Definitions

  • the invention relates to a fire extinguishing system for gaseous extinguishing agents with a fire alarm control panel which, in the event of a fire alarm, first triggers an alarm in the extinguishing area and, after a subsequent delay, the flooding of the extinguishing area with the extinguishing agent.
  • the gaseous extinguishing agents used in such fire extinguishing systems are usually dangerous for people in the extinguishing area to be flooded.
  • CO2 carbon dioxide
  • Another commonly used extinguishing agent namely halon (bromotrifluoromethane), irritates the respiratory organs from a certain concentration.
  • halon bromotrifluoromethane
  • the delay time between the triggering of the alarm and the start of the flooding is generally measured to be approximately 20-30 seconds.
  • the invention has for its object the security for compliance with a delay time between triggering the alarm and flooding the extinguishing in the area and give priority to the activation of horns as alarms.
  • the parallel control of two delay elements operating differently and the combination of their output signals by means of an AND link ensures, first of all, with great operational reliability that the delay time is observed, since it is extremely unlikely that both delay elements will be ineffective due to any error, i. H. switch through without delay.
  • the derivation of the activation of the pneumatic horns from the trigger for the pneumatic delay element ensures that, if there is such a trigger at all, it will immediately get to the horns, i. H. only when the horns are activated will the pneumatic delay element be activated.
  • trigger signal is taken from a compressed gas container, the output of which is released by a main solenoid valve controlled by the control center, from which the compressed gas is fed via a signal range distributor via individual feed lines to the relevant one Horn as well as to the extinguishing area valve in question, the pneumatic delay element being connected to all feed lines via a check valve.
  • the main solenoid valve is connected to the series connection of valves which are controlled by the electrical delay element and the pneumatic delay element, and the series connection acts on an extinguishing agent valve, which the extinguishing agent applies to the relevant extinguishing area valve feeds.
  • extinguishing agent valves are opened by solenoid valves individually controlled by the control center by means of the compressed gas supplied via the main solenoid valve, the outputs of the extinguishing agent valves being combined to form a collecting tube from which the individual extinguishing area valves are fed.
  • the fire extinguishing system shown in the figure is controlled by the fire alarm center Z, which is activated via the alarm lines 1, 2 or 3 by corresponding fire alarms, not shown here.
  • the fire alarm control panel Z is a known circuit arrangement, the internal function of which is not important in this context.
  • the main solenoid valve 5 is connected to the control center Z, which is activated in the event of a fire alarm signaled via the signal lines 1, 2 or 3 and, through the opening caused thereby, supplies a compressed gas contained in the compressed gas container 6 to the lines 7 and 8.
  • the pressure gas on line 7 arrives at the Signal area distributor 9, which here contains the three solenoid valves 10, 11 and 12, which are individually controlled from the central station Z via the area control lines 13, 14 and 15.
  • the central area Z selects the corresponding area control line 13, 14 or 15 and activates the associated solenoid valve 10, 11 or 12. Pressurized gas then reaches one of the alarm lines 16, 17 and 18, to which the pneumatic horns 19, 20 and 21 are connected. If a fire alarm is signaled, one of the horns 19, 20 and 21 is activated in this way.
  • the horns 19, 20 and 21 are each locally assigned to an extinguishing area.
  • the extinguishing nozzles 22, 23 and 24 are also individually installed locally, to which the gaseous extinguishing agent is supplied individually in the manner explained below.
  • the extinguishing area valves (pneumatic valves) 25, 26 and 27 are arranged upstream of the extinguishing nozzles 22, 23 and 24, via the lines 28 , 29 and 30 get compressed gas, which is derived as a pneumatic signal from lines 16, 17 and 18.
  • Compressed gas is also discharged from the lines 16, 17 and 18, specifically to the pneumatic delay element 31. This is done by combining them with the line 32, so that in the event of pressure gas being present on one of the lines 16, 17 and 18, this too reaches the line 32 and thus the pneumatic delay element 31. So that, for example, compressed gas branched from line 16 to line 32 does not reach lines 17 and 18 via connection 33, check valves 37, 38 and 39 are placed in branches 34, 35 and 36, which, due to their valve action, only supply compressed gas Allow direction from one of lines 16, 17 and 18 to line 32. With the presence of compressed gas on the line 32, the pneumatic delay element 31 is triggered, which after a given one, if necessary adjustable delay time of about 20-30 seconds switches the associated valve 40 to pass.
  • the electrical delay element 41 is also triggered, which after the given, optionally adjustable delay time, emits an electrical signal on its output line 42, which reaches the solenoid valve 43 and switches it to passage.
  • two components connected to the output line 42 are initially disregarded, namely the AND circuit 44 and the electrical timing element 45. The meaning and function of these components will be discussed in more detail below. First of all, the explanation of the function of the fire extinguishing system shown is limited to the activation of the solenoid valve 43 after the delay time given by the delay element 41 has expired.
  • the two valves 40 and 43 are connected in series, thus forming an AND link which emits a pneumatic signal on its output line 46 when the two valves 40 and 43 open after the delay time determined by the delay elements 31 and 41 Passage are switched.
  • the delay times of the two delay elements 31 and 41 are set essentially to the same time period. Because of the existing AND linkage, the pneumatic signal does not appear on the output line 46 until the longer delay time has elapsed in the event of deviations in the two delay times.
  • extinguishing agent from the extinguishing nozzles 22, 23 and 24 is triggered by the pneumatic signal present on the output line 46, namely by means of the solenoid valves 47, 48 and 49 which, when switched on, pressurize compressed gas to the extinguishing agent valves 50, 51 and 52 .
  • the extinguishing agent valve 50, 51 and 52 sit on extinguishing agent containers 53, 54 and 55, in which pressurized extinguishing agent, for. B. CO2 is included.
  • extinguishing agent valves 50, 51 or 52 are switched on, extinguishing agent reaches the manifold 56, from which the extinguishing agent is then switched to the respective extinguishing area by means of the extinguishing area valves 25, 26 and 27 already mentioned above.
  • This deletion area was selected based on the activation of one of the range control lines 13, 14 and 15.
  • the arrangement of the solenoid valves 47, 48 and 49 and the extinguishing agent containers 53, 54 and 55 is therefore provided in order to switch on one or more extinguishing agent containers 53, 54 and 55 in an extinguishing area, depending on the extinguishing agent requirement.
  • the center Z stores for each extinguishing area how many extinguishing agent containers 53, 54 and 55 are to be switched on in each case.
  • a second group of extinguishing agent containers is controlled via a corresponding further group of solenoid valves and extinguishing agent valves, wherein the solenoid valves 47, 48 and 49 shown in the figure can be designed as double valves.
  • the AND circuit 44 has one input connected to the output 42 of the delay element 41, and its other input is connected to the stop line 57, on which the stop circuit 58 can supply a stop signal to the AND circuit 44 .
  • This stop signal consists of an interruption of a potential which is constantly supplied to the AND circuit 44 via the stop key 58, so that the AND condition for the AND circuit 44 is only fulfilled when the delay element 41 outputs a signal at its output 42 and also the potential present on the stop line 57 is not interrupted.
  • the stop button 58 is now pressed before the delay element 41 has expired, that is to say emits a signal at its output 42, the AND condition may not be met before the delay time expires, so that the solenoid valve 43 is activated is prevented. In this case, the compressed gas supplied via line 8 is not switched through, so that the extinguishing agent is not dispensed.
  • the above The described operating case is of importance if it is determined immediately after an alarm signal is given by one of the horns 19, 20 and 21 that, for. B. because of the presence of extinguishing agents in the extinguishing area must be prevented.
  • the timer 45 is in the connection between the AND circuit 44 and the solenoid valve 43 switched on. After its time interval has elapsed, this timer 45 limits the switching through of the signal which activates the solenoid valve 43, so that the delivery of extinguishing agent is stopped when the timer 45 expires. In this case, compressed gas can no longer get from line 8 to one of solenoid valves 47, 48 and 49, which means that extinguishing agent valves 50, 51 and 52 also switch off.
  • the afterflow button 59 is connected, at the push of which the timer 45 is triggered again, so that in the event of insufficient extinguishing, the supply of extinguishing agent can be triggered again, again for the time determined by the timer 45.
  • the delay element 41, the AND circuit 44 and the timing element 45 are components of the control center Z, which is indicated by the dashed outline of these components and the dashed box in the control center Z.
