Description

Die vorliegende Erfindung betrifft ein Verfahren zur Installation oder Inbetriebnahme eines linearen Rauchmelders, welcher einen nachfolgend als Melder bezeichneten Sender-/Empfängerteil mit einem Lichtsender und einem Lichtempfänger sowie einen dem Melder gegenüber liegend angeordneten Reflektor aufweist, wobei der Lichtsender einen Lichtstrahl zum Reflektor aussendet, der von diesem zum Lichtempfänger reflektiert wird.The present invention relates to a method for installing or commissioning a linear smoke detector, which hereinafter referred to as a detector transmitter / receiver part with a light transmitter and a light receiver and a detector opposite lying reflector arranged, wherein the light emitter a light beam to the reflector emitted, which is reflected by this to the light receiver.

Derartige auch als Linien Extinktionsmelder bezeichnete Rauchmelder werden insbesondere in grossen oder schmalen Räumen, beispielsweise in Korridoren, Lager- und Fabrikationshallen und in Flugzeughangars eingesetzt und unterhalb der Decke an den Wänden montiert. In der Standardausführung liegen Sender und Empfänger einander gegenüber und es ist kein Reflektor erforderlich. Diese wurden lange Zeit nur dann verwendet, wenn die Räume so kurz sind, dass die minimale Länge des Lichtstrahls von etwa 10 m sonst nicht erreicht würde, oder wenn die dem Sender gegenüberliegende Seite nicht stabil ist oder dort kein Empfänger installiert werden kann. Da aber die Ausführung mit dem Reflektor preisgünstiger und wesentlich einfacher zu installieren ist, setzen sich die linearen Rauchmelder mit Reflektor immer stärker durch.Such smoke detectors, also referred to as line extinction detectors, are used in particular in large or narrow spaces, for example in corridors, warehouses and production halls and used in aircraft hangars and mounted on the walls below the ceiling. In the By default, transmitter and receiver face each other and it is not Reflector required. These were only used for a long time when the rooms were so short are that the minimum length of the light beam of about 10 m would not otherwise be achieved, or if the side opposite the transmitter is not stable or there is no receiver installed can be. But since the design with the reflector cheaper and much more easier to install, the linear smoke detectors with reflector are getting stronger and stronger by.

Bei der Installation und Inbetriebnahme eines linearen Rauchmelders muss die Optik exakt ausgerichtet werden. Dieses Ausrichten der Optik auf den Reflektor stellt die schwierigste Operation der Installation/Inbetriebnahme dar und ausserdem sehr aufwändig, weil es die Mitarbeit von zwei Personen erfordert. Eine Person bedient den Melder und die andere Person muss den Reflektor so positionieren, dass das Ausgangssignal der Elektronik des Lichtempfängers maximal wird. Selbstverständlich kann auch zuerst der Reflektor montiert und dann der Melder auf diesen ausgerichtet werden, was aber an der Umständlichkeit und am Aufwand der Installation nichts ändert. Es gibt auch lineare Rauchmelder mit einem speziellen Justierset, das ist eine Art von Zieleinrichtung, die am Melder festgeklemmt und zu dessen Ausrichtung auf den bereits montierten Reflektor verwendet wird.When installing and commissioning a linear smoke detector, the optics must be exact be aligned. This alignment of the optics to the reflector is the most difficult Operation of the installation / commissioning dar and also very complex, because it is the Cooperation of two persons required. One person serves the annunciator and the other person must position the reflector so that the output signal of the electronics of the light receiver becomes maximum. Of course, first the reflector mounted and then the Detectors are aligned to these, but due to the complexity and effort of the Installation does not change anything. There are also linear smoke detectors with a special adjustment set that is a type of target device that is clamped at the detector and its orientation to the already mounted reflector is used.

Das Dokument US3614439 zeigt eine solche Methode zur Ausrichtung zweier parallel montierter Sichtgeräte mit Hilfe eines Spiegels.The document US3614439 shows such a method for aligning two parallel mounted viewing devices with the help of a mirror.

Durch die Erfindung sollen nun ein Verfahren zur Installation oder Inbetriebnahme eines linearen Rauchmelders und ein Werkzeug zur Durchführung dieses Verfahrens angegeben werden, welches den Installationsaufwand beträchtlich reduziert und vereinfacht. The invention will now be a method for installing or commissioning a linear smoke detector and a tool for performing this method which considerably reduces and simplifies the installation effort.

Beim erfindungsgemässen Verfahren wird also entweder zuerst der Melder montiert, dann das Installationswerkzeug auf den Sender-/Empfängerteil aufgesetzt und die Montagestelle für den Reflektor markiert und schliesslich der Reflektor montiert, oder es wird zuerst der Reflektor montiert und dann der Melder und anschliessend der Melder mit Hilfe des Installationswerkzeugs auf den Reflektor ausgerichtet. Das sind einfache Operationen, die nur eine Person erfordern.In the method according to the invention, therefore, either the detector is mounted first, then the Installation tool placed on the transmitter / receiver part and the mounting point for the Reflector marks and finally the reflector mounted, or it will be the reflector first and then the detector and then the detector with the help of the installation tool aligned with the reflector. These are simple operations that only one person does require.

Die Erfindung betrifft weiter ein Werkzeug zur Durchführung des genannten Verfahrens nach den Merkmalen von Anspruch 6. In den abhängigen Ansprüchen 7 bis 10 sind vorteilhafte Ausgestaltungen und Weiterbildungen des erfindungsgemässen Werkzeugs angegeben.The invention further relates to a tool for carrying out said method the features of claim 6.

Das erfindungsgemässe Werkzeug zur Durchführung des Verfahrens ist ein Installationsdeckel, der einen Laser enthält und an Stelle des Originaldeckels auf den Melder aufgesetzt wird. Der Laser zielt, vertikal und horizontal ausgerichtet, in die gleiche Richtung wie der im Werk abgeglichene Melder.The inventive tool for carrying out the method is an installation cover, contains a laser and is placed on the detector instead of the original cover.

Fig. 2
eine schematische Darstellung des Sender-/Empfängerteils eines linearen Rauchmelders mit einem erfindungsgemässen Werkzeug.
In the following the invention with reference to an embodiment and the drawings will be explained in more detail; it shows:
Fig. 1
a block diagram of a linear smoke detector; and
Fig. 2
a schematic representation of the transmitter / receiver part of a linear smoke detector with a novel tool.

Der in Fig. 1 dargestellte Rauchmelder funktioniert nach dem Prinzip der Extinktion, also der Abschwächung eines Lichtstrahls durch in diesen eintretenden Rauch. Der Rauchmelder besteht darstellungsgemäss aus einem nachfolgend als Melder M bezeichneten Sender-/Empfängerteil mit einem Lichtsender 1, einem neben dem Lichtsender 1 angeordneten Lichtempfänger 2 und einer mikroprozessorgesteuerten Steuer- und Auswerteelektronik 3, und aus einem dem Melder M gegenüber liegenden Reflektor 4. Der Melder M ist im Werk so abgeglichen, dass der vom Lichtsender ausgesandte Lichtstrahl horizontal und vertikal ausgerichtet ist.The smoke detector shown in Fig. 1 works on the principle of extinction, so the Attenuation of a ray of light by entering this smoke. The smoke detector is made according to the representation of a hereinafter referred to as detector M transmitter / receiver part with a light transmitter 1, a light receiver arranged next to the light receiver 1 2 and a microprocessor-controlled control and evaluation 3, and from a the Detector M opposite reflector 4. The detector M is adjusted in the factory so that the from the light emitter emitted light beam is aligned horizontally and vertically.

Der Lichtsender 1 sendet einen modulierten Infrarotstrahl zum Reflektor 4, der den auftreffenden Strahl auf den Lichtempfänger 2 reflektiert. Sobald Rauchpartikel in den Strahlengang gelangen, wird einerseits ein Teil des Infrarotstrahls von diesen Partikeln absorbiert, und andererseits ein anderer Teil des Infrarotstrahls von den Partikeln reflektiert oder an ihnen gestreut. Beide Effekte bewirken eine Abschwächung des auf dem Lichtempfänger 2 auftreffenden Lichts. Lichtsender 1 und Lichtempfänger 2 bilden zusammen mit der Elektronik 3 den so genannten Meldereinsatz 6 (siehe Fig. 2). The light emitter 1 transmits a modulated infrared beam to the reflector 4, which detects the impinging Beam reflected on the light receiver 2. Once smoke particles in the beam path arrive, on the one hand a part of the infrared beam is absorbed by these particles, and on the other hand, another part of the infrared ray is reflected by or from the particles scattered. Both effects cause a weakening of the incident on the light receiver 2 Light. Light transmitter 1 and light receiver 2 together with the electronics 3 so said detector insert 6 (see Fig. 2).

Der Reflektor 4 ist beispielsweise ein retroreflektierendes Prisma von der Gestalt einer geraden Pyramide, deren Seitenflächen durch gleichschenkelige, rechtwinkelige Dreiecke gebildet sind. Ein solcher Reflektor wirkt auf das auftreffende Licht als Polarisator und dreht dessen Schwingungsebene um ungefähr 90°, wobei dieser Winkel in einem gewissen Bereich streuen kann.The reflector 4 is, for example, a retroreflective prism of the shape of a straight one Pyramid whose sides are formed by isosceles, right-angled triangles. Such a reflector acts on the incident light as a polarizer and rotates its oscillation plane by about 90 °, which angle can scatter in a certain range.

Der dargestellte Rauchmelder wird insbesondere zur Überwachung von grossen Lager- und Fabrikationshallen, Räumen mit komplexen Deckenkonstruktionen oder kunsthistorisch wertvollen Decken, überdachten Innenhöfen, Atriumgebäuden oder Empfangshallen verwendet, wobei die Distanz zwischen dem Sender-/Empfangsteil M und dem Reflektor 4 zwischen 5 und 100 m und in Ausnahmefällen sogar mehr als 100 m betragen kann.The smoke detector shown is used in particular for monitoring large storage and Production halls, rooms with complex ceiling constructions or art-historically valuable ones Ceilings, covered courtyards, atrium buildings or reception halls used, wherein the distance between the transmitter / receiver part M and the reflector 4 between 5 and 100 m and in exceptional cases even more than 100 m.

Der in Fig. 2 dargestellte Melder M besteht in bekannter Weise aus dem in einem Sockel 5 befestigten Meldereinsatz 6 mit der gesamten Optik und Elektronik, von der sich auch ein Teil im Sockel 5 befinden kann, sowie aus einem Deckel 7, der zur Abdeckung des Meldereinsatzes 6 dient. Der Deckel ist im wesentlichen ein Tageslichtfilter; er wird über den montierten und eingestellten Meldereinsatz 6 gestülpt und mit Schrauben befestigt. Der Sockel 5 ist beispielsweise einstellbar ausgebildet, so dass die Neigung des Melders M und die damit die Achse des vom Lichtsender 1 ausgesandten Lichtstrahls verstellbar ist. Diese Art von Verstellung des Melders M wird nachfolgend als Grobjustierung bezeichnet. Ausserdem sind im oder am Melder M Mittel zur Ausrichtung der Optik von Lichtsender 1 und Lichtempfänger 2 vorgesehen; eine Ausrichtung der Optik mittels dieser Mittel wird nachfolgend als Feinjustierung bezeichnet.The detector M shown in Fig. 2 consists in a known manner from that in a base. 5 fixed detector insert 6 with the entire optics and electronics, of which also part may be located in the base 5, as well as a lid 7, which covers the detector insert 6 serves. The lid is essentially a daylight filter; he is over the mounted and adjusted detector insert 6 and fastened with screws. The base 5 is for example adjustable, so that the inclination of the detector M and thus the axis of the detector from the light emitter 1 emitted light beam is adjustable. This kind of adjustment of the Detector M is referred to below as coarse adjustment. In addition, are in or at the detector M means for aligning the optics of light emitter 1 and light receiver 2 are provided; a Orientation of the optics by means of this means is referred to as fine adjustment.

Zur Installation/Inbetriebnahme des Sender-/Empfängerteils M wird der Melderdeckel 6 abgenommen und durch ein Werkzeug für die gegenseitige Ausrichtung von Melder M und Reflektor 4 ersetzt. Dieses Werkzeug ist darstellungsgemäss ein Installationsdeckel 8 mit einer vorzugsweise durch einen Laser 9 gebildeten Lichtquelle für die Aussendung von gebündeltem Licht. Der Laser 9 ist am oder im Installationsdeckel 8 so montiert, dass er mit dem Lichtsender 1 (Fig. 1) des Melders M fluchtet und somit in die gleich Richtung "zielt" wie der Lichtsender 1. Selbstverständlich darf der Laser 9 den Lichtstrahl des Lichtsenders 1 nicht stören. Die Stromversorgung des Lasers 9 erfolgt entweder via Meldersockel 5 über das Netz oder über eine im Installationsdeckel 8 eingebaute Batterie.For installation / commissioning of the transmitter / receiver part M of the detector cover 6 is removed and a tool for the mutual alignment of detector M and reflector 4 replaced. This tool is shown in accordance with an installation cover 8 with a preferably by a laser 9 formed light source for the emission of concentrated light. The laser 9 is mounted on or in the installation cover 8 so that it is connected to the light emitter 1 (Fig. 1) of the detector M is aligned and thus "aims" in the same direction as the light transmitter 1. Of course the laser 9 must not disturb the light beam of the light emitter 1. The power supply of the laser 9 takes place either via the detector base 5 via the network or via an im Installation cover 8 built-in battery.

Der vom Laser 9 ausgesandte Lichtstrahl markiert an der dem Melder M gegenüberliegenden Wand die Auftreffstelle des vom Lichtsender 1 ausgesandten Lichtstrahls und somit die Stelle, an welcher der Reflektor 4 (Fig. 1) montiert werden muss.The light beam emitted by the laser 9 marks at the detector M opposite Wall the point of impact of the light beam emitted by the light emitter 1 and thus the location at which the reflector 4 (Fig. 1) must be mounted.

Die Installation/Inbetriebnahme des linearen Rauchmelders kann auf folgende Arten erfolgen:

  • Der Melder M ist im Sockel 5 montiert und die Montage des Reflektors 4 ist noch nicht erfolgt. In diesem Fall markiert der Laserstrahl des Lasers 9 an der gegenüber liegenden Wand die Stelle, wo der Reflektor 4 montiert werden muss. Im Melder M ist anschliessend nur noch eine Feinjustierung notwendig.
  • Die Montagestelle des Reflektors 4 ist definiert, beispielsweise ist der Reflektor 4 schon montiert, und der Melder M ist auf den Reflektor 4 auszurichten. Dann wird der Melder M mit dem aufgesetzten Installationsdeckel 8 so lange auf der Wand verschoben bis der Laserstrahl auf den Reflektor 4 oder dessen Montagestelle trifft, so dass die Montagestelle des Melders M markiert und anschliessend der Melder M montiert werden kann. Nach der Montage ist am Melder M nur noch eine Feinjustierung nötig. Voraussetzung für diese Art der Installation ist eine möglichst glatte Wand.
  • Sowohl die Montagestelle des Reflektors 4 als auch diejenige des Melders M ist definiert, letztere dadurch, dass der Sockel 5 bereits montiert ist. Der Laserstrahl des Lasers 9 liefert einen Anhaltspunkt, wie gross die Abweichung zwischen Melder M und Reflektor 4 ist und erleichtert die Grobjustierung des Melders M. Es ist auch möglich, diese Abweichung auszumessen, aus einer Tabelle anhand der Abweichung und der Distanz zwischen Melder M und Reflektor 4 eine Verstellgrösse auszulesen und eine am Melder vorgesehene Verstelleinrichtung entsprechend zu verstellen. In beiden Fällen ist anschliessend nur noch eine Feinjustierung notwendig.
  • Sowohl die Montagestelle des Reflektors 4 als auch diejenige des Melders M ist definiert; der Sockel 5 ist einstellbar. Der Laserpunkt wird mit dem einstellbaren Sockel 5 so positioniert, dass er den Reflektor 4 trifft. Am Melder M ist anschliessend nur noch eine Feinjustierung erforderlich.
The installation / commissioning of the linear smoke detector can be carried out in the following ways:
  • The detector M is mounted in the base 5 and the installation of the reflector 4 is not yet done. In this case, the laser beam of the laser 9 on the opposite wall marks the point where the reflector 4 must be mounted. In the detector M, only a fine adjustment is necessary afterwards.
  • The mounting position of the reflector 4 is defined, for example, the reflector 4 is already mounted, and the detector M is to be aligned with the reflector 4. Then the detector M with the attached installation cover 8 so long on the wall until the laser beam strikes the reflector 4 or its mounting point, so that marks the mounting point of the detector M and then the detector M can be mounted. After installation, only a fine adjustment is required at detector M. Prerequisite for this type of installation is the smoothest possible wall.
  • Both the mounting position of the reflector 4 and that of the detector M is defined, the latter in that the base 5 is already mounted. The laser beam of the laser 9 provides an indication of how large the deviation between detector M and reflector 4 and facilitates the coarse adjustment of the detector M. It is also possible to measure this deviation, from a table based on the deviation and the distance between detector M and Reflector 4 read an adjustment size and to adjust a provided on the detector adjusting accordingly. In both cases, then only a fine adjustment is necessary.
  • Both the mounting position of the reflector 4 and that of the detector M is defined; the base 5 is adjustable. The laser spot is positioned with the adjustable base 5 so that it hits the reflector 4. The detector M is then only required a fine adjustment.

Nach erfolgter Installation wird der Installationsdeckel 8 vom Melder M abgenommen und durch den Melderdeckel 7 ersetzt, womit der lineare Rauchmelder betriebsbereit ist.After installation, the installation cover 8 is removed from the detector M and through replaced the detector cover 7, with which the linear smoke detector is ready for use.

Der Installationsdeckel 8 ist auch bei Applikationsproblemen hilfreich. Wenn solche Probleme (beispielsweise Gebäudeverwindungen, Vibrationen, undefinierte Abdeckungen des Lichtstrahls, usw.) auftreten, wird der Installationsdeckel 8 montiert und der Laserpunkt in kritischen Phasen beobachtet. Dadurch kann ein mögliches Applikationsproblem bestätigt oder ausgeschlossen werden.The installation lid 8 is also helpful with application problems. If such problems (eg building distortions, vibrations, undefined covers of the light beam, etc.), the installation cover 8 is mounted and the laser spot in critical Observed phases. This can confirm or exclude a possible application problem become.
