Definitions

  • the present invention relates to an alarm valve station for a fire alarm system, with an alarm valve, in particular a wet alarm valve, with an extinguishing fluid inlet and an extinguishing fluid outlet, the alarm valve being set up to selectively enable or block the extinguishing fluid flow between the extinguishing fluid inlet and the extinguishing fluid outlet, a pressure sensor which is fluid-conducting is connected to the alarm valve and is set up to detect a change in pressure and convert it into an electrical alarm signal, and an alarm delay device for delaying the alarm signal.
  • the invention further relates to a fire alarm system with such an alarm valve station and a fire extinguishing system.
  • the extinguishing fluid inlet of the alarm valve of such alarm valve stations is usually fluidly connected to an extinguishing fluid supply.
  • the extinguishing fluid outlet of the alarm valve of such alarm valve stations is usually fluidly connected to a sprinkler arrangement. Triggering one or more of the connected sprinklers creates a flow of extinguishing fluid that can be (passively) released by the alarm valve and thus also detected, provided that the alarm valve, which is preferred, has one or more sensors for status detection, for example of the closed state of the valve (see for example JP H08 117357 A ), the pressure in the alarm channel (valve), etc.
  • the use of hydraulic delay tanks has some disadvantages.
  • the delay time is determined by the tank size and the pressure conditions in the water supply and cannot be changed easily without changing the delay tank.
  • the delay container is a safety-relevant hydraulic component and, as a result, involves high production and maintenance costs.
  • a hydraulic delay tank takes up a large amount of space Alarm valve station, which limits the applicability especially in confined spaces.
  • hydraulic delay tanks require such an arrangement of the lines connected to them that the extinguishing fluid automatically flows out of the delay tank, the pressure sensor and the alarm line after actuation, which limits the design options for implementation.
  • the object on which the invention is based is achieved by an alarm valve station of the type mentioned at the outset, the alarm delay device being designed as an electrical alarm delay direction and being connected to the pressure sensor in a signal-conducting manner.
  • the invention makes use of the knowledge that instead of a hydraulic alarm delay using an upstream delay container, the alarm delay can be achieved by an electrical alarm delay device which is connected downstream of the pressure sensor.
  • the electrical delay device uses the conversion of the detected pressure fluctuation into the electrical alarm signal, which is carried out by the pressure sensor.
  • An electrical delay device can be used universally, since its properties, such as in particular the delay time, do not depend on the structural design of the alarm delay device, as would be the case with a hydraulic delay tank.
  • An alarm valve station with an electrical alarm delay device also requires less production and maintenance.
  • the alarm valve of the alarm valve station preferably has a closing body, which can be moved passively back and forth between a blocking position and a release position.
  • the extinguishing fluid inlet of the alarm valve is preferably set up to be connected in a fluid-conducting manner to an extinguishing fluid supply.
  • the extinguishing fluid outlet of the alarm valve is preferably set up to to be fluidly connected to a sprinkler arrangement.
  • the closing body When the closing body is in the release position, the extinguishing fluid flow between the extinguishing fluid inlet and the extinguishing fluid outlet of the alarm valve is released.
  • the closing body In the case of wet alarm valves according to the invention, the closing body is opened passively when the pressure on the fluid inlet chamber side is higher than the pressure on the fluid outlet chamber side.
  • the alarm delay device is set up to delay the forwarding of a received electrical alarm signal by a delay period.
  • the forwarding of a received electrical alarm signal is preferably delayed by the electrical alarm signal being held back for the delay period.
  • the forwarding of the electrical alarm signal is delayed by rejecting the received primary electrical alarm signal and, after the delay period has elapsed, generating a new secondary electrical alarm signal.
  • the delay period is preferably adjustable. Because the delay period is adjustable, the alarm valve station can be adapted to the fire alarm system or the fire extinguishing system in which the alarm valve station is used.
  • the alarm valve station according to the invention is further advantageously developed in that the alarm delay device has an adjusting means which can be actuated to set the delay period.
  • the setting means is preferably designed to be operated manually. In this way e.g. Service or maintenance staff manually set the delay time of the alarm delay device on site at the alarm valve station.
  • the setting means is designed to be actuated by setting signals.
  • the setting means has one or more analog or digital switches.
  • the setting means preferably comprises one or more toggle switches, one or more rotary switches and / or one or more push buttons.
  • the setting means preferably comprises a rotary controller, a potentiometer and / or a jumper.
  • the alarm delay device has a communication module which is designed to receive and / or send data.
  • the communication module is preferably connected to the setting means in a signal-conducting manner.
  • the communication module is preferably designed to receive setting parameters, such as the delay period.

Using the communication interface (s), data can be exchanged simultaneously with several devices.
  • the alarm valve station according to the invention is further advantageously developed in that the communication module has a transmitter unit and a receiver unit and is preferably set up to exchange data bidirectionally with a remote control device.
  • the data exchange is preferably wireless. Alternatively or additionally, the data exchange is wired.
  • the alarm delay device is set up to permanently prevent the forwarding of the received electrical alarm signal and / or to reject a received electrical alarm signal.
  • the permanent prevention of the transmission of a received electrical alarm signal will also be understood in the sense of the invention as an infinite delay in the transmission of the alarm signal.
  • the operating mode of permanently preventing the transmission of a received electrical alarm signal and / or rejecting a received electrical alarm signal is used in particular when commissioning or maintaining an alarm valve station. This can ensure that at Commissioning or maintenance of the alarm valve station does not inadvertently forward an alarm signal.
  • the alarm delay device is set up to cancel an ongoing delay in the forwarding of an electrical alarm signal before the delay period has expired.
  • the alarm delay device is preferably set up to cancel an already running delay process before the end of the delay period.

  • the setting means and / or the communication module is or are combined in a control device of the alarm delay device.
  • the pressure sensor and the alarm delay device are formed separately from one another and are preferably connected to one another in a signal-conducting manner.
  • the pressure sensor and the alarm delay device are each preferably independent and structurally separate components. Since the pressure sensor and the alarm delay device can be replaced independently of one another in the event of a defect, the maintenance outlay (and thus the costs incurred) in the event of a malfunction of the pressure sensor or the alarm delay device is considerably reduced.
  • the pressure sensor and the alarm delay device are designed as a structural unit.
  • the term pressure sensor is understood as a generic term, which also includes pressure switches, for example.
  • the construction and commissioning of the alarm valve station is considerably simplified due to the smaller number of components.
  • the risk of a malfunction is reduced, since potential sources of error in the installation of the pressure sensor and the alarm delay device are avoided by designing the pressure sensor and the alarm delay device as a structural unit.
  • a further preferred embodiment of the alarm valve station according to the invention has an alarm line which is fluidly connected to the alarm valve, the pressure sensor and an emptying device, the emptying device being set up to automatically empty the alarm line and any components connected to it when the alarm valve is in Locked position.
  • the alarm line is preferably designed as an internal alarm channel and / or as an external power.
  • the remote control device is preferably designed as a stationary or portable computer or mobile radio device.
  • the remote control device preferably has a human-machine interface, such as a display, in particular a touchscreen, and / or one or more push buttons or buttons.
