  • the present invention relates to a hazard detection system with a central, a plurality of danger detectors connected to these and with a control unit for operation the hazard detector, the control unit and the hazard detector for two-way communication are trained.
  • detector exchangers and detector testers are known. With the detector exchangers can fire detectors during commissioning and revision by a push and turn movement inserted and removed from the detector base.
  • the detector exchanger contains a so-called adapter flexibly attached to a pipe socket, with which the detector can be fixed with a wrench, and extension tubes, which enable a detector exchange up to a height of about 7 meters.
  • the detector inspector can either contain a can with a test gas or a hot air generator (see see for example US-A-3,693,401 and the detector tester CERBERUS DZ1191 and CERBERUS RE6 / RE6T from Siemens Building Technologies AG (CERBERUS - registered Trademark of Siemens Building Technologies AG).
  • detector exchangers / detector testers with a combined picking / testing / picking head known in which light pulses into the measuring chamber of a stray light detector to be tested are sent and the detector's detector is checked for these light pulses (See, for example, EP-A-0 636 266, EP-A-0 910 055 and the detector exchanger / detector tester CERBERUS DZ1193 from Siemens Building Technologies AG).
  • the control panel Whenever a detector is removed from its base, the control panel must first receive a message that the detector in question is not functioning, and must do so be informed that an exchange has taken place. It means that the operator concerned before and after the detector exchange during maintenance work had to go to the headquarters and enter the necessary information there, they weighed Maintenance work on the detectors themselves. The same applies to the review of Report where the control center must also be informed accordingly for the function test does not raise an alarm. It is obvious that this procedure is especially for larger ones Plants that are cumbersome and complex.
  • the invention is now intended to provide a hazard detection system of the type mentioned at the outset which maintenance and maintenance work on the detectors is as simple and easy as possible can be carried out efficiently.
  • the hazard detectors are used as connection nodes trained for communication between the control unit and the control center.
  • the control unit is a mobile terminal that can be sent to the control center via any hazard detector can be connected and communicate with it. This allows the exchange and when checking detectors of the control center, information to be supplied directly to the relevant detectors themselves and it is no longer necessary that move the operator to the headquarters to enter this information got to.
  • a suitable operating unit can be, for example, an operating module for a hazard detector of the type described in EP-A-0 872 817, a device for remote adjustment of Parameters of a sensor of the type described in US-A-4,704,607 or a remote control of the type described in EP-A-1 158 840. All of these control units is common that they have an interface for bidirectional data communication with the have relevant hazard detectors, this data communication for querying and / or Remote setting of the detector is used.
  • the control unit can also be in one Detector exchangers and / or detector testers of the type mentioned at the beginning can be installed and Form part of this.
  • the fire alarm system shown in Fig. 1 schematically shows a control center 1 and various detector lines connected to it, a detector line M 1 with manual hazard detectors 2, a detector line M 2 with special detectors, as shown a flame detector 3 and a line extinction detector 4, and a detector line M 3
  • So-called point detectors 5 sintered light smoke detectors, temperature, fire gas or multi-criteria detectors attached to the ceiling, as well as an operating unit 6 for on-site operation of the various detectors.
  • the representation is not to be understood as meaning that each detector type is connected to the control center 1 via its own detector line; it is rather the case that different detector types are connected to a common detector line.
  • Suitable stray light smoke detectors are described, for example, in EP-A-0 636 266 and EP-A-0 821 330, a line extinction detector in European patent application No. 01 114 103.3 and a flame detector in EP-A-0 718 814.
  • control unit 6 is to be understood generally. This can be a module act as a remote control for data communication with the detectors or a Tool for changing / inserting or checking detectors, which at the same time is usable for data communication.
  • the control unit 6 shown in FIG. 1 is a Tool of the latter type and consists of a so-called detector tester and / or detector picker (hereinafter referred to as test picker 7), this is a tool for checking the function and / or for inserting / removing a detector into / from a base, and from a terminal 8 for the input and display of data.
  • the test picker 7 consists essentially of a test / picking head 9 which is on a short Tube 10 is articulated, a test electronics arranged in the test / picking head 9, one Power supply, a function display and a main switch.
  • a test / picking head 9 and in point detector 5 there is an interface for bidirectional data communication between the test / picking head 9 and detector 5 are provided. This interface is shown in Fig. 2.
  • the tube 10 can be extended telescopically by extension tubes (not shown) become.
  • Suitable test pickers 7, but without the communication interface mentioned, are described in EP-A-0 636 266 and EP-A-0 971 329.
  • the communication interface of a detector 5, designated by the reference symbol KM is shown in the left half and the communication interface, designated by the reference symbol MB, of the test / picking head 9, which is separated from one another by a dashed line A symbolizing the transmission medium are.
  • Both communication interfaces KM and KB each have an optical and an inductive channel KM o , KM i and KB o , KB i .
  • the optical channel KM o the detector communications interface KM contains a 13.
  • the optical channel KB o visible from the outside through a LED alarm indicator formed 11 for visual display of alarms and faults and a printer connected to a microprocessor 12 of the detector LED driver of the test / Picking head communication interface KB contains a photodiode 14, an amplifier 15 connected to it and a pulse shaper 16 connected downstream of the amplifier, the output of which is connected to a microprocessor 17 of the operating unit.
  • the inductive channel KB i of the test / picking head communication interface KB contains an oscillator 18 controlled by the microprocessor 17 and an inductor 19 which is formed, for example, by a wire loop.
  • the inductive channel KM i of the detector communication interface KM contains a resonance circuit 20, a demodulator 21 connected downstream thereof and a pulse shaper 22 connected to the demodulator, the output of which is connected to the microprocessor 12.
  • the wire loop 19 is inserted into the testing / picking head 9, which is pushed onto the detector 5 containing the resonant circuit 20 for each transmission process.
  • the photodiode 14 is arranged in the test / picking head 9 such that the light emitted by the alarm indicator 11 is applied to it.
  • the communication interface can be designed for communication in the high-frequency range, preferably according to the Bluetooth standard, or in the infrared range, preferably according to the IrDA standard.
  • the terminal 8 could be fixed on the pipe 10 or on an extension pipe be designed so that an operator simultaneously the test / picking head 9 over the to keep operated detector 5 and can operate the terminal 8, but what from one certain room height is difficult. For this reason, this is for example a handheld or a PDA (Personal Digital Assistant) terminal 8 is not on the test picker 7 attached but removed from it and it is between the terminal 8 and the test / picking head 9 a communication link, for example according to the IrDA or the Bluetooth standard.
  • PDA Personal Digital Assistant
  • the test / picking head 9 is opened pushed the detector 5 and positioned on it. Then the detector sits down when prompted through the module communication interface KB into a data transfer mode.
  • the Data go from the detector 5 to the test picker 7, are stored there and as rough information (Go / No Go) is displayed so that this information can also be read from a distance of 7 m.
  • the test picker 7 is set down by the detector 5 and the details of the stored data can be accessed through Terminal 8 if this information is desired.
  • the data transfer from the terminal 8 to the detector 5 is analog, but also one Intermediate storage in the test picker 7 takes place. It is also a data transfer in both Directions possible. Data entered into Terminal 8 can of course be used remain stored in the test picker 7 and used several times on different detectors become.
  • the detector can also put itself into data transfer mode if the Test picker 7 authenticated or identified as a permitted control unit for data transmission. This authentication can take place using special codes or cryptological methods.
  • the detector 5 can be detected and operated stored data, for example near-alarms and the like, to the terminal 8 send, and on the other hand, data or commands, such as Instructions related to service work or parameters are transferred. Software updates may also be carried out in data transfer mode.
  • the data transfer mode also for establishing a bidirectional connection between the Control unit 6 and the control center 1 can be used via the respective detector by For example, the control center is informed that service work has been carried out on the detector or the control panel is asked to switch the detector to a corresponding mode switch or write the data sent to the detector.
  • the indirect transfer of data or commands from the control unit via the control center to the detector has the advantage over the possible direct transfer that the Central is informed on the one hand about changes made in the detector and on the other hand exercise a filter function and are not activated for the relevant detector Can prevent changes.
  • the system can be operated from any location in the building equipped with a detector the time required for commissioning and service work is reduced. Furthermore operating errors can be avoided by changing the mode Detector does not have to be selected from a list (risk of selecting an incorrect entry or incorrect list), but is designated directly on site.
  • a fire alarm system usually contains not only on the Ceiling-mounted point detector 5, for which the test picker 7 was originally intended was, but also special detectors, such as manual hazard detectors 2, flame detectors 3 and mononextin Needlessmelder 4, which are largely attached to the wall.
  • this detector is not a special tool for assembly / disassembly or detector testing in Use, but these detectors must also be periodically tested on site, whereby here, too, before and after the test, the head office must enter that the detector in question is / was tested and therefore in test mode or normal Operating state is to be set.
  • the control unit 6 is designed such that it can also be used for the Operation of the special detectors mentioned and other modules can be used.
  • Fig. 3 is this multifunctionality of the control unit 6 in connection with a manual hazard detector 2 shown in Fig. 4 in connection with a line extinction detector 4, a acoustic alarm device 23 and with a so-called line module 24.
  • Line modules are, for example, input / output modules for switching on fire detectors from another Type to an existing system, or to switch on work or rest contacts or for the decentralized control of technical equipment such as fire doors, ventilation, Air conditioners, and the like.
  • Line modules are the so-called line separators, which ensure that in the event of a short circuit on a detector bus, not the whole Bus fails, but only the defective part of a line is isolated.
  • line blocks have usually a flat, box-like shape and are often stacked side by side, so that there are certain restrictions regarding external accessibility.
  • manual hazard detectors are at a height of around 150 cm on the wall assembled and have the shape of an approximately square, flat box with a Diagonal, which corresponds approximately to the diameter of a point detector 5. That is it possible to hold the test picker 7 horizontally and to place it on the manual hazard detector 2. Since an extension of the tube 10 is not necessary, the terminal 8 is advantageous attached to the tube 10, for example with an elastic clip.
  • the test / picking head 9 is with a module communication interface KB and the manual hazard detector with a detector communication interface KM equipped of the type shown in Fig. 2.
  • test picker 7 Because the test picker 7 is easy to handle with the short tube 10, there is no need for data communication to carry out in two steps. With such an arrangement, the distance of the wireless Communication greater than with the point detector. This situation is recognized by the test picker 7 (Limit switch), whereupon transmission power and reception sensitivity are increased.
  • the line extinction detector 4 shown in FIG. 4 has a metallically shielded housing and is therefore rather not for a communication interface of the type shown in FIG. 2 suitable.
  • the acoustic alarm device 23 has the shape a round box, possibly with a curved base, and can therefore be used with a detector communication interface KM (Fig. 2) are equipped.
  • Test picker 7 Communication between Test picker 7 and line extinction detector 4 as well as the line block 24 is carried out via a Plug cable 25, the plug of which are designed such that they are also arranged in stacks Line blocks 24 can be easily inserted.
  • the is used for the line extinction detector Test pickers also help as an installation aid by checking the quality and distance of the back mirrored optical signal displayed online and thereby adjusting the housing is simplified.
