C-BUS Control and Management Systems

The C-Bus solution is a high quality, simple to design and install control system suitable for lighting and power control. C-Bus is recognized world wide as being one of the most flexible and reliable systems. It can be configured without a PC. The C-Bus system is ideal for commercial and residential control applications.
This building automation package offers a reliable solution, the system seamlessly integrates to provide security, door access, lift control, HVAC control, giving a complete integrated building control package.

Overview of the C-Bus Control System

C-Bus is a microprocessor control wiring system to control lighting and other electrical services.
Whether ON/OFF or variable type control, C-Bus is used to easily control virtually any type of electrical load.
Control information is downloaded and held in CBus units, rather than all information kept on a central processing unit. Whilst a computer is unnecessary for normal C-Bus operation, there are several software-based tools available to provide additional flexibility to building managers requiring this type of control.

The C-Bus Network
A Network Bus is the communications wiring for the system, consisting of an unshielded twisted pair (UTP) ‘Cat 5e’ cable. The Network Bus also provides the small amount of power needed to operate the circuitry within CBus units. The C-Bus Network operates at safe extra low voltage levels (36V DC).

Free Topology Structure
The C-Bus connections may be looped from unit to unit, or a branched at any point. This ‘free topology’ structure provides a flexible system layout. New units can be added anywhere without system re-configuration.

Distributed Intelligence
All Units on the Network each have their own built-in microprocessor, non-volatile memory and operating program, allowing them to operate independently with “distributed intelligence”. This provides reliable, high-speed communications and ensures that a malfunction in one unit will not affect the operation of any other Unit.

Simple Control
The size of a C-Bus Installation is practically unlimited. A large installation is usually divided into Networks of 100 C-Bus Units, with a total cable length of 1000m per Network. This allows a C-Bus system to be divided into manageable sections, simplifying design, limiting potential fault propagation and aiding in any troubleshooting.

Multiple Events
A C-Bus key Input switch maybe programmed so that the length of time the key is pressed determines what Command is issued - a short press could issue an on/off command and a long press can control a dimming command. Single input units may control a number of Output Devices, and multiple Input Units may also control a single Output Device.

Logic
Conditional (IF–THEN–ELSE) statements can be programmed into a C-Bus system, allowing events to be based upon the status of other devices, time of day and other situations.

Ultimate Control Flexibility

The C-Bus system can carryout control in a number of ways, including;

• Centralised controls, via a PC or a C-Bus Touch Screen.
• Any input device can be programmed as a master control point.
• C-Bus has an over-ride control hierarchy allowing control of areas, buildings and sites.
• C-Bus allows practically unlimited switching configurations.
• There is no need for a mains voltage connection between any units.
• Any input can control any load, regardless of which circuit or phase.

Why Use C-BUS?

• C-Bus is simple to document at project design stage. Design changes can be made without changes to the wiring
• C-Bus can control many types of load, digital and/or analogue.
• A single C-Bus cable connection can control an unlimited number of devices.
• Control functions can be added, removed, moved or reprogrammed at any time without any hard wiring.
• Extra Output or Input Units can be added at any time.
• C-Bus is simple to install and commission.
• Powerful, flexible and fully customisable Software-based control and monitoring tools.

Applications for C-bus

• Stadium lighting.
• Architectural dimming.
• Smart home controls.
• Hotel lobbies.
• Hotel room control.
• Demand scheduling.
• Power device switching.
• Scheduling of switching.
• Street light control.
• Tunnel lighting.
• Factory and warehouse lighting.
• Boardroom presentation system.
• Golf course lighting.

Stand Alone Control Systems

Enerbus lighting control system is a fully programmable system; designed to reduce energy consumption.
Enerbus can be easily integrated into a building of any size either new build or retrofit
Simply:

1. Establish system bus using compact bus controller
2. Install low voltage bus with inexpensive data or alarm cable
3. Plug in system devices
• Presence detectors for occupancy information
• Output controllers for load switching
• Interface units to introduce external devices to the system
4. Program device IDs and parameters via easy to use handset

The result is a fully functional lighting control system
