EP2907115B1 - Arrangement for monitoring and earliest detection of fire for a plurality of potentially flammable or potentially explosive vessels and/or housings - Google Patents

Description

The invention relates to an arrangement for monitoring and early fire detection for several fire and / or explosion-prone vessels and / or housings, such as switch and distribution cabinets and electrical engineering devices, IT cabinets and devices, and devices of all sizes and designs of ventilation, air conditioning - and cooling technology (eg convection cooling, water cooling, radiation cooling).

In the prior art, fire detectors are used for room monitoring. A typical example of this is the solution according to DE 602 16 295 T2 by means of which the hold of an aircraft is to be monitored. For monitoring purposes, fire detectors are arranged in grated niches which are provided for the installation of these fire detectors and which are always arranged in the same place in the room for every aircraft of this type and also for every load / freight. Two smoke detectors are arranged in each of these niches, of which each of the smoke detectors of the pair of smoke detectors of each niche are each connected to one another via a separate linear CAN-BUS system.

In the prior art, smoke detectors are used as individual detectors for room monitoring, the structure of which, for example, in the DE 197 33 375 A1 is described.

The solution after DE 197 33 375 A1 describes the basic structure of such a smoke detector, which essentially consists of a "base part" and a "cover part", which are designed with a "bayonet coupling" and "connection contacts" as plug contacts.

A wide variety of detection principles and detection criteria, such as e.g. Scattered light, temperature change or particle size, type of aerosol etc., used with the most diverse signal processing algorithms for smoke and temperature and or CO detection in the designs of smoke or multi-criteria detectors.

In these designs, lasers, UV and IR diodes are used in conjunction with a variety of evaluation algorithms.

Such individual detectors are for example in the EP 0338218 A1 and the US 8,154,415 B2 described in different designs. The Indian EP 1630758 A2 The multi-criteria smoke detector described above, a scattered light smoke detector is characterized by a high level of false alarm security and a short response time.

These detectors are used on the one hand as built-in devices for fixed installation at fixed points (e.g. front installation) or only for certain housings (e.g. PC). In this design, these detectors are then regularly separated, i.e. Standalone, operated.

So in the DE 41 34 400 C1 For example, a solution has been previously described which uses the chimney effect that warm air creates in the slim, tallest possible vessel ("chimney") for the installation of the detector. The warm (specifically lighter) air rises, while colder air is drawn in below due to negative pressure.

This chimney effect is reinforced by the fact that a chimney made of sheet metal is placed on the vessel to be monitored, in which the individually operated detector is then arranged.

In addition to the use of the detectors in standalone operation, the prior art also specifies monitoring principles for monitoring several buildings or devices, with special arrangements of individual detectors, in which these aforementioned individual detectors are used and coupled to one another.

So already describes the DE 615516 C an arrangement known as an MMS system of an electrical fire alarm system with alarm points which, for reasons of line economy, are connected to a control center by a common ring or loop line.

This solution is equipped with a mechanical pulse generator (cam wheel). The ring-shaped arrangement of subscribers, which is referred to as ring bus in electronics today, is also found in the DE 297 18 099 U1 for controlling fire protection and smoke extraction dampers in smoke and heat exhaust ventilation systems. This in the DE 297 18 099 U1 In the event of a short circuit, however, the system described is not able to selectively activate an individual bus subscriber; rather, this can only be done for one of the ring elements then remaining, which inevitably leads to the failure of the ring segment concerned.

This remaining residual risk is unacceptable in sophisticated security technology, where the lowest possible part of a ring must always be switched off.

Another solution based on a BUS system is in the EP 01 413 997 A2 previously described. The main element in this solution is a combination module mounted on a top-hat rail.

This essentially consists of the smoke detector, which is firmly connected to the housing, a power supply unit and the evaluation unit. However, due to the fixed type of fastening (top hat rail), these can only be used with considerable restrictions at the place where the fire originates. This essentially limits their applicability to large, convection-ventilated control cabinets, which have relatively low requirements regarding false alarm security.

Furthermore, this solution has the disadvantage, among other things, that in addition to the sensor, a power supply unit and an evaluation unit (in a housing) must always be installed on-site, which not only results in a high space requirement, but also a higher cost, energy losses, or a high cost decentralized battery monitoring and care results.

This system is also based on the use of open, linear buses with the resulting extensive, "tree-like branching" of the systems.

Resource limits for ports and local power supply can result in high costs even when the systems are being built. This becomes even more obvious when it comes to service, since each structure is unique and changes and extensions (in practice) are often not documented, which reduces security and makes service more expensive.

Short-circuiting or interruption of a "branch" also lead to partial or total failure of the system, as well as a non-existent or insufficiently maintained (because decentralized) emergency power supply.

A sensible applicability of the in the EP 1 413 997 A2 The solution disclosed therefore essentially limits its area of use to vessels in the area of the power supply systems.

With a broader application, where universal applicability in vessels (almost) of all sizes, ventilation conditions, extreme false alarm security and maximum availability is important, this system quickly reaches its limits and is then no longer effective for cost reasons.

Even the solution after WO 2010/083839 A1 can be classified in the category BUS systems in the broader sense.

Yet another solution is in the US2004 / 0056765 shown, which is based on the use of a CAN bus.

This is an early fire detection system with front installation, in which smoke / temperature detectors are used in such a way that a fire criterion can trigger an alarm.

However, the inevitable necessity of the arrangement in the front part of a vessel / housing has mandatory use restrictions, i.e. it cannot be used for very small vessels or inaccessible / invisible vessels or vertically ventilated vessels.

In other cases, the usage restrictions also have technological reasons (e.g. glass door, space problems, etc.) or the arrangement is outside the air flow to be monitored, so that this solution can only be used for control cabinets / boxes.

The emergency power supply used in this solution by means of decentralized backup batteries in the cabinet installation modules also have the same problems as in connection with the solution according to the EP 1 413 997 A2 described (high maintenance costs, lack of monitoring, increasing uncertainty about the available battery capacity after a long period of operation, etc.).

In addition to visual / acoustic messages, the system also enables switching operations (e.g. switching on the extinguishing system / s), but this property appears very risky, for example, in IP cabinets, since the damage caused by a false alarm can be very high.

In this solution too, auxiliary devices such as power supply, evaluation unit, local signaling, etc. are accommodated in a housing in addition to the sensor (s). This in turn results in a large, larger installation volume and high energy consumption.

When using decentralized emergency power batteries, their maintenance is problematic and requires additional costs.

In addition to the use of a wide variety of detectors in standalone operation or in BUS systems, a further monitoring principle, the smoke aspiration principle (monitoring of air sucked in via pipes for fire indicators, RAS) is prescribed in the prior art.

This smoke aspiration principle has the monitoring and early fire detection for fire and / or explosion-prone vessels and / or housings, such as control and distribution cabinets and electrical engineering devices, IT cabinets and IT devices, as well as devices of all sizes and designs of ventilation, air conditioning - and cooling technology (eg convection cooling, water cooling, radiation cooling) is currently the most widespread.

It is typical for vessel monitoring that primarily the vessels (e.g. switchgear and control cabinets) are monitored which contain a fire load and / or one or more ignition sources (e.g. electrical components) and which can to a large extent be potential triggers for fires , or which, due to their importance (availability), must be protected against fire or failure damage.

Compared to room monitoring, the earliest fire detection in the vessels, ie vessel monitoring, has a number of advantages. For example, the heating of individual components is already recognized without damaging the others, the endangered object is still in operation and there has been no fire, shutdown, extinguishing or personal injury. Such a "self-priming fire alarm device", which works for monitoring and early detection of fire and / or explosion-prone vessels and / or housings and operates according to the smoke aspiration principle, is described, for example, in US Pat EP 1 389 331 B1 previously described. Although this solution is intended to improve sensitivity, false alarm security and detection speed, this solution also has the basic disadvantages of smoke aspiration systems (RAS).

On the one hand, smoke aspiration systems, regardless of their design and sensor technology, are relatively expensive because they each require a complex infrastructure for one or two highly sensitive smoke detectors (fan and filter unit, their own power and emergency power supply, their own control and function monitoring, monitoring of the sensitive pneumatic smoke aspiration system, system control , Forwarding, calculated and calibrated raw system etc.) is required, whereby the suction of the air to be detected is also carried out via a pipe system with moving (wear) parts, fan module (s), complex energy, control and monitoring devices, filter units and only indirectly with the smoke suction systems ( RAS) pipe system to be checked. On the other hand, the smoke suction pipes generally have smoke suction openings that are precisely calculated in terms of distance and size, via which individual vessels or monitoring zones in the vessels are then to be detected. Since the openings are passive, malfunctions (eg closure by dust, objects, insects, etc.) can only be detected indirectly via air pressure evaluations. This in turn is complex and not always reliable due to other disturbances (fluctuations in air pressure). In addition, they have to be re-measured during commissioning and after each change.

Another disadvantage of the RAS is that if smoke particles are sucked in in the area of a suction opening, these are usually diluted by the uncontaminated air of the unaffected suction openings, in relation to the number of holes.

In the case of 5 objects to be monitored via 5 suction openings, the aerosol concentration at the detector (regardless of the type) causing the fire is in principle only a maximum of 20% of the concentration at the source of the fire.

In practice, the conditions are often even worse and therefore require the use of several RAS detectors, especially when reliable individual detection of the source of the fire is important, e.g. in the event of deletion and shutdown. In any case (even with incorrect triggering) these lead to high costs.

A decisive system disadvantage of RAS is the inaccurate identifiability of the smoke suction hole through which the smoke particles enter.

In addition, RAS cannot be used everywhere, e.g. not in vessels with small (size), tightly sealed vessels, e.g. low-voltage or main distribution boards with a high degree of protection such as IP 65 and higher, because they do not allow air to be exchanged to the outside, or because there is usually no space in them.

Due to the system, the monitoring of several vessels with their own ventilation is problematic for all RAS, since there are differences in air pressure from vessel to vessel and these change constantly (e.g. due to equipment, vessel temperature-dependent / multi-stage fans, opening and closing, etc.).

A false alarm-proof function of a RAS is only given if the optimal values measured during installation remain stable over the long term.

In practice, this is often difficult, very complex and ultimately also cost-intensive.

In the WO 2007/051517 A1 a solution is described which has such a smoke suction principle to the content.

Essentially, this solution works according to the basic principle of RAS, but tries in particular the disadvantage of not being able to locate the smoke suction hole in question due to a complicated process (reversal of flow of the detection air after the first detection - blowing out the pipes with fresh air - renewed suction of the detection air - measuring the Runtime of the fire parameter up to the sensor - calculating the position of the smoke suction hole - issuing the alarm).

Implementation of the in the WO 2007/051517 A1 However, the above-described solution inevitably results in significantly higher manufacturing, operating and maintenance costs and increases the disadvantages of the pressure fluctuation problem described above, as a result of which changing pressure conditions lead to incorrect detections, and this can only be eliminated by costly, ongoing monitoring or readjustment.

Another very important disadvantage of this smoke aspiration principle is the very long, in many cases intolerable detection time.

In the solution after the WO 03/069571 A1 another solution based on the RAS principle is described, which has a suction line for each vessel.

Although this improves the individual detection of the source of the fire, all other disadvantages described in connection with the use of RAS also occur with this solution.

If, for example, an existing "complete system" monitored by a RAS is to be expanded or often re-equipped, the smoke aspiration systems (RAS) used in the prior art quickly reach technical as well as economic limits.

The invention is therefore based on the object of eliminating the abovementioned disadvantages of the prior art and of developing an arrangement for monitoring and early detection of fire-prone and / or explosion-prone vessels and / or housings which, at reasonable plant costs, are an alternative to those currently available in the prior art Technology, for example in the switching u. Server cabinets from data centers (e.g. at banks etc.), smoke detectors used with their, the switching u. Server cabinets can be used with the pneumatic pipelines connecting the evaluation unit, and at the same time a much more cost-effective and precise, as well as much more false alarm-proof monitoring of a much higher number of "measuring points" (e.g. server cabinets) using only one evaluation unit, with significantly reduced production -, assembly, maintenance and repair work, high flexibility and high availability, even during maintenance work, but also during the necessary expansion work of the overall system.

According to the invention, this object is achieved by an arrangement for early detection of fire for fire and / or explosion-prone vessels and / or housings according to the features of the independent device claim of the invention.

Figure 1A and Figure 2A show the structure of a, in the arrangement according to the invention for monitoring and early fire detection for fire and / or explosion-prone vessels and / or housing duo detector module 3 according to the invention in side view and top view.

The dual detector module 3 consists of a detector module housing 5, preferably made of plastic, which is composed of a lower housing part 6 and an upper housing part 7 fastened to it by means of a screw or clip connection 26, and that in the upper housing part 7 with two openings 14 for the two smoke detectors 2 ( an opening 14 for the smoke detector I 2.1 and the smoke detector II 2.2) is provided.

The screw or clip connection 26 can be implemented both as a releasable connection (e.g. by means of screws and clips) and as a non-releasable connection (e.g. gluing or riveting) (joint connection).

The smoke detectors 2 (2.1 and 2.2) are connected in a so-called two-detector dependency, i.e. An alarm is only triggered when both smoke detectors 2 report the same fire criterion (AND function). This type of circuit considerably reduces the risk of false alarms and improves the arrangement according to the invention, in particular for controlling extinguishing devices in vessels.

The openings 14 are designed so that the smoke detectors 2 (2.1 and 2.2) can be removed from the outside without removing the upper housing part 7 (the opening diameter is larger than the smoke detector diameter).

A motherboard 8 is arranged in the interior of the detector module housing 5. The upper housing part 7 protects the motherboard 8 from contact and dust. The dual detector module 3 has a ring bus input 11, a ring bus output 12 for the ring bus 18 and an external signal output 13 as signal inputs and signal outputs. These signal inputs and signal outputs are connected by means of connecting cables 31 through industrial connectors 30 arranged on the side of the detector module housing 5.

The (occasionally requiring maintenance) smoke detectors 2 can be easily removed or reinserted for maintenance purposes from the detector bases 9 with plug-twist lock, here bayonet lock, arranged in the lower housing part 6 on the motherboard 8, without having to loosen or open the upper housing part 7. This enables easy maintenance of the smoke detector 2.

The smoke detectors 2 (like also the 2.1 and 2.2) also protrude with their perforated smoke detector upper part 15 from the upper housing part 7, so that their internal sensors can be easily and quickly reached by smoke particles. The motherboard 8 fastened in the bottom of the lower housing part 6 realizes the electrical connections between the smoke detectors 2 (smoke detectors I 2.1 and smoke detectors II 2.2) and the industrial connectors 30, for the ring bus input 11, for the ring bus output 12, and for the external signal output 13 and the via conductor tracks Isolator 10 located in the detector module housing 5.

By decoupling sensors and auxiliary devices, such as local power supply, signal processing, signaling, etc., which in the central evaluation unit 19, Figure 13A and Figure 13B , are advantages such as low price per module, very good energy balance per module, low maintenance costs per module and a compact design per module. The inventive arrangement of the detector base 9 and isolator 10 of the base board 8 also enables industrial series assembly with good quality, low manufacturing price and compact design of the dual detector module 3.

The compact design of the dual detector module 3 also allows installation in small vessels or in larger vessels at any (optimal) location, which considerably expands the possible uses (variable use).

Thanks to the exclusively electrical connection (connection cable 31) of the modules, there is no need for complex, sometimes fault-prone and inflexible piping as in smoke aspiration systems (RAS).

In the event of a malfunction (interruption or short circuit) of a subscriber or of a segment in the ring bus 18 (ring bus subscriber or ring bus segment), the isolator 10 connected on the motherboard 8 realizes its disconnection or activation.

A great advantage when using a disconnector 10 in the detector modules (dual detector modules 3, dual detector modules 3e, dual detector modules 3i, single detector modules 4, single detector modules 4e, single detector modules 4i) is that only the smallest possible part of the ring bus 18 (see Figure 13A , 13B , 14 , 15 ) or the monitored objects, must be switched off in the event of a fault. On the other hand, this principle allows changes and extensions to the ring bus 18 (see Figures 13A , 13B , 14 , 15 ) during ongoing operation without the overall monitoring function being impaired during this time.

Safe electrical connections to the ring bus input 11, to the ring bus output 12 and to the external signal output 13 are implemented via the three industrial connectors 30. The industrial connectors 30 (plugs or sockets) built into the lower housing part 6 implement a fast and secure connection by plugging in the external sockets (ring bus input 11 and ring bus output 12 or external signal output 13) via plugs.

The principle of the industrial plug connector 30 also supports a quick change of location in the vessel to be monitored (for example in the case of changed use) and a quick replacement or reassembly of the detector modules (dual detector modules 3, dual detector modules 3e, dual detector modules 3i, single detector modules 4, single detector modules 4e, single detector modules 4i) .

All industrial connectors 30 have a fuse that prevents accidental loosening.

The connection cable 31, for ring bus 18 and external signal transmitter 27, Figure 7 , are relieved of strain in the respective vessel 1 in cable guides provided for this purpose and continued.

On the lower housing part 6, one or more adhesive element (s) 17 according to the invention is applied over the entire surface or partially (firmly joined).

It consists of either a magnetic adhesive film or non-detachably attached magnetic magnets (depending on the surface). This type of attachment allows quick mounting on steel surfaces, which is usually possible without any problems.

As a further option for quick attachment, a strong adhesive Velcro tape combination with both housing base 16 ( Fig. 1A , Figure 3A and Figure 5A ) and vessel 1 are firmly connected so that the module can then be easily attached in non-magnetic vessels. Combinations with double-sided adhesive tape are also planned.

All types of installation (magnetic, adhesive tape and Velcro principle) are characterized by screwless fastening including the omission of drilling and screwing.

A great advantage of this embodiment according to the invention is that a major source of danger for IT and electrical devices, namely metal chips and lost screws, is fundamentally prevented. This means that systems in operation can be safely upgraded / retrofitted. Furthermore, there is a high degree of flexibility in the arrangement of the detector modules, even when changing the installation location (e.g. when changing use).

In the event of a defect, the modules can be exchanged quickly.

Due to the high adhesive force of the detachable connections, operational loosening or shifting is excluded, so that a secure and long-term stable attachment is given according to the invention.

Another, second embodiment of the dual detector module 3 according to the invention, namely the dual detector module 3e, is shown in FIG Figure 1B in the side view and in the Figure 2B shown in top view.

In principle, it has the same functionality as the duo detector module described above according to the Figure 1A and Figure 2A .

However, for reasons of manufacturing economy and a possible smaller "medium" overall size, it consists of two similar cuboid (angular) housings 5, each consisting of lower housing part 6 and upper housing part 7, which are mounted on a common motherboard 8. The adhesive element (s) 17 is / are also attached to this motherboard 8. The motherboard 8 of the Duomedmelder module 3e (according to Figure 1B and Figure 2B ) therefore no longer has the function of the electrical connection of the two smoke detectors 2 (2.1 and 2.2), but only the constructive load-bearing function for the detector base 9 and for the adhesive element (s) 17.

The smoke detectors 2 (2.1 and 2.2) are electrically connected via wire-shaped conductor connections.

In contrast to the embodiment according to Figure 1A and Figure 2A has in the embodiment according to the Figure 1B and Figure 2B , ie in the duomed detector module 3e, each detector base 9 has its own isolator 10. This has the advantage that the rest, even if there is an open circuit and / or short circuit between the smoke detectors 2 (2.1 and 2.2), and if one of these two smoke detectors 2 fails of the ring bus 18 remains in operation.

All other components are, as in the previous embodiment in connection with the Figures 1A and 2A described with the same functionality.

Another, third embodiment of the dual detector module 3 according to the invention, namely the dual detector module 3i, is shown in FIG Figure 1C in the side view and in the Figure 2C shown in top view.

In principle, this design also has the same functionality as the dual detector module 3 as described for that Figure 1A and Figure 2A . Due to the manufacturing economy and possible, even smaller "minimized" overall size, in contrast to the dual detector module 3 according to the Figures 1A and Figure 2A , two similar cylindrical (round)

Detector module housing 5, consisting of only one lower housing part 6, mounted on a common motherboard 8.

That in this embodiment, according to Figure 1C and Figure 2C "Eliminated upper housing part 7" and the standardized lower housing part 6 lead to a smaller design with lower manufacturing costs and an improved overall economy of this dual detector module 3i compared to the aforementioned designs 3 and 3e.

Like in the Figure 2C are shown, the three industrial connectors 30, the signal input 11, the signal output 12 and the external signal output 13 are integrated directly into the two lower housing parts 6.

On the motherboard 8 of the dual detector module 3i, the adhesive element (s) 17 is / are arranged analogously to the dual detector module 3e.

The motherboard 8 of the duo detector module 3i, as in the Figures 1C and 2C shown, no longer the function of the electrical connection of the smoke detector 2 (2.1. and 2.2), but only causes a constructive, load-bearing function for the detector base 9. The electrical connection of the smoke detector 2.1 and the smoke detector 2.2 is also carried out in this solution wire-shaped conductor connections.

Analogous to that in the Figures 1B and 2 B The illustrated solution of the dual detector module 3e also has a separator 10 in the dual detector module 3i for each detector base 9.

This has the advantage that even in the event of a line interruption and / or short circuit between smoke detector 2.1 and smoke detector 2.2 or in the event of the failure of one of these two smoke detectors 2, the rest of the ring bus participants are activated and the ring bus 18 remains in operation.

All other components and arrangements of the duo detector module 3i are, as in the duo detector module 3, or in the duo detector module 3e, with the same functionality.

The representations of the Figure 3A and Figure 4A show the structure of a mono-detector module 4 according to the invention in the version of the mono-detector module 4.1 (single module) in the arrangement according to the invention for monitoring and early detection of fire for fire and / or explosion-prone vessels and / or housings in side view or top view.

The mono detector module 4.1 consists of a lower housing part 8 and an upper housing part 7 fastened to it by means of a detachable screw or clip connection 26, which is provided with an opening 14 for the smoke detector I 2.1.

The opening 14 is designed so that the smoke detector I 2.1 can be inserted from the outside without removing the upper housing part 7 (the opening diameter is larger than the smoke detector diameter).

The smoke detector I 2.1 can be easily removed or reinserted for maintenance purposes from the detector base 9 with bayonet lock, which is fastened in the lower housing part 6 on the motherboard 8, without having to undo the upper housing part 7.

The smoke detector I 2.1 with its perforated smoke detector upper part 15 protrudes above the upper housing part 7 so that its internal sensors can be easily and quickly reached by smoke particles.

The motherboard 8 fastened in the housing base 16 of the lower housing part 6 realizes the electrical connections between the smoke detectors I 2.1, the industrial connectors 30 for the ring bus input 11, and the ring bus output 13 and the isolator 10 located in the detector module housing 5 via conductor tracks.

The inventive arrangement of the detector base 9 and the isolator 10 on the motherboard 8 enables a good industrial series assembly of the entire components, a good quality, a low manufacturing price and a compact design of the mono detector module 4. It will have the same advantages as in Fig. 1A and Figure 2A , for the duo detector module 3, achieved.

The isolator 10 of the single detector module 4.1 connected on the motherboard 8 fulfills the same function as the isolator 10 used in the dual detector module 3.

For the industrial plug connector 30 as well as for the adhesive element (s) 17, the same applies analogously to this in connection with the dual detector modules 3 (see explanations for the Figures 1A and 2A ) described means-effect relationships.

The Figures 5A and 6A show the structure of the second embodiment of the single detector module 4, which is always assigned in pairs to the single detector module 4.1, a single detector module 4.2 in a side view and in a top view. Basically, the mono-detector module 4.2 has almost the same structure as the mono-detector module 4.1, but has no isolator 10, but additionally the external signal output 13. The two mono-detector modules 4.1 and 4.2 are always used in pairs.

The mono detector module 4.1 with isolator 10 is used for the integral monitoring of a vessel (see Figure 9 ) connected to the single detector module 4.2 in a two-detector function (always in pairs).

This makes it possible in certain applications (e.g. forced air cooling) not only in a representative zone (such as with duo detector modules 3 acc. Fig. 7 ) to measure, but to evaluate the entire air content of the vessel and thus to carry out an integral measurement. In critical applications, this type of installation considerably reduces the probability of false alarms.

As a distinguishing feature of the single detector module 4.2 compared to the single detector module 4.1, this single detector module 4.2 has an additional external signal output 13, for example for external signal transmitters 27 ( Fig. 7 and Fig. 9 ) that can be installed locally on the vessel to be monitored if necessary. In addition, the mono-detector module 4.2 does not have a disconnector 10, since this is contained in the mono-detector module 4.1 in its design.

According to the invention is also in the Figure 7 External signal generator 27 shown, as in connection with the in Fig. 1A and 2A components shown described, also equipped with one or more adhesive element (s) 17. This means that the external signal transmitter 27 can also be installed without screws or chips, which considerably reduces the security risk in IT environments and power supply systems.

The two mono-detector modules 4, the mono-detector module 4.1 and the mono-detector module 4.2, which are always used in pairs, provide the same function in the interconnection as the duo-detector module 3, but with the difference that an integral monitoring of vessels is possible with the principle of separately mounting the detector modules ( see the explanations in connection with Fig. 9 ).

A second embodiment of the mono detector module 4.1 according to the invention (with 2 industrial connectors 39), in a "medium" size, namely the mono detector module 4.1e is shown in FIG Figure 3B in the side view and in the

Figure 4B shown in top view.

The Monomedmeldermodul 4.1e has the same functionality as that in the Figures 3A and 4A Mono detector module 4.1 shown, but has a somewhat smaller, so-called "medium" overall size in its dimensions.

For reasons of manufacturing economy, but also to increase the reliability, in this embodiment, in contrast to that in the Figure 3A and Figure 4A Embodiment shown, the disconnector 10 relocated in the detector base 9.

In this embodiment, the detector base 9 is mounted directly on the housing base 16 by means of a screw and / or clip connection 26.

The motherboard 8 no longer has the function of the electrical connection between the smoke detector 2.1 and the isolator 10 in the monomed detector module 4.1e, but only the constructive function of the fastening.

Therefore, only the detector base 9 and the adhesive element (s) 17 are attached "on top" of the motherboard 8 of the monomedel module 4e and on the underside of the motherboard 8.

All other components, arrangements and means-effect relationships are analogous to the description of the Figures 3A and Figure 4A of the single detector module 4.1.

A third embodiment of the mono detector module 4.1 according to the invention (with 2 industrial connectors 39) in a "mini" size, namely the mono detector module 4.1i is shown in FIG Figure 3C in the side view and in the

Figure 4C shown in top view.

That in the Figures 3C and 4C Mono detector module 4.1i shown has the same functionality as that in the Figures 3 and Figure 4 shown mono detector module 4.1 (with 2 industrial connectors 30), but its dimensions are much smaller, the so-called "mini" overall size.

For reasons of manufacturing economy, to increase the reliability and in particular to further miniaturize the mono-detector modules 4.1, the mono-detector module 4.1i (according to FIG Figure 3C and

Figure 4C ) the separator 10 is also moved into the base 9, so as to realize a flat design. In this embodiment, the base 9 is "mini" mounted directly on a round (cylindrical) lower housing part 6.

The upper housing part 7 can in the embodiment "mini" (according to Figure 3C and Figure 4C ) as with the duo detector module 3i (according to the Figure 1C and Figure 2C ) do not apply. The upper part 7 of the mono detector module 4.1i, which has been omitted, as well as the standardized lower part 6 of the housing lead to improved overall economy and further miniaturization of the single detector module 4.1.

According to Figure 4C The industrial connectors 30 for the signal input 11 and the signal output 12 are directly integrated into the lower housing part 6 on a flange provided for this purpose.

The lower housing part 6 is fastened as in FIG Figure 3C shown, via a screw or clip connection 26 directly on the motherboard 8, with the bottom of the motherboard 8, as with all Designs of the detector modules according to the invention one or more adhesive element (s) 17 is / are attached.

The motherboard 8 has in the Figures 3C and Figure 4C illustrated embodiment, in contrast to the embodiment according to Figure 3A and Figure 4A , no longer the function of the electrical connection between smoke detector 2.1 and isolator 10, but only the constructive function of the attachment.

All other components, arrangements and means-effect relationships correspond to the description of the single detector module 4.1 according to that in the

Figure 3A and Figure 4A illustrated embodiment.

In the Figure 5B are in the side view and in the Figure 6B the plan view shows a second embodiment of the mono detector module 4.2 according to the invention (with 3 industrial connectors 30), namely the mono detector module 4.2e, which has a medium, a so-called "medium" overall size.

In principle, the Monomedmeldermodul 4.2e has the same functionality as that in the Figures 5A and 6A Mono detector module shown 4.2.

For reasons of manufacturing economy and increased reliability, in contrast to the embodiment according to the Figures 5A and 6A an additional isolator 10 is installed in the detector base 9.

This has the advantage that even in the event of a line interruption and / or short circuit between smoke detector 2.1 and smoke detector 2.2 or in the event of the failure of one of these two smoke detectors 2, the rest of the ring bus participants are activated and the ring bus 18 remains in operation.

In this exemplary embodiment, the detector base 8 has a somewhat higher design and is mounted directly on the housing base 16 by means of a screw or clip connection 26.

The motherboard 8 in the Figures 5B and 6B has shown Monomedmeldermodule 4.2e, in contrast to that in the Figures 5A and 6A Mono detector module 4.2 shown, no longer the function of the electrical Connection between smoke detector 2.1 and isolator 10, but only fulfills the constructive function of the attachment.

For this purpose, the base 8 on the monomedel module 4.2e, on the one hand, the base 8 and, on the other hand, the adhesive element (s) 17 are attached to the underside of the base board 8.

All other components, arrangements and means-effect relationships correspond to the description of the Figures 5A and 6A of the single detector module 4.2.

The designation “arrangement of the mono-detector modules 4e in pairs” means that the individual mono-detector modules 4.1e and 4.2e are connected / arranged in pairs with one another.

The Figure 5C (Side view) and the Figure 6C (Top view) show a third embodiment of the mono detector module 4.2 according to the invention (with 3 industrial connectors 30), namely the mono detector module 4.2i in a small, a so-called "mini" size.

In principle, this mono detector module 4.2i of the small, the so-called "mini" size has the same functionality as the large one in the

Figures 5A and 6A illustrated embodiment of the single detector module 4.2.

For reasons of manufacturing economy, but in particular also to increase the reliability and for the purpose of further miniaturization of the mono-detector modules 4, this was in the Figures 5C and 6C Embodiment shown, the mono detector module 4.2i, an additional isolator 10 also integrated into the flat base 9, which in this embodiment is mounted directly on a round (cylindrical) lower housing part 6.

The additional isolator 10 has the advantage that even in the event of a line interruption and / or short circuit between the smoke detector 2.1 and the smoke detector 2.2 or in the event of the failure of one of these two smoke detectors 2, the rest of the ring bus subscribers are activated and the ring bus 18 continues to operate Operation remains.

The upper housing part 7 can in this embodiment, as well as in connection with Figure 1C described duo detector modules 3.2i.

The "omitted upper housing part 7" as well as the standardized lower housing part 6 lead to an improved overall economy and to further miniaturization of the mono detector module 4.2i.

The Figure 6C shows that the industrial connectors 30 for the signal input 11, the signal output 12 and the external signal output 13 are arranged directly on the lower housing part 6.

The lower housing part 6 is fastened directly on the motherboard 8 by means of a screw and / or clip connection 26. On the underside of the motherboard 8, as in all embodiments of the above-described mono- and and duo detector modules according to the invention, there are again one or more adhesive elements 17 attached.

The motherboard 8 has in this, in the Figure 5C illustrated embodiment, in contrast to that in the Figure 5A shown mono detector module 4.2 no longer the function of the electrical connection between smoke detector 2.2 and isolator 10, but only the constructive function of the attachment.

All other components, arrangements and means-effect relationships are analogous to that in the Figure 5A and Figure 6A described single detector module 4.2.

The designation "arrangement of the mono-detector modules 4i in pairs" means that the individual mono-detector modules 4.1i and 4.2i are connected / arranged in pairs with one another.

The Figure 7 now shows an inventive arrangement for monitoring and early fire detection for fire and / or explosion-prone vessels and / or housing in a first variant.

In this schematic representation, the arrangement of a dual detector module 3 in a vessel 1 (here, for example, 19 "IT rack) with a vertical cooling air flow 32 from bottom to top (for example from a double floor 33) is shown.

Alternatively, the duo-alarm module 3e or the duo-alarm module 3i can also be used in this arrangement.

For this case of cabinet cooling, the ideal installation location of the dual detector module 3 on the roof of the cabinet is because here the entire cooling air flow 32 of the vessel 1 comes together and a possible fire can be detected quickly and safely at an early stage (optimal arrangement).

The installation location of the dual detector module 3 can therefore be optimized and selected quickly because the design (acc. Fig. 1A and 2A ), an adhesive base 17 and an electrical connection (ring bus 18) via industrial connector 30.

The installation location is not defined by certain design constraints due to pipes, as is common in smoke aspiration systems.

An example is 1 in Figure 7 also a (double) display module 20 (see also Figure 11 ) and a separate external signal generator 27 are arranged. Depending on the requirements of the user, they are used for remote display for the main alarm (external signal transmitter 27) or, if necessary, with the help of the (double) display module 20 for local display, provided with additional information about any pre-alarm of smoke detectors I 2.1 and smoke detectors II 2.2 in the dual detector module 3 or in the paired single detector module 4.1 and 4.2. The (double) display module 20 is installed in a typical 19 "frame 34 (19 inch frame). The second display field can be used for signaling for a second duo detector module 3, or is covered with a blind plate 29 when not in use (Double) display module 20 acoustic, local alarm as well as other functions (e.g. deletion) via integrable actuators 22 (see Fig. 12 ).

The Figure 8 shows the structure of the arrangement according to the invention for monitoring and early fire detection for fire and / or explosion-prone vessels and / or housing in a second variant the arrangement of dual detector modules 3 in vessels 1, which are arranged in a so-called cold aisle 35 for the purpose of optimal cooling air flows 32.

The cooling air flow 32 flows horizontally through the vessels 1 (IT racks).

In this application, a vertical arrangement of two dual detector modules 3 per vessel 1 is optimal, since in this way defined monitoring zones 36 can be monitored quickly and reliably for fire parameters.

Alternatively, duomed alarm modules 3e or duo alarm modules 3i can also be used in this arrangement.

The simple and secure fastening of the dual detector modules 3 by means of the adhesive elements 17 on the inner side walls of the vessels 1 allows the vessels 1 to be monitored to be equipped quickly and flexibly.

The monitoring of the vessels 1 (IT racks) which has been common in the prior art in the cold aisle 35 by means of smoke suction pipes (smoke suction principle) arranged horizontally behind the racks in the area of the cooling air outlet is significantly improved by the solution according to the invention, so that by means of In the solution according to the invention, the direct monitoring of each individual vessel 1 (rack's) in the cold aisle 35 is ensured in two or more zones by means of two or more, directly measuring, dual detector modules 3.

In the case of the horizontal arrangement of the smoke suction pipes on the air outlet side, which is common in the prior art, behind the racks, they only record one (tiny) partial air flow per vessel 1 (rack); if there are several racks standing side by side, this becomes proportional to the number of racks diluted.

In the event of a fire, the affected object cannot be detected, or can be detected much too late, since the air thinning results in a corresponding proportional delay.

An initiated deletion or shutdown is necessarily slower and the potential damage is much higher.

Due to the (selectively not possible) complete shutdown or deletion, the damage increases extremely. Intervention that is too late further increases the damage.

The economic advantages resulting from the use of the solution according to the invention are therefore enormous in the event of a fire.

The problem of the relatively inaccurate detection by means of smoke aspiration systems is further aggravated in the case of arrangements with external forced ventilation in the cold aisle 35 because, depending on the equipment, there can be air pressure differences per rack (vessel 1) on the rear sides of the rack, which then differ from the calculated air volumes allows the individual smoke suction openings of the smoke suction pipe common to the racks to flow.

This effect makes detection with smoke aspiration systems in vessels 1, in particular with forced ventilation, even more unsafe. The way out of individual monitoring with one smoke aspiration system per vessel generally makes the arrangement extremely expensive and is only used in exceptional cases.

The arrangement according to the invention can even be used to monitor vessels 1 in which, for example, high internal pressure (e.g. clean rooms, monitored telecommunication housings etc.) smoke suction systems cannot be used due to the pressure differences.

Because of their size and high need for maintenance, this is also not possible in the vessel 1 itself.

Here, too, the early fire detection solution according to the invention shows its many advantages as well as its essential advantages.

This also includes the equipment, as well as maintenance and service, which, due to the inexpensive modular principle (only sensors and simple displays in the object to be monitored, central power supply and central control by evaluation unit 19 ( Figure 13A , Fig. 13 B) ) from a certain number of monitoring points (approx. 3 to 5) is significantly less expensive than all of the solutions described in the prior art.

The almost linearly increasing price per piece (selective measuring point) for smoke aspiration systems, depending on the number of pieces used, increases in the case of the inventive arrangement for early detection of fire, in the form of an e-function, initially falling strongly non-linearly, for larger quantities it is approximately the same permanent price per measuring point.

The price differences for a larger number of measuring points are therefore significant.

The higher level of equipment with the early fire detection according to the invention, which is possible with the same financial outlay, also significantly increases safety. This is an essential further aim of the arrangement for early fire detection according to the invention.

Another important advantage of the solution according to the invention of the individual monitoring of vessels 1 is that, compared to smoke aspiration systems, the low maintenance expenditure per vessel 1 to be individually monitored is because this system on site essentially comprises only detector modules (mono detector modules 4 (ie also 4e and 4i) and duo detector modules 3 (ie also 3e and 3i)) or local signaling is required. The maintenance-intensive components of smoke extraction systems such as intake pipes, filters, fans, fan controls, local sensor evaluation and monitoring, local energy supply and emergency power supply etc. are eliminated for each detection location.

For these reasons, not only the installation, but also the maintenance and the significantly better energy balance of the solution according to the invention are economically more favorable in comparison to other, commercially available, but in particular to smoke suction systems.

In addition, high maintenance costs necessarily reduce availability.

The Figure 9 shows a third example of the arrangement of the solution according to the invention for monitoring and early fire detection for fire and / or explosion-prone vessels and / or housing.

In a vessel 1 (19 "rack), which in this case works with integrated forced air cooling with fan 37 in a closed circuit, two paired mono detector modules 4 (4.1 and 4.2) are installed diagonally opposite each other so that each mono detector module 4 (4.1 and 4.2) receives a portion of the representative air volume of the housing 1 in a short time (forced ventilation and blower 37) and can therefore detect smoke particles for early fire detection.

Alternatively, mono-detector modules 4e or mono-detector modules 4i can also be used in this arrangement.

This arrangement of the mono detector modules 4 (4.1 and 4.2) allows an integral assessment of the entire air content of the vessel 1 and thus enables an even higher level of security against false alarms, since not the air volume at a certain point (or approximately point, as with the duo detector module 3, in which the sensors (Smoke detectors 2) are mounted approx. 20 cm apart) but is detected as an integral of the entire vessel 1. This arrangement is particularly recommended in cases where the highest demands are placed on false alarm security (e.g. when switching off or extinguishing in vessel 1 / rack, sometimes with extreme costs!). For quick visibility of the affected vessel 1 (rack) in the event of a fire, a local external signal transmitter 27 is (for example) mounted on the vessel 1 (rack).

The course of the ring bus 18 is also indicated by way of example. The separate routing of the connecting cable 31 of the ring bus 18 in the vessel 1, as well as between the vessels (in the room / in rooms) has the advantage in the event of damage that usually only one cable can be affected.

This is an additional security feature of the ring bus topology.

The Figure 10 shows a further arrangement of the inventive solution for monitoring and early fire detection for fire and / or explosion-prone vessels and / or housing with an exemplary fourth variant.

Here, in a vessel 1 (closed housing, for example low-voltage main distribution, degree of protection IP 54 - splash-proof), a dual detector module 3 is arranged in the upper region of the vessel 1 in such a way that a cooling air flow 32, which arises as a result of natural convection (heating-cooling), always does that Duo detector module 3 reached.

Alternatively, the duo-alarm module 3e or the duo-alarm module 3i can also be used in this arrangement.

In the event of detection, the external signal transmitter 27, which can be easily connected to the dual detector module 3 via external signal output 13, signals an alarm state on this vessel 1, so that intervention can be carried out quickly. This example clearly shows that the solution according to the invention can also be used on many small vessels (which are just as important for the overall function in the data center, for example).

In this exemplary embodiment, the use of a smoke aspiration system would not be possible because the degree of protection (IP 54 - splash-proof) is hardly feasible or moreover not affordable.

In this application, too, the great advantages of the solution according to the invention come into play, i.e. Only detector modules (e.g. duo detector modules 3) and absolutely necessary additional devices (e.g. external signal transmitter 27 on site) are connected to the monitoring location, connected by an interruption-resistant ring bus 18, which only requires electrical cables that are easy to install and change.

As already in connection with Fig. 8 described, the overall security for a complex device to be monitored (eg data center, control room, etc.) increases significantly with an increasing degree of surveillance of many individual objects, to which the inventive arrangement of early fire detection makes a significant contribution.

In summary, it can be stated that a significant advantage of the arrangement according to the invention for early fire detection is that, due to the compact design and size of the detector modules (for example duo detector module 3 and mono detector module 4), they are located directly at the detection site in most of the cases that occur in practice (concerns size, type of ventilation, ambient conditions etc.) can be used (mass use), deliver better detection results than comparable systems on the market and significantly increase the security of complex systems (e.g. data centers) through extensive use.

The Figure 11A shows the structure of a (double) display module 20 according to the invention used in the arrangement according to the invention for monitoring and early fire detection for fire and / or explosion-prone vessels and / or housings in the form of a 19 "insert (19 inch insert), which among other things in the front area contains two display fields 23, each of which contains three signal lights (LED) on the front, the LED signal displays 24, with which the most important operating states of the associated detector module (e.g. a duo detector module 3 or two interconnected mono detector modules 4) can be displayed The alarms displayed by means of the LED signal displays 24 are initially pre-alarm sensor 1 24.2 and pre-alarm sensor 2 24.3. The displays light up when one of the two smoke detectors 2 (2.1 or / and 2.2) of a detector module (for example the duo detector module 3 or the mono detector module) 4) the (individually) set pre-alarm threshold has been reached or exceeded Optionally, together with the local visual display of the pre-alarms 24.2 and 24.3, an acoustic signal transmitter 25 located in the 19 "housing of the display module 20 can also be used. Figure 12A , head for.

The third signal light, the third LED signal indicators 24, on the display field 23 signals the main alarm 24.1 (fire alarm). Their lighting can also be linked to a local acoustic alarm of the signal generator 25. The 3 most important signals are controlled via a ring bus-compatible actuator module 22 ( Figure 12A ) that the control commands previously from the evaluation unit 19 ( Figure 13A ) had received. The evaluation unit 19 in turn has previously that of the smoke detectors 2 (smoke detectors I 2.1 and smoke detectors II 2.2) of a detector module (for example duo detector module 3). transmitted data of fire parameters detected in vessel 1 obtained and evaluated. In addition to the local alarm on the monitored vessel 1, the evaluation unit 19 also outputs an alarm relay 38 to a point of assistance.

If necessary, the actuator module 22 can carry out further switching operations in the vessel 1 both in the case of a pre-alarm and in the case of a main alarm (e.g. switching off the energy and ventilation, switching on the extinguishing, etc.) with the aid of further freely programmable outputs.

Does the vessel contain e.g. two duo detector modules 3, the described second display field 23 of the display module 20 is occupied if necessary, in which the second actuator module 22 is then also fitted.

If the second display field 23 is not required, the free module space is covered with a blind plate 29.

The display module 20 has the advantage that alarms (pre-alarms and main alarms) can be displayed locally on the 19 "vessel (19 inch vessel), regardless of where the detector modules (eg mono detector module 4 or duo detector module 3) are installed in vessel 1 and therefore not This is a significant advantage, since many of the systems on the market have combined sensors, evaluation, power supply and signaling in one module, and therefore (eg due to a lack of visibility and accessibility) only in certain, but not always optimal places get installed.

The Figure 12A shows the structure of a display module 20 according to the invention in the form of a 19 "insert in a plan view.

The arrangement of the two actuator modules 22, the two (acoustic) signal transmitters (25) and the position of the ring bus inputs 11 and ring bus outputs 12 and another possible industrial connector 30 for e.g. other circuits (e.g. an extinguishing control).

Furthermore, the arrangement of the signal displays 24, which are subdivided into main alarm 24.1, pre-alarm sensor 1 24.2 and pre-alarm sensor 2 24.3, can be seen. Another special advantage, which in the view of Fig. 12 visible, is the use of a standardized 19 ", 1 U slot for the display module 20.

This enables quick assembly / disassembly in the commercially available, widely used 19 "vessel systems, and the low height of only 1 U (44.4 mm) does not result in space problems.

The easy connection via the industrial connector 30 also saves time and long-term stability.

A further embodiment for the display module 20, namely that of a deletion display module 43, is in the front view in FIG Figure 11B , and in the top view in the Figure 12B shown.

It is preferably used when, in a vessel 1 to be monitored, an extinguishing device is switched on, if necessary, and / or the supply energy and / or the cooling air flow 32 is to be switched off.

In this embodiment, the arrangement according to the invention for monitoring and early detection of fire for several fire and / or explosion-prone vessels (1) and / or housing takes on switching and optical actions, in particular the initiation of an extinguishing process.

In addition to early fire detection, the function of initiating an extinguishing process, particularly for vessels with rapidly progressing fire processes, is of great importance.

The initiation of the extinguishing process in only one, the affected vessel is possible as a result of a very precise detection, since the smoke sensors available in the prior art can detect air turbidity of 0.02 to 3% / m very precisely, which then means very much by means of the arrangement according to the invention Exactly depending on the size of the air turbidity achieved, a pre-alarm, for example from 0.02% / m, or when the air turbidity reaches 3% / m, the fire alarm can be triggered and the extinguishing process can be initiated. In this case, by means of the arrangement according to the invention, the power supply and the ventilation of the affected vessel can also be switched off immediately before the extinction in the vessel begins.

With the arrangement according to the invention, in addition to selective early detection of fire, selective fire fighting by selective shutdown and / or extinguishing can also be implemented in practice.

In the event of a fire, this means enormous cost savings, as usually the entire room (with all vessels) is no longer, as is usually the case today, e.g. must be flooded with extinguishing gas.

The flooding of the entire room always entails high follow-up costs due to total shutdown, high extinguishing agent costs and often considerable risks to people, such as CO ₂ extinguishing.

The delete display module 42 is likewise accommodated in a 19 "insert (19 inch insert) and is equipped with two display fields 23. Each of the two display fields 23 is equipped with four signal displays 24.

One of the four signal displays 24 (24.1, 24.2, 24.3 and 24.4) signals operation (green), pre-alarm (yellow), fire alarm (red) and switch-off / extinguishing (blue).

Each display field 23 can display the most important operating states of an assigned duo detector module 3, duo detector module 3e, duo detector module 3i, or of two mono detector modules 4, mono detector modules 4e or mono detector modules 4i, as well as any switching processes that have been triggered (for example, switching off / deleting).

The Figure 12B shows the equipping of a special extinguishing display module 43 with one actuator module 22 per display field 23.

In this embodiment, the actuator module 22 in the right display field 23 of the top view therefore controls according to Figure 12B , in addition to the signal displays 24 also the local extinguishing control 41. Instead of activating a local extinguishing control 41, the output of an actuator module 22 can also be used eg the energy supply and / or the cooling / ventilation of a vessel can be switched off.

The actuator module 22 in the left display field 23 of the top view contains an actuator module 22 which, for example, only controls the signal displays 24 for a duo detector module 3i, for example, or switches on corresponding local acoustic signals via signal transmitters 25.

The signal display 24.4 which is not required is replaced by a blind plate 29. The actuator modules 22 are located on the common ring bus 18 of the arrangement according to the invention for monitoring and early detection of fire for vessels and / or housings at risk of fire and / or explosion, and also each have a disconnector 10, the function of which has been described several times.

The deletion indicator module 43 can optionally be fully equipped with actuator modules 22 and signal indicators 24 or only partially. In the case of partial assembly, the openings which are not required are closed with blind plates 29.

All other components, arrangements and properties are analogous to the description for Figure 12A .

The Figure 13A shows the structure of an arrangement according to the invention of dual detector modules 3, single detector modules 4 (4.1 and 4.2) which are partially additionally equipped with actuator modules 22 or external signal transmitters 27 or control them, together with the central evaluation unit 19 on a ring bus 18.

Other ring bus participants are a separate actuator module 22, a remote control panel 21 and a display panel 23 assigned to a mono detector module 4 with actuator module 22. The evaluation unit 19 takes over the central functions for all participants of the ring bus 18: power supply, transmission and reception of signals from the Participants, signal evaluation, processing, storage and forwarding, emergency power supply, communication with external systems 39 (e.g. management systems, fire alarm systems etc.) and the alarm message 38 eg to a person providing help (eg operating personnel, fire brigade). The mains connection 28 (230 V) takes place centrally on the evaluation unit 19.

The remote control panel 21 and an external actuator module 22 can be located anywhere in the ring bus 18. The remote control panel 21 has the full functionality of the control panel of the evaluation unit 18 and can advantageously also be remote from it, e.g. installed in a control room or in a gate. This enables convenient, quick and complete control of all alarms and operating states of the overall system at any point. As a participant of the ring bus, the control panel 21 has a isolator 10, which also develops its positive properties in the event of a fault (short circuit, interruption).

This also contains the external actuator module 22, which is shown in the circuit example Figure 13A is located externally on the ring bus 18 and can perform any switching operations (eg activation of voice alarms etc.). Furthermore, system-internal external sensor modules 40 (also with isolator 10) can be arranged on the ring bus 18, which allow a substantial expansion of the functionality of the arrangement according to the invention for early detection of fire.

What is meant by this is the possibility of acquiring additional input signals via an external sensor module 40 (for example of motion detectors, contacts, video systems, access controls, subsystems of all types, etc.) and their processing and storage in the evaluation unit 19. The evaluation unit 19 not only manages centrally all participants of the ring bus 18, it also has a management system with which all ring bus participants can be spatially displayed and managed on a remote screen. The management system can be connected to the interface for external systems 39. The evaluation unit 19 can also be networked with other subsystems, for example fire alarm systems, etc., via the interface for external systems 39. Another positive performance feature of the arrangement according to the invention for early detection of fire in vessels 1 is the possibility of monitored (continuous monitoring) and stable (because Interface for alarm transmission 38 wired with function maintenance. Thanks to the function maintenance function (eg E 30), the connecting cable can withstand fire for 30 minutes when it is fully functional; any other interruption is immediately recognized as an alarm.

The Figure 13B shows the arrangement according to the invention for monitoring and early detection of fire for fire and / or explosion-prone vessels and / or housings in a basic illustration of a ring bus segment with the use of dual detector modules 3e, dual detector modules 3i, single detector modules 4e (4.1e and 4.2e) and single alarm modules 4i ( 4.1i and 4.2i) and a deletion display module 43.

All other components, arrangements and properties are analogous to the description for Figure 13A .

The Figure 14 shows the structure of an arrangement of components according to the invention in a stylized ring bus 18.

Here again a number of advantages of this arrangement according to the invention for monitoring and early detection of fire in vessels become clear. This includes a clear ring structure, which does not have the disadvantages of tree structures such as confusion (especially in the case of documentation that is not maintained (in practice)), no resistance to interruption, restrictions in upgradeability, decentralized power and emergency power supply, etc., full or partial maintenance of the functionality of the ring bus 18 in the event of short-circuit and interruption by using isolators 10 in each bus user. The evaluation unit 19 detects short circuits or interruptions in the ring bus 18 and selectively switches the smallest possible part of the bus participant off or on via isolator 10, the two remaining ring halves are supplied from both sides of the ring until the fault has been rectified (operating voltage, data stream), all other participants remain fully functional.

The inventive use of the two-detector dependency in connection with the use of detector modules according to the invention (eg Mono-detector modules 4 and duo-detector modules 3) significantly reduce false alarm security.

Advantages of the solution according to the invention are a very good energy balance, since central power and emergency power supply takes place only via evaluation unit 19, simple and economical maintenance and service (clear structure, no decentralized power supplies and emergency power batteries, which always pose a risk in the long term), significantly lower costs per individually monitored vessel 1, because only sensors and simple signaling on site, everything else is arranged centrally, the largely separate routing of supply and discharge in the ring bus 18, which means greater availability in the event of damage (e.g. Fig. 14 / Fig. 15 ) shows that the evaluation and management of all process variables takes place centrally in the evaluation unit 19 and on remote control panels 21. Any installation location of the evaluation unit (eg in a control room) can further increase system security.

The arrangement of components for early fire detection according to the invention results, also in particular due to the arrangement in the ring bus 18, in significant improvements in comparison to conventional, commercially available systems in this area. At significantly lower costs per individually monitored vessel, the quality of monitoring per vessel and for the overall system increases enormously. At the same time, there is a significant improvement in system security.

As shown by way of example, the position of the evaluation unit 19 is in the vessels 1 in vessel B ( Figure 15 ) possible, but also, as already described, can be installed anywhere outside the surveillance area.

The Figure 15 shows a possible structure of the monitored vessels according to the invention.

Especially in this spatial arrangement, which in principle is the stylized structure of Fig. 14 the advantages of the ring bus structure already mentioned, the simple and complete equipping of vessels 1 of all sizes, arrangement and ventilation forms with detector modules (eg dual detector modules 3 and Mono detector modules 4), the possibility of mounting remote control panels 21 and actuator modules 22 and the increased security shown by the individual routing of the ring bus cables. The considerable advantages that a system that is homogeneous and clearly structured by the monitoring principle also offer Fig. 15 clarified again pictorially.

As explained in the above-mentioned exemplary embodiments, the solution according to the invention with special detector modules according to the invention (duo detector module / pair of mono detector modules) and their arrangement according to the invention succeed in eliminating the disadvantages described in the prior art.

For this purpose, the detector modules according to the invention can be varied, i.e. individually, in an optimal position to a possible ignition source, quickly, tool- and chip-free at optimal detection locations in the object to be monitored.

The assembly is also carried out on the basis of the module concept according to the invention with smoke / gas sensors mounted on / in the carrier / housing, with quick connection via plug connectors, and tool-free, screw-free and chip-free by means of detachable joint connections.

The detector modules themselves do not contain any complex infrastructure, but only one or two smoke detectors and are therefore very inexpensive.

Due to the small size and the relatively low price, the detector modules can still be used economically in (almost) all properties and in large numbers.

The somewhat more complex evaluation unit is only available once for a large number of detector modules in a complex to be monitored.

According to the invention, the detector modules are wired relatively inexpensively and very reliably only with electrical lines in a ring bus topology.

The arrangement according to the invention for monitoring and early detection of fire for several fire and / or explosion-prone vessels and / or housings therefore offers a reasonable plant cost optimal alternative to the currently in the prior art, for example in the switching u. Server cabinets from data centers (e.g. at banks and the like), smoke detectors used with which the switching and. To provide server cabinets with pneumatic pipelines connecting the evaluation unit, which at the same time provide a much more cost-effective and precise, as well as also false alarm-proof, selective monitoring of a significantly higher number of "measuring points" (eg server cabinets) using only one evaluation unit, with a significantly reduced manufacturing , Assembly, maintenance and repair work, high flexibility and high availability, guaranteed even during the maintenance work but also during the expansion work of the overall system.
