Definitions

the invention relates to a method for alarm signaling, in which after a first response of a detector connected to a signal center, the latter is reset for the first time by the signal center, and furthermore, at a predetermined time after the detector responds in the signal center, two test times with predetermined different Running times are started and an alarm signal is only forwarded after the detector has responded again at least once and in which an alarm signal is finally forwarded if the detector responds with a shorter duration after the test time has elapsed and with a longer duration before the test time has elapsed, and a device to apply this procedure.
Such methods and devices are suitable for signaling various types of dangerous states by means of suitable detectors which respond to the relevant state.
An important application is, for example, the signaling of a fire outbreak by means of a fire phenomenon, e.g. Smoke, fire aerosol, fire gases, flame radiation, temperature variations, etc. of appealing fire detectors or the signaling of the presence of flammable and / or toxic gases.
fire alarm systems should signal a fire at the earliest possible stage and trigger appropriate measures to combat it.
highly sensitive automatic fire detectors which already react to the phenomena that occur in the early stages of a fire, such as ionization smoke detectors or optical smoke detectors. If such fire detectors, however, with the highest possible sensitivity, there is a risk that an alarm signal will be triggered by disturbance variables, even though there is no dangerous state, i.e. no fire, and that such a false or false alarm will unnecessarily trigger expensive fire-fighting measures, e.g. the fire brigade or a fire extinguishing system is put into operation.
Fire detection methods such as those in CH 623 154 or the Cerberus brochure FP 198: M. Ruggli / F. Datwyler's "Cerberus alarm concept" are described by involving people in the decision-making process.
the alarm signal triggered by a fire detector is then only forwarded if no control personnel are available, or if the signal is not acknowledged within a certain control period, and if, within a longer period of exploration, there is no message about the actual danger from a broadcasting reconnaissance team.
DE-OS 2 816 192 for a fire alarm system which interrupts the detector voltage at least once for an adjustable time after the first alarm signal and alarm signals which are immediately present when the detector operating voltage is switched on again displays as a fault and forwards alarm signals that arrive with a certain delay as real alarms.
the fire alarm control panel described here is therefore designed not to pass on a permanent response to a detector as a result of a defect as an alarm, and only secondarily to suppress false alarms as a result of brief edge effects, with signals from all detectors, in particular those with and without a time-delayed response, being the same are processed.
the object of the invention is to eliminate the mentioned disadvantages of the prior art, and in particular the method and the establishment of the type mentioned above to further develop that the security of the alarm signaling is improved, false or false alarms being largely avoided.
Another object of the invention is to design the alarm signaling method in such a way that when the system is manned by control personnel, human error is eliminated as far as possible.
this object is achieved in a method for alarm signaling of the type defined at the outset in that the signal center resets the detector a second time if it responds a second time with the shorter duration before the test time has expired and in that case an alarm signal is triggered, if the detector responds a third time after a delay time that is shorter than the difference between the two test times before the test time has elapsed and that the signaling center returns to the initial state if there is no response of the detector before the test period with longer duration has elapsed.
FIG. 1 of a device for alarm signaling designed as a fire alarm system several alarm or fire detectors D are connected to a signal center S with a common line system L.
the fire detectors can be of the same type, e.g. ionization fire detectors or optical smoke detectors, or detectors that react to other fire phenomena.
the fire detectors are expediently equipped with a self-holding circuit so that the fire detectors respond when a threshold value is exceeded, e.g. the smoke concentration, remain in the alarmed state until a possible reset.
a threshold value e.g. the smoke concentration
fire detectors of different types e.g. Detectors with different response delays are connected to the signal center at the same time, since their different properties are taken into account by the special design of the signal center, so that a special adaptation is unnecessary.
a practical exemplary embodiment of a device with commercially available ionization fire detectors as alarm detectors compared to known evaluation methods with reset and response repetition and two-stage classification (YES / NO) achieve a surprising reduction in the frequency of false alarms in practical operation, up to a factor of 5.
the device according to the invention adjusts itself automatically to the response properties of the connected fire detectors, so that no adaptation measures are necessary.
Figure 3 shows a timing diagram of such a device.
a first response (l.AL) of a fire detector the corresponding detector group is reset and the time A t until the next response (2.AL) is determined. If this time ⁇ t is greater than a certain limit time t ', the second response (2.AL) is assessed as a new event and the entire cycle is started again.
a control time V 1 which can be, for example, 2 minutes, and an exploration time V 2 of, for example, 10 minutes are started at the second response.
the control time V 1 can be interrupted by an acknowledgment signal Q, which signals the attention of the control personnel, and the exploration time V 2 can be interrupted by a reset signal E or a manual alarm signal triggered by a sent out exploration force. If these manual interruptions fail to occur, the detector group is automatically reset again at a time A t before the control time V 1 or the exploration time V 2 has expired and the test times t 1 and t 2 begin at these times t and t oo to run. In the event of a repeated, ie the third response within the test time t 2 , an alarm signal AS is then triggered immediately, t 1 can be set to 0.
