Color code for FPL?

[gcimmino]

I looked at the wiring 101, but may have missed this:

Is there an "accepted" or code wiring color code for 4 cond. FPL? The cable I have has red, black, yellow and green conductors.

Obviously, as long as I'm consistant, it's moot. But if there's a "standard" out there, I'd like to follow it.

Thanks

Normal Fire Wire Color Code is:

Black
Red
Brown
Blue
Orange
Yellow
Purple
Green
Red/Black
Red/White

So if it is 4 conductor cable your colors should be black, red, brown, and blue. I have never seen red, black, yellow, green in fire wire. Are you sure it isn't phone wire?

Well, I'm not sure of much..

However, the cable is marked as Honeywell FPL/CL2 18ga. I believe this is the spec sheet.

So, is the red/black pair usually used for smoke power and the yellow/green for the signal (which pos/neg?) Or?

Thanks

I wonder if it is a different color code because it is shielded wire? I don't know what the convention is for this. It would seem logical to use red and black for power with yellow as zone + and green as zone - but I don't know if that is correct or not.

Bump, anyone know if there is a standard/code for these 4 colors? Thanks

Thanks. Just spoke to the electrician that did the pre-wire who confirms that this is the commonly accepted color coding.

All of mine is red + black + yellow (or white) + green, I use the black and red for power or for the zone on a 2 wire system and the yellow + green for zone in a 4 wire system. Optionally I will go out on a 2 wire zone with black and red and come back to the panel on yellow and green.
