Definitions
- the invention relates to a modular multi-sensor fire detector, as well as a fire alarm system with selbigem.
- Fire detectors and spark detectors are used in a well-known manner to monitor objects, such as machinery, manufacturing processes, gas turbines, warehouses and the like on the emergence of fire hazards out. This is done by using sensors to detect hazard characteristics, so-called fire or spark characteristics.
- Fire detection systems are known from the prior art, in which one or more fire detectors are installed in a room or in an area to be monitored. If the sensors installed in the fire detectors detect the respective fire characteristic, they send an alarm signal to an alarm signal receiving device.
- a gas alarm panel for example, a radio control panel, a fire alarm panel and / or extinguishing control center, a control center for controlling non-extinguishing functions (such as parking facilities, for operating shut-off devices for material or energy flows, for opening and closing Materialaustragsklappen) and the like ,
- a fire detector is understood to mean a detector for detecting fire and / or hazard parameters and spark detection, in particular electromagnetic radiation as fire parameters and / or danger parameters Radiation, aerosols (especially smoke aerosols), temperatures, gas concentrations, gas compositions and / or changes in concentration of certain gaseous components of fire gases, thermal decomposition products, toxic or combustible gases are understood.
- the document DE 10 2006 055 617 A1 relates to the fire protection of technical installations and plant buildings, in particular a fire alarm system.
- the fire alarm system includes a fire alarm panel coupled to various sensors for detecting environmental conditions.
- Sensors are to be detected in a danger zone around hazards and their sizes.
- the sensors are fire detectors, for example.
- Fire control panel is not located in or near the danger area, but is placed in another location, for example in another room.
- the document DE 198 45 553 C2 relates to a fire detector with a sensor system, which is formed from various sensors and with a control and evaluation.
- the fire detector transmits an evaluated fire alarm signal to a fire alarm control panel via a bus interface.
- the document EP 1 052 607 A1 discloses a method and a device for the parameterization of a security system.
- the security system comprises a control center, from which several danger detectors, such as fire or Intusion detectors, are connected via a detector bus.
- the parameterization of the control panel via a connected via a communication connection to the interface of the control panel PC.
- US 2013/0315605 A1 relates to a security system, such as a fire alarm system within a building.
- the system has a plurality of detectors which are connected to one another or coupled to one another via a network.
- Each of the fire alarm sensors is registered in the fire alarm system and registered accordingly. If a sensor is replaced, is the newly installed sensor is reconfigured in the system so that it can at least be localized in the fire alarm system.
- multi-sensor fire detectors are known in which a plurality of sensors are permanently installed in a housing together with an evaluation unit.
- an evaluation unit for example.
- One of the sensors the whole detector must be replaced, and for this period no monitoring can take place.
- the range of application of such detectors is also very limited.
- evaluation electronics are installed in addition to the pure sensors in a fire detector according to the state of the art. Since fire alarms must be installed in or at least very close to the danger area in order to reliably detect hazards, the fire detectors must meet high safety requirements and environmental requirements, for example with regard to their suitability for use in potentially explosive atmospheres (resistance to ignition), their resistance to high levels of fire safety Temperatures, electromagnetic radiation, or tightness against fluid entry (gaseous or liquid). Depending on the working environment, the fire detectors must also be dust-proof.
- the invention was based on the object of specifying a fire detector which as far as possible overcomes the disadvantages found in the prior art.
- the invention was based on the object of specifying a fire detector, which offers at low system costs undiminished high protection of the sensors from environmental influences in the danger areas.
- the invention was in particular the object of specifying a fire detector installed in fire alarm systems with little effort and especially retrofitted, maintained and can be rededicated for the detection of other hazard characteristics.
- the invention was in particular the object of proposing a fire detector that is flexible to handle in terms of its installation, and in particular in particularly cramped conditions, such as in the object protection of machine tools, can be installed.
- the invention solves the underlying task by proposing a modular multi-sensor fire detector according to claim 1.
- the modular multi-sensor fire detector has an evaluation unit and a plurality of sensor heads, which are arranged spatially spaced from the evaluation unit, and which are connected signal-conducting with the evaluation unit, wherein the evaluation unit is signal conductively connected to a spatially spaced alarm signal receiving device, so that the evaluation unit, the sensor heads and the alarm signal receiving means are not integrated in a common or in a plurality of housings mounted together.
- the invention accordingly makes use of the knowledge that the protection of the sensor head, which is arranged directly in the danger zone, is given a higher priority than the protection of the evaluation unit, which does not necessarily have to be arranged in the danger zone.
- the sensor heads according to the invention are spatially separated from the evaluation unit following this approach. This has several advantages: On the one hand, the sensor heads, due to their separation from the evaluation unit, allow a much more compact design than the prior art and can be installed in locations where conventional detectors can not be used.
- the evaluation unit which is spatially separated from both the sensor head and the alarm signal receiving device, converts the detector architecture into a three-stage system in which the sensor head represents the first stage, the evaluation unit the second stage, and the alarm signal receiving device the third stage of a fire alarm system.
- locally deposited is meant that the so-called elements structurally separated from each other, in particular not integrated in a common or multiple housings mounted together, and are spatially spaced from each other.
- the evaluation unit, the sensor heads and the alarm signal receiving device are not integrated in a common or in several housings mounted together.
- the evaluation unit is set up to be optionally signal-connected to a plurality of sensor heads of different or the same type. This significantly increases the flexibility of the fire detector according to the invention to the effect that always the same evaluation unit can be used in conjunction with a locally required combination of sensor heads.
- the evaluation unit is preferably set up to send an alarm signal adapted to the communication with the alarm signal receiving device, irrespective of the sensor head compatible with it. This significantly reduces the cost of the device and programming on the part of the alarm signal receiving device. Regardless of which sensors are used, the alarm signal receiving device is always sent the appropriate signal in the presence of a hazard. In this way, the evaluation unit takes over the evaluation of the alarm signals transmitted by the sensor heads as an upstream signal processing or interpretation unit. The technical effect of such "distributed intelligence" leads to a reduction in response times, since the alarm signal receiving unit is relieved by the upstream, decentralized evaluation.
- the invention is further developed in that the evaluation unit has a plurality of first interfaces for signal-conducting connection of the evaluation unit with the sensor heads, and at least one second interface for the signal-conducting connection Evaluation unit with the alarm signal receiving device.

- the detection and storage of the temperatures at the sensor head offers the possibility to create a temperature history, which documents when the sensor head was exposed to which temperatures.

- a protective cap 203 which is attached to the housing 201 on the side of the first interfaces 219, is shown in FIGS. 2a-c.
- the protective cap 203 protects against unintentional release of the data lines from the first interfaces 219 and protects the connection against external force (such as shocks, shocks).
- the protective cap 203 is secured captively to the housing 201 by means of fastening means 205, for example screw connections.
- a third interface 222 is indicated in addition to the second interface 208.
- the third interface 222 is set up to communicate preferably bidirectionally signal-conducting with a configuration device such as, for example, a portable computer, tablet, service device or mobile telephone.
- the fire alarm system 400 further comprises the alarm signal receiving device 301, which preferably according to the above described preferred embodiments is formed.
- the evaluation unit 200 is locally spaced from the alarm signal receiving device 301, which is formed in this embodiment as a fire alarm and / or extinguishing control center.
- the configuration of the evaluation unit 200 preferably takes place via one or more hardware switching elements 242, for example DIP switches, and / or via the third interface 222.
- the third interface 222 preferably receives from one Configuration device 221, such as a portable computer, tablet, service device or mobile phone, a plurality or all of the following: configuration parameters K, firmware F, configuration data D, control commands B.
- the received elements are from an electronic module 212, comprising a computer unit 206, for example in Form of a microcontroller, processed and / or forwarded by means of the first interfaces 219 to the sensor heads 100.
- firmware data F configuration data D
- control commands B for actuating the sensor heads 100, for example for self-testing or self-calibration measures.
- the elements K, F, D, and B could alternatively also be recorded by means of the third interface 222, and / or by the alarm signal receiving device 301 and via the second interface 208, provided that the respective interfaces for bidirectional data transmission are set up.
- the evaluation unit 200 is set up by means of the electronic module 212 and the computer unit 206 to store the received configuration parameters K in a memory 215 and to configure the first interfaces 219 on the basis of the configuration parameters K.
- the first interfaces 219 are configured, at least, such that the evaluation unit 300 allocates, for each of the first interfaces 219, whether a sensor head 100 is to be connected to the interface for operation, and preferably of what type the sensor head 100 is to be connected ,
- the evaluation unit 200 is set up to generate an alarm signal S A on the basis of the configuration parameters K if danger signals S G or normalized danger signals S ou t are received by the first interfaces 219 in a predefined constellation.
- Different constellations can be, for example, the following:
- First interfaces 219 which are not to be used during operation, are preferably closed by means of a cap 220.
- one or more configuration parameters K are provided, either directly by means of the hardware switching elements 242, from the memory 215 of the evaluation unit 200 or by means of the third interface 222.
- a device mode is started at the evaluation unit 200, either via the configuration device 221 third interface 222, or via one or more separate, externally, in particular manually, controllable switching elements 216, 217, which are preferably designed as magnetically actuated reed contacts.
- the evaluation unit 200 sends a request signal S req via those first interfaces 219, which are assigned to a sensor head 100 by means of the configuration parameters K, via those first interfaces 219. Is received unless the request signal S req via the interface 104 from the sensor heads 100, the sensor heads provide 100 sensor head data 1 17 219 to the first interfaces If the signal S is not req by the sensor heads 100, an interference signal is generated.
- the evaluation unit is set up to match the sensor head data received from the sensor heads 100 with the configuration parameters K previously provided to it. Do the sensor head data 1 17 for the respective sensor head 100 at the respective first interface 219 match, i. E. if the sensor head is actually connected to the first interface 219, which has been previously assigned by means of the configuration parameter K, the evaluation unit 200 preferably generates an acknowledgment signal or information element.
- the setup mode is automatically terminated and the operating mode is entered.
- the operator is hereby notified, preferably by optical and / or acoustic indication, and the setting-up mode is also terminated, without, however, entering the operating mode.
- An interference signal is preferably generated not only when there has been no transmission of sensor head data to evaluation unit 200, but also when sensor head data 11 has been transmitted, but these do not agree with the previously provided configuration parameters K for the respective first interface 219.
- the invention provides a particularly simple way of installing a complex, modular multi-sensor fire and / or spark detector system.
- the device and interpretation of the danger signals provided by the sensor heads is preferably automatically taken over by the evaluation unit, so that the rather complex multisensor detector communicates to the outside, ie to the alarm signal receiving device 301, like a single detector. Particularly in the case of complex objects with a large number of areas to be monitored and a large number of detectors used, this ensures considerable relief on the part of the alarm signal receiving device.
- the multi-sensor fire detector according to the invention plays the strength of its compact design and distributed architecture in cramped environments.
- Interface sensor head 104 central data storage 105th
- Computer unit 206 second interface 208
- Configuration device 221 third interface 222
