Definitions

  • the invention relates to a connection device for automatic fire detectors, which has a detector base to be connected to a detector.
  • Automatic fire detectors generally have a base in which the actual detector is inserted and anchored, for example, with a bayonet catch.
  • a protective sleeve is used, e.g. can be made of plastic material, partly pushed over the detector and over the base and locked with one or two screws.
  • the detector base is installed in an inlet box installed in the ceiling. When the detector is inserted, the base and the inlet socket are covered with a rosette and also fastened with screws.
  • a connection device for fire detectors is known from European Patent Application No. 014251. There, a connection device is described in which a connection between a base part and a detector insert of a fire detector is established via electrical and mechanical connection elements. The base part and the detector part are matched to one another, so that another detector insert cannot be connected to the known base part.
  • Newer and more modern detectors are now more functional, but also smaller than known detectors. They have a smaller diameter and a lower overall height, so that smaller and differently designed detector bases or detector holders are also required.
  • every detector location would have to be converted for detectors of newer and more modern designs. This means that the old detector bases would have to be removed and new detector bases installed.
  • this entails the risk that the existing installation wires can easily be damaged and a new, complex and costly new installation may then be necessary.
  • dismantling the old detector base and fitting the new detector base is very complex.
  • a connecting device of the type mentioned at the outset in such a way that it can be fitted and attached to existing detector bases with little effort and that a detector holder for different detector types or detector inserts of a more recent type is mounted thereon can be.
  • the connecting device should be mass-produced in a simple manner and be assembled in a few simple steps.
  • the adapter according to the invention is designed as a circular plastic injection molded part and has, for example, two fastening screws which are inserted through fastening openings arranged in the adapter such that the adapter can be quickly mounted on the old, existing detector base in the thread there.
  • the adapter has one or more holding devices for fastening elements, e.g. Screws with which a detector holder for modern automatic fire detectors can be screwed on.
  • This receiving device is expediently arranged on the adapter in accordance with the fastening holes of the detector detection.
  • This receiving device can be designed in a simple manner as a cylindrical projection with a centrally arranged bore into which a screw with a cutting thread can be screwed in for mounting the detector holder.
  • the adapter In order to electrically connect the new detector socket to the old detector base, the adapter has a breakthrough through which the connecting lines (cable pieces) provided with cable lugs can be inserted and screwed to the screw terminals of the detector base or the detector socket.
  • an automatic fire detector 3 is shown, which is mounted with its detector 13 on the new adapter 1 and this on the old detector base 4.
  • the adapter 1 and the detector holder 13 are shown partially torn open, so that the base 4 of known detectors, the adapter 1 and the detector holder 13 are shown partly in section.
  • the old detector base 4 is attached to the ceiling 2.
  • the plastered installation lines 5 are led out of the ceiling 2 and generally through seals 4b in the detector base 4 to the screw terminals 7 and connected there.
  • the base 4 has two screw threads 4a, which are embedded in the base 4. In Fig. 1, only a screw thread, on the left side, is indicated by 4a. In this screw thread 4a, after the old design detector was inserted into the base and the protective sleeve mentioned at the beginning was attached, the protective sleeve was fastened with one or two screws.
  • the screw thread 4a is used for fastening the adapter 1 according to the innovation.
  • the circular disc-shaped adapter 1 has a conical shell 1a formed on the outer edge, which lies on the ceiling 2 and surrounds the base 4.
  • the diameter of the conical jacket 1 of the adapter 1 is larger in the area of the ceiling 2 than the diameter of the detector base 4.
  • a cylindrical jacket 12a is formed diametrically opposite each other perpendicular to the circular surface of the adapter 1.
  • Fig. 1 only the left cylinder jacket 12a is shown.
  • Inside the cylinder is e.g. captive, screw 12, which is inserted through the mounting opening 12b.
  • the adapter 1 is fastened on the base 4 in the screw thread 4a with two screws 12.
  • the socket 13 for newer detector types 3 is fastened on the adapter 1 with two screws 15.
  • the diameter of the circular disc-shaped adapter body 1 is larger than the diameter of the detector holder 13.
  • only the left screw 15 for fastening the detector holder 13 on the adapter 1 is shown.
  • perpendicular to the adapter circular surface 1, towards the ceiling side 2 a cylindrical projection 16 with a centrally arranged bore 16a is attached to the adapter 1 and a fastening hole 15a in the detector socket 13.
  • the two screws 15 can be self-tapping screws which cut into the bore 16a of the adapter 1, so that no additional thread in the adapter 1 or a separate nut is required.
  • the adapter 1 has an opening 11 through which prefabricated cable pieces 9 (only one shown) are passed in order to establish the electrical connection from the screw terminals 7 of the detector base 4 to the screw terminals 14 of the detector socket 13. Cable lugs 8 and 9a are attached to the cable ends for faster installation.
  • the detector insert 3 is inserted into the detector holder 13 in a manner known per se.
  • FIG. 2 an automatic fire detector with an adapter 1 ' for flush mounting is shown.
  • the inlet box 6 a known detector base 4 'for inlet boxes is shown.
  • the mounting options for two detector sockets 13 and 13 ' for different detector types are shown in FIG. 2.
  • the adapter 1 ' according to the innovation has a different construction from the adapter 1 according to FIG. 1.
  • the adapter 1 ' is a circular disk-shaped molded part with a diameter that is larger than the diameter of the adapter 1 for the surface-mounted version.
  • the diameter of the adapter 1 ' is larger than the diameter of the inlet socket 6, so that it is covered by the adapter 1'.
  • the cone jacket (1a) is missing.
  • annular bead 1 b is formed on the ceiling side 2, so that the adapter 1' rests on the ceiling 2.
  • the projection 16 with the bore 16a corresponds to the projection of the adapter 1 according to FIG. 1 and is congruent with the mounting hole 15a in the detector socket 13 or 13 'for example for the detector 3.
  • the self-tapping screw 15 for fastening the detector socket 13 or 13 ' shown on the adapter 1'.
  • the adapter 1 ' also has an opening 11 for the connecting cable 9. These are fastened to the screw terminals 14 of the detector socket 13 or 13 'with the cable lugs 9a.
  • the fastening device for the adapter 1 'on the base 4' is designed somewhat differently from the first exemplary embodiment (FIG. 1).
  • Two bores 12b are arranged in the adapter 1 '. Only one is shown.
  • the adapter 1 ' is fastened to the base 4' with fastening screws 12.
  • a threaded plate 12c is to be inserted into the base 4 'on the existing fastening device 4'a.
  • 2 shows both a reporting insert 3 of a newer type and a reporting insert 3 'of the old type. This is for illustration only.
  • Either a detector socket 13 for the detector insert 3 or a detector socket 13 ' is provided for a detector insert of a different type, not shown here.
  • an existing fire alarm system can be easily and quickly converted without having to provide a new installation. It is also not necessary to replace the original detector base. This avoids the risk of damage to the existing wiring. All that needs to be done is to mount the adapter according to the innovation on the existing base and then use simple means to mount the socket for the various new detector types. It is only necessary to screw connecting cables that are passed through an opening in the adapter to the screw terminals of the old base and to connect them to the screw terminals of the new detector. This has the advantage that an existing fire alarm system can be converted to a modern alarm system in which modern detectors and a more powerful control center can be used.
