    Hey all.

    I'll be replacing all the existing cabling on my ademco redo.

    I've purchased 2000' of 22/4, and am making up the harness(es) now.

    A question on the RGYB: Is there a convention for which colors are
    used? For example - door contacts which use only 2 of the 4 conductors
    - should I use red/green, yellow/black or some other combo? I realize
    from a functionality standpoint its a meaningless question, but if
    there is some sort of usual standard I'd like to follow it, in the same
    way I use blue/blue white for voice on cat 3.

    Also.... in my house the termination resistors are at the end of the
    run, but here at the shop they are in the can. Seems to me they would
    better serve their purpose at the end of the run, but what the hell do
    I know, I don't do this for a living. So, should they go at the end,
    the beginning, or it makes a difference not? If no difference, I'll put
    them at the end of the run, as I think they look like hell when in the
    panel.

    Also - any pics of a goodly wired residential panel? I've about 22
    zones in this job, and I'd like some close ups of any work someone is
    proud of.... I'm a former electrician, and without any other input from
    ya'll my install will likely end up done in breaker panel fashion.

    Thank ya kindly.

    Thanks Graham

    This install is in a 1 story bldg, with either attic/ceiling tile/open
    space above the main floor. When I installed the voice/data ckts, I
    found it was easier to run all the ckts on the floor, from the panel to
    the outlets. Then I zip tie all of it up, and simply lift everything
    (the harness) up into the attic and fish the individual ends down. Took
    me about 4 hours to pull 40 voice/data ckts this way.

    As it worked so well with that, I'm doing the same thing with the alarm
    wiring.
