Connection branch terminal - The bus system connection or branch terminals are colloquially called just bus terminals. They are used to create connections between a device and the red or black wire of the KNX line. Further information and the specifications of the bus terminal are part of the KNX manual and as such are described in detail there. We at the eibabo technology store are experts in the field of smart home installation and therefore have a very extensive selection of items for building automation. Put together your personal package of modules, couplers, actuators, sensors, detectors or transmitters or contact us. Together we will then determine the right components for your project. Of course, there are other types of connection and branch terminals. Just browse through our catalogue.Catalogue content:In this eibabo® catalogue Installation bus systems > Connection-/branching terminal for bus system you will find items from the following product groups:Item overview:Branch terminalBus connection terminalBus coupler terminalBus systemBus system connection/branch terminalBus technologyBus terminalCable bridgesCable connectionClampClipConnecting-/branching terminalConnection clampConnection lineConnection terminalConnection-/branching terminal for bus systemConnection/branch terminalConnector clampEIBElectronicsLow current connectorOvervoltage protectionPlug-in terminalsSystem accessoriesTerminal blockTerminal block connectorWiring jumperfrom the following manufacturers:Manufacturer overview catalogue Connection branch terminal:ABBBusch JaegerGiraHagerIssendorffJungLingg & JankeMDTMertenMetzSiemensWAGO
Power supply - Find out here how to supply your KNX bus system with power. What power requirements do the individual KNX participants have? Which items do we recommend? This eibabo catalog contains power supplies and system devices for various automation systems, such as LCN, radio bus, KNX and many other systems.How do I determine the right KNX power supply for my installation?The most common power supplies in this catalog are for the KNX bus system. To determine the required power supply, you should first look at the structure of a KNX network. A distinction is made here between segments that are divided into a specific hierarchy. Imagine a tree whose trunk splits into branches. Twigs come off the branches. The branches represent the smallest 'unit' and are referred to as lines in the KNX network. Each line consists of the power supply, a KNX bus line and the participants. A main line would be the branch that connects multiple lines into an area. The area line represents the trunk that connects multiple areas. This structure makes sense for larger networks or if a division into several segments is recommended due to the structural conditions of a building.In addition to the power supply for the participants, the bus itself also requires a power supply of 24V nominal voltage. This is transmitted along with the data signals on the bus line. Depending on the manufacturer, the corresponding power supplies deliver 28V to 31V slightly more than the nominal voltage. This creates a buffer, for example for possible line losses. KNX bus participants still work stably up to 21V. The voltage difference is used to compensate for voltage drops in the bus line or at the contact resistances. A line can theoretically include up to 64 devices and provides a maximum current of 640mA at a voltage of 28V to 31V. This statement is based on the assumption that each KNX participant is allowed a maximum of 10mA from the bus voltage. The load capacity of the strongest power supply of 640mA continuous current must not be exceeded.Please plan in reserveWhen dimensioning your lines, allow at least 15% buffer for later extensions. A 640mA power supply therefore corresponds to around 54 devices.Smaller KNX power supplies are also available for fewer participants per line. If you know in advance that a line will never have more than a maximum of 32 subscribers (27 with buffer), you can choose a 320mA power supply. The same applies to a line with a maximum of 16 devices (14 with buffer). A 160mA power supply is sufficient here. In addition, there are larger 29V-30V power supplies with current limiters 640mA and KNX chokes separately. A KNX power supply always contains a KNX choke.The power requirement of a KNX participant is usually standardized. This should not normally exceed 200mW. 150mW for power supply of the microprocessor and 50mW for the bus terminal. There are many KNX devices that do not require this power reference. There are also KNX participants with higher requirements, for example KNX actuators, KNX room controllers or KNX displays. Please take this into account when sizing your lines. Pay attention to possible voltage drops, because the devices do not draw a certain current from the bus, but a certain power. If the maximum current is expected to be exceeded, you should integrate fewer than 64 participants in this line.How does the KNX power supply work?In the KNX power supply, the power supply always provides direct current (DC) at the output. The difference between the designation transformer and power supply is essentially that a classic transformer always outputs alternating current (AC) and also only works with alternating current at the input. Depending on the manufacturer, the power supplies generate a supply voltage of 28V to 31V. When the bus is idle, the supply voltage of the power pack is present. This state corresponds to a logical '1'. The logical '0' is generated by an alternating voltage. In order to send the '0', the sending KNX device reduces the voltage by around 5V for a short time. This results in an immediate compensating impulse, which comes from a choke integrated in the power pack. The KNX line is thus decoupled from the associated KNX power supply by the choke. This prevents short circuits in the data telegrams caused by the power pack. The voltage change is necessary so that the recipient can use the informationAre there KNX power supplies for more than 64 participants per line?In the eibabo® technology store you will find KNX power supplies up to 1280mA. However, it is not possible to set up a line with 128 participants. The power is distributed at two different outputs. There is thus the classic choked output with 640mA for the KNX bus as well as another unchoked output. Participants can be supplied with an auxiliary voltage via this output, for example a heatable rain sensor. Alternatively, you can use it to set up a second line. An additional choke is required for this.Image: Siemens 5WG11525-1AB22 KNX power supplyCan I monitor the utilization of a power supply?If you want to check whether a power supply is reaching its limits in use, we recommend a device with an integrated diagnostic function. This allows device temperature, output current, output voltage, bus traffic and other current measured values to be sent via KNX. This enables troubleshooting or general monitoring.What do I need a KNX emergency power supply for?Whether you need a KNX emergency power supply depends on how high you assess the risk of a power failure and its consequences for your system. The emergency power supply is used to buffer the bus voltage. An external battery is connected to the device. This provides a voltage of 12V DC and ensures the bus voltage for some time. The integrated charging electronics of the KNX emergency power supply recharges the battery or maintains the state of charge. You can record the operating states (mains voltage, error warning, battery operation) using a binary input, for example. As a rule, KNX emergency power supplies are mounted on the DIN rail. Both the KNX emergency power supplies and the required batteries are available here in the eibabo® shop at reasonable prices.What does PoE power supply mean?The abbreviation PoE stands for 'Power over Ethernet'. This allows you to transmit the electrical power required for the operation of the individual participants via the data lines of the network cable. You do not need a separate power cable. TIP:With a PoE power supply, the effort involved in cabling wired Ethernet networks is reduced. With this technology, the electrical voltage from the power supply is fed into the data cable. On the participant's side, this is diverted out again. To avoid interference, the participant should be PoE compatible. In this way, it can cleanly separate the incoming supply voltage from the data signal. If the end device is not PoE-compatible, the additional installation of a passive PoE splitter is necessary. The splitter takes the supply voltage from the data cable and feeds it via a separate line to the power input of the end device.Can I get classic 12V and 24V power supplies for conventional applications from eibabo®?Our classic power packs for the top-hat rail can be regulated depending on the model and are suitable for the power supply of external equipment. In addition, it is possible to use these for other equipment. Using a choke and a component for current limitation each, specific power supply units can also be used to supply one or more KNX lines. In addition to the installation technology, we offer you classic power supplies for universal use.What power supplies and manufacturers would you recommend?Basically, we recommend that you choose a device that suits your needs. Voltage supplies / power packs are standardized and are subject to legal requirements and regulations. If the technical parameters are completely identical, a price comparison between different manufacturers is of course worthwhile. In this catalog you will find KNX power supplies, KNX power supplies, KNX commissioning power supplies, KNX emergency power supplies, PoE power supplies, bus power supplies, IP power supplies PoE, battery modules for KNX power supplies, 12V power supplies and 24V power supplies for conventional applications.

Manual wall transmitter - Manufacturers of radio bus systems for home automation systems use different radio standards (EnOcean, Z-Wave, ZigBee, Bluetooth Smart, Bluetooth, WLAN). Leading manufacturers are Eaton Eltako and Thermokon. This catalog offers wireless handheld wall transmitters for different automation systems made by different manufacturers. Radio bus systems are an alternative to building automation systems such as KNX, LON or LCN. Radio bus systems are much cheaper and the range of applications and devices differs from manufacturer to manufacturer. Therefore, one should not use proprietary radio bus systems, but a radio bus system where devices of different manufacturers are compatible, such as with the KNX. However, in radio bus applications, the scope of options is always increasing in order to meet the smart home requirements. Radio bus systems can be connected to building automation systems, for example to KNX. Thus, mixed applications are possible, for example if installations with cables and wires are not possible (glass constructions, wood surfaces, open spaces). Compared to building automation systems, it is easier to put wireless home automation systems into operation and they are cheaper, but they are also less flexible when it comes to complex functionalities and future extensions. eibabo provides battery-free wireless wall transmitters, wireless remote controls, wireless handheld transmitters, handheld KNX radio transmitters, KNX radio wall transmitters, wireless outdoor transmitter module, wireless handheld multi transmitters , KNX RF transmitters, KNX wall transmitter modules, wireless wall transmitter inserts or wireless universal transmitter radio bus from leading radio bus manufacturers such as Berker, Busch Jaeger, Eaton, Elso, Eltako, eQ-3, Gira, Hager, JUNG, Peha, Schalk, Siemens and Thermokon.Catalogue content:In this eibabo® catalogue Installation bus systems > Hand-/wall sensor for bus system you will find items from the following product groups:Item overview:Bus system handheld/wall transmitterBus system wall transmitterBus technologyDouble asterEnd stripsHand-/wall sensor for bus systemInstallation switchManual transmitterMoellerfunkPosition buttonQuad buttonRadio button interfaceRadio remote controlRadio systemRadio transmitterRadio wall transmitter insertRemote controlSingle buttonSolar cellSurface-mounted buttonTransmitter insertTransmitter useTransponderWall transmitterWall transmitter completeWall transmitter insertWall-mounted transmitter completeWall-mounted transmitter insertfrom the following manufacturers:Manufacturer overview catalogue Manual wall transmitter:BerkerBusch JaegerEatonElsoeQ-3GiraHagerJungPehaSchalkSiemens
Bus bar - Busbars are electrical engineering components that are used as a special form of busbars within electrical systems to distribute currents to individual power lines. They mostly consist of highly conductive metals such as copper or aluminum alloys. They are available in the eibabo shop both as a single busbar and as a multiple busbar. In smaller switchgear, individual busbars are often used, which provide even more clarity there. On the other hand, multiple busbars are used in more complex systems, where they increase not only clarity but also the redundancy of the system. Their use is often possible even when only a small amount of space is available. Quadruple busbars, on the other hand, are special forms of multiple busbars that can be used in parallel to switch individual circuits, while other circuits have to be taken off the grid for maintenance work, for example.Catalogue content:In this eibabo® catalogue Low-voltage industrial components > Busbar you will find items from the following product groups:Item overview:Automatic trackBaseBase elementBulkhead profileBus barBusbarClamping railComb railConnection bracketCopper busbarCopper railsCopper tabsCover profileCu busbarCu flat barCu railEquipotential bondingFeed blockFlat railInstallation kitLadder railMeter access linePhase railRetaining tabShield clampSpare PartsSwitch disconnectorThreaded barTransducer tabsfrom the following manufacturers:Manufacturer overview catalogue Bus bar:ABBABNDEHNEatonEltakoEricoFinderGSABHagerHenselMersenRittalRockwellSchneider ElectricSiemensStriebel & JohnWAGOWöhner
Data rail - A data rail is required in a KNX bus system if the KNX devices to be installed in an electrical distribution (REG = DIN rail-mounted device) dispose of pressure contacts on their rear side. The data rail provides a connection between the KNX bus and the KNX device by means of the usual KNX bus terminal. The data rail is glued into the DIN rail (self-adhesive). Often, data rails with mounted data rail connector are offered, so no connector must be ordered separately. eibabo sells data rails in different lengths depending on the required space or horizontal pitches (HP) or space units (PLE). One space unit is standardized and equals 18mm, the width of a normal circuit breaker. The data rail consists of 4 horizontal conductor tracks. The assignment according to KNX standard, including the terminals at the data rail connector is from the top to bottom as follows: Yellow: + 24V, red: + KNX bus, black: - KNX bus, white: 0V. The outer conductor tracks / connector terminals (yellow and white) supply the KNX lines via a separate KNX choke. A data rail should not be shortened! To protect remaining blank spaces on a data rail, cover strips can be snapped on. KNX data rails have existed since the beginnings of the European Installation Bus (EIB) and are increasingly disappearing from the market, although the data rail is actually very practical and convenient. As far as the production is concerned, pressure contacts on the rear side are much more expensive and the reason, why almost all manufacturers have switched to direct bus connection contacts (bus terminals). The advantages of the data rail are the much better overview of the electrical distribution, reduced wiring costs (KNX bus) between KNX devices and the reduction of wiring errors (+/- reversed). However, it can be assumed that there will be fewer KNX devices with pressure contacts in the future. In this eibabo category you will find data rails, cover strips for data rails, data rails with connectors and data rails for deep and shallow top hat rails of the brands Berker, Hager and Siemens.Catalogue content:In this eibabo® catalogue Installation bus systems > Data rail for bus system you will find items from the following product groups:Item overview:Bus systemBus system data railConnecting bridgeData railData rail for bus systemEIB data railInstabus data railInstallation bus data railKNX data railRailfrom the following manufacturers:Manufacturer overview catalogue Data rail:EatonEltakoPepperl + FuchsSiemens
Room temperature controller - When building a new house or renovating, you have numerous interesting options for organizing the control of the room temperature. We will tell you how you can use various bus systems such as KNX, radio or LCN in addition to the conventional temperature setting. Automation not only increases living comfort, but also contributes to the value of your building. This enables you to make necessary adjustments or changes even when you are not at home. This eibabo® catalog provides room temperature controllers for all common applications.What are KNX room temperature controllers?KNX room temperature controllers are part of a building's heating system. These are used for individual room temperature control of interior rooms and have various measuring ranges. The respective devices can differ significantly in terms of application and the functions provided for operation and comfort. For example, the differences are whether static heating surfaces or underfloor heating are to be controlled or whether air conditioning and ventilation functions are to be provided.Do not confuseThermostats are also known as room temperature controllers. Installed on radiators, however, they measure the temperature at the heating and usually only differentiate between on and off.KNX room temperature controllers, on the other hand, continuously control between 0 and 100 percent and use a heating actuator to communicate with the heating actuators.How is the room temperature controlled using KNX?A KNX room temperature controller determines the control difference between the target temperature and the actual temperature. The calculated control difference is sent as a 1-byte command value telegram (a value between 0 and 100 percent) via the KNX bus to the corresponding channel of a heating actuator. This processes the signal and then controls the actuator.The following small example illustrates the rough functionality. The actual manufacturer specific control algorithm may be different:The room temperature controller determines a current temperature of 18 degrees Celsius (controlled variable). However, the desired room temperature should be 22 degrees Celsius. The 22 degrees Celsius then represents the setpoint for the controlled variable. The resulting difference between the actual value and the setpoint is the control deviation. The control difference is 4 degrees Celsius and is used to determine the control variable that is to be used to influence the room temperature. Assuming the manipulated variable is 25%. This value is transmitted as a 1-byte telegram (0-255 = 0-100%) from the room temperature controller to the heating actuator. In this case 63.75. For example, the actuator takes 2 minutes to fully open. The time required for the respective actuator to open or close can be found in the data sheet for the thermoelectric actuator. This information must have been previously stored in the parameters of the actuator using Engineering Tool Software (ETS). With a command value specification of 25%, the actuator would switch on the actuator for 30 seconds (this corresponds to 25% of 2 minutes) and switch it off for 90 seconds. The actuator then switches on again for 30 seconds and so on. If the room temperature controller calculates and transmits a different command value specification, the switching cycle for the actuator also changes.Image: Gira 210003 KNX continuous controllerWhat is the difference between KNX continuous controllers, KNX object controllers and KNX room temperature controllers?The selection of KNX temperature controllers is very large. eibabo® offers products from all leading manufacturers of control technology for HVAC (heating, air conditioning, ventilation) in smart home automation. These include ABB, Berker, Busch-Jaeger, Eaton, Elsner Elektronik, Eltako, EIBMARKT, Gira, Hager, Issendorf, Jung, Lingg & Janke, MDT, Merten, Siemens, Theben and Thermokon. Many of these manufacturers use different designations, such as KNX continuous controller, KNX object controller or KNX room temperature controller.KNX room temperature controllers continuously record temperature values and forward them to other system components as KNX signals that can be evaluated. This process takes place continuously. A KNX continuous controller is therefore the same as a KNX room temperature controller. The situation is different with a KNX object controller. Object controllers are room temperature controllers without direct adjustment options on the device for the setpoint temperature. Object controllers were developed for object use. In public objects, as a rule, direct adjustment by strangers should be prevented. The values are parameterised directly via the ETS (software). You can change these directly via KNX (KNX buttons, KNX operating panels, KNX visualisations) in the setpoints. KNX object controllers are often cheaper and suitable in private areas for corridors, basements or storage rooms.What do you have to consider when positioning a KNX room temperature controller?As a rule, the installation is carried out using a branch switch box with 4 screw bosses, one switch box deep. Alternatively, use an electronics box if a separate bus coupler is required. With our convenient search function, you can quickly find the right items here in the eibabo® technology store. TIP:There are multi-channel KNX room temperature controllers for installation in your electrical distribution. Here, the temperature is measured via separate KNX sensors, for example from KNX buttons or KNX motion detectors with an integrated temperature sensor. For optimal use of all functions and the best possible recording of the measurement data, please ensure that the installation height is 1.60 m from the top edge of the finished floor. In this way you ensure optimal control and user-friendly handling.How is a room temperature controller connected to the KNX bus?KNX room temperature controllers are equipped differently by the manufacturers. You can either buy the KNX room temperature controller including a bus coupler or you have to order the bus coupler separately. The required interface between the KNX bus and the KNX room temperature controller is called the bus coupler. You can tell whether your controller has a bus connection by the red and black bus terminal. The KNX controllers often offer included KNX binary inputs. These are used, for example, to integrate conventional buttons in the room to switch lights via KNX. These binary inputs usually correspond to the technical data of KNX push button interfaces and can therefore only be extended up to a maximum of 50cm.How important is the appearance of a KNX room temperature controller?There are controllers with or without a dial to adjust the temperature. Other models are operated via the display and menu controls. Everything is possible here. The controls should match your other switch range and reflect your modern, classic, simple or extravagant style of living. TIP:Don't just look at the exterior of a KNX room temperature controller, but also at its inner values. There are often considerable differences in the application developments (software) of the manufacturers. The possibilities that the respective software can offer you may be relevant to your project requirements. Think of:control behaviorInfluencing control processesOperating modes and external switching options or setpoint adjustment optionsstatus feedbacknumber of group addressesBehavior in the event of a bus voltage failureand much more What other properties should I consider before buying a KNX room temperature controller?In addition to the technical, optical and software properties mentioned, other factors can speak for or against a specific model.Do I need anti-theft or dismantling protection?What color or what material do I want for the control panel?Do the local conditions require wireless data transmission?Should it be regulated via a room controller?and some more What are room controllers with integrated KNX room temperature controller?An alternative to the KNX room temperature controllers presented here are the KNX room controllers, provided they have an integrated temperature controller. These are devices that you can use to centrally control lighting, temperature and blinds, for example. Such controllers can be used via individually assignable control panels for switching, dimming, regulating or controlling all required actuators and sensors. You can also get numerous high-quality KNX room controllers here in the shop at top conditions. Use our intelligent search for your research.  Catalogue content:In this eibabo® catalogue Installation bus systems > Room temperature controller for bus system you will find items from the following product groups:Item overview:Building system technologyBus technologyButton interfaceClock thermostatContinuous controllerControllersEnd stripsEnergy efficientHeating controlHeating technologyHome controlHumidityMoellerfunkMoisture meterMultifunction displayNetworkingObject controllerRadio systemRadio transmitterRemote room sensorRoom controllerRoom sensorRoom temperature controllerRoom thermostatTemperatureTemperature controllerThermostatWireless temperature sensorfrom the following manufacturers:Manufacturer overview catalogue Room temperature controller:ABBAlre-itBerkerBusch JaegerEatonEberleElsnerElsoEltakoGiraHagerJungMDTMertenSiemensTheben
Energy management - This catalogue offers articles used for energy measurement or energy optimization in various bus systems, for example for radio bus system applications or the KNX bus system. KNX energy meters can be used for utility cost billing or cost monitoring, for cost center billing, energy optimization, visualization or installation monitoring. These KNX meters do not only capture and display consumption values, they also display other functions. They can be used to identify high consumption devices, to switch off specific channels if thresholds are exceeded or just to display the daily energy costs, voltage, current and power data. KNX visualization can generate a variety of display formats depending on time or load profile, can store your energy provider?s current prices and display accrued costs and compare them. For billing purposes, the meter should absolutely be calibrated and have MID approval. MID means Measuring Instruments Directive. The MID is a EU directive covering measuring instruments. Even in case of bus failure, the meters should continue to collect and store data. All KNX meters can be ordered as calibrated or uncalibrated type and with / without MID certificate. In Germany, for example, electricity meters used commercially must be calibrated. Therefore, check whether the meter intended for commercial application can be used in your country. After expiration of the calibration period (8 years for electronic meters, 12 years for mechanical transducer meters with induction system or 16 years for mechanical meters with induction system), the meter has to be replaced or the calibration period extended. Carefully study the features and parameters of the meters provided by different manufacturers to find the most suitable meter. There are different types of KNX meters, for example, direct meters or transformer meters for very high currents. In single-family houses or apartment buildings KNX direct meters are generally used. These are usually available up to 100A. In this eibabo category you will find, for example, radio single-phase meters, KNX energy meters, interface modules, energy measurement sensors, KNX power modules, KNX sensors, KNX meter interfaces, wireless energy sensors, KNX peak load limiters, bus electricity meters of the brands ABB, Busch-Jäger , Eaton, Eltako, Gira, Hager, Lingg & Janke, Merten and Siemens for various automation systems.Catalogue content:In this eibabo® catalogue Installation bus systems > Energy management for bus system you will find items from the following product groups:Item overview:5-level maximum guardBus systemBus system energy managementConsumption meterDIN rail counterDirect/ConverterDirect/transformerEIBElectricity meterEnergy counterEnergy efficientEnergy management for bus systemEnergy measurementEnergy meterEnergy visualizationInput moduleMaximum demand monitor for distribution boardMaximum guardMaximum GuardianMaximum monitorMaximum monitoringMeter scannerMoellerfunkPeak load monitoringSwitching actuatorThree-phase meterTransducer measurementTransmitter modulefrom the following manufacturers:Manufacturer overview catalogue Energy management:ABBEatonEltakoGiraHagerJungKOSTAL SolarElectricLingg & JankeMertenSchneider Electric

Experience the advantages of the products we offer: simple and intuitive operation, proven technology, low prices for handset telephones and hands-free devices. Choose from high-quality and inexpensive in-house telephones and indoor telephones, audio indoor stations and audio indoor stations, door telephones and door intercom systems, bus hands-free telephones and bus telephones, hands-free stations, analogue in-house telephones and system telephones for intercom systems.This catalog of our shop offers audio in-house telephones and home stations. If you are interested in devices with video function, please select the 'Video intercoms' catalogue. There are also separate catalogs for the product groups 'intercom video systems' and 'door intercom sets', where you will definitely find what you are looking for.What are the possible uses of in-house telephones?Housephones and intercoms typically serve two distinct purposes within homes and other buildings. On the one hand, the devices are used to communicate with people at entrance doors, gates or passage locks. In some cases, access control is implemented in houses with several apartments or commercial units. On the other hand, in-house telephones are used as a means of communication among one another. This feature may not be as relevant in the age of ubiquitous smartphones. Nevertheless, it is used for improved communication and quick coordination between people in different rooms or on different floors.NoticeA simple in-house communication network works without an external exchange. No authorization or connection to a telephone provider is required to use these systems.If necessary, the connection to the landline network, mobile network or Internet is possible. It is then also possible to make contact from outside the network.Classic use casesYou probably know the classic use cases. House telephones are standard in hotels, retirement homes and hospitals. With a short (usually one or two-digit) number you can reach reception, an in-house service provider or the ward nurse. Of course, such a system also facilitates communication between employees. Especially in an emergency, various people can be informed and alerted within a very short time.But in-house telephones are also becoming more and more popular in the private sphere, connecting the kitchen, living room, children's room or garden shed with one another. In certain situations, house phones are a good alternative to mobile phones. Family members do not always carry their smartphones with them. Some examples are:Communication in rooms with poor mobile phone reception (basement, laundry room)Communicating with people in places without a cellphone (garage, sauna, pool)Communicating with younger children without cell phonesListening to other rooms (baby monitor function) Image: Siedle HTA 811-0 W in-house telephoneWhat functions do audio in-house telephones offer?In-house telephones signal the door call or an internal call. The devices are designed in such a way that the signal is received directly and played back as a ringtone/call tone. In-house telephones establish a speech connection with the connected intercom. Depending on the model and installation, the devices also differentiate between the floors, departments, contact persons or doors. Furthermore, you as the operator are able to open doors and switch on the light via the telephone. With many devices, the ringer volume can be conveniently adjusted on the device or switched off completely (muting). With some systems, a radio can be integrated into the master control unit, which broadcasts music to different parts of the house. TIP:Depending on the model, an in-house telephone can be installed surface-mounted, flush-mounted or on a DIN rail. If you do not want a fixed installation, we recommend a modern tabletop device. At eibabo® you will also find a large selection of devices for bus installation. This enables you to implement a variety of communication and control functions with your smart home in-house telephone system. These include, for example:automatic door openers and door monitorsMonitoring and control of garage or courtyard gatesSwitching and controlling lighting scenariosthe activation of camerasHandling internal calls and forwarding door calls to other extensions What advantages do wireless in-house telephones offer over wired models?A big difference is the way the in-house telephones are installed. There are wired and wireless audio intercoms. Permanently installed, wired audio systems are widespread. These require the laying of cables within the walls, between different rooms and floors of the house and at the doors. The installation of a wired system should be well thought out beforehand. Installation is best done while the solid walls and drywall are still open and accessible during a construction phase. Subsequent laying of the lines causes dirt and can cost a lot of time, work and money. The advantages and disadvantages are:the range can be determined individually by the length of the cablesModels with cordless handsets expand the radius of action even furtherClosed wired systems cannot easily be eavesdropped on from the outsideFlexible construction according to local conditions possiblewired systems have to be installed at great expenseChanges and extensions are difficult With a wireless system, you reduce the installation costs or you can install a system without complex construction work. On the other hand, the system must have the required range to also be able to integrate distant participants. Under unfavorable conditions, the use of range amplifiers is recommended. In the event that further participants are added, a system should be expandable. The advantages and disadvantages of wireless systems are:easy and inexpensive installationflexibly expandableEnvironmental conditions affect performance Can audio in-house telephones be expanded with a video function?The core functionality of a simple in-house telephone is basically pure audio communication. This is accompanied by some restrictions in terms of comfort. With this in mind, video intercoms are more popular. This also allows you to see who is at the door. Communication between the individual areas of a house with a video function is also more convenient. It is possible to add a video function to an already installed audio system, but this does not always make sense. Keep in mind that you may need to install additional wiring and purchase cameras and monitors. The technology must also be designed for the additional functions. As a rule, it is therefore easier to replace old devices with new devices with integrated video functions (and other functions). The existing installation can continue to be used.Video systems are available in both wired and wireless configurations. Video quality may vary. Some models transmit only black and white, others color. Some only offer low resolution and others transmit high resolution images. Depending on the model, an infrared-based night vision function is available. Depending on the equipment, the video transmission can be in one direction or in both directions.Can I integrate a simple in-house telephone into a smart home system?If you already have an intelligent system for internal house communication, you can usually expand it. However, it is not necessary to install a device with video or other functions at every point in the network. The opportunity for a brief audio consultation is often sufficient. Many manufacturers offer compatible telephones for their own systems, which can be seamlessly integrated into the system. As a specialist center for building automation, the eibabo® shop offers a large number of bus-capable in-house telephones from all well-known manufacturers. These include Busch Jaeger, Siedle, Grothe, Ritto, Merten, STR and Gira.  Catalogue content:In this eibabo® catalogue Communication technique > Indoor station door communication you will find items from the following product groups:Item overview:Base unitBus phoneButton setColor monitorCompact call stationDoor intercomDoor phoneHands-free deviceHome stationHouse phoneIndividualIndoor phoneIndoor stationIndoor unitIndustrial stationIntercomOffice intercomResidential stationScrew stripStandard phoneStationSystem devicesSystem phoneTelephone handsetTouch screenUniversal phoneVideo intercomVideo systemfrom the following manufacturers:Manufacturer overview catalogue In-house phone:Balcom ElectronicBusch JaegerComelit GroupElcomElsoGiraGrotheIndexaLegrand SEKOMertenRittoSiedleSTRTCS
