  1. Group...
    Can anyone provide an explanation, of cite applicable code, as to why it
    is not a good practice to install and mix different brands and/or models
    of 2-wire smoke detectors on the same fire zone (ademco vista panel,
    2-wire fire loop).
    TIA, Nick
     
  2. Roland...
    Right you are... but what about mixing different brands/models of cross
    listed smokes on the same loop?

    Because it creates a visual flow, using different smokes interrupts that
    flow

    Maybe different tolerances will interupt the electron flux?..like "crossing
    the streams".

    Dunno, but I don't mix them anyway.


    |I give up. I think if they are listed to work with the panel then they
    | should work with each other. I am not a EE so what I say isn't worth much.
    I
    | guees you'd have to put the question in writing to the manufacturers to
    get
    | their take.

  5. The Reason they do not want different smokes mixed and matched is because of
    potential differences in voltage and amperage draw and possiblity smokes
    will false or not work at all because one on line is drawing to much current
    etc.
    I have seen this happen with some panels they have very little tolerance for
    different sokes et I have seen other systems and panels operate with no
    difficulty accepting what ever you put on them.

    that's what I said..:)

    You mean the Queen's English, don'tcha? Now that opens a whole can of
    worms. It would mean you'd have to start spelling things correctly too...

    colour
    honour
    centre
    tyre
    neighbour

    Somehow, I just don't think that's gonna happen. Not only did we REBEL
    against the tyranny of a King, we decided to drop a few "u's" on the way.
