optical detector unit, which operates according to the scattering principle, for the detection of smoke particles. Alternatively or additionally, they may have a detector unit operating according to the acoustooptic principle or a gas sensor for detecting flammable gases. Furthermore, the hazard alarm can be acoustic alarm, so-called "sounder". They can be flashing lights, so-called "Beacon", or a combination of them, so-called "Sounder Beacon". Finally, the danger detector an intrusion detector to detect a possible burglary.
Weiterhin sind die betrachteten Gefahrenmelder über eine gemeinsame Melderleitung, insbesondere über eine Zweidrahtleitung, signal- und/oder datentechnisch mit einer Brandmelderzentrale verbunden. Es können mehrere derartiger Gefahrenmelder in Meldergruppen oder Melderlinien an eine Gefahrenmeldezentrale angeschlossen sein, über die typischerweise auch die elektrische Versorgung der Gefahrenmelder mit Strom versorgt.Furthermore, the considered hazard detectors via a common detector line, in particular via a two-wire line, signal and / or data technology connected to a fire alarm panel. Several such hazard detectors can be connected in detector zones or detector lines to a danger control center, which typically also supplies the electrical supply of the hazard alarm with electricity.
Die Gefahrenmelder können unterschiedliche Betriebsarten aufweisen. Das heisst er kann unterschiedlich konfiguriert bzw. parametriert sein, wobei als eine Betriebsart auch die jeweilige Kombination mehrerer unterschiedlicher Funktionalitäten erfasst ist, die nicht direkt funktional miteinander in Beziehung stehen.The hazard detectors can have different operating modes. This means that it can be configured or parameterized differently, whereby the respective combination of several different functionalities that are not directly functionally related to one another is also recorded as one operating mode.
Im Falle eines Brandmelders können z.B. unterschiedliche Empfindlichkeitsstufen, wie z.B. über DIP-Schalter oder Kontaktbrücken, eingestellt werden. Dadurch kann z.B. die Ansprechzeit und/oder die Detektionsschwelle zur Detektion von Rauch geändert werden, je nachdem, ob der Brandmelder z.B. in einem Bürogebäude oder in einer Schweisserei eingesetzt werden soll. Im Falle eines akustischen und/oder optischen Alarmgebers können z.B. unterschiedliche Werte für die Lautstärke, für die Blitzfolge oder für Alarmtonintervalle eingestellt werden. Im Falle eines Intrusionsmelders können z.B. unterschiedliche Empfindlichkeitsschwellen eingestellt werden. Auch ist es möglich, dass die sogenannte "Anti-Masking"-Funktion ein- oder ausgeschaltet wird.In the case of a fire alarm, e.g. different sensitivity levels, e.g. via DIP switches or contact bridges. Thereby, e.g. the response time and / or detection threshold for detecting smoke may be changed depending on whether the fire detector is e.g. to be used in an office building or in a welding shop. In the case of an audible and / or visual alarm, e.g. different values are set for the volume, for the flash sequence or for alarm tone intervals. In the case of an intrusion detector, e.g. different sensitivity thresholds are set. It is also possible that the so-called "anti-masking" function is turned on or off.
Anstelle der Schalter ist auch eine Parametrierung über eine Programmierschnittstelle oder über die Melderleitung durch die Brandmelderzentrale möglich.Instead of the switches, parameterization via a programming interface or via the detector cable is possible through the fire alarm control panel.
Nachteilig daran ist, dass bei einem Tausch des Gefahrenmelders dieser gegebenenfalls neu parametriert werden muss.The disadvantage of this is that when replacing the danger detector this may need to be reparameterized.
Es ist somit eine Aufgabe der Erfindung, ein verbessertes Verfahren für die Einstellung der Betriebsart sowie einen verbesserten Gefahrenmelder anzugeben.It is therefore an object of the invention to provide an improved method for setting the operating mode and an improved hazard detector.
Diese Aufgaben werden durch die Gegenstände der unabhängigen Patentansprüche gelöst. Vorteilhafte Ausführungsformen der vorliegenden Erfindung sind in den abhängigen Ansprüchen beschrieben.These objects are achieved by the subject-matter of the independent claims. Advantageous embodiments of the present invention are described in the dependent claims.
Erfindungsgemäss wird ein im Meldersockel des Gefahrenmelders angebrachter Zweipol zum Einstellen von zumindest zwei Betriebsarten des Gefahrenmelders verwendet, wobei ein elektrischer Kennwert des Zweipols über zwei im aufgenommenen Zustand des Gefahrenmelder miteinander kontaktierende elektrische Kontaktpaare durch eine elektronische Steuerung des Gefahrenmelders elektrisch ausgelesen wird.According to the invention, a dipole mounted in the detector base of the hazard detector is used for setting at least two operating modes of the hazard alarm, whereby an electrical characteristic of the dipole is electrically read out by two electrical contact pairs contacting each other in the recorded state of the hazard alarm by an electronic control of the hazard alarm.
Der Zweipol kann ein passives Bauelement sein, wie ein elektrischer Widerstand, eine Spule oder ein Kondensator. Er kann eine Diode oder Z-Diode sein. Der Zweipol kann auch eine Kombination davon sein, wie z.B. eine Reihenschaltung und/oder Parallelschaltung davon, wobei diese dann zwei Anschlüsse zum Anschliessen dieses Zweipols aufweisen. Der elektrische Kennwert des Zweipols ist in entsprechender Weise ein Widerstandswert, ein Kapazitätswert, ein Induktivitätswert, eine Diodendurchlassspannung oder eine Zenerspannung. Sie kann auch eine Resonanzfrequenz bei einer Reihen- oder Parallelschaltung einer Spule und eines Kondensators sein.The dipole may be a passive device, such as an electrical resistor, a coil or a capacitor. It can be a diode or zener diode. The dipole may also be a combination thereof, e.g. a series circuit and / or parallel circuit thereof, which then have two terminals for connecting this two-pole. The electrical characteristic of the two-pole is correspondingly a resistance value, a capacitance value, an inductance value, a diode forward voltage or a Zener voltage. It may also be a resonant frequency in a series or parallel connection of a coil and a capacitor.
Dadurch ist auf vorteilhaft einfache Weise eine durch den Meldersockel vorgegebene ortsbezogene Einstellung einer gewünschten Betriebsart möglich. Dadurch ist weiterhin bei einem Tausch des Gefahrenmelders keine Parametrierung bzw. Einstellung der gewünschten Betriebsart mehr erforderlich. Der Wartungsaufwand vereinfacht sich.As a result, a predetermined by the detector base location-related adjustment of a desired mode is possible in an advantageously simple manner. As a result, parameterization or adjustment of the desired operating mode is no longer required when replacing the hazard alarm. The maintenance effort is simplified.
Darüber hinaus ist weiterhin eine Kompatibilität zu bestehenden Meldersockeln gegeben. Für den Fall, dass kein gültiger elektrischer Kennwert ausgelesen werden kann, also wenn sich z.B. überhaupt kein Zweipol im Meldersockel befindet, wird eine Default-Betriebsart für den Gefahrenmelder, das heisst eine Standard-Betriebsart, eingestellt.In addition, there is still compatibility with existing detector bases. In the event that no valid electrical characteristic can be read, so if, for example, no two-pole in the detector base, a default mode for the hazard detector, ie a standard mode is set.
Nach einer Verfahrensvariante wird für die Einstellung der gewünschten Betriebsart ein entsprechender Parametersatz und/oder ein entsprechendes Betriebsprogramm von der elektronischen Steuerung geladen. Typischerweise erfolgt die Einstellung der Betriebsart dadurch, dass die für die Ausführung der Betriebsart relevanten Parameter, wie z.B. Zeitwerte, Detektionsschwellenwerte etc., geändert werden. Alternativ können im Falle der Verwendung einer prozessorgestützten Steuereinheit, wie z.B. eines Mikrocontrollers, mehrere Softwareprogramme in einem Speicher des Mikrocontrollers geladen sein, welche jeweils zum Ausführen einer Betriebsart vorgesehen sind. Die Auswahl des vom Mikrocontroller auszuführenden Softwareprogramms erfolgt durch eine Auswahlprogrammroutine, welche den erfassten elektrischen Kennwert in entsprechender Weise auswertet.According to a variant of the method, a corresponding parameter set and / or a corresponding operating program is loaded by the electronic controller for setting the desired operating mode. Typically, the adjustment of the mode is performed by having the parameters relevant to the execution of the mode, such as, e.g. Time values, detection thresholds, etc., to be changed. Alternatively, in the case of using a processor-based control unit, such as e.g. a microcontroller, a plurality of software programs may be loaded in a memory of the microcontroller, which are each provided for executing a mode. The selection of the software program to be executed by the microcontroller is carried out by a selection program routine which evaluates the detected electrical characteristic in a corresponding manner.
Einer weiteren Verfahrenvariante zufolge wird zumindest ein Paar elektrischer Kontakte, welches üblicherweise bzw. bestimmungsgemäss zum externen Anschliessen eines optischen und/oder akustischen Alarmgebers zur Steigerung der Aufmerksamkeit in einem detektierten Gefahrenfall vorgesehen ist, zum Auslesen des elektrischen Kennwerts des Zweipols verwendet.A further variant of the method according to at least one pair of electrical contacts, which is usually or intended for external connection of an optical and / or acoustic alarm to increase the attention in a detected danger, used to read the electrical characteristic of the dipole.
Nach einer weiteren Verfahrenvariante wird zum Einstellen der jeweiligen Betriebsart ein geeigneter Widerstandwert für den elektrischen Widerstand ausgewählt, welcher einem der jeweiligen Betriebsart zugeordneten Vergleichswert, insbesondere innerhalb eines vorgebbaren Widerstandswertebereichs, zugeordnet ist. Dadurch ist durch geeignete Auswahl eines herkömmlichen elektrischen Widerstands, für den es eine Vielzahl gängig verfügbarer Widerstandswerte gibt, eine denkbar einfache Einstellung der Betriebsart möglich.According to a further variant of the method, a suitable resistance value for the electrical resistance is selected for setting the respective operating mode, which value is assigned to a comparison value assigned to the respective operating mode, in particular within a predefinable resistance value range. As a result, by a suitable selection of a conventional electrical resistance, for which there are a multiplicity of commonly available resistance values, a conceivably simple adjustment of the operating mode is possible.
Vorzugsweise ist der Zweipol ein elektrischer Widerstand mit Widerstandswerten im Bereich von 100 Ω bis 100 kΩ, insbesondere im kΩ-Bereich und insbesondere mit einer Nennverlustleistung von weniger als 1 Watt.Preferably, the two-terminal is an electrical resistance with resistance values in the range of 100 Ω to 100 k Ω , in particular in the k Ω range and in particular with a nominal power loss of less than 1 watt.
Vorzugsweise ist der Gefahrenmelder ein als Punktmelder ausgebildeter Brandmelder, ein akustischer Alarmgeber, ein optischer Alarmgeber oder ein Intrusionsmelder.The danger detector is preferably a fire detector designed as a point detector, an acoustic alarm device, an optical alarm device or an intrusion detector.

In diesem Fall wird ein "unendlich" hoher Widerstandswert durch die elektronische Steuereinheit 4 erfasst. Liegt dieser Wert über einen vorgebbaren Mindestwiderstandswert, wie z.B. 100 kΩ auf, so kann dieser Widerstandswert der Default-Betriebsart zugeordnet werden.To detect the resistance of the electrical resistance R1, for example, the current flowing through it or the voltage applied to it can be detected.
