Definitions

  • the invention relates to a method for detector identification in a hazard alarm system, in particular fire alarm system, according to the preamble of claim 1 and to an arrangement for performing the method.
  • Hazard detection systems with detector identification are known per se. They generally require specially designed detectors, the addresses of which must be encoded in the individual detector for identification. Corresponding evaluation devices in the control center can then determine and display the address of the concerned meider from the code transmitted or queried by the detector.
  • a signaling system which has a control center and at least one signaling line with detectors connected in parallel.
  • each detector has a decoder for a pulse of different lengths assigned to it by the control center in the form of line voltage sent address and an alarm suppression circuit arranged.
  • the alarm signal is suppressed when the first address pulse is received by the alarming detector and, if the address of the detector concerned is correctly decoded, the alarm signal is returned to the signaling line.
  • the known signaling system has the disadvantage, however, that the encoder causes an additional current requirement because the encoder must also be kept ready for operation in the idle state so that the alarm can be triggered via it if the detector itself does not do so due to the superimposed interference voltage and its alarm suppression circuit Location is
  • the power supply of the control center is generally limited, not all alarming detectors, if several detectors of one zone give alarm at the same time, the associated alarm display on the detector can be supplied with sufficient power. A reliable alarm display on the detectors is then not guaranteed
  • each detector has an addressing module with which an alarm signal from a triggering detector is initially given to the alarm line at a time-limited time. After that, the message line is free for the address query. The detector does not require any additional electricity until the message is received.
  • the addressing block has determined the address of its assigned detector from the pulse sequence of the query pulses. i.e. if the queried detector address matches the detector's set address, the detector in question releases its alarm again in the form of a sudden increase in current.
  • the detectors If several detectors have given an alarm on a line, they are triggered one after the other so that the limited current available on a signaling line is sufficient in any case to ensure a reliable alarm display on the relevant detector, which is even sufficient in order to supply an additional Meldar display located on the relevant detector with sufficient energy.
  • the sudden increase in current is detected with an evaluation device, and the respective address of the alarming detector is determined and displayed from the number of query pulses up to the increase in current.
  • the interrogation pulses are expediently formed by pulse-wise lowering of the line voltage. These counting pulses given by the center to the signaling line have a constant duration in a simple manner. These counting pulses are counted in the addressing module of the detector and when the set counter status is reached, the alarm criterion is given to the signaling line.
  • An expedient arrangement for carrying out the method has an addressing module, which is assigned to each detector.
  • a current limiter is arranged between the actual detector (sensor) and the signaling line, which limits the current when the detector gives an alarm so that a direct current increase does not occur directly at the Message line can be generated.
  • the alarm output for the duration of the timer is limited via an alarm timer, which is connected downstream of the detector of the detector on the reporting line
  • FIG. 1 shows an addressing module for identifying an alarm-triggering detector and FIGS. 2 and 3 show pulse diagrams for detector identification.
  • a detector M1 and an addressing block AB on the signal line ML is shown.
  • the message line ML leads on the one hand to the central station Z and on the other hand to further detectors M2 or addressing blocks AB.
  • the detector M1 is connected to the signal line ML via the voltage limiter SB.
  • a timer ZG and a counter ZA are also connected downstream of the detector.
  • the timer ZG is controlled directly by the detector M1 when it gives an alarm and for the duration (TV) of the timer ZG via the transistor TR1 and the Zener diode Z1, both of which are connected in series on the signal line ML, the alarm message (AL ML ) to the ML reporting line.
  • This alarm message is recognized in the control center Z as an alarm of the message line ML because a voltage drop ULA is generated with the alarm triggering detector.
  • the counter ZA has at its reset input R an RC element R4, C1, which is connected as a series connection to the signaling line. Via this RC element, the counter ZA is reset before the detector is queried.
  • the query impulses from the control center reach the clock input T of the counter ZA via the signal line and the diode D1.
  • the counter ZA has outputs A1 to An and depending on the soft output, the downstream controllable switching element, the transistor TR2, is connected, the transistor TR2 turns on.
  • the transistor TR2 is connected to the message line ML via the message display MA and a resistor R7.
  • a second Zener diode Z2 is arranged parallel to the detector display MA and the resistor. If the interrogation pulse matches the set counter reading, the Zener diode Z2 applies a specific voltage value (ULA Mi) to the line as a detector alarm (AL Mi).
  • An additional detector display MAZ can also be assigned to the detector M1 or the addressing module AB, as shown in the drawing. The method according to the invention is briefly explained again with reference to FIGS. 2 and 3.
  • FIG. 2 shows a pulse diagram of the line voltage UL and FIG. 3 shows a pulse diagram of the line current IL. If the signal line is at rest, there is a quiescent voltage ULR, generally 20 volts, on the signal line (ML).
  • AL alarm message
  • the alarming detector causes an alarm message (AL ML) in the form of a voltage dip ULA ML on the message line for a specific time TV, which corresponds to the duration of the timer (ZG).
  • the message line is free for the query impulses that are sent from the control center.
  • TP short pause
  • ILA Mi current limit
  • the counters of the individual detectors are reset to the initial position.
  • the interrogation pulses AFIP in the form of counting pulses with the same duration are given to the signal line by a pulse-wise lowering of the line rest voltage ULR.
  • the third detector (M3) is the alarm-triggering detector
  • the third counting pulse causes the alarm message AL M3 of the third detector at time t5. Since the control center the pulse sequence of the query pulses in the event of an alarm message for a specific
