     FIELD OF THE INVENTION 
       [0006]    The invention relates to a system for building automation according to the preamble of claim  1  and a method for building automation according to the preamble of claim  14 . 
       BACKGROUND OF THE INVENTION 
       [0007]    Recently building automation, thus an entirety of monitoring, control and optimization devices, in particular building automation, thus an increase of living comfort for inhabitants of private buildings is considered more and more relevant. Considerable efforts are being made to provide suitable solutions, wherein it is an object to include as many pieces of equipment and similar building elements in a common network in order to be able to jointly control the building elements. 
       BRIEF SUMMARY OF THE INVENTION 
       [0008]    Thus it is an object of the invention to further improve building automation. 
         [0009]    The object is achieved by a system for building automation including at least one smoke or fire detector including a connection side; at least one adapter that is coupleable with the at least one smoke or fire detector and that includes a front side, a backside and a lateral portion connecting the front side and the backside; and at least one functional unit which is connected or connectable with the at least one adapter, wherein the at least one smoke or fire detector is arranged with the connection side on a front side of the at least one adapter and the at least one functional unit extends with respect to the connection side of the at least one smoke or fire detector below the at least one smoke or fire detector about the lateral portion of the at least one adapter in a connected condition of the at least one smoke or fire detector, the at least one adapter and the at least one functional unit, and wherein the at least one smoke or fire detector, the at least one adapter and the at least one functional unit are mechanically connected in the connected condition of the at least one smoke or fire detector, the at least one adapter and the at least one functional unit. 
         [0010]    The object is also achieved by a method for building automation, wherein at least one smoke or fire detector that includes a connection side is coupled with at least one adapter that includes a front side, a backside and a lateral portion connecting the front side and the backside, so that the connection side of the at least one smoke or fire detector is arranged on the front side of the at least one adapter, and wherein the at least one functional unit is being connected with the at least one adapter so that the at least one functional unit extends with respect to the connection side of the at least one smoke or fire detector below the at least one smoke or fire detector about the lateral portion of the at least one adapter in a connected condition of the at least one functional unit, the at least one smoke or fire detector and the at least one adapter, wherein the at least one functional unit, the at least one smoke or fire detector and the at least one adapter are mechanically connected in the connected condition of the at least one functional unit, the at least one smoke or fire detector and the at least one adapter. 
         [0011]    Advantageous embodiments are provided in the dependent claims. 
         [0012]    The inventors have found that the object can be achieved in a particular simple and effective manner by improving upon smoke or fire detectors typically already provided in buildings and expanding their functionality. Thus, no additional installation space is required but the space required for the smoke and fire detectors is used in an optimum manner which benefits overall esthetics of the building. 
         [0013]    Accordingly the building automation system according to the invention includes at least one smoke and/or fire detector, at least one adapter which is coupleable with the smoke or fire detector and one or more functional units that are connected or connectable with the adapter. For example a typical smoke detector can be supplemented by illumination devices and/or motion detectors. 
         [0014]    The functional units can thus either be integrated in the adapter or connectable with the adapter. Thus the connection can be provided mechanically and/or for data transfer and/or for energy transfer directly with the adapter or also indirectly, this means with one or plural other devices connected there between. 
         [0015]    In this context “connecting” or “connection” does not only mean mechanical or data connections but also relates to a direct process of transferring information or parameters. 
         [0016]    A mechanical and/or communicative and/or energetic connection with the smoke and fire detector can thus be provided but is not required for the instant invention since advantageous effects can also be achieved without this connection. 
         [0017]    The adapter can merely thus merely be a mechanical adapter or also an adapter with an energy and/or communication interface to the smoke and fire detector. 
         [0018]    In this context it is advantageous when at least a second adapter is provided which is adapted to provide a second interface for the functional unit or other house hold equipment. Thus an adaptation to any type of smoke or fire detector and functional unit and household equipment can be provided in a particularly simple and cost effective manner, since the interfaces of smoke and fire detectors and household equipment are typically provided as proprietary interfaces. 
         [0019]    In an advantageous embodiment the one or plural functional units are provided as modules. Then the functional scope of the smoke and fire detectors can be expanded particularly easily. 
         [0020]    A particularly advantageous embodiment of the functionality is provided when the functional unit implements one or plural properties from the group motion detector, temperature sensor, video capture, audio capture, illumination, brightness sensor, humidity sensor, CO 2  sensor, CO sensor and similar. 
         [0021]    Advantageously a first control and/or processing device is provided which is advantageous provided as the adapter. Then the expanded functional scope can be used in a more comprehensive manner. Furthermore no additional central control and processing devices are required which further reduces space requirement. 
         [0022]    It is particularly useful in this context when the first control and/or processing device
   a) controls the smoke or fire detector and/or the functional unit, and/or   b) reads out at least one property of the smoke and fire detector and/or of the functional unit.   
 
         [0025]    The adapter is advantageous provided as a communication device, in particular as a gateway. 
         [0026]    When at least a data connection is provided with at least one piece of household equipment advantageously from the group including automatic door opener, illumination device, motion detector, vehicles, television sets, freezers, dish cleaners, heating systems, stoves, coffee makers, fire places, air conditioners, stove tops, refrigerators, microwaves, blenders, music play back devices, smoke and fire detectors, radios, lawn irrigation systems, cleaning devices, bathroom equipment, saunas, locks, umbrellas, sprinkler systems, vacuum cleaners, swimming pools, monitoring devices, blinds, washers, dryers, water heaters, meteorological stations, whirlpools and similar then linking plural building elements described in the application “Method and system for building automation” owned by Applicant and filed on Nov. 21, 2014 can be implemented in a particularly simple manner. The content of this application is incorporated by reference so that smoke and fire detectors, functional units and the household equipment recited supra are “building elements”. 
         [0027]    “Building elements” are thus not only pieces of equipment that are permanently connected to the building but also equipment that is mobile and only located in the building temporarily. Thus, a building is not only a house or a similar object but also a plot of land and improvements that are associated with the object. 
         [0028]    In another advantageous embodiment it is provided that the first control and/or processing device is adapted to collect and/or process information from connected pieces of household equipment, the smoke and fire detector, and/or the functional unit and/or to forward the information to at least one second control and/or processing device. 
         [0029]    It is particularly advantageous when the functional unit is configured coupleable to the first control and/or processing device and/or the adapter. This is a data connection and/or energy connection where no direct access to the smoke or fire detector is performed. 
         [0030]    It is furthermore advantageous when the functional unit extends in connected condition about the first control and/or processing device and/or the adapter, wherein the functional unit is advantageously configured circular ring shaped. This embodiment facilitates a particularly esthetic appearance. Furthermore the smoke and fire detector remains compact. Furthermore the functionality can be expended in a particularly simple manner without interfering with the function and safety requirements of the smoke and fire detector. 
         [0031]    In another embodiment it is provided that plural functional units are configured pluggable into each other and/or that the functional unit includes a base element into which modules implementing one or plural properties are pluggable. This facilitates an uncomplicated and expandable configuration of the functionality. Thus, the functional units can mesh with each other wherein the functional units are configured e.g. as ring elements with meshing teething which provide a mechanical clip function. 
         [0032]    Integrating and augmenting the building automation system is performed in a very simple manner when the first control and/or processing device is associated with an address that is associable in a unique manner in a communication network, wherein the address is in particular a MAC-address in an IP network. 
         [0033]    This is also facilitated in that the first control and/or processing device includes a network interface to provide communication with additional network units, advantageously with a second control and/or processing device, wherein the network interface is based in particular on at least one protocol from the group blue tooth, Wi-Fi, ZigBee, Z-Wave, Ethernet, WLAN and similar. Then communications are provided in a particularly simple and safe manner. 
         [0034]    Another advantageous embodiment provides that 
         [0035]    a) the first control or processing device and/or the adapter is autonomously provided with energy for implementing a minimal mode using at least one energy supply from the group including battery, accumulator and solar module in order to read out at least one property of a connected device in order to monitor the device and to forward respective errors to a provided error reporting unit, and/or that 
         [0036]    b) the first control or processing device, and/or the adapter is provided with external energy for implementing a maximum mode, for example by PoE (power over Ethernet), Mini-USB interface or 110-220 V supply. 
         [0037]    In both cases a loading of the energy supply of the smoke or fire detector that is to be permanently provided for safety reasons is effectively avoided. Furthermore it can also be provided that the smoke or fire detector is provided with energy through the first control and processing device and/or the adapter. This can also be provided in addition to a regular energy supply of the smoke or fire detector. 
         [0038]    For safety reasons an external power supply for an energy intense functional unit, like e.g. illuminant or for a ZigBee interface can be provided. For example the adapter can be provided with a corresponding external power supply in order to cover the energy requirement. This adapter can then also provide e.g. the smoke detector with energy. 
         [0039]    For smoke and fire detectors, however also other safety aspects have to be considered. Thus, for example no external heat introduction may be performed by the lighting system in order not to impair its function. Therefore the functional unit configured for lighting shall be provided with low load LEDs and a direct light radiation onto the smoke detector shall be prevented. 
         [0040]    When the smoke and fire detector is data connected it can be provided for example that in addition to its standard alarm tone the following is provided: 
         [0041]    1. lights turn on, flash or change color upon an alarm, and/or 
         [0042]    2. a public announcement instructing everybody what to do and not only a siren sounds upon an alarm and/or 
         [0043]    3. A video image of the room is captured upon an alarm, 
         [0044]    Independent patent protection is also claimed for the method according to the invention for building automation, wherein at least one smoke and/or fire detector is coupled with at least one adapter, wherein one or more functional units are connected with the first adapter or are going to be connected with the first adapter. 
         [0045]    Advantageously the building automation system according to the invention is used for the method. 
         [0046]    According to the invention features of the system can be used as features for the method and features of the method can also be used as features for the system when nothing else is stated. 
         [0047]    Furthermore unless stated differently all features can be combined with each other at will. 
     
    
     
       BRIEF DESCRIPTION OF THE DRAWINGS 
         [0048]    The invention is subsequently described in more detail with reference to an embodiment illustrated in a drawing figures. Further details of the invention can be derived from the subsequent description of the embodiments in combination with the patent claims and the appended drawing figures, wherein: 
           [0049]      FIG. 1  illustrates the system according to the invention in an advantageous embodiment; 
           [0050]      FIGS. 2A, 2B  illustrates the smoke detector according to the invention with expanded functionality. 
       
    
    
     DETAILED DESCRIPTION OF THE INVENTION 
       [0051]      FIGS. 1-2B  schematically illustrate the instant invention wherein  FIG. 1  illustrates an advantageous embodiment of the system  1  according to the invention for building automation and  FIGS. 2A and 2B  illustrate a perspective view and a sectional view of the smoke detector  23  according to the invention with expanded functionality. 
         [0052]    It is evident from  FIG. 1  that the system  1  according to the invention for building automation according to an advantageous embodiment includes a building  3  configured as a residence which includes for example a bedroom  5 , a kitchen  7 , a garage  9 , a living room  11  and a bathroom  12 . The bedroom  5  includes an electronically controllable alarm clock  13  and an electronically controllable light restriction device  15  configured as an adjustable blind. In the kitchen  7  there is a refrigerator  17 . The garage  9  includes an electronically controllable garage door  19  and the living room  11  includes a lamp  21 , a smoke detector unit  23  and a television set  25 . In all rooms  5 ,  7 ,  9 ,  12  furthermore presence detectors  27  for inhabitants (not illustrated) are arranged which are based for example on the iBeacon® technology by Apple Inc. Furthermore a telephone an Internet system, for example a Fritz® box  29  is provided and all of the building elements  13 ,  15 ,  17 ,  19 ,  21 ,  23   25 ,  27 ,  29  are linked with each other, wherein the network is can be provided wired or wireless, for example by WLAN. The network can be thus centrally operated by a special server or can be operated in a decentralized manner wherein the smoke detector unit  23  includes a proprietary server as will be demonstrated infra. 
         [0053]    As an alternative to an electronically controllable alarm clock  13  also a system like SONOS® can be used which includes a series of wirelessly connected speakers which facilitates synchronous playback on all speakers or for example only on speakers which are arranged in rooms that are currently being used. 
         [0054]    In this system  1  it is possible that individual building elements  13 ,  15 ,  17 ,  19 ,  21 ,  23 ,  25 ,  27 ,  29  display information from other building elements  13 ,  15 ,  17 ,  19 ,  21 ,  23 ,  25 ,  27 ,  29  and/or that building elements  13 ,  15 ,  17 ,  19 ,  21 ,  23 ,  25 ,  27 ,  29  are controlled or regulated by parameters which are provided by other building elements  13 ,  15 ,  17 ,  19 ,  21 ,  23 ,  25 ,  27 ,  29 . 
         [0055]    For example opening the garage door  19  by remote control from outside the house  3  can be used as a parameter to turn on the light  21 . Or a malfunction of the garage door  19  which does not close is directly signaled on the television set  25  when the presence detector  27  determines that the inhabitant is in the living room  11 . Or the non-function is indicated by a flashing or a color change of the lamp  21 , wherein the inhabitant detects this from the type of this display or is encouraged by the signaling to inquire about the reason for the signaling on a computer device, e.g. a telephone or a tablet computer. 
         [0056]    In  FIG. 2A and 2B  the smoke detector  23  unit illustrated in  FIG. 1  is illustrated in more detail. It is evident that a modular configuration is provided wherein the smoke detector unit  23  includes a conventional smoke detector  31  which includes a communication interface  33 . An adapter  35  is connected with this communication interface  33  through a communication cable  34  with a corresponding communication interface  36  wherein the adapter includes a device driver for the smoke detector  31  so that the smoke detector  31  can be integrated into the network of the system  1 . For this purpose the adapter  35  includes suitable communication devices, for example a WLAN connection (not illustrated). The adapter  35  is furthermore connected with a control and/or processing device  37  which is configured as mini server. Thus, the adapter  35  and the mini server  37  are configured as one single module. The smoke detector unit is arranged at a room ceiling  32 .  FIG. 2B  illustrates a sectional view from the side of the ceiling. It is evident that the typically provided attachment  38  of the smoke detector  31  is used for attaching the smoke detector  31  at the adapter  35 . The adapter  35  itself is typically (not illustrated) screwed together or glued together with the ceiling  32 . 
         [0057]    Two functional units  39 ,  41  are arranged about the adapter  35  and the mini serve  37  wherein the two functional units are mechanically connected with each other and are provided with a data connection to the adapter  35 . The functional units  39 ,  41  are plugged in around the adapter  35  and plugged into each other as evident in particular from FIG,  2 B. For this purpose corresponding plug connectors  143 ,  145  are provided which provide communications to the adapter  35  as well as a voltage supply for the functional units  39 ,  41  Thus, the adapter  35  is also an adapter for the smoke detector  31  and also an adapter for the function units  39 ,  41  through the plug connections  143 ,  145 . 
         [0058]    At one functional unit  39  illuminants  137  and a module for receiving audio and video signals  149  are arranged, whereas a motion detector  151  and a temperature sensor  153  are arranged at the functional unit  41 . The illuminants  147  are provided as low load LEDs which are not oriented directly towards the smoke detector  31 . The temperature sensor  153  can be used to control air conditioning or heating (not illustrated) and the illuminants  147  can also be used for signaling like the lamp  21  and can be used additionally also for normal illumination of the room  11 . The functional units  39 ,  41  are also randomly combinable with each other with different functions e.g. individually useable and mechanically and data connectable with the adapter  35 . 
         [0059]    The mini server  37  does not only control the functional units  39 ,  41  but also reads out the parameters of the smoke detector  31  and of the functional units  39 ,  41 . 
         [0060]    With respect to the mechanically interconnected configuration of the two functional units  39 ,  41  it is evident from  FIGS. 2A and 2B  that each functional unit  39 ,  41  is configured S-shaped in an axial direction with a protruding portion  39   a ,  41   a  and a recessed portion  39   b ,  41   b , wherein the recess portions  39   b ,  41   b  of a functional unit  39 ,  41  are respectively enveloped by the protruding portion  41   a ,  39   a  of the other functional unit  39 ,  41 . 
         [0061]    It is furthermore evident from  FIG. 2B  that the functional units  39 ,  41  respectively include a plurality of functional elements, illuminant  147 , module for capturing audio and video signals  149 , motion detector  151 , temperature sensor  153  which are respectively arranged in an alternating manner in order to achieve optimum functional distribution. 
         [0062]    The adapter  35  furthermore includes an external voltage supply (not illustrated) which also feeds the mini server  37  so that no energy is drawn from the battery  155  of the smoke detector  31 . In this context a control is helpful where the smoke detector  31  is supplied with energy through the conductor  157  through the external power supply of the adapter  35  and power is only supplied from the actual battery  155  when network power fails. This substantially increases safety since the battery is loaded less. 
         [0063]    The conductor  157  for the energy supply and the communication cable  34  are run through a cable pass through  159 . 
         [0064]    It is evident that communications between the smoke detector  31  and the adapter  35  are provided through the communication interface  33  of the smoke detector  31 , the communication cable  34  and the communication interface  36  of the adapter  35 . Alternatively the communication cable  34  can also be omitted and the two communication interfaces  33 ,  36  are uniformly implemented as plug interfaces. However, the embodiment with the communication cable  34  is preferred since for each smoke detector type  31  which includes a proprietary communication interface  33  only one proprietary communication cable  34  has to be provided and the adapter  35  itself can remain unchanged. 
         [0065]    The mini server  37  is adapted to collect and process information from the connected household appliances  17 ,  21 ,  25 , the smoke detector  31  and the functional units  39 ,  41  and can forward this information to a second control and/or processing device (not illustrated) which is provided for example as an IPad®. Simultaneously the mini-server  37  is configured so that it is programmable through the second control and/or processing device. 
         [0066]    When nothing else is stated all features of the instant invention are randomly combinable with each other. Also the features described in the figure description are features of the invention and are randomly combinable with the other features unless stated differently. Thus, device features can also be used as method features and method features can also be used as device features.
