The Roombox concept presented in this guide is a new-generation of electrical distribution installation promoting:

> Optimum energy efficiency for powered devices, by using them only as and when they are required;

> Flexible low-cost workspace;

> Comfort and productivity of the occupants through the use of "intelligent" control and monitoring methods.

Building projects that are better controlled over time and less expensive than conventional projects, offering an excellent level of comfort and improving the energy balance, are the ideal configuration building promoters, investors and specifiers are now seeking.

Throughout the logical approach to the electrical installation design phases, you can discover the principle of the concept and its many advantages:

In addition, Schneider Electric's Roombox concept uses innovative technology to protect goods and people against electrical faults: overloads, short circuits and earth leakage monitoring.

> Manageable packages electrical distribution by electrical contract on providing best value.

> Energy provided via a "power bus", reducing cable lengths and installation time

> More flexibility protection, distribution, monitoring, and control, as close as possible to the loads, and users.

> Space saving, by reducing the panel boards, and cable tray sizes.

Energy efficiency regulations

This standard specifies a method of calculating building energy performance. It assigns performance indicators to the automated functions, which include heating, cooling, ventilation, lighting, venetian and roller blinds.

Heating, cooling and ventilation control: although the Roombox does not deal directly with these functions, it nevertheless makes it possible to access high indicators by using the appropriate controllers.

Thermal regulations RT 2010 – for application in 2012

Each new thermal regulation reinforces the need for more accurate monitoring, from general metering to metering by function and by lot (storey, occupant, etc.) for buildings > 400 m².

They involve the heating, cooling, ventilation, and lighting functions.

BREEAM (BRE Environmental & Sustainability Standard) Certification

This originally British certification is the oldest and most commonly used throughout the world. It was established by the BRE - the Research, Testing, Consultancy and Training organisation - for use in the building sector.

After an assessment has been completed, it assigns a grade based on the quality of the design and a building's ability to be used in accordance with the environmental criteria affecting the health and comfort of its users.

LEED Certification (Leadership in Energy and Environmental Design)

LEED certification is the BREEAM's rival. It is a North-American standardisation system for high environmental quality buildings, which was developed by the US Green Building Council in 1998.

The assessment criteria include: energy efficiency, water consumption efficiency, heating system efficiency, the use of locally sourced materials and the reuse of any surplus materials.

According to its performance point evaluation, a building can qualify for one of four levels of certification: "certified-silver", "gold" or "platinum".

Schneider Electric Services and Solutions have a 50% direct impact on the LEED evaluation, which is sufficient to obtain Silver Certification.

Overview of the Roombox conceptContribution to conformance with energy regulations

Roombox and EN 15232European standard for the classification of automation solutions in terms of improving the Energy Efficiency of Buildings. This standard specifically recommends the use of the BMS and multi-application controls (scenarios).

These easy-to-configure controls are available in the Roombox.

Roombox and the European Energy Performance Building Directive (EPBD), the purpose of European Directive n° 2010/31/CE dated 19/05/2010.Is to promote the improvement of building energy performance in the European Community, by taking account of the outdoor climate conditions, particular local characteristics and the requirements in terms of the indoor climate and the cost/efficiency ratio. In particular, the directive requires the installation of a consumption measurement system.

The Roombox incorporates 3 energy meters measuring: the total electrical energy consumption of the Roombox and its loads; the total electrical energy consumption of the lighting loads.

Roombox and RT2010 (under development) It specifies a minimum performance level for building solutions and thermal systems. The trend is towards more accurate consumption monitoring, maximum permitted consumption, real-time analyses, etc.

The Roombox incorporates 3 energy meters measuring: the total electrical energy consumption of the Roombox and its loads; the total electrical energy consumption of the lighting loads.

Roombox and Building environmental and energy certification Apart from conforming to the current regulations, adopting a Roombox architecture makes it easier to obtain certification.

Protection and control are decentralised to reduce the use of copper (cables),

Automated control systems meet the energy management requirements,

The energy meters are integrated into each Roombox (several Roomboxes can represent a lot) making RT 2010 easier to apply and more economically advantageous.

The Roombox concept provides installation design solutions in conformance with present and fore secable future energy guidelines:

Zone D

The Roombox

FunctionsA Roombox is an all-in-one protection, metering and control device with a power supply input and 12 feeders for the equipment.

Front panel

The function of a feeder is determined at the factory and can be as follows:

Protected power supply, measurement of air-conditioning cassettes;

Protected power supply, motorised valve measurement and control;

Protected power supply, On/Off lighting measurement and control;

Protected power supply, lighting measurement and control, Dali ballast dimmer;

Protected power supply and Motorised venetian or roller blind control (230 V).

Each feeder has an input for a wired pushbutton or a wired window contact.

The Roombox has 4 inputs for the "Roombox" specific presence and light level sensors.

As an alternative to wired pushbuttons, the Roombox has a "remote-controlled radio receiver" function designed to receive orders from Zigbee wireless pushbuttons. Moreover, pressing the pushbutton generates the electricity necessary for transmission and no battery is required.

The Roombox provides its energy meter values: total energy consumed on its 16 A supply, total energy supplied to the lighting circuits, total energy supplied to the heating/air-conditioning circuits.

The Roombox can communicate with a Building Management System (BMS) via a LON or KNX network, depending on its version.

Roombox electrical distribution The 12 Roombox feeders are divided into 3 or 4 groups - or zones - each of which can control a complete or incomplete set of air-conditioning + lighting devices + motorised blinds.

The zone is usually assigned to a building module, i.e. the equivalent of an area of around 13 m².

The example below shows a space with four zones, A, B, C, D controlled by a Roombox:

zones B and D are assigned to separate offices;

zones A+C are combined functionally and assigned to a large collective office.

Operation in a separate zone:

One lighting circuit: controlled by one local pushbutton or presence + light detector or by one pushbutton + detector for switching off only. Two lighting circuits: controlled by one

pushbutton or by one pushbutton per circuit, or by one pushbutton + detector for switching off only.

Zone B

Zone D

Operation in zones combined by configuration:

Lighting: all circuits of the same type (general-purpose, corridor, window) operating as a single circuit, with their respective buttons then generating joint orders.

Roller blinds: all the pushbuttons generate joint orders. HVAC: the window contacts and movement

detectors generate joint orders.

Advantages of the Roombox solution throughout the project

Efficient designUltra selective output electrical protection due to static breaking technology

Terminal electronic breaking resulting from Schneider Electric's research complements upstream circuit breaker breaking capability.

Individual protection: each of the 12 Roombox feeders is protected by a static breaking unit.

Tripping: tripping can be caused by an overload, a short circuit or by detection of a leakage current of more than 10 mA.

Discrimination: there is total discrimination between all forms of individual protection and any upstream protection device ≥16 A , thus ensuring optimum continuity of service.

Short-circuit current breaking ("Ultra Limitation"): the response time before the actual breaking is one hundred times less than that of an electromechanical circuit breaker, i.e. 20 ms. Consequently, up to an Isc of 10 kA, the short-circuit current never reaches values higher than 140 A.

Remote reset: As opposed to electromechanical circuit breakers that require additional accessories for remote resetting, terminal electronic breaking offers various possibilities as standard, according to its parameter settings: room-mounting: resetting via the equipment control pushbutton, by the front panel "CLEAR" buttons, or via the building management system.

Resetting is only possible if the fault has disappeared.

Universality of protection and control through "zero current" electronic switching'

Switching the feeder ON at zero voltage and OFF at zero current allows any type of load, whether it be a resistive, inductive or capacitive impedance load, to be interrupted for protection and control.

This is specifically useful for lighting feeders, whatever the type of ballast.

This switching mode removes operating interference and extends the life of the equipment powered. Mechanical and electrical endurance are unlimited: no wear, etc.

Silent operation.

Economical designFewer power cables

A single "power bus" cable from a sub-distribution board supplies several Roomboxes, the number of which depends on the cross-section of the cable used.Example: 6 Roomboxes tapping off a 3P+N / 2.5 mm² cable.

Shorter control cables

The pushbutton cables converge on the Roombox with which they are associated, which is generally the nearest one. In addition, the inter-Roombox KNX or LON communication bus can be used to combine certain lighting sensors and pushbuttons.

Wireless and batteryless radio buttons ensure more flexible and faster installation.

Energy meters incorporated in the Roombox

More and more regulations require electrical load consumption to be monitored by type: lighting, ventilation. This differentiated metering is integrated into each Roombox.

The saving with respect to modular meters is obvious, as is the amount of space saved.

The meter values are regularly notified to the Building Management System via the communication bus.

They can therefore be monitored by groups of circuits with the same function, by geographical zone (storey, building, etc.).


11

Easier organisationMore logical, better defined electrical lot

As the lighting and roller blinds are controlled by the Roombox, their deployment is entirely the responsibility of the electrician.

During the learning phase, the Roombox recognises the pushbuttons and/or sensors and automatically assigns them to the lighting feeders and to the roller blinds.

Therefore, even before the building management system is implemented, the electrician can check each electrical control function in local mode and modify it if required.

The next phase, which consists of fine-tuning the BMS, will be more "fluid", since all circuits will have been checked.

Standard easy-to-procure connectors

The pushbuttons and loads are connected to the Roombox using standard polarised connectors (Wieland).

The use of preconnectorised cables shortens cabling times, prevents cabling errors and improves the safety of the power supply.

Easier installationSmaller switchboard footprint

The switchboards on each floor or in each zone only include protection for socket-outlet circuits and a limited number of 3P+N "buses" supplying "clusters" of Roomboxes.

The latter include the protection of terminal load cables (lighting, HVAC terminals, roller blind motors, depending on the version).

Frees up wall space

The Roomboxes should preferably be installed in a suspended ceiling.

Conventional electrical distribution architecture

Principle Main General Distribution Board

The MGDB receives the power supply for the building and controls the various sources.

It supplies the high-power equipment in the building, the feeders to the sub-distribution boards and some local loads and electrical network measurement and control devices.

Sub-distribution boards

The sub-distribution boards are installed throughout different buildings or different zones of a building and distribute energy to the safety, control and monitoring equipment and to each local load via dedicated feeders: lighting, connectors, HVAC terminals, etc.

Upgradeability

A large number of lines now converge at the sub-distribution boards. They generally follow the service ducts through the suspended ceilings and/or false floors of the buildings.

Changing the location of the loads with this conventional architecture which is appropriate for "fixed" buildings (hotels, educational establishments, hospitals, etc.) is very tricky: unsuitable cables have to be replaced, cables removed from controls, reassigned, etc.

The cost is generally high and the work takes a long time to complete. Solutions based on busbar trunking systems help to improve the flexibility of the working areas.

Roombox electrical distribution architecture

Principle Main General Distribution BoardThe upstream distribution remains standard, a MGDB supplies the sub-distribution boards.

Sub-distribution boards They supply: the circuits, the safety and control and monitoring equipment and the loads

situated in zones whose use is not likely to change: passage areas, service rooms, toilet facilities; the column circuits via the fast connectivity busbar, or trunkings making the

high and low current connectors available. This infrastructure is generally only finalised when the occupier's installation requirements are known, i.e. when the building is almost completed. The luminaires, air-conditioning cassettes and any motorised blinds will already be in place; the "busbar" feeders of the Roombox serving the zones where flexibility is

required: in general, open space (open plan) areas, office zones.

Roombox Preferably located in the suspended ceilings of corridors or open spaces, the Roomboxes can be regarded as mini protection and local control switchboards. Each Roombox protects and controls 12 circuits: lighting, HVAC cassettes, motorised blinds.

Although the air-conditioning terminals, luminaires and motorised blinds remain in place when dividing walls are moved, their electrical control generally changes: new control regulations, new pushbutton arrangements. The power cables and pushbutton cables are fitted with plug-in connectors that allow changes to be made quickly and easily, hence limiting any new electrical design to a simple layout change request. Wireless and batteryless pushbuttons also provide greater flexibility.

Example of a KNX configuration

Roombox communication network architectures

Information exchange The Roombox provides status information on each loads that it supplies and control. These information can be used in turn for monitoring purpose and control process. They can also be shared with other devices on the communication network for two way control purpose, central command, time management, display and analysis.

KNX architectureThe KNX architecture is highly appropriate for small and medium-sized buildings, where extremely decentralised control, mainly focused on electrical applications, is required. Its design is easily accessible to "Automation" or "Electrical" design offices.

The Roomboxes are directly interconnected in a "daisy chain" configuration or in parallel with a KNX bus. They are in fact similar to devices installed on a network and communicate with sensors, actuators and man/machine interfaces from the KNX product family. Schneider Electric provides a large range of KNX components, the ETS programming software and Technical support.

The main shared KNX functions

The ETS software is used to set the function parameters.

Time programming: using the 4-channel annual programmable clock (ref. MTN677029 or MTN 677129). This clock can for example control the lighting feeders of several Roombox by switching them on or off.

General controls: using multi-function pushbuttons (ref. MTN 623xyz and MTN 628xyz). The lighting on each floor is switched on and off from the entrance, with LED status indication. The blinds are all lowered collectively.

Temperature control: the multi-function pushbuttons (ref. MTN 623xyz and MTN 628xyz) incorporate a sensor and a thermostat that can send ON/OFF orders to a KNX actuator or an HVAC feeder on a Roombox connected to a two-way valve. The user has an LCD screen for setting the commands and displaying the temperature.

Equipment, meter and temperature status display and general controls: the 10" touch screen (ref. MTN 683090) provides the operator with simple, easily understandable communication (example: a photo associated with a particular event may appear). The touch screen is installed on the wall, at the reception or security desk. The operator can easily control the status of the lighting, the blinds, the outdoor and indoor temperature, turn everything off and close all the blinds with one touch of a button. He can check the lighting and air-conditioning energy consumption for each zone or overall.

Example of a LON configuration

LON architectureThe LON architecture is highly suitable for medium-sized and large buildings where management via a single monitoring system and interactivity between various systems: fire safety, access control, HVAC, electrical distribution, etc. is required. It is designed and configured by specialised design offices, generally in close association with the "Heat" and "Utilities" lots.

The LON connection is generally used to allow the supervision PCs to monitor the electrical distribution and for centralised control, control by occupancy times and to "transmit" the metering values, etc.

The Roombox are directly interconnected in a "daisy chain" configuration or in parallel with the LON bus.

Schneider Electric has designed a range of "VISTA" BMS systems based on "Xenta" controllers.

Touch screenXenta PLC – Web page server

Xenta input / output module

Shared LON functionsThese functions are similar to the KNX architecture functions.

Bus Lon

Stand-alone architectureIn this case, each Roombox operates independently, without a bus communication link with the others or with a central control system, after having been configured individually.

Note: the use of addressable radio pushbuttons allows several Roombox in close proximity to react to common manual orders: general switching ON/OFF in an open space (open plan area), for example.

ON/OFF lighting

Roombox functions

> Local automatic controlA Roombox "presence and light" sensor can be associated with the lighting in one or more zones.

Depending on the Roombox parameter settings, the lighting can simply come on after a presence is detected and remain on for an adjustable time or it can be switched on when a light threshold is detected or even when a presence and light threshold are detected.

> Mixed local controlThe pushbutton is used to switch the lighting on and off.

The "presence and light" detector: inhibits or switches off the lighting when the

brightness exceeds a predetermined threshold. switches off the lighting when no presence has been

detected for fifteen minutes.

ou

> Local manual control Pressing the local pushbutton controls the associated output as follows: immediate ON/OFF control or time-delay control (timer function)

A wired or batteryless radio button can also be used.

Local control authorisation/inhibition: they can be provided by a light sensor installed locally or on another Roombox or by a time program in a remote controller.

DALI dimmer lighting The Roombox contains "DALI Lighting" feeders that allow fluorescent lamps fitted with DALI ballasts to be powered and dimmed. Each connector has 230 V supply terminals and DALI communication.

The DALI feeder operates in broadcast mode: the command sent to the DALI bus is executed in the same way by all the ballasts. The ballast diagnosis return is, however, individual. The automatic addressing system makes it much easier to implement.

> ScenarioA scenario is the automatic combination of simultaneous actions on several devices in the same room. Example: in a meeting room, pressing a "projection" button switches off two lighting circuits and lowers the blinds. Another press cancels the action

A scenario can also be started up by a presence sensor in an office. Example: the occupant's arrival is detected and switches on the lighting (if it is dark) and the air-conditioning; after the occupant has been absent for fifteen minutes, the sensor will switch the lighting off and set the air-conditioning to "unoccupied" mode.

The Roombox incorporates scenarios that can be predefined and selected by the electrician, thus releasing the BMS from having to perform these tasks.

> Regulation equipement power supply / control (cont.)Valve supply / control (the HVAC system and the Roombox share the same bus)

The Roombox behaves as a KNX or LON output interface by executing the orders received from the zone controller via the common bus.

It opens/closes the valve according to the control requirements.

Energy management can be optimised by wiring a window contact to the input associated with the HVAC feeder. The status of the window is sent via the network to the zone controller concerned that can then trip the "Stop" mode (cut off the valve supply) if the window is open.

> Roller blinds (230 V motors)

> Venetian blinds (230 V motors)

A zone controller can be implemented on the BMS bus to coordinate the control of the lighting, air-conditioning and light-exclusion motors according to a general schedule, a central manual control, etc.

Besides the up/down functions, the direction of the slats can be accessed locally via a pushbutton and also via a communicating automated device that will adjust it according to the sunlight and/or the occupancy schedule.

The up/down action is controlled by a "long" (>600ms) pulse on the corresponding button.

Shutter control

Zone controller

Local control PB


Locally, the user has an up/down button to adjust the position of the blind, as required.

The Roombox provides the continuous neutral and applies the phase to the up or down wire of the motor according to the order sent. Consequently, the motor stops remain effective.

The order is maintained by the Roombox during a customisable time delay (depending on the window height and speed of the motor).

An intermediate stop is obtained by a "short" (<600ms) pulse on the opposite button. Slat angle change (rotation) is achieved through a serie of short pulses up or down.

Roombox buttons and sensors

Roombox range

Wireless, batteryless pushbuttonsAs an alternative to the wired pushbuttons, wireless, batteryless pushbuttons bring exceptional upgradeability to the Roombox concept the buttons being battery less completely release the operator from the constraints of maintenance.

These buttons are used to control the lighting and motorised blinds.

They communicate by radio with the Roombox to which they are assigned. The Zigbee communication standard used provides highly reliability for a moderate cost in local remote-control applications.

A micro-generator powered by the energy used to press the button makes it possible to dispense with the use of battery.

Transmission power < 1 mWRange In free field appromatively 100 m

Roombox implementation and architecture"Budget envelope" approach

> The number of Roombox, i.e. the prospective budget envelope, should quickly be assessed. The method is approximate, based mainly on a breakdown of the building modules.

Building module concept One floor of a building consists of the horizontal juxtaposition of building modules of identical dimensions, generally two windows wide, i.e.

For example: in France: usually 2 x 1.35 m; in the Netherlands: 2 x 1.60 m.

A module is fitted with the following standard equipment:

one or two motorised or manual blinds (they generally have combined controls);

one or more luminaires (with combined manual control; the row on the window side can be fitted with an inhibiting automated control);

an HVAC terminal;

The number of devices per module depends on the quality specified and the modularity required for any half-module assembly.

Precautions to be taken when defining packagesThe Roombox equipment will be integrated logically in the "Strong current – Low current" lot.

Caution! > Impact on the HVAC equipment (HVAC): the Roombox supply the controllers, the 230 V two-way valves, the HVAC terminals (cassettes, fan coil units, etc.). Those responsible for the HVAC equipment must therefore be informed that the total power of the Controller + Fan + possibly a backup resistor is limited to 600 VA (2.6 A).

> Impact on the various installations/woodwork is as follows: the Roombox supply 230 V and power the automated motor control.

Two examples of modules:

> The type A module is the most common.

> The type B module can be split into half-modules.

The corridors and other specially designated rooms are designed without reference to the module, as their equipment will be specifically arranged to suit each location.

Other types of modules are possible.

Roombox installationPrinciple

1- Installing the Roombox distribution structure

The optimum type(s) of Roombox must be determined and the feeders routed to the equipment in one or more modules.

The optimum arrangement is achieved when: minimum cable lengths are used; the Roombox cover one or more complete rooms,

as the operating scenarios can then be configured for these rooms.

2- Determining the building module equipmentIdentify the basic building module on the drawing.

Count the type and number of Roombox feeders it will require.

Motorised blinds: they can be wired to a single feeder and will operate simultaneously.

HVAC terminal: the power available on each feeder was limited to 600 VA (2.6 A). Good coordination with those responsible for the HVAC lot is required to ensure that the total power of the Controller + Fan + possibly a backup resistor is less than this value. The trend is for the major manufacturers to provide low power consumption terminals.

Luminaries: they are generally powered by two separate feeders so that only the luminaire on the window side is controlled by daylight.

Three to six feeders may be required for each building module, depending on the degree of flexibility and comfort required.

3- Optimising the roomsA room consists of building modules and possibly half-modules.

The optimum arrangement may be achieved by envisaging the connection of identical devices on several modules in the room in parallel on the same feeder. This solution will only be appropriate if there is no plan to divide the room up at a later date.

Otherwise, this room must be dealt with module by module. Combine the equipment from any half-module used with the appropriate adjacent module.

4- Optimising open space or an entire storey

A Roombox can cover several offices. Supplying offices on both sides of a corridor limits the length of the cables and makes it easier to carry out work on the Roombox which will be fitted in the centre of the suspended ceiling in the corridor.

It will be sensible to have a few spare feeders so that modifications can be made at a later date.

5-Corridors and service roomsThere is generally no intention to change the lighting in these zones. The luminaires in one zone should therefore be grouped together over a minimum number of Roombox outputs not exceeding the maximum available power (600 VA).

29

Offices on both sides of a corridor are supplied by the same Roombox.

The remaining available Roombox lighting outputs were assigned to passage areas in an attempt to optimise resources.

The Roombox chosen is:

A: ref. ORBL8L0S4HW

: 8 ON/OFF lighting outputs

: 4 HVAC outputs

A certain switchboard zone corresponds to each room.

The corridor luminaires are powered via a free channel in zones C and D.

Bus cables and tap-off unit protection regulations

Protection against overvoltages caused by lightning strikes Degree of Roombox protection: OVC3 (4 kV).

Bus cable protection against overloads and short circuits depends on the cable cross-section.

Protection against earth leakage currents is achieved: by 300 mA or 30 mA Vigi modules.

The protection used for the bus cable will also protect the tap-off unit with the same core diameter / cross section. For economic optimisation purposes, a tap-off cable with a smaller cross-section than that of the main cable may be used. This changes the risk characteristics and logically, appropriate protection is required at the tap-off connection.

This protection is not mandatory when its length does not exceed 3 metres according to IEC 60364-4-43, sub-clause 434.2.

The 16 A incoming circuit breaker incorporated in the Roombox also protects the tap off cable against overload, which combined with the 3M rule makes safe and compliant.

Power supply circuit via a three-phase bus cable

Practical example of Roombox power analysis

Roombox selected: Ref. ORBL8L0S4HW (8 lighting feeders + 4 HVAC terminals) to supply four 12 m² offices.

As in this example, the Roombox inrush current will frequently be in the region of 5 A (T5 lighting + 2-tube or 4-tube fan coil).

Under such conditions, each phase of a 5 x 2.5 mm² bus cable can supply up to three Roombox, i.e. 9 per bus cable: > i.e. 36 x 12 m² offices> as a summary calculation, select one 5 x 2.5 mm² cable for 450 to 500 m².

> Schneider Electric's solution: Canalis KDP busbar trunking system.

> Another solution: Wieland – Gesis flat cable and accessories

Canalis KDP is a busbar trunking system that uses a flat cable with factory-installed tap-off units to ensure the quality of the connection:

either at 1.20 m or 2.40 m intervals suitable for 0.60 m wide suspended ceiling tiles;

or at 1.35 m or 2.70 m intervals suitable for 1.35 m module facades.

> It is available in 3 x 2.5 mm² and 5 x 2.5 mm² versions.

A rack-out connector for 1.5 mm² cable allowing the supply phase to be selected is used to connect the switchboards to the main cable. http://www.e-catalogue.schneider-electric.fr/navdoc/catalog/ca/index.htm

The communication bus (not shown) is separate from the busbar.

Connectors on the flat cable are available to the installer, as required. The phase is selected by piercing the insulating material. Some cables also incorporate a data bus.

TCP / IP protocol This universal protocol is available on the RJ45 connector on the front of the Roombox. It is used to upgrade its microprogram (Operating System) by connecting it to a PC. The connection requires a CAT5e RJ45 cable ("network cable").

DALI lighting management system ports (depending on the version)

DALI protocol: in conformance with IEC 62 386

This protocol is available on two of the five DALI Lighting output connector terminals. It allows lighting commands and ON/OFF orders to be sent via a two-wire bus to luminaires fitted with DALI ballasts. Each "DALI lighting" power output of the Roombox supplies power to a ballast or group of ballasts that reacts collectively to each order issued ("broadcast" mode) via the Roombox DALI output.

Maximum length of each DALI bus: 25 m.

Energy-saving: the 230 V ballast power supply can be desable when the DALI control is set to 0%.

Maximum: 6 ballasts per line.

The input circuits are designed to receive orders from lighting pushbuttons and venetian or roller blind pushbuttons, as well as the status of a window contact.

A 3-pin connector accepts a single or double gang pushbuttons; in the case of a double gang pushbuttons, one pin is common.

This 3 pin connector is also used for window contacts. By default, the type of contact used is normaly open.

The button and sensor contacts must ensure correct operation under the following conditions:

> Switching voltage: 24 Vcc

> Current: 6 mA

Window sensor: preferably NO type (open when idle). Opening the window closes the contact. The use of a NC type contact requires a Roombox parameter to be modified via the configuration tool.

Connection to the Roombox input terminal blocks:

Check with your pushbutton manufacturer the compatibility of his material with ELV switching more specifically if you're planning to use standard 230 V push buttons.

In fact, depending on their technology, the contacts may get dirty over time, with the result that their conductivity becomes increasingly random.

Schneider Electric guarantees that its pushbuttons meet these requirements.
