How does Daisy Chaining work?

[virdi]

Hi all,

 

So I was looking at the Scantronic I-ON panels and I read something about 'Daisy Chaining' or BUS Wiring - Where you can install the devices - from one to the other.

 

Can someone explain if this actually works? and how it is done? ...and how does it work?

 

....does this work for PIRs? or only Key Pads?

 

Thanks

BUS detection devices would only be compatible with certain compatible control units and there matching manufacturer.

Most modern equipment utilises some data BUS type wiring for the keypads and zone expanders, which I believe is the case for the iON.

Essentially each device has an address so they can be identified back at the control and they all communicate and get powered from the same line.

Often this is wired as a pair for power and pair for data.
