Definitions

  • 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.
  • 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.
  • 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.
  • 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.
  • the optics 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.
  • 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.
  • 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.
  • the invention further relates to a tool for carrying out said method the features of claim 6.
  • a tool for carrying out said method the features of claim 6.
  • the dependent claims 7 to 10 are advantageous embodiments and further developments of the inventive tool indicated.
  • 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.
  • the laser aims vertically and horizontally in the same direction as the one in the factory matched detectors.
  • 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.
  • the light emitter 1 transmits a modulated infrared beam to the reflector 4, which detects the impinging Beam reflected on the light receiver 2.
  • the reflector 4 detects the impinging Beam reflected on the light receiver 2.
  • 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.
  • 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.
  • 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.
  • fine adjustment 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.
  • a tool for the mutual alignment of detector M and reflector 4 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • problems eg building distortions, vibrations, undefined covers of the light beam, etc.
