  • the valve 9 is a manual valve.
  • the fire-fighting unit 1 is further equipped with a sensor 11 for detecting the opening of the valve 9.
  • the sensor 11 can be, for example, a limit switch placed on a handle of the valve 9 itself, which signals the turning of the handle and thus the opening of the valve 9.
  • the sensor 11 can also be a sensor detecting a pressure drop on the valve 9, located upstream of the valve 9 itself, in particular between the inlet connection 7 and the valve 9, or on the valve 9 itself, the pressure drop across the valve 9 signals that the valve 9 is open.

  • the use of the pressure-reducing valve 14 is not necessary for the operation of the fire-fighting unit 1.
  • the function of the pressure-reducing valve 14 is to ensure the correct pressure of the extinguishing substance supplied to the distributor 15. If the extinguishing substance supplied to the inlet connection 7 is already supplied at an appropriate pressure required for the proper operation of the distributor 15, the pressure-reducing valve 14 need not be used.
  • the electrovalves 16 may be arranged in several configurations as desired. For example, all the electrovalves 16 can form a single group and are all connected to a single pipe 17 which is in turn connected to the pressure-reducing valve 14. In the embodiment shown in the figures, the electrovalves 16 are divided into two groups, each group connected to a separate pipe 17, and these pipes 17 are then connected by means of a tee 18 to the pressure-reducing valve 14.

  • One of the inputs 22 of the controller 6 is electrically connected to the sensor 11 for detecting the opening of the valve 9.
  • External sensors 23 for fire detection are connected to the other inputs 22.

  • the sensors 23 may be, for example, smoke and/or heat detectors as well as thermal imaging cameras.
  • the controller 6 comprises outputs for control signals (for reasons of clarity of the figures, these outputs are not marked on the figures).

  • These sockets can, like the sensors 23 and the spraying devices 25, be associated with specific areas of the protected space. If a fire is detected by a given sensor 23, not only will the associated spraying device 25 be activated, but the controller 6 will also send an appropriate control signal to the contactors to cut off power supply to the associated sockets, thus minimizing the risk of short circuits.
  • a power supply equipment for charging the batteries may in turn be electrically connected to the inputs 22 of the controller 6 and send leakage current data to the controller 6.
  • the controller 6 may be configured such that in the event of a sudden increase in leakage current it controls, by means of its outputs, the elements that control the supply of charging voltage or current (e.g., contactors) to the batteries to cut off power supply to the sockets and hence the batteries, minimizing the risk of fire.
  • the fire-fighting unit 1 may also be supplied without the housing 2, for installation in housings already made at the site or even in rooms and/or spaces specifically designed for installing the fire-fighting unit 1 without a housing.

  • the controller 6 may be adapted to operate any number of the sensors 23, the electrovalves 12, 16 or the valves 9. For example, the controller 6 may be adapted to operate 4 sensors 23 and 4 electrovalves 16. Alternatively, the controller 6 may be adapted to operate 5-24 sensors 23 and 5-24 electrovalves 16.
  • an existing protection system in a building still comprises a plurality of the sensors 23, but is at the same time equipped with a control unit which collects signals from the sensors 23 and then generates one signal describing the status of all sensors 23, the controller 6 of the fire-fighting unit 1 can be easily configured to read such a signal and open the respective electrovalve(s) 16.
  • a control unit is connected to only one input 22 of the controller 6, and the controller 6 itself can receive fire data for the entire building only by means of this one input 22.
  • the controller 6 includes the inputs 22 for input data, which inputs 22 comprise, but are not limited to, one input 22 to be connected to the sensor 11 for detecting the opening of the valve 9 and at least one input 22 for receiving fire data.
  • the inputs 22 may also include, but not necessarily, inputs 22 for receiving leakage current data from power supply devices for charging electric vehicle batteries.
  • the outputs for control signals of the controller 6 may include, but are not limited to, outputs for controlling the electrovalves 12, 16 as well as outputs for controlling elements that control the supply of charging voltage or current to electric vehicle batteries.
  • the operation of the fire-fighting unit 1 is as follows.
  • the fire-fighting unit 1 is installed in a fire protection system comprising the sensors 23 for fire detection, the spraying devices 25 and the extinguishing substance supply and/or the pumping unit.
  • the inputs 22 of the controller 6 are electrically connected to the sensors 23 for detecting a fire in a given room or a building, or one input 22 of the controller 6 is electrically connected to the control unit collecting signals from all sensors 23 and generating one signal describing the status of all sensors 23.
  • Each sensor 23 is responsible for a separate section of a protected room/area.
  • the outputs of the controller 6 are electrically connected to the electrovalves 16 of the distributor 15 and to the electrovalve 12. The outputs of the controller 6 control the operation of the electrovalves 12, 16.
  • the electrovalves 16 are additionally flow-connected to the spraying devices 25 by means of pipes, hoses, couplings, tees etc.
  • Each spraying device 25 (and hence each electrovalve 16) is associated with a given sensor 23 and serves to extinguish a fire in the zone covered by that sensor 23.
  • the sensor 11 for detecting the opening of the valve 9 is also connected to one input 22 of the controller 6.
  • the input connection 7 of the fire-fighting unit 1 is connected to the extinguishing substance supply or the pumping unit.
  • the valve 9, the electrovalve 12 and the electrovalves 16 are closed. If a fire is detected in a certain zone of a room, the associated sensor 23 or the control unit collecting signals from the sensors 23 sends a fire signal to the controller 6. Upon receiving this signal, the controller 6 opens the electrovalve 12 so that water or other extinguishing substance can flow into the distributor 15. Simultaneously, the controller 6 opens the corresponding electrovalve 16 flow-connected to the spraying device 25 which is associated with the sensor 23 that has detected the fire. As a result, this starts the extinguishing action with this spraying device 25 and spraying the extinguishing substance in the area where the fire is present. Obviously, in the event of detecting a fire by several sensors 23, several corresponding electrovalves 16 leading to the corresponding spraying devices 25 are opened.
  • valve 9 Opening of the valve 9 causes the sensor 11 to send a signal to the controller 6, indicating that the valve 9 is open. Upon receiving this signal, the controller 6 closes all electrovalves 12, 16 so that the whole extinguishing substance supplied to the input connection 7 can now be directed only to the hydrant 5 to enable an effective extinguishing action.
  • the use of the electrovalve 12 is not necessary.
  • the electrovalve 12 is essential from the anti-freeze point of view of the entire fire protection system. If a section of the fire-fighting unit 1 containing the distributor 15 is not heated, the use of the electrovalve 12 means that before the detection of a fire there is no extinguishing substance in this distributor 15, so there is no risk of it being frozen. Moreover, the use of the electrovalve 12 facilitates maintenance work by being able to cut off the distributor 15 from the supply of the extinguishing substance.
  • a fire protection system equipped with the fire-fighting unit 1 when the need arises and a given sensor 23 covers a large area or an area of particular interest, more than one spraying device 25, and hence more than one electrovalve 16, may be associated with a given sensor 23.
  • the controller 6 is configured such that upon receiving a fire signal from such sensor 23, it sends an opening signal to several electrovalves 16, which in turn causes the extinguishing substance to be sprayed from several spraying devices 25 associated with a given sensor 23.
