Umar,



            Frank ad= dressed just about everything =96 on the things he
deferred..



            The ener= gy saving lamps should be connected via relay outputs
rather than to dimmers . Effectively C-Bus controls two types of load =96 lamps (via dimmers) or any ON/OFF load via relay modules. For your table lamps you could wire them through the small 2A/3A sockets and have them
either switched via relay modules for ON/OFF or connected to a dimmer
channel =96 you shouldn=92t of course leave them wired to a 13A socket that= was
controlled from C-Bus. If low voltage lighting is to be controlled via
dimmers then the transformers must be compatible with C-Bus=92 leading edge=
dimmer operation.

            Two bank= s of consumer units are very typical =96 the type of
consumer unit isn=92t really an issue as the modules are just DIN mount =96=
however it needs to be large enough to hold all you need . Clipsal offer dome nice wide ones. Really you are not using so much a consumer unit as a<= BR> mounting box for the DIN modules =96 however depending on how you organise<= BR> your isolation / fusing / mcb=92s you might want it all in one box.

            As Frank= said the connection to the C-Bus is via RS232 or
Ethernet depending on which you buy. The module sits on C-Bus and as such doesn=92t have to be in the consumer box although it is a DIN mount unit = =96 you
could run C-Bus to your PC and then keep the module behind it if that was easier.

            CAT5 is = a communications cable primarily =96 I wouldn=92t switch
loads with it although I=92m not sure that is what you meant =96 any ON/OFF= load
can be controlled by C-Bus via the relay modules =96 these could be wired t= o
door strikes if that was what you wanted.

Hi Umar
            I will t= ry and answer some of the questions and im sure Rob or
Kevin should be able to help.........

> 1 Each light circuit goes back to consumer unit?

    Each light or group of lights go back to the consumer un= it.........

> 2 Cat5e goes from switch plate back to consumer unit?

Cat 5 loops between switches and must go back to the consumer unit  (t= o
dimmers etc) ...
all C_bus equipment must have the cat5  connected to it not just switc= hes
also dimmers relay modules , pir detectors etc either daisy chained or star=
config............

Pretty  much so ......

Yes you can but just reading the clipsal tech notes there is an issue (in aussie at least) were the cat5 would have to have the same rating as the other mains cable in the consumer unit hence the clipsal pink cat5 is heavy=
duty and mains rated................as i understand it

Not sure on this one ...some electronic ballasts are a problem maybe one fo= r

Cant see why not this is what i would do if i was doing a multilevel
house..Although here in aussie the loft would not be a good location due to=
heat in summer ....44 degrees C last week in the roof space around 50...
One issue here in aussie is that lighting circuits are now required to have=
rcd,s installed on them so its important to have all loads on a dimmer for<= BR> instance connected to the same rcd...........

> 4 In fact what type of consumer unit required?

    One for Kevin or Rob sorry


> 5 Can I control table lamps with C-BUS? If so how?

    Maybe use a C_bus relay module ???? Would mean outlets c= onnected to the
sockets would have to be wired back to the consumer unit......

> 6 The system is PC controlled, and if that is in node 0, how doees tha= t
> connect to the consumer unit?

What i have done Umar is brought the C_Bus comms out to a socket rj45 and jumpered with a patch lead to my patch panel..At the other end i have the C_bus interface plugged into a rj45 socket (carrying the comms) and a seria= l
lead to my computer............

> 7 Can the system integrate with other products eg alarms?

Yes i believe there is a ucm module which links it to Comfort .....Kevin an= d
Rob will verify.......At the moment im using aux inout modules to talk to m= y
Genesis Alarm panel...............

Yep its a 240v 50hz system ...have seen some  mention of 110v 60hz as = well
somewhere.............

Run cat5 between all switches

Send me a return air ticket and i,ll do it ;-)) Really its not that hard ........The wiring side is easy and now there are a few users there is
programming help available............

I wouldnt use cat5 for electric strikes ....again you could use C_Bus relay=
modules BUT the electric stikes ( latches) usually 12v dc should have their=
own 12v power supply and battery back up..............

I dont use C_Bus pirs but Pulnix ceiling mount and i will be using the aux<= BR> inputs to relay pir status ..mainly for late nite lighting of hallway loung= e
kitchen etc.........
