Lighting management is as simple as A B C-Bus

Simple to install with low cost wiring

In conventional wiring, the load current passes through the switch mechanism via bulky and expensive mains wiring and is run vertically up wall cavities. When two way switching is installed, multiple runs of mains cable are run from the switch mechanisms to the load circuit. In a large complex, particularly where multi point switching is required, this can lead to massive networks of costly wiring.

C-Bus replaces all these switch wires with one low cost Unshielded Twisted Pair (UTP) cable or "Telephone Wire", for the control and monitoring of applications. Operating at a safe extra low voltage of 36V d.c. This UTP cable may be run directly between different control points, such as Key Input Units and still provide the same degree of flexibility.

Due to the unique design of C-Bus, there is no need to run UTP cables from the control point to the load directly. The microprocessor based system responds to data on the C-Bus to control loads. As a result, control and monitoring points may be daisy chained together, with the same UTP cable. An added benefit of using the safe extra low voltage is that units may be added to the C-Bus side without powering the system down.

Of course, C-Bus doesn't eliminate mains wiring completely. It is still used between the load control unit, such as a Four Channel Relay Unit, and the load. However, with careful planning, the amount of costly runs of mains cable are minimised and the amount of inexpensive unshielded twisted pair cable is maximised.
